Blood moon will rise May 15
The moon will turn red Sunday night but don’t worry. It’s a natural phenomenon.
For 90 minutes, viewers will see a total lunar eclipse, one of the longest such events in a decade.
Lunar eclipses occur when the Earth sun and moon align for the moon to travel through the Earth’s shadow. This happens only three times a year, because the moon’s rotation is tilted as it rotates our planet monthly, preventing it from entering the shadow.
The red color is caused by sunlight hitting the Earth’s atmosphere, scattering blue light while allowing only red light to pass through. It’s why this event earned the name blood moon throughout history, and flower moon because it occurs during spring when flowers are in full bloom.
In addition to changing color, the moon will appear larger in the sky as it enters its perigee or closest point to the earth. During the height of the event, it will be 225,000 miles from Earth.
Viewing the eclipse is easy and safe. Unlike during solar eclipse, you don’t need eye protection and a simple pair of binoculars will help you view some of the moon’s details. The eclipse will start at 8:29 p.m. PST and last until 9:53 p.m., weather permitting.

Another stunning shot of a black hole revealed
At the center of our Milky Way Galaxy lies something amazing. And unseen in detail until now—a black hole.
On Thursday, radio astronomers released a photo of the object, which is thousands of light years away from earth and so large that it is four million times greater than the Sun.
Black holes are so gravitationally dense that even light cannot escape them. The orange ring on the outside- called an event horizon-is caused by radiation.
The photo was created by the Event Horizon Telescope collaboration, the same scientific team that released a shot of a more distant black hole, M87, in 2019.
“Today, right this moment we have direct evidence that this object is a black hole, “said Astrophysicist Sara Issaoun of the Harvard and Smithsonian Center for Astrophysics in the science journal Nature.
Katie Bouman, a computational imaging researcher at the California Institute of Technology, agreed that the image was historic.
“We’ve been working on this for so long, every once in a while you have to pinch yourself and remember that this is the black hole at the center of our universe.”
Prior to release of the photos, scientists were only able to predict the presence of black holes through indirect observations and Albert Einstein’s Theory of Relativity.
To get the photo, collaboration scientists connected eight telescopes worldwide and began collecting data during five nights in April 2017. The data was so massive-4,000 terrabytes- that it could not be shared on the internet and had to be carried by airplanes on hard disks.
The newest photo is of Sagittarius A, which resides at the center of the Milky Way. The previous image was designated M87 for the galaxy in which is exists.

