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 ...

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 ...

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 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 ...

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, ...

Ripples in space-time point to the merger of a neutron star with another mystery object. The object, which falls right within the mass-gap range, sheds light on a long-sought, murky realm. When you ...

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 ...

A leading gravitational wave observatory recently detected ripples in spacetime that scientists say came from the collision of a dead, superdense stellar remnant and an unknown object. The stellar ...
