Here’s what deep-space objects are, what optics you’ll need to see them and how to plan your observing. When you purchase ...

The Solar system is bigger than NASA thought. There are a lot of huge objects at the edge of the solar system that we have not seen but can indirectly estimate. When astronomers say Kuiper Belt Object ...

Astronomers recently discovered the remains of a dead star that definitely set a record, even if they’re not sure which one. At somewhere between 2.09 and 2.71 times the mass of our Sun, the recently ...

Using images from a NASA telescope, three amateur scientists discovered a star-like object sprinting through space — so fast, in fact, it'll whiz right out of the Milky Way. This freak of nature, ...

Astronomers have discovered a highly unusual object within the Milky Way that emits both X-rays and radio waves in a synchronized cycle roughly every 44 minutes. The object, named ASKAP J1832−091, was ...

A team of scientists found a compact object 40,000 light-years from Earth that is either a very massive neutron star or an itsy-bitsy black hole, but they’re not sure which. The so-called mass gap ...

"Planetary-mass objects don't fit neatly into existing categories of stars or planets." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Breaking ...

How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic ...

The LIGO/VIRGO/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. It has now announced the detection of a signal indicating a ...

Sometimes astronomers come across objects in the sky that we can’t easily explain. In our new research, published in Science, we report such a discovery, which is likely to spark discussion and ...