Living Worlds: an engrossing look at the search for planetary life
When astronomers gaze through telescopes, they are seeking more than a night -time view of a distant star or planet.
They look to answer a question that has puzzled humans for as long as they have been able to look into the heavens. “Are we alone in the universe?” Does life exist on other planets?”
The Morrison Planetarium’s newest show “Living Worlds” doesn’t answer that question definitively, but it does examine all of the possibilities in an imaginative and engrossing presentation that’s more akin an experience than an illustrated science lecture. It opened at the California Academy of Sciences Friday, Nov. 5.
It’s the latest offering from the planetarium’s science visualization department headed by Morrison Senior Director and Science Visualization visionary Ryan Wyatt.
The planetarium is the largest all digital domed screen of its kind and Wyatt’s team of a dozen high-tech storytellers have, in the past, taken audiences under the soil to see insect life, across living coral reefs and into the Chilean mountains to see how astronomy teams monitor the heavens.
But this project is by far the most compelling show yet, which gets its point across though sometime dizzying visual effects and a script that draws on current cutting edge astronomical research undertaken by NASA and other major science organizations.
To produce such a project, Wyatt his team involve some of the most distinguished scientists in the field including astronomers Jill Tarter and Nathalie Cabrol of the Search for Extraterrestrial Intelligence (SETI) and engineers from NASA’s Jet Propulsion Laboratory.
Some of the planetary probes shown in Distant Worlds are still on the JPL drawing board, but the team was able to bring them to life with a little imagination and the latest in computer imaging programs.
NASA officials were especially impressed with a sequence involving a snake-like robot that someday may burrow into underground water on one of Saturn’s moons, Enceladus.
“The collaboration was really rewarding,” said Jeron Lapre, senior technical director of the visualization studio, “We got to collaborate on the color scheme of the robot. They said when it gets approved, they might adopt that color scheme.”
“To think that a spacecraft would be going to the outer reaches of our solar system with our color scheme. How cool is that?” he said.
Special effects are fun but “Living Worlds” takes a serious look at the natural forces that helped bring about life on Earth and how those systems may be at work on planets and moons in our solar system.
Along with space-based telescopes, scientists can call on a variety of technologies that measure the chemical spectrum present in extraterrestrial atmospheres and compare that to those found on Earth. The show does a good job of presenting the possibility that such findings could indicate traces of life without becoming preachy or too technical.
Earth’s current crisis is also a part of the “Distant Worlds” story and the show ends with an optimistic view of a green Bay Area where humanity has created a biodiverse future.
It’s now an exciting time for astronomy, as new planets are being discovered in parts of the universe that were not viewable before, said David Grinspoon, senior scientist with the Planetary Science Institute.
“We are discovering the massive realm of other exoplanets that provide so many places where things like life may be unfolding,” he said, adding “It’s not an esoteric quest. It’s very much about understanding the history and limits of life on earth and trying to apply that elsewhere.”
After seeing the show, some viewers may conclude that life does exist elsewhere in the cosmos and will certainly know more about how scientists look for it.
Shannon Bennett, the academy’s chief of science is convinced.
“I know we are not alone,” she said. “We feel alone because we isolated in space and time but there’s life out there.”
Living Worlds is shown daily in Morrison Planetarium. Admission to the planetarium is free with paid entry to the museum. Tickets are distributed outside the dome the day of the performance.

Costly lunar space suits behind schedule

The white suit is designed to be worn on the Moon's surface while the orange suit will be worn by astronauts during space flight.. Photo courtesy NASA.
Mankind’s return to the Moon will take longer than anticipated, in part, because the astronauts don’t have a thing to wear.
On the lunar surface, that is.
Development of two space suits needed to plant another American flag in the lunar dust has taken longer than expected and the suits won’t be ready until 2025 at the earliest, according to a report by the NASA Inspector General’s office, reported in the Washington Post.
The space agency’s Artemis program had projected a lunar landing a year earlier. Artemis is just the first phase of a long-term program to land humans on Mars.
Not only are the two suits behind schedule, but they are the most expensive astronaut garments ever, costing in excess of $1 billion for the pair. And you thought you had high clothing bills.
Artemis is the first program to build new lunar suits since Apollo program astronauts Neil Armstrong and Buzz Aldrin thrilled live television audiences by strolling around the Moon’s Sea of Tranquility in 1969.
NASA describes the suits as small capsules designed to shield the wearers from the vacuum of space and the harsh conditions they will encounter on the darker portions of the Moon.
These new suits feature a more flexible torso that will allow astronauts to actually walk and kneel more easily. They are a far cry from the stiff outfits worn by Apollo crews which required them to hop around the surface.
Though NASA is in charge of designing and building the suits, at least 27 separate private contractors are supplying the parts. Numerous glitches have occurred during design and testing, leading the inspector general to conclude that “a lunar landing in late 2024 as NASA currently plans is not feasible.”
And the new suits will fit a variety of body sizes. That’s important because the first person to step on the moon this time will be a woman and critics have said NASA has traditionally designed suits just for men.
In fact, an ill-fitting suit was indirectly responsible for cancellation of the first all-women’s spacewalk outside the International Space Station in 2019. No alteration services were available at the time.

