The "Cosmic Horseshoe" is an Einstein ring, a system made up of a foreground galaxy whose mass is so great, it warps the ...

In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about five-and-a-half ...

Astronomers have discovered an ultramassive black hole 36 billion times heavier than the Sun in the galaxy LRG 3-757. This ...

This detection puts LRG 3-757’s black hole among the largest to ever exist. The biggest, called Ton 618, is estimated to weigh in at 66 billion times the mass of our sun and stretch up to 40 ...

DESI, which will be scanning the sky for five more years, is expected to observe around 40 million galaxies and quasars ...

Astronomers analyzing M87*, the first black hole ever imaged, have discovered that its shadow changes from year to year. The ...

Astronomers have discovered a record-breaking ultra-massive black hole, weighing 36 billion solar masses, at the heart of the ...

Astronomers also suspect that a class of objects called intermediate-mass black holes exist in the universe, although evidence for them is so far debatable. No matter their starting size ...

Now, though, using an instrument called the Dark Energy Spectroscopic Instrument or DESI, scientists have discovered a trove of these intermediate black hole candidates. They found 300 promising ...

More massive stars than the Sun have a very different life cycle and follow the right hand path in the diagram above: \({Nebula}\rightarrow{protostar}\rightarrow{main~sequence~star}\rightarrow{red ...

What do black holes look and sound like? How do they form? And what happens when a person falls into one? The answers to most any black hole question. By Laura Baisas By Laura Baisas By Laura ...
