Data from the Kepler #space telescope suggest there may be as many as 300 million potentially habitable planets in our galaxy alone.

We may never have evidence proving whether intelligent life is somewhere out there, but - as Carl Sagan once wrote, “If it’s just us, seems like an awful waste of space.”

This dead star is bursting back to life

It would appear that a distant star has sprung back to life after its explosive death, blasting out repeated energetic flares over a period of several months that are like nothing astronomers have seen before.

Not Dead Yet.... Twas But A Flesh Wound?

For decades, astronomers have dreamed of setting up an observatory on the far side of the Moon. I read about it as a kid. Now it's happening!

The LuSEE-Night radio telescope is under construction, and is scheduled to land on the lunar farside in 2025. It's a pathfinder for a much bigger radio telescope that would follow. #space #nasa #science

This artist’s rendering shows LuSEE-Night atop the Blue Ghost spacecraft scheduled to deliver the experiment to the far side of the moon. Firefly Aerospace

Every minute of this video is excellent.

Listen to our friend Bryan Murphy telling @joeltelling (ahahaha) all about the Raspberry Pi-powered ISS Mimic 🛰️

(There's a cool story about the first all-female spacewalk in there too)

Last week some of us headed out to the small satellite conference in Utah, and some of us built ground stations, and a good time was had by all! #smallsat #cubesat #astropi #space

Born in 1928, Vera Rubin set her sights on Princeton, but they wouldn’t accept female grad students in astronomy. So she earned her master’s from Cornell & PhD from Georgetown.

In 1965, Rubin became the 1st woman allowed to observe at the Palomar Observatory. She went on to find evidence for the existence of dark matter.

In 1993, Rubin was awarded the National Medal of Science. But curiously, she was not awarded a Nobel Prize. #HistoryRemix #science #space #history

I've seen a lot of pictures of Saturn, but there's something really magical about this new raw image from JWST.
Pixel noise + filter selection make the planet vanish -- just a set of rings floating in space.

Our sun is big. It’s 864,000 miles or 1,392,000 km in diameter. Or 109x wider than Earth. But it’s also an average sized star.

Some stars are much bigger.

Betelgeuse, in the constellation Orion, is a red supergiant star ~700x the size of the sun.

If we replaced our sun with Betelgeuse, it would stretch past Jupiter's orbit. #space #science

Born in India in 1962, Dr. Kalpana Chawla became the first Indian woman in #space in 1997.

In 2003, she was on the Columbia, when insulation broke off, depressurizing the shuttle. All 7 crew members died.

7 asteroids + 7 hills on Mars were named after them. #HistoryRemix #science

“When you look at the stars & the galaxy, you feel that you are not just from any particular piece of land, but from the solar system." - Chawla, 1997

The history of Earth as the length of a human’s outstretched arm - representing 4.5 billion years of time.

At this scale, humans emerged so recently that we could be filed off from a microscopic slice at the very tip of a fingernail.

DEEP TIME: If the timeline of Earth were mapped onto the human arm, it would begin around the shoulder where the earth formed about 4.5 billion
years ago. Animals originated within the palm, but the myriad forms alive today exploded onto the scene around the first knuckle, in the Cambrian period.
Blocks along the fingers represent the periods that followed, such as the Jurassic (dinosaurs) and the Cenozoic. Humans evolved at a microscopic
slice at the tip of a fingernail. Infographic by Katie Scott from original article in Nautilus.

If we calculate how many grains are in a teaspoon of sand (an average) & multiply that by the amount of sand estimated on every beach & desert in the world, we get (roughly) seven quintillion, five hundred quadrillion grains of sand on Earth. #space #science

Meanwhile, there are ~70 thousand million, million, million stars in the observable universe - a figure vastly surpassing all of those grains of sand. The universe is immense, breathtaking & beyond imagination ✨
Detail of the globular cluster M92 captured by Webb’s NIRCam instrument. This field of view covers the lower left quarter of the right half of the full image. Globular clusters are dense masses of tightly packed stars that all formed around the same time. In M92, there are about 300,000 stars packed into a ball about 100 light-years across. The night sky of a planet in the middle of M92 would shine with thousands of stars that appear thousands of times brighter than those in our own sky. The image shows stars at different distances from the center, which helps astronomers understand the motion of stars in the cluster, and the physics of that motion. Download the image detail of M92 from the Space Telescope Science Institute. Image credit: NASA, ESA, CSA, A. Pagan (STScI).

