This moth makes its epic migration navigating by starlight Bogong moths fly 1000 kilometers orienting to stars and the Milky Way, an ability never seen before in invertebrates

“The amazing astronomical abilities of this little creature,” Warrant told me, “are uniquely tied to an entire alpine world.”

I wrote in Science about a new study on bogong moths, which have neurons in their brains that seem to recognize the Milky Way and infer due south from its orientation.

The Space Telescope Science Institute's MAST archive contains 300 million astronomical observations from over 23 different missions.

Here is an animation showing how the archive has built up over time.

Felicidades @asuarezmascareno.com !!

This is why current AI is not going to make breakthrough science at any point in the near future. Humans will.

I have to admit it, working here is a dream job.

@NASA/Hubble is currently getting ready to perform one of our calibration experiments with the Advance Camera for Surveys (STRAYCOR) that will help us to improve the quality of the telescope's images and even make Roman Space Telescope even more sensitive to the darkest regions of the Universe.

The NASA planetary science fleet chart. It shows two spirals with missions to Moon/Mars and the Solar System. I’ve crossed off all of the missions that will be cancelled in the president’s budget… and there are a lot of them.

The NASA planetary science fleet chart if the president’s budget is enacted.

Here's NASA astrophysics, if I read the president's proposed budget correctly. 🔭

The Presidents Budget Request for NASA is out. It’s a bloodbath

Canceled are DAVINCI, VERITAS, Juno, OSIRIS-APEX, US participation in ExoMars and EnVision…

Huge cut to R&A. No funding to begin development of the Uranus Orbiter.

If you’ve ever cared about NASA, time to contact congress.

Planned reentry of the CRS-32 Dragon cargo ship at about 0545 UTC May 25. The large white area is where the jettisoned
trunk will burn up; the small area just off San Diego is where the capsule will splash down. Orange line is approx trajectory assuming several orbit lowering burns to match target

Venus as observed by NASA's Magellan spacecraft.

I respectfully disagree.

Two rows of three images. Top row is labeled Webb 11 July 2023 and the bottom row Keck 14 July 2023). The first column, labeled atmosphere and surface, shows two full-color images of Titan, appearing in mottled shades of yellow and brown with a blue haze around the edges. A bright spot near the top of Titan in each has an arrow pointing to it. The second column, labeled troposphere, shows two images in shades of orange. Each image is relatively featureless except for a bright spot near the top with an arrow. The third column, labeled stratosphere, also shows two images in shades of orange. The top image, taken July 11, is featureless and has no arrow. The bottom image, taken July 14, has a bright spot near the top with an arrow.

NEW: Saturn’s moon Titan has weather similar to Earth’s, but driven by methane evaporation and condensation. Astronomers have found evidence for clouds bubbling up over Titan’s northern hemisphere for the first time, using #NASAWebb and Keck observatory: webbtelescope.pub/3GofvQ1 🔭 🧪

Trump proposes unprecedented budget cuts to US science Huge reductions, if enacted, could have ‘catastrophic’ effects on US competitiveness and the scientific pipeline, critics say.

Trump proposes unprecedented budget cuts for US science in next fiscal year
NASA cut by 24%
NIH cut by 40%
EPA cut by 55%
NSF cut by 56%

Plus:

- Ending the Gateway Space station program, set to ensure human presence on the Moon in the coming decades.

- End green aviation research programs to reduce air pollution and fuel waste.

NASA Administrator Janet Petro has announced the following changes in the budget president request:

- End the International Space Station in 2030 to replace it with a private space station.

- End Orion, SLS, and the Artemis program.

- A 47% cut in NASA Science Program.

