Happy #MayThe4th ! Here's a photo I took at @esoastronomy@mastodon.social 's Paranal Observatory in #Chile, with one of our 8-m telescopes aiming its four lasers at the Large Magellanic Cloud, a small galaxy orbiting the Milky Way. The lasers excite sodium atoms high up in the atmosphere, creating artificial "stars" whose twinkle we can measure in real time to correct atmospheric turbulence and get super sharp images. This is how it works: https://www.youtube.com/watch?v=g_QC2cLroDc #StarWars #StarWarsDay #astronomy #space

Finished two more 6x6” minis! I’m really on a roll this week. Original art, only $140 each + shipping, ships immediately. Please boost and share! Solo artist trying to support myself! 🙏😊 @Curator@mastodon.art #ArtForSale #MastoArt #FediGiftShop #space #scifi #abstractart #geometricart #geometricabstraction #homedecor

Are we alone? The great folks at Skeptoid have a kickstarter for their next feature film and the trailer looks great! 💫🔭 They had me at Carl Sagan: http://kck.st/4cFGFzO #space

Scientists have known for a long time that so-called “ice planets” like Uranus and Neptune are composed of some pretty weird materials. But recreating the conditions that create those materials is next to impossible. This is where simulations come into play. @ScienceAlert@flipboard.com has more, including what could be hiding in our solar system: https://flip.it/TxxpUF #Science #Space #SolarSystem

Looking at a galaxy 50 million light-years away through your telescope, every human worry shrinks to nothing. Deep-sky imaging doesn't just capture beauty; it confronts you with an universe utterly indifferent to your ambitions. #astrophotography #cosmicperspective #space

#PPOD: The colors in this image from the NASA/ESA Hubble Space Telescope tell a story about density in the Trifid Nebula, a star-forming region about 5000 light-years from Earth. The top left, where it is bright blue, has the least dust. Here, powerful ultraviolet light stripped electrons from nearby gas, creating a glow, with winds creating a bubble by clearing out surrounding dust. Credit: NASA, ESA, STScI. Processing: J.

It might be time to dust off your old solar system mnemonics. NASA chief Jared Isaacman says he wants to make Pluto a planet again. Space.com has more. Share your mnemonics below (we're "My Very Early Morning Jam Sandwich Usually Nauseates People"). https://flip.it/gaWuiI #Space #SolarSystem #Pluto

The White House announced a plan to cancel over 50 #space missions as part of a devastating 46% cut to #NASA #science.

The proposal would likely eliminate thousands of jobs at an agency that has just launched astronauts to the #Moon for the first time in decades, and dozens of other space missions would see their operations reduced or slowly wound down to a halt.

The following missions are to be cancelled:

  1. The Habitable Worlds Observatory being built to search for #life on dozens of Earth-like planets beyond our Solar System while addressing fundamental questions about our #Universe.

  2. OSIRIS-APEX capitalizes on the exceptionally rare 2029 Earth flyby of the potentially hazardous #asteroid #Apophis to advance planetary defense strategies and reveal how Earth’s #gravity alters an asteroid’s surface and interior.

  3. The ExoMars Rosalind Franklin rover will deliberately search for signs of life on #Mars by analyzing the composition of samples collected from as deep as 2 meters below the surface.

  4. The DAVINCI mission is an atmospheric probe that will be deployed to our sister planet, #Venus, and provide the first detailed measurements of the composition and chemistry of its #atmosphere.

  5. Initially focusing on #Jupiter’s interior, atmosphere, and aurora, #Juno is already orbiting Jupiter and has expanded during its extended mission to be a full system explorer capable of investigating the Galilean satellites, rings, inner moons, radiation belts, and boundaries of Jupiter’s magnetosphere.

  6. VERITAS will create unprecedented, global, high-resolution datasets of Venus designed to answer a fundamental question for rocky #planets: how did Earth and her twin Venus evolve into two entirely different examples of planetary #habitability?

A great interview with @sundogplanets@mastodon.social here: https://thenarwhal.ca/space-junk-falling-50th-parallel/ - very good reporting! everything that’s in low Earth orbit, which is most of the satellites — including all of the 10,000-plus Starlink satellites — at the end of their life, they get burned up in Earth’s atmosphere, because it’s convenient. And so far, it looks like Starlink is actually doing a pretty good job of burning up. Funny, but painfully so. And, for scale: There was a period of time, about six months, where Starlink burned up 500 satellites. That’s around three per day. In that time period, they exceeded the natural infall rate from meteorites by at least twice as much — so, adding at least twice as much aluminium as what naturally comes into the atmosphere every day for six months And it mentions Fedi's favourite Senator @Paulatics@mstdn.ca and the inquiry she launched https://sencanada.ca/en/senators/simons-paula/interventions/689271/37 Thanks for this great reporting, @thenarwhal@mstdn.ca ! #space #spaceJunk #spaceX #satellites #CDNPoli

Over 70% complete, our ELT is glowing in the #sunset light of the Atacama Desert in #Chile, surrounded by massive cranes hard at work to get this telescope up and running. With the first light planned for the end of the decade, the ELT and its groundbreaking 39-metre main mirror will take on some of the biggest challenges in #astronomy and, ultimately, help us understand our place in the #Universe.

Wow, they sewed the Apollo spacesuits with TREADLE SEWING MACHINES MIT Press: The Bra-and-Girdle Maker That Fashioned the Impossible for NASA "...Key to these demands were NASA’s painstaking engineering standards, which pushed the very limits of the equipment and seamstresses’ own techniques. The tolerances allowed — less than a 64th of an inch in only one direction from the seam — meant that yard after yard of fabric was sewn to an accuracy smaller than the sewing needle’s eye. To achieve such precision, many women used a modified treadle that, instead of starting and stopping a Singer sewing machine’s operation, fired one stitch per footfall through the multiple layers of a suit’s surface. ..." h/t @wtrmt@mastodon.social https://thereader.mitpress.mit.edu/the-bra-and-girdle-maker-that-fashioned-the-impossible-for-nasa/ #space #nasa #sewing