I've been following @APoD for a while now and every time they post one of those gorgeous #space pics my brain just can't process that this is really how incredible space is. #Andromeda #galaxy

Happy that the first exoplanet discovered accidentally by Dale Frail and Aleksander Wolszczan in 1992 is included. They were not even mentioned when other #astronomers were awarded the Nobel prize for the discovery of exoplanets. And yet the discovery ended up showing exoplanets can show up in strange places.

As of March 2023, 72 #women have flown in #space.

Of these, 44 have worked on the International Space Station as long-duration expedition crewmembers, as visitors on space shuttle assembly flights, or as space flight participants on short-duration missions.

In 1977, NASA began looking for women astronauts.

Sally Ride spotted an ad about it in the Stanford school newspaper & applied. She was one of six women chosen.

In 1983, Ride became the first American woman to travel into #space. Her role as a mission specialist was to work a robotic arm to move satellites.

Ride went on to teach at UC San Diego & worked to promote women & girls in STEM. She also wrote children’s books about exploring space. #HistoryRemix

I’m always amused that when referring to the behaviour of objects that are very far away, as in the 1,900 light years here, we use the present tense 😆

“There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.”

— Carl Sagan, Pale Blue Dot, 1994 #science #space
This image of Earth is one of 60 frames taken by the Voyager 1 spacecraft on February 14, 1990 from a distance of more than 6 billion kilometers (4 billion miles) and about 32 degrees above the ecliptic plane. In the image the Earth is a mere point of light, a crescent only 0.12 pixel in size. Our planet was caught in the center of one of the scattered light rays resulting from taking the image so close to the Sun. This image is part of Voyager 1's final photographic assignment which captured family portraits of the Sun and planets. Credit: NASA / JPL

We are still at #Space Center Houston's SEEC conference, and shoulder-rubbing with astronauts leaves little time for blogging. So we have borrowed this space-themed item from the latest issue of HackSpace Magazine in which they show us some cool homemade rockets.

NASA doesn’t usually allow animals in portraits.

But in 2009, astronaut Leland Melvin snuck his adorable rescue dogs, Jake & Scout, into Johnson #Space Center for his official picture.

In addition to going on 2 space missions, Melvin had been drafted into the NFL. He’s now an advocate for STEAM education & animal welfare.

Sadly, Jake & Scout passed away, but when Melvin published his 2017 memoir Chasing Space, he chose this wonderful photo for the cover. #HistoryRemix

There’s more on losing the stars today from @sciencemagazine & the news isn’t encouraging:

“Light pollution is drowning the starry night sky faster than thought” #space #svience #nature /2

In 1952, Katherine Johnson heard there were open positions at the all-Black West Area Computing section at the National Advisory Committee for Aeronautics’ (later NASA) Langley laboratory.

With far too many accomplishments to list, her work was fundamental to marking a turning point in the space race with the Soviet Union.

In 2015, President Obama awarded Johnson the Presidential Medal of Freedom. She passed away in 2020 at 101. #history #space #HistoryRemix

Over 80% of the world’s population & 99% of Americans & Europeans live under "sky glow," where light pollution affects wildlife, human health & our ability to observe celestial objects.

As we lose the chance to look up & peer back in time at once vivid stars, we risk forgetting our place as a single species in the magnificent symphony of life. #space #science #nature #SharedPlanet
NASA image of the Perseid meteors in the night sky. The Perseids are debris remnants of Comet Swift-Tuttle, which takes 133 years to orbit the Sun once. The meteors often leave long “wakes” of light and color behind them as they streak through Earth's atmosphere. They’re also known for their fireballs, which are larger explosions of light and color that can persist longer than an average meteor streak.

This photo was taken Wednesday, Aug. 11, 2021, in Spruce Knob, West Virginia.

Love the info behind this image but I don't think I'll be using this as my next #NASA #space wallpaper 😉

We're working on lots of new stuff in Orion's End, ready for an exciting new trailer reveal in January. There will be new planets, new minigames, new characters. We're pretty excited.
