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 ...

EVANSTON, Ill. (CBS) -- Northwestern University astrophysicists were among those involved in an international research collaboration that has detected a gravitational-wave signal caused by a merger of ...

- Lagoon Nebula (M8) is an emission nebula in Sagittarius.

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 ...

Scientists have captured the first direct images of colliding objects in a neighboring star system. Astronomers have seen the aftermath of two powerful collisions within a 20-year period around a ...

The most distant celestial object ever observed, nicknamed Earendel, might just be a cosmic optical illusion. Discovered in 2022 by the Hubble Space Telescope, Earendel was initially identified as an ...

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 ...

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 ...
