Small-scale concentrations of dark matter produce lensing effects that are 10 times stronger than expected, a new study found.
A dim patch in an otherwise bright galaxy is the epicenter of a supermassive black hole whose mass is 40 billion times greater than that of the Sun.
NASA's space telescope was looking for new stars when it came across a happy accident.
You'll feel very, very small after reading seeing this image.
The gargantuan cluster is 9.8 billion light years away from us, houses at least 27 galaxies and has a combined mass equal to 400 trillion Suns.
This year Hubble will embark on one its most ambitious projects yet, as it’s scheduled to glimpse farther away into the Universe than ever before. Six new “deep field” images are slated, and recently astronomers at Hubble have delivered the first to the public. The image reveals extremely faint, tiny galaxies that may be more […]
Each of NASA’s Great Observatories – Hubble, Spitzer and Chandra – have been designed to peer through the Universe in a characteristic manner. The telescopes have provided along the years massive amount of astronomical data and have helped scientists make important discoveries. What if you combine each of the telescopes’ strong points to assemble one […]
Whenever a massive object, with an equally massive gravitational pull, like black holes or galaxy clusters, falls between an observer, say a telescope, and a distant target in the background to be observed, than a gravitational lens is formed. Light emitted from the distant object gets twisted by the massive object, and ends up distorted […]
The ever scientifically productive Hubble just came out with another gem that will help scientists unravel the mysteries of the Universe, after the telescope snapped a photo of a couple of galaxy far, far away, wrapped together in a cosmic dance which most likely led in in the forming of a galaxy cluster – the […]
Galaxy clusters are the biggest stable structures in our Universe that we know of, typically containing 50 to 1000 galaxies. El Gordo Seven billion light years away and two million billion times heavier than our Sun lies El Gordo – which is Spanish for ‘the fat one’. Astronomers reporting at the 219th American Astronomical Society […]