Two views of planet Mars on a black background of space observed by the Hubble Space Telescope. At left, text: December 28, 2024 20:00 UT. At right, text: December 29, 2024 13:18 UT. In both images, its atmosphere is clear and the surface appears detailed. Most of the planet is shades of orange. At left, the brightest orange area appears in the left half. At right, the brightest orange area is centered and takes on the rough shape of a sleeping mask. In both views, darker surface features are noticeable on the lower half of the planet. These have a mix of orange, blue, and gray hues. At the top and bottom, white regions mark the planet’s polar caps. The entire limb of the planet, its visible edge, has a blue hue. The blue doesn’t form an even circle at the edges, and appears thinner toward the left and right, and thicker in some areas.

The planetary nebula NGC 2899 is shaped like a single macaroni noodle, with its edges pointed up, but its edge-on central torus is semi-transparent in the middle. The top and bottom edges are thick and orange. The center is semi-transparent blue and green. The wider central region looks roughly like a moth, also filled with semi-transparent blue and green. There are two pinpoint-like white stars with diffraction spikes toward the center. Immediately below them, slightly toward the right, is a smaller blue orb, a central star. The next layer of gas and dust is whiter, with some thicker pillars that look like they are rising up at bottom center. The colour fades into reds and purples, and then to orange.

A tiny portion of the Rosette Nebula. Very dark gray material shaped like a V extends from just below top left all the way down to the lower right corner and back up toward the top right. It looks like thick smoke that has billowed out irregularly, thicker along the line from top left to bottom right, and looser on the piece that goes toward the top right. Behind the dark gray on the left side, from the bottom left to top center, there is dust that looks like arced claw marks that appears in light orange and yellow. The background at top left is hazier and some blues are covered in semi-transparent orange wisps, which makes sections take on green hues. In the bottom right, the background is bluer. There are a few bright red and purple stars scattered along the right half, most toward the bottom. The largest star is at right-center, just at the edge. It is red and has four diffraction spikes.

Barred spiral galaxy NGC 5335 observed by the Hubble Space Telescope takes up the majority of the view. At its center is a milky yellow, flattened oval that extends bottom left to top. Within the oval is a bright central region that looks circular, with the very center the brightest. In the bright central region is what looks like a bar, extending from top left to bottom right. Around this is a thick swath of blue stars speckled with white regions. Multiple arms wrap up and around in a counterclockwise direction, becoming fainter the farther out they are. Both the white core and the spiral arms are intertwined with dark streaks of dust. The background of space is black. Thousands of distant galaxies in an array of colors are speckled throughout.

Happy anniversary, Hubble! 🎂

Celebrate 35 years since this NASA/ESA space telescope was launched into orbit with four anniversary images! They roam from the planet Mars to dramatic images of stellar birth and death to a neighbouring galaxy.

Trump White House budget proposal eviscerates science funding at NASA “This would decimate American leadership in space.”…

The White House shares their proposal for NASA's next budget:

- A 50% cut in Science Programs.
- Close Goddard Space Flight Center.
- Ending Roman Space Telescope a year before launch.

If this is applied, this is effectively the end of NASA leadership.

Trump White House budget proposal eviscerates science funding at NASA “This would decimate American leadership in space.”…

Massive (68%) cut to NASA astrophysics proposed in WH budget. If this stands, it's the end of American pre-eminence in space science. arstechnica.com/space/2025/0...

Massive cuts to NASA science proposed in early White House budget plan The preliminary version of President Donald Trump’s budget proposal to Congress, known as a “passback,” would cut the agency’s science budget funding nearly in half.

First the rumour was a 20% budget cut. Then, 50%. Now the president's NASA budget is out and it's a 68% cut to astrophysics ($1.5B to $487M).

Even if this gets reversed in four years, we will *never* recover the missions, partners, people who will be gone.

Es una maravilla ver buena parte de la Península Ibérica de color verde vida, y con nieve en las montañas, en esta imagen tomada ayer por #Copernicus #Sentinel3 😍

Cuidemos de todo este agua, que el verano va a ser muy largo y caluroso!

Correction: NASA launched a mission (Crew-10) to allow the return of NASA astronauts whose mission was extended at ISS during a test flight mission as planned since September 2024.

Enough sensationalism.
