Happy to support this excellent work on 2024 YR4, in which JWST 🔭 shows that this asteroid will not hit the Moon in 2032 after all - whew! (though it would have been fun to watch!) Great team led by @asrivkin.bsky.social

or also, i dunno, like maybe what you'd expect from an icy object that formed like 10–12 Gyr ago beyond the H2O ice line in a relatively cold, dense and well-shielded protoplanetary disk midplane? 😉

As a longtime advocate for a US-led ice giant mission, I’m simultaneously disappointed (from a US perspective) and delighted (from a basic science perspective)

"Fundamental science is a long game, and government departments and agencies can sponsor long-term projects, whether the goal is mapping the entire U.S. coastline or the entire human genome." Or building an advanced space telescope 🔭 to find out if humanity is truly alone in the cosmos.

Countless star trails appear as colorful brushstrokes spread across the night sky above the NSF–DOE Vera C. Rubin Observatory. This mesmerizing image was created using long-exposure photography, a technique in which a photographer allows light to enter their camera lens for a period of several minutes to several hours. The camera captures the subject’s movements, and the resulting image shows the flow of time in a single shot.

During its decade-long Legacy Survey of Space and Time (LSST) Rubin will use a technique known as difference imaging: equipped with the largest camera ever built, Rubin will image the southern sky every few nights. Scientists will stack the best images in each filter each year into ultra-long exposures and create template images of the southern sky. When this template is compared to individual images, scientists will be able to identify ‘movements’ in the night sky, such as new supernovae or the 'pulsations' of variable stars. After 10 years and thousands of exposures, Rubin will produce an unprecedented ultra-wide, ultra-high-definition, time-lapse record of our Universe — the ultimate movie of the night sky.

This image was captured by Hernán Stockebrand, a NOIRLab Audiovisual Ambassador.

NSF–DOE Rubin Observatory 🔭 has issued its first scientific alerts, marking a historic milestone in astrophysics. Expected to increase to seven million alerts per night (!!!), these first alerts start a new era of dynamic, real-time observation of the night sky. More: noirlab.edu/public/news/...

See Uranus’s rosy glow in its full 3D glory Fresh observations from the James Webb Space Telescope show how vivid auroras surge through Uranus’s tilted magnetic field

A cool thing in these JWST 🔭 Uranus infrared images -- ASIDE from the (artificially-blue) polar cap & the dynamic bright clouds -- is the imaging of the aurora! It is the reddish glow extending above the clouds (e.g. 10 o'clock in the image on the right) www.scientificamerican.com/article/new-...

Jupiter bonanza scheduled for JWST starting this Friday 🔭 - woo hoo! The teams are calling on amateur astronomers to assist with context imaging of the Solar System's largest planet.

Remember you don’t need a PhD to work in the space field. Sometimes
all you need is IT business experience. This might be YOU!!
