Astronomers Detect Most-Distant Galactic “Wind” of Molecules To Date
Astronomers using ALMA, with the aid of a gravitational lens, have detected the most-distant galactic “wind” of molecules ever observed, seen when the universe was…
Hubble Telescope Reveals Most Distant Star Ever Observed
Astronomers using the NASA/ESA Hubble Space Telescope have found the most distant star ever discovered. The hot blue star existed only 4.4 billion years after…
Distortion of Space-Time Helps Astronomers Set New Magnification Record
Extremely distant galaxies are usually too faint to be seen, even by the largest telescopes. But nature has a solution: gravitational lensing, predicted by Albert…
“Cosmic Snake” Reveals the Structure of Distant Galaxies
An international team of astronomers has studied the image of a distant galaxy, 6 billion light-years away from us, warped and stretched by strong gravitational…
Nearby White Dwarf Star Helps Confirm Einstein’s General Theory of Relativity
A Nearby white dwarf star helps confirm Einstein’s General Theory of Relativity and the history and evolution of galaxies such as our own. Albert Einstein…
Hubble Telescope Views Universe’s Brightest Galaxies
Using gravitational lensing, Hubble has captured unique close-up views of the universe’s brightest infrared galaxies – which are as much as 10,000 times more luminous…
Hubble Telescope Views the Many Galaxies of Abell 370
Hubble uses the power of gravitational lensing to get a better look at galaxy cluster Abell 370 and its several hundred galaxies that are tied…
Astronomers View Hubble Images of a Gravitationally Lensed Type Ia Supernova for the First Time
Using the Hubble Space Telescope, a team of astronomers analysed the multiple images of a gravitationally lensed type Ia supernova for the first time. The…
New Research Supports Faster Than Expected Expansion of the Universe
A team of astronomers used the Hubble Space Telescope and galaxies as giant gravitational lenses to make an independent measurement of how fast the Universe…
Astronomers Discover Distant Radio Galaxies via Gravitational Lensing
A new study details how a team of X-ray astronomers used lensed radio galaxies to identify and study distant galaxies with active supermassive black hole…

New research from NASA’s Jet Propulsion Laboratory suggests that the internal structure of a galaxy cluster is linked to the dark matter environment surrounding it….
Astronomers Detect Time Delays between Flaring Events in a Quasar
The Quintuple Quasar SDSSJ1029+2623 has been gravitationally imaged by an intervening cluster of galaxies. Astronomers have detected time delays between flaring events in the quasar,…
Chandra Views the “Cheshire Cat” Group of Galaxies
This new image from NASA’s Chandra X-ray Observatory shows the group of galaxies nicknamed the “Cheshire Cat.” X-rays from Chandra show that the two “eye”…
Hubble Reveals Some of the Earliest Known Galaxies
Using gravitational lensing, the Hubble Space Telescope has revealed some of the earliest known galaxies – galaxies that formed just 600 million years after the…
Hubble Finds Small Galaxy More Than 13 Billion Light-Years Away
Using the gravitational lensing power of galaxy cluster Abell 2744, Hubble has detected one of the farthest, faintest, and smallest galaxies ever seen. The small…
