It’s one of the big cosmology debates: the universe is expanding, but how fast exactly? Two available measurements yield different results. Leiden physicist David Harvey…
Astronomers at the University of Canterbury (UC) have found an incredibly rare new Super-Earth planet towards the center of the galaxy. The planet is one…
The NASA/ESA Hubble Space Telescope doesn’t usually get much assistance from its celestial subjects — but to take this image, the telescope opted for teamwork…
Gravity is so much a part of our daily lives that it is all too easy to forget its awesome power — but on a…
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…
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…
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…
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…
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…
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 uses the power of gravitational lensing to get a better look at galaxy cluster Abell 370 and its several hundred galaxies that are tied…
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…
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…
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….
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,…
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”…
Using gravitational lensing, the Hubble Space Telescope has revealed some of the earliest known galaxies – galaxies that formed just 600 million years after the…
