For practically as long as NASA's Hubble Space Telescope has circled Earth, astronomers have wanted to use it to see a comet as it's breaking apart. Many researchers have proposed ...

The researchers had initially selected a different target for Hubble.

C/2025 K1 (ATLAS) was on its way out of the solar system when it did the fateful thing that many comets do. Reading time 3 ...

In a stroke of luck, astronomers saw the comet C/2025 K1 (ATLAS) break into four or five fragments in November after it passed close to the sun.

NASA’s Hubble Space Telescope has captured a rare moment involving the comet C/2025 K1 (ATLAS) as it began breaking apart. Events like this are not often seen, mainly because comet fragmentation is ...

NASA and ESA have released new images from the Hubble Space Telescope of a comet breaking up as it exits the solar system, captured as part of study recently published in the journal Icarus. The ...

NASA’s Hubble Space Telescope got a rare look at the aftermath of two cosmic collisions — and helped scientists solve a decades-old mystery. Many years ago, scientists saw a dense, bright spot near a ...

The local universe may be expanding more slowly than previously thought, a discovery that could relieve a pesky discrepancy ...

In a happy twist of fate, NASA's Hubble Space Telescope witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings are ...

The discovery of CDG-2 began when a team of astronomers investigated tight groupings of stars called globular clusters, which ...

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors—a small, gas-rich galaxy visible to the ...
