This is a bright lunar impact flash that appeared at 20:56:20 on July 20, 2026 (848fps). Since the Moon has no atmosphere, it doesn't become a meteor or fireball; instead, it shines intensely at the moment when a meteorite collides and creates a crater. 📸 @dfuji1.bsky.social x.com/dfuji1/statu...

A rocket will hit moon on Aug 5 Falcon rocket will hit the moon on Aug 5 In Jan 2025, Falcon 9 rocket launched two missions toward moon: Blue Ghost and Hakuto-R. After the upper stage of the Falcon 9 rocket completed its boosting mission, it became just another piece of space junk.

#PPOD: NASA's Curiosity Mars rover captured these clouds just after sunset on March 19, 2021, the 3,063rd Martian day, or sol, of the rover's mission. The image is made up of 21 individual images stitched together and color corrected so that the scene appears as it would to the human eye. 🧪 🔭

Using NASA's James Webb Space Telescope (JWST), a team of Caltech researchers has observed Neptune's rings and three of those moons—Larissa, Galatea, and Proteus—and found that their composition is unique among outer solar system bodies. www.caltech.edu/about/news/n...

Neptune's Inner Moons May Be Shattered Remains of Ancient Icy Worlds

New findings from Caltech researchers suggest Neptune's smallest satellites formed from the shattered remains of an original moon system that was destroyed when Triton was captured by Neptune's…

Neptune's Inner Moons May Be Shattered Remains of Ancient Icy Worlds In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet's main rings. Paper www.science.org/doi/10.1126/...

JWST/ Near-Infrared Camera (NIRSpec) images of Neptune's moon Larissa and rings, acquired on two dates when Larissa was on opposite sides of Neptune. The bright spots are Larissa and the bright rings can be seen clearly. Neptune itself is positioned at the center and the calculated positions of Neptune's rings are overlaid in gray.

This is a super cool paper (and last chapter of her PhD thesis) from my now-graduated student @import-astrory.bsky.social I would explain more but, really, the headline kind of does the job.

An M1.9 flare is currently occuring from AR 4492 which is near the Sun's western limb. A very large CME is also lifting off which has a small chance of containing Earth-directed components. We will see what the coronagraphs reveal as the event is currently unfolding.

Asteroid (44) Nysa observed with the SHARK-VIS instrument of the Large Binocular Telescope on 15 February 2026 UTC. The asteroid’s tiny moon, S/2026 (44) 1 is marked with a pink arrow. Image credit: Kate Minker et al.

We are used to seeing weird shapes of small asteroids, but this is next level! look at the shape of 44 Nysa from Minker et al. This is 75 km volume-equivalent diameter object! Also it has a satellite! #planetSci 🧪
