The Vera C. Rubin Observatory will capture enough detail to see a golf ball from 25km away.

Missions that return asteroid samples bring home more than just very expensive dust. These samples can provide valuable insights for scientists and commercial interests.
The Earth formed in a ring of debris around the Sun, like the one around Vega, a bright star, in this artist’s conception.

Learning about these interstellar objects could give us insights into other star systems.
This image overlays over 100 fireball images recorded between 2016 and 2020. The streaks are fireballs; the dots are star positions at different times.

Water-rich meteorites contain key ingredients for life, yet they barely appear in meteorite collections. Recent research using shooting stars may explain why.
A double plume created by the Chelyabinsk meteor that flew over Russia on Feb. 15, 2013. The shock wave caused damage and a small meteorite dropped.

Asteroids’ orbits around the sun may put them in collision paths with inner planets. We may have had a near-miss, but asteroids can pass by the Earth undetected.

In mid-February, asteroid 2024 YR4 was spotted and originally believed to have a 3.1 per cent of hitting Earth in 2032. Further calculations revealed this was not the case.

Two new studies show a briny, carbon-rich environment on the parent body of the Bennu asteroid was suitable for assembling the building blocks of life.
Dark comets accelerate through space but don’t have a dusty tail like most comets.

In 2017, astronomers found an object they’d never seen before. Now, it’s part of a growing category of elusive ‘dark comets’ – and we might find more soon.
WISE, NEOWISE’s predecessor mission, imaged the entire sky in the mid-infrared range.

Once the Wide-field Infrared Survey Explorer couldn’t survey widely anymore, NASA scientists switched gears and began using the spacecraft for planetary defense.
