Astronomers Catch Powerful ‘Zombie Star’ Speeding Through the Milky Way, Have No Idea Where It is From The Hubble Space ...

Magnetars are among the rarest—and weirdest—denizens of the galactic zoo. They have powerful magnetic fields and may be the ...

NASA is closely monitoring SGR 0501+4516, a rare and exceptionally powerful magnetar with a magnetic field trillions of times stronger than Earth's. This "zombie star" poses a significant threat due ...

While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star’s light and slowly ...

But a second analysis conducted in 2022, using more Hubble data, came to a different conclusion. This team refined the mass estimate to between 1.6 and 4.4 solar masses. Since that's generally too ...

A black hole, seven times the mass of the Sun and located nearly 5,000 light-years away, has been confirmed as the first to roam the cosmos alone.

By examining data from the Hubble Space Telescope and Gaia space probe, which were gathered from 2021 to 2022, the team discovered even more robust evidence.

There is also likely a forest of binary black holes, neutron stars, and white dwarfs. All of these emit gravitational waves as they gradually ... Astronomers have employed the Nuclear ...
