Comet C/2022 E3 made a close pass by our planet in January, and a new video captures its incredible journey in 4K resolution.
Our solar system is filled with planets, asteroids, comets, the sun and more, making it a wealth of discoveries waiting to be found. See the latest discoveries from across our solar system here.
The velocity of interstellar objects passing through our solar system, like 'Oumuamua, can be correlated to their chemistry and the type of star they came from.
A new video shows off the sun's incredible power. A 'solar tornado' erupted from the surface in April, and you can watch it in 4K resolution.
New observations of the sun have revealed never-before-seen meteor-like fireballs raining down as shooting stars on the surface of the sun.
A supernova that erupted when a massive star died could have destroyed our infant solar system — if it weren't protected by a cocoon of molecular gas.
The cold and mysterious Oort cloud at the edge of our solar system may be hiding a rogue exoplanet, new research suggests.
The core of Jupiter's ocean moon Europa might have formed billions of years after the rest of it did, if indeed it has formed at all, a new study finds.
Saturn is once again the solar system's "moon king," snatching the crown back from Jupiter after the discovery of 62 new moons. Saturn now has a whopping 145 known satellites.
The action 12,000 light-years away may presage what happens to Earth about 5 billion years from now.
The dark skies of the new moon will offer skywatchers the chance to spot Ceres tonight (March 21), as the dwarf planet reaches opposition.
Pioneering American astronomer Maria Mitchell is the star of a children's book using an ancient language she happened to know: Latin.
The James Webb Space Telescope (JWST) has dazzled us plenty already, but the best is yet to come from the observatory, mission team members say.
The vast, swirling ocean within Jupiter's moon Europa may be affecting the rotation of its icy crust, scientists say.
A study simulated what would happen if a super-Earth orbited in the middle of our solar system, and the results are chaotic.
A planet-forming disk around a distant star has revealed an abundance of water that may indicate the solar system's water is older than the sun.
NASA's Interstellar Boundary Explorer (IBEX) is back to normal operations after controllers successfully reset its computer March 2, NASA said.
Astronomers interpret the spectra of 10 well-known dark asteroids and find them to be water-rich like the dwarf planet Ceres.
NASA's Interstellar Boundary Explorer (IBEX) reset its flight computer Feb. 18 and has been unresponsive to commands ever since, agency officials said Friday (Feb. 24).
Venus and Jupiter should make for a very striking visual spectacle, no doubt attracting the attention of even those who don't give more than a casual glance at the night sky.
