Apr 4, 2023 · Astronomers have discovered two new black holes that are the closest ones to Earth known, and also represent something that astronomers have never seen before. The black holes, designated Gaia...

Apr 17, 2024 · Artist’s impression of the system with the most massive stellar black hole in our galaxy. The Milky Way has a big newfound black hole, and it lurks close to Earth! This sleeping giant was...

Jul 10, 2024 · Hubble has discovered a black hole "frozen in time" that's the closest massive black hole to Earth. The intermediate-mass black hole is a "missing link" between smaller and vastly...

Sep 8, 2020 · A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of …

Sep 23, 2019 · A black hole is an extremely dense object in space from which no light can escape. While black holes are mysterious and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity.

6 days ago · These new observations confirm that M87*'s rotational axis is pointing away from Earth. What's more, the outermost ring of plasma is probably swirling counter to the black hole's spin, the team found.

Mar 5, 2023 · This dormant black hole is about 10 times more massive than the sun and is located about 1,600 light-years away in the constellation Ophiuchus, making it three times closer to Earth than the previous record holder.

Sep 12, 2023 · Astronomers may have discovered that the closest black holes to Earth could be lurking in the Hyades Cluster, which sits only around 150 light-years from the sun. In fact, these black holes...

May 8, 2024 · The event horizon isn’t a surface like Earth’s or even the Sun’s. It’s a boundary that contains all the matter that makes up the black hole. There is much we don’t know about black holes, like what matter looks like inside their event horizons. However, there is a lot that scientists do know about black holes.

Jan 13, 2025 · Most telescopes can rather easily identify face-on supermassive black holes, though not edge-on ones. But there’s an exception to this that the authors of the new paper took advantage of: The torus absorbs light from the central source and reemits lower-energy light in the infrared range (wavelengths slightly longer than what human eyes can detect).
