In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster.
For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede.
NASA engineers are optimistic they’ll be able resolve a problem with the Hubble Space Telescope’s payload computer that knocked the observatory out of action on 13 June.
FRBs are powerful jets of energy that has mysterious origins. The research team performed a survey of eight FRBs, from which they were able to determine that five of them originated from a spiral arm in their host galaxies.
Astronomers using NASA's Hubble Space Telescope watched a mysterious dark vortex on Neptune (a storm, which is wider than the Atlantic Ocean) abruptly steer away from a likely death on the giant blue planet.
Scientists were surprised to find that this tenuous, nearly invisible halo of diffuse plasma extends 1.3 million light-years from the Andromeda galaxy and as far as 2 million light-years in some directions.
Using known distances of 50 galaxies from Earth to refine calculations in Hubble's constant, astronomers estimates the age of the universe at 12.6 billion years, different to the value of 13,8 billion years.
The red dwarf Proxima Centauri, just 4.2 lights years away. Recently, U.S. astronomers using data collected from the Hubble Space Telescope 25 years ago, have confirmed the presence of an exoplanet Proxima Centauri c.
The Hubble Space Telescope has captured two images showing Atlas, originally up to 180 metres across, has broken into as many as 30 pieces, each about the size of a house.
The object, called Fomalhaut b, was first announced in 2008. It was clearly visible in several years of Hubble observations that revealed it was a moving dot. Now it has vanished and scientists seek for a plausible explanation.
30 years ago the Hubble Space Telescope blasted off the launch pad aboard the space shuttle Discovery, ushering in a new era for astronomy that has transformed our understanding of the Universe around us.
Scientists using the Hubble Space Telescope have detected quasars sending outbursts of energy roaring through their galaxies, according to new research.
As if black holes weren't mysterious enough, astronomers have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, 130 million light-years away.
Hubble’s latest contribution comes in the form of a deep-sky mosaic image that was constructed using 16 years’ worth of observations. Known as the “Hubble Legacy Field“ it contains roughly 265,000 galaxies.
It is the sixth storm scientists have been able to document since 1989 when NASA's Voyager 2 probe first flew past Neptune, but it is the first whose birth and development was documented.
