‘It’s going to be awesome’: How the Vera C. Rubin Observatory will survey space and time

Artist's rendition of asteroid Psyche

Could Psyche be the core of the planetesimal that struck Earth and formed the Moon?

This is an image of a globular cluster around our Milky Way. The authors of a new study think that what they see in the Cosmic Gems arc will become this object. Credit: NASA/ESA.

Unusual glimpse of Cosmic Gems could be a breakthrough for astronomers

A single crescent moon is a familiar sight in Earth's sky, but with Saturn's many moons, you can see three or even more. The three moons shown here are Titan (3,200 miles or 5,150 kilometers across), Mimas (246 miles or 396 kilometers across), and Rhea (949 miles or 1,527 kilometers across). This view looks toward the anti-Saturn hemisphere of Titan. North on Titan is to the right. Credit: NASA.

Why does Earth have only one Moon?

An artist impression of a Fast Radio Burst (FRB) reaching Earth. The colors represent the burst arriving at different radio wavelengths, with long wavelengths (red) arriving several seconds after short wavelengths (blue). This delay is called dispersion and occurs when radio waves travel through cosmic plasma.

Mysterious Cloverleaf ‘odd radio circle’ could be a merger of a dozen galaxies

This artist’s impression shows two stages in the formation of a disc of gas and dust around the massive black hole at the centre of the galaxy SDSS1335+0728. The core of this galaxy lit up in 2019 and keeps brightening today — the first time we observe a massive black hole become active in real time. Credit: ESO/M. Kornmesser.

Neil Armstrong was the first man on the Moon — but only a few pictures from the crew’s cameras show him on his historic moonwalk. In one of them (above), he is visible as a reflection in Buzz Aldrin’s helmet. Credit: NASA
