#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

A new cosmic test has finally, with CMB and large-scale structure data, become realistic: using the kinetic Sunyaev-Zel'dovich effect to test dark matter vs. MOND.

Messier 3. A globular cluster containing about 500,000 stars. It doesn’t have a cool “common name” and I find that sad. That means we get to name it, right? I propose Globby McGlobface. Submissions are open until May 8th. I’ll publish the best one in my very unscientific journal. 📷 Sony a7 IV, Z61 II, 2 hours. #Astrophotography #Space #Astronomy 🔭

This isn't a scene from Star Wars. What you're looking at is the Tarantual Nebula, and those beams come from the lasers installed on the telescopes of our Very Large Telescope Interferometer in #Chile. They create artificial stars 90 km above the ground to correct atmospheric turbulence, allowing the VLTI to observe faint targets. But why are four telescopes observing the same target?

I stopped paying attention to rocketry after Elon did a Nazi salute. So, I legitimately thought Blue Origin hadn't launched any New Glenn's yet. https://www.cbsnews.com/news/blue-origin-new-glenn-rocket-satellite-wrong-orbit/ Good thing I stopped paying attention I guess!

In happier news, it's been a great week for learning strange new things about the universe. A few highlights: The Rubin Observatory opened its eyes & immediately discovered 1900 asteroids, including the fastest-spinning large asteroid (once every 1.88 minutes!). https://noirlab.edu/public/news/noirlab2601/ #science #nature #space