Earth helicopter makes historic flight on the Red Planet
|
More than a century since the Wright Brothers took to the skies, another American built flyer has gone where no machine has gone before-Mars.
Engineers at NASA’s Jet Propulsion Laboratory were celebrating Monday, April 19 as images of the Ingenuity helicopter hovering over the Red Planet reached Earth. The copter is the little brother of the Perseverance probe- the most advanced robotic explorer ever sent to the Martian surface- which landed on Mars Feb 18. The helicopter was attached to the belly of Perseverance but managed to get more than 200 feet away for its first experimental flight. At 3:34 a.m. eastern time or 12:33 Local Mean Solar Time (how Martians track time) the copter rose 10 fee into the air, hovered for 30 seconds before making a soft landing. Perseverance cameras captured the whole event and NASA released a video which was not available to JPL scientists in real time due to the distance between Earth and Mars. Engineers could not fly the copter with a joystick either, but Ingenuity was controlled by an autonomous program featuring algorithms that handled guidance, navigation and control systems. NASA officials were happy, to say the least. “Ingenuity is the latest in a long and storied tradition of NASA projects achieving a space exploration goal that was once thought impossible,” said Acting NASA Administrator Steve Jurczyk in a press release. “We don’t know where Ingenuity will lead us, but today’s results indicate the sky-at least on Mars-may not be the limit.” The helicopter has since conducted two more flights going higher and staying aloft longer. To honor the Wright Brothers, a piece of the Wright Flyer-the world’s first powered airplane- was placed inside the copter. NASA administrators also named the rocky spot of Martian soil which served as Ingenuity’s landing pad Wright Brothers Field. NASA has plans to eventually send humans to the Red Planet and this mini flight was designed to test if an aircraft could fly in Mars’ very thin atmosphere. |

NASA probe looks for signs of ancient Martian life
Photo/video NASA/JPL
There’s nothing like a landing on a distant planet to make NASA engineers jump for joy.
And they did, Thursday, Feb. 18, breaking into applause as the Perseverance rover touched down flawlessly on the surface of Mars.
“NASA works, this is what NASA does, “exclaimed one observer in the control center of the agency’s Jet Propulsion Laboratory in Pasadena, California.
The landing was the culmination of a seven month, 300 million mile journey for the remote-controlled vehicle, which will spend almost two years trying to answer one of humanity’s most burning questions: did life ever exist on the Red Planet?
The United States has landed probes on the planet before, but NASA and its elaborate public information division went all out to promote this mission as a game changer.
A video hook up in the JPL command center broadcast the event live on television and online, complete with an animated mockup of the spacecraft descending through the Martian atmosphere.
The camera focused on engineer Swati Mohan as she rhythmically called out the distance to the planet’s surface every few seconds. The tension was reminiscent of the breathless moments before NASA astronauts Neil Armstrong and Buzz Aldrin landed on the moon in July, 1969.
And finally the announcement was made: “Touchdown confirmed. Perseverance is safely on the planet Mars,’’ she said.
The anticipation of this latest robotic Martian mission is fueled by humankind’s fascination with the Red Planet and the possibility that life as we know it may have once existed on the fourth rock from the sun.
One billion years ago, Mars was hotter and wetter than it is today. The surface shows evidence that water was present, forming rivers and lakes that have since dried up. Today the planet is a cold, lifeless husk where temperatures plunge well below zero and the thin atmosphere teems with unbreathable carbon dioxide.
But, given that the planet once contained the building blocks of ancient life---water carbon and energy--scientists are eager to find out if fossilized life forms could be present in Mars’ soil.
Perseverance has landed in the Jezero Crater, which once was filled with water and adjacent to a river delta, the perfect place for life to have existed. The elaborate probe, which is as big as a sports utility vehicle, will extract soil, analyze it with a package of high tech instruments and transmit the data to earth.
It will also leave samples on the surface which will be picked up by another rover years later and, once the technology is perfected, a spacecraft will fly it back to earth for close-up analysis. Later this spring, engineers will also test the onboard “Ingenuity ”robotic helicopter to see if it can navigate the Martian atmosphere and act as a kind of scout during future manned missions.
The Martin surface is littered with present and former spacecraft which have made their contribution to America’s exploration of the planet.
In 1976, NASA sent Viking 1 and Viking 2 probes which transmitted photos for six years and conducted biological experiments but with inconclusive results. In later years, the rovers Sojourner, Spirit and Opportunity transited the Martian surface sending back 100,000 photos before being damaged in dust storms.
Two other NASA spacecraft are now active on the surface. “InSight” is studying the planet’s interior and has already discovered that Mars is often wracked by earthquakes. “Curiosity,” launched in 2012, is located in the Gale crater, analyzing rocks from an ancient lakebed.
It’s unknown if life ever grew on Mars, but if NASA officials are to be believed, we will someday. Plans call for a manned mission in the next decade and tech titan Elon Musk has said that humanity must be a “multiplanetary species” to survive. He envisions more than a million people living on the planet by the end of the century.

