A team of astronomers using a Yale supercomputer have determined for the first time that galaxies in denser environments are as much as 25% larger than their counterparts in less dense regions of the ...

The James Webb Space Telescope has detected a possible gas giant the size of Saturn in the stellar system nearest our own ...

Give them a constellation prize. A group of international scientists discovered three ultra-massive “Red Monster” galaxies capable of forming their own stars faster than the average nebula. The ...

"We thought they were basically all going to be fried because the entire universe turned into a vat of boiling oil." Astronomers have discovered a collection of tiny galaxies located roughly 3 million ...

A dramatic life-and-death game of planetary survival is taking place inside a gigantic cloud of gas and dust 1,500 light-years from Earth, and the outcome could have far-reaching implications for the ...

Astronomers utilized data from the Gemini South telescope in Chile and the James Webb Space Telescope (JWST) from NASA to detect silane (SiH₄) in the atmosphere of "The Accident." This simple molecule ...

Nearly a quarter of stars like the sun have planets about the size of Earth circling them in very close orbits, according to the first direct measurement of the incidence of such planets, researchers ...

Hubble can capture galaxies so far away their light took billions of years to arrive, yet Pluto remains a blur. The reason lies in size, distance, and the limits of resolution. It’s a paradox that ...

Mysterious radio waves might be winds from stars that exploded billions of years ago, according to new research. A new study suggests these strange, galaxy-sized waves could actually be galactic winds ...

The Sun is orbited by eight planets, at least five dwarf planets, tens of thousands of asteroids, and around three trillion comets and icy bodies. Although not all objects of the solar system are as ...

Astronomers poring over four years of data from NASA’s Kepler spacecraft have discovered a star that’s 11.2 billion years old and has at least five Earth-size planets. “We thus show that Earth-size ...
