Here's an actual photo (well, a digital scan of a 70mm film photo, source: catalog.archives.gov/id/22592604) of NASA astronaut Bruce McCandless during his MMU EVA on STS-41B on February 7, 1984. I've always liked this one because he looks like he's having a good time out there.

Golden hour hits different above 2600 meters. ✨🌅 NSF–DOE Rubin Observatory basks in that sunset ✨glow✨ at its site on Cerro Pachón. And with over 300 clear nights on average per year here, that's a lot of sunset basking we get to do!

#NASAWebb is clearing up some mysteries about star formation thanks to its infrared capabilities—ideal for seeing the coolest, dimmest stars. ✨ Building on Hubble’s look at the Flame Nebula, Webb revealed new details, including the region’s low mass objects.

Eta Carinae is famous for a brilliant and unusual outburst observed in the 1840s. This visualization presents the story of that event and examines the resulting multiwavelength emissions and three-dimensional structures surrounding Eta Car today. youtu.be/z5P3tRPm9YI

Scientists have discovered a young protoplanet embedded in a ring-shaped gap around a forming star — revealed in part by University of Arizona's MagAO-X extreme adaptive optics system at the Magellan Telescope in Chile. The instrument is ushering in a next-generation ‘extreme AO’

The Long March rocket series includes 24 models, with 5 retired and 19 in service. Long March 3B is the most launched older model with 110 launches, and Long March 6A leads the newer generation with 18 launches. Source:m.weibo.cn/status/Q9FfZAF…

timelapse of comet lemmon with a million satellites

Noisy, but comet lemmon tonight 😍☄️✨ Between satellites and airplanes, there's so much traffic up there in those earlier hours of the night, it's hard to get any shots that don't have SOMETHING passing through 😑 #WV #StormHour #ThePhotoHour Spencer Adkins Brandon Butcher

Looks like the Moon just got a new (decent-sized) crater! Be interesting to see how the area shows up in LRO images.

In a powerful blend of history and modern technology, India’s Chandrayaan-2 orbiter has captured stunning high-resolution images of the Apollo 11 and Apollo 12 landing sites, offering fresh visual proof of humanity’s first steps on the Moon. The photos show the exact spots where

Bright galaxies like M83 are a favorite among amateur astronomers. This Hubble image provides a wealth of information about stellar formation—and death, spread across the galaxy’s 50,000 light-years: bit.ly/4qsgocE

This visualization examines the Hubble image of the Egg Nebula and showcases the shape and development of its three-dimensional components. There's more about the Egg Nebula in the news release: go.nasa.gov/4anDbQ9

We're throwing it back to Summer 2025! This NOIRLab #ImageoftheWeek shows NSF–DOE Rubin Observatory’s initial observations of the interstellar object Comet 3I/ATLAS☄️ Scientists expect that Rubin could detect dozens more visitors from other stars over the next decade 🔭

Sol de hoje em 3 modos de abordar o resultado final do processamento. ⚠️ AVISO. NUNCA OLHE DIRETAMENTE PARA O SOL SEM EQUIPAMENTO CERTIFICADO E SEMPRE FAÇA ISSO COM PESSOAL EXPERIENTE NESTE TIPO DE OBSERVAÇÃO. RISCO DE DANOS GRAVES À RETINA E ATÉ MESMO CEGUEIRA.

13 *real* photos showing the actual damage to the Apollo 13 service module, taken by Jim Lovell from inside the LM after separation, still 35,600 nautical miles from Earth. No AI slop needed—it looks scary enough as it is. "There's one whole side of that spacecraft missing."

A dark matter-dominated galaxy is hiding here! 🕶️ Hubble has helped discover one of the darkest known galaxies, CDG-2, which appears to be 99% dark matter. 1/2

Asteroids, supernovae, and black holes...oh my! ☄️🌀 In a single image, Rubin will detect thousands of changes in the sky — from objects in our Solar System to exploding or pulsing stars and actively feeding supermassive black holes, as well as surprises we can't predict yet! 💥
