cientists have just discovered what may be the largest black hole known to date.The black hole has a mass (量) of about 30 billion suns and sits at the center of a galaxy(星系), which is hundreds of millions of light-years from the Earth.Black holes are one of the most powerful for...
This is especially true because the galaxy that surrounds it is relatively small.Largest Black Hole Ever Found DiscoveredBillion Times the Mass of the Sun
A powerful telescope in Chile has imaged the largest yellow star ever discovered. The star, called HR 5171 A, shines 12,000 light-years from Earth in the center of a new image released today (March 12). Known as a "yellow hypergiant," The star is more than 1,300 times the diameter ...
Stephenson 2-18 is a red supergiant star of the spectral type M6. It is one of thelargest starsever discovered, with a radius of 2,150 solar radii. It is also one of the most luminous stars in the Milky Way and one of the most luminous red supergiants known. With an effective tempe...
Another study employs spectroscopy from the Sloan Digital Sky Survey together with the Legacy Surveys imaging to reveal the presence of active black holes in galaxies, and giving us a preview of a large population of active galaxies to be discovered with the DESI spectroscopic survey. ...
his artist's impression shows quasars scattered throughout the cosmic web in the early universe. (Image credit: ESO/M. Kornmesser') A spooky new image shows a web of bright galaxies aligned in the largest structures ever discovered in the universe. Scientists working with a telescope in ...
A‘normal’ galaxy The Wolfe Disk was first discovered by ALMA in 2017. Neeleman and his team found the galaxy when they examined the light from a more distantquasar. The light from the quasar was absorbed as it passed through a massive reservoir of hydrogen gas surrounding the galaxy...

To explore deep space is to come to grips with humanity’s ever-shrinking importance in the universe. In another shot to our cosmic ego, scientists have discovered a new superstructure, named Quipu, that stretches 1.39 billion light-years across and contains the equivalent mass of 200 quadrilli...
Either way, in addition to the inherent excitement of getting to study the largest “things” ever, analyzing superstructures such as Quipu has practical applications for our understanding of the greater universe. For example, superstructures can bend light...
