Using the W. M. Keck Observatory located on the summit of Mauna Kea, Hawaii, astrophysicists at University of California have detected the faintest galaxy ever, born just after the Big Bang.
There are about 100 billion to 200 billion galaxies in the observable universe. For roughly 13 billion years they’ve swarmed around each other, colliding and merging, undergoing rapid star formation and suffering periods of drought, where no new stars are born.
Astronomers have managed to analyse a spectacular flare from a supermassive black hole at the center of galaxy 3C 279, a record flare that happened five billion years ago.
Using the Hubble Space Telescope, astronomers have investigated the relationship between monster black holes that power radio-signal-emitting galactic jets and galaxies that have undergone mergers.
Far off in the universe, there’s a remote galaxy that shines as bright as 300 trillion suns and according to NASA, it is currently the most luminous galaxy ever seen.
An international team of researchers using the 10m telescope at the W.M. Keck Observatory have discovered unusual class of galaxies, called ultra-diffuse galaxies, in distant space.
Billion years ago, galaxies like our Milky Way underwent an era of prolific star formation, churning out stars at a frenzy rate, 30 times faster than they do today.
Two Russian astronomers have spotted 11 homeless galaxies that have been flung out of their homes to wander out in deep space, millions of light years from their nearest neighbours.
Quasars are known to be super-energetic and compact regions surrounding a supermassive black hole at the center of a galaxy. Quasars usually get their luminosity and electromagnetic energy from the nearby black holes that spew back tons of energy in various forms while they feed on the mass from their surroundings.
Treasure seekers have found the haul of a lifetime, but it wasn’t in some ancient temple or mysterious island. Instead, it was in the sky.
Far away from Earth, the ongoing collision of dense galaxy clusters is creating a stunning show of radio waves. In the region, where clusters of hundreds of galaxies are colliding, these variety of objects are visible only to radio telescopes. Scientists created a ‘true colour’ image of the region to reveal what it would look like if humans could see radio waves, rather than just visible light.
