Astrophysicists suggest our galaxy may lie inside a "cosmic void" - offering a new explanation for the universe’s conflicting ...

Just the third-ever confirmed interstellar object has been detected in our solar system. Here's what we know. (Spoiler: It's ...

Images of the cosmos, such as the James Webb Space Telescope’s deep space snapshot, make space look chock-full of stuff. In the grand scheme of things, it is, but all those stars, galaxies, planets, ...

Are we living in a cosmic void? New theory suggests our galaxy sits in a giant hole warping the universe's expansion.

The event, titled "Out of This World," will feature the Massapequa Philharmonic performing composer Gustav Holst's masterwork ...

If gravity reversed on the sun, McCluskey said he’d be scared because it is the only thing keeping the sun together. Nuclear fusion, inside the sun, pushes outward. Without gravity, the sun would ...

Why do we have a special day to celebrate space rocks? On June 30, 1908, a massive explosion over Tunguska in Siberia flattened approximately 2,150 sq.km of forest. This was attributed to the airburst ...

The birth of a new star seen in 1054, bright enough to dazzle humanity and visible for 20 days. An incredible cosmic event ...

Astronomers have discovered the strange dance that leads to the creation of rare "double hot Jupiters" in binary star systems ...

Have you ever wondered why all the planets in our solar system orbit the Sun in roughly the same flat plane? This fascinating phenomenon isn’t a coincidence but a direct result of how our solar ...

The eclipse measurements of 1919, for example, which established that gravity bends light’s trajectory, have inspired a successful technique now used for finding distant planets.

Self-gravity – the gravitational force that holds sufficiently massive objects together – allows gas planets to maintain their form in the vacuum of space.
