Nov. 4, 2026 NASA is exploring a daring plan to save the legendary Hubble Space Telescope from its eventual fiery plunge into Earth's atmosphere. After more than 35 years of groundbreaking discoveries ...

When two black holes collide, they can merge into one enormous black hole. But what if one black hole could do the opposite and split into two? A new theoretical study suggests that this strange ...

Astrophysicists think that the supermassive black holes (SMBH) we see in the modern universe are the result of a long, ...

Using Hubble in a new observing configuration, the team also identified a previously unseen warp in the dust halo surrounding Beta Pictoris. The distortion may result from the gravitational influence ...

The event horizon of a nonspinning billion-solar-mass back hole has a radius of 1.8 billion miles — the distance of Uranus from the Sun.