America returns to space from its own soil
SpaceX Capsule Dragon
May 20,2020
It was a day to celebrate the success of American technology and private enterprise. And who doesn’t like that.
The SpaceX two man crew in their Dragon space capsule, roared off the launch pad at 3:22 p.m. May 30, enroute to the International Space Station where it would dock and deposit astronauts Bob Behnken and Doug Hurley after a 19-hour flight.
A lot was riding on the success of the mission. Saturday’s launch was the first blast off of a space craft from American soil since NASA’s Space Shuttle program ended in 2011.
The flight was also a huge financial gamble for entrepreneur Elon Musk who wanted to prove that a privately-built rocket could provide the resources NASA needs to undertake two more audacious missions: returning humans to the Moon within this decade and landing astronauts on Mars sometime in the future.
I must admit to having kept my fingers crossed as the rocket roared upward. Like so many others, I remember seeing the Space Shuttle Challenger ascend skyward perfectly in 1986 only to watch it explore in a ball of flame seconds later, killing all the astronauts aboard.
Since the end of the shuttle era, NASA has relied on the Russian-built Soyuz system to shuttle its astronauts to the station. Over the years, the U.S. has paid the Russians a total of $80 million per seat for the flights. It is hoped that flying privately built American spacecraft will save the taxpayers a lot of money and encourage tech innovation on the process.
Sure enough, the rocket booster that pushed the capsule into the upper atmosphere was recovered after it landed on a drone platform in the ocean. SpaceX plans to reuse it in future flights.
Musk was ecstatic after the launch and well he should be. SPACE X was chosen over for this mission over rival aerospace firm Boeing because a freight version of the Dragon capsule has been successfully ferrying supplies to the space station. Boeing hopes to carry astronauts to the ISS in the company's Starliner capsule. But an uncrewed flight failed last year when the capsule became stranded in the wrong orbit and returned safely after circling the Earth for two days
Space X has also suffered from technical setbacks. A much larger rocket capable of carrying humans to Mars exploded on a SPACE X launch pad the day before, forcing engineers back to the drawing board.
NASA, which has an extensive public relations division, was happy too. The launch was available live on the Internet, with multiple cameras showing the capsule and its crew at every stage of the flight.
It was the most viewed Internet event ever, NASA communications administrator Bettina Inclan told a press conference.
“We’re still collecting the data but some of our metrics are saying that peak viewership for the joint NASA Space x Launch across all of our platforms was at least 10.3 million concurrent viewers-the most watched event we have ever tracked.”
However, that number represents only online viewers. The biggest audience for a space mission ever was the 600 million viewers who watched former Astronauts Neil Armstrong and Buzz Aldren land on the moon with Apollo 11 on July 20, 1969, according to Space.com.
Whether the good feeling engendered by the mission will encourage the American public in the long run is anyone’s guess.
The launch took place during the coronavirus pandemic which has killed more than 100,000 Americans and caused an economic downturn not seen since the Great Depression of the 1930’s.
The recent killing of an African American man by Minneapolis Police has caused nationwide demonstrations along with nighttime violence and looting.
Space program supporters insist that reaching for the stars in times of turmoil is nothing new. The Apollo program took place during the 1960’s when American was torn by civil rights conflicts and the nation’s involvement in the Vietnam War. The moon landing provided a break from the grim daily news and improved public morale, they insist.

