Star eating black hole spotted by Hubble and Chandra

NASA’s Hubble Space Telescope and the Chandra X-ray Observatory have collaborated to identify a potential example of an elusive category of black holes. Known as NGC 6099 HLX-1, this luminous X-ray source appears to be located within a compact star cluster on the outskirts of a massive elliptical galaxy.

Black hole moving spotted by Hubble

Like a scene out of a sci-fi movie, astronomers using NASA telescopes have found “Space Jaws.” Lurking 600 million light-years away, within the inky black depths between stars, there is an invisible monster gulping down any wayward star that plummets toward it. The sneaky black hole betrayed its presence in a newly identified tidal disruption event (TDE) ...

Phoenix galaxy cluster mapped by Webb

Researchers using NASA’s James Webb Space Telescope have confirmed how a massive galaxy cluster sustains high rates of star formation, resolving a long-standing mystery. This finding builds on more than a decade of studies conducted with NASA’s Chandra X-ray Observatory and Hubble Space Telescope, along with several ground-based observatories. Image credi...

Andromeda galaxy survey unveiled

On a clear autumn night, the farthest object visible to the naked eye can be seen without a telescope or binoculars. Located just northeast of the Great Square of Pegasus, it appears as a spindle-shaped haze with a bright center. This object is the Andromeda galaxy, the nearest galaxy to the Milky Way. The faint light from Andromeda left the galaxy 2.5 million years ago...

Closest quasar observations by Hubble

Amateur astronomers can search for a unique starlike object, known as 3C 273, which holds the record as the farthest target observable from Earth through a common-sized backyard telescope. Because 3C 273 radiates the light equivalent of trillions of suns, it can be seen over two billion light-years away. Today, it is known as the blinding bright core of an active galaxy...

Supermassive black hole duo found by NASAs Hubble Chandra

For all practical purposes, stars traveling across space never smash into each other. The ratio between a starlike sun's diameter and its distance to the next neighboring star is about 1:10 million. Galaxies do collide though. The separation between our Milky Way and neighboring Andromeda galaxy is a staggering 2.2 million light-years. That's a ratio of only 1:2...

JWST reveals dust in a galaxy 70 million light years away

Researchers at Newcastle University, using the James Webb Space Telescope (JWST), uncovered a dust veil in galaxy ESO 428-G14, 70 million light years away. Contrary to expectations, the dust is heated by gas collisions rather than radiation from the supermassive black hole. JWST reveals dust near a supermassive black hole This discovery highlights the complex...

Supermassive black holes are merging in the galaxy system ZS7

Astronomers have provided evidence for an ongoing merger of two galaxies and their massive black holes when the universe was just 740 million years old, using observations from the James Webb Space Telescope (JWST). This groundbreaking discovery highlights a significant period in cosmic history, revealing the farthest and earliest detection of merging black holes to dat...