Online planetarium show reveals South American observatories
Image driving up a dark, mountainous road to a place like no other.
It’s heaven for stargazers, where you can look up and see large portions of the Milky Way Galaxy with the naked eye.
For the world’s astronomers, it’s the gateway to the cosmos. Each night, teams of scientists take advantage of the ideal conditions to peer out into the universe with the latest high-tech visual and radio telescopes.
The story of this extraordinary system and the people who operate it is being told in “Big Astronomy, People, Places, Discoveries,” now being shown online by the California Academy of Sciences.
Financed by a grant from the National Science Foundation, “Big Astronomy” was created by the academy’s science visualization team headed by Ryan Wyatt, director of the Morrison Planetarium. Because the planetarium is closed due to pandemic restrictions, the show is being distributed on You Tube along with live interviews and other related events
Wyatt’s team travelled to Chile twice during 2019 to film at a series of high- altitude observatories run by the NSF and connected to research institutions in the United States.
Chile is the ideal spot for astronomy due to winds out of the Antarctic which create clear, cloudless skies in the surrounding mountains. The Atacama Desert, the world’s driest, is also ideal for radio astronomy and is home to the ALMA array which has been key to many astronomical discoveries.
Special emphasis was placed on the people who operate the system. To provide an accurate picture, the team conducted numerous interviews with everyone from astronomers to an employee who drives an enormous vehicle that moves radio telescopes.
“All the great discoveries that are made every day need a host of people,” Wyatt said. “There are a lot of careers involved. We wanted to tell the story of these people in Chile where that happens.”
Crew member Mike Schmitt was impressed by the relationships among the Chilean employees.
“I didn’t expect the community that was there.” he said. “It was like a family.”
Creating the show was a new challenge for the team which creates most its images with computer-generated graphics. Using the latest in SONY camera technology, the team shot live action of people and places along with time-lapse photography to illustrate astronomic phenomena. Wyatt said. Future shows will probably involve more photography, he said.
“We wanted to have more footage from the real world,” he said. “We wanted to climb that learning curve.”
Not that it was always easy. It rained when the team visited the world’s driest desert, and team members were limited by how long they could stay at the sites due to limits imposed by the system and the dangers of high-altitude exposure.
The Atacama site is at 16,000 feet and some crew members briefly suffered altitude sickness. Observatory employees have their blood pressure and heart rate checked regularly to avoid physical problems, Wyatt said.
Driving down the mountain roads could be challenging as well. An earthquake measuring more than 6.0 on the Richter scale hit after a day of filming at one mountain observatory, forcing the crew to get out of the vehicle and move large boulders that had fallen on the road.
“We realized there had been an earthquake and we had to get them out of the way,” Wyatt said.
“We thought there could be an aftershock so we kept going a dozen times before we got to an intersection. “
“Big Astronomy” is streamed on the show’s YouTube channel www.youtube.com/watch?v=fqsTqcIskZ8,. The video was created in 2021 when the planetarium was closed due to the COVID-19 pandemic, but is open now

It’s heaven for stargazers, where you can look up and see large portions of the Milky Way Galaxy with the naked eye.
For the world’s astronomers, it’s the gateway to the cosmos. Each night, teams of scientists take advantage of the ideal conditions to peer out into the universe with the latest high-tech visual and radio telescopes.
The story of this extraordinary system and the people who operate it is being told in “Big Astronomy, People, Places, Discoveries,” now being shown online by the California Academy of Sciences.
Financed by a grant from the National Science Foundation, “Big Astronomy” was created by the academy’s science visualization team headed by Ryan Wyatt, director of the Morrison Planetarium. Because the planetarium is closed due to pandemic restrictions, the show is being distributed on You Tube along with live interviews and other related events
