Light does not always travel in straight lines. As Einstein predicted in his Theory of General Relativity, massive objects will deform the fabric of space…
The dozens of newly identified gravitational lenses could also reveal ancient galaxies. Earlier this year, a machine learning algorithm detected up to 5,000 possible gravitational…
Could one of the biggest puzzles in astrophysics be solved by reworking Albert Einstein’s theory of gravity? Not yet, according to a new study co-authored…
What Is Gravitational Lensing? Gravitational lensing occurs when a massive celestial body — such as a galaxy cluster — causes a sufficient curvature of spacetime…
By taking advantage of a natural lens in space, astronomers have captured an unprecedented look at X-rays from a black hole system in the early…
Astronomers have used an “X-ray magnifying glass” to study a black hole system in the early Universe. The amplification and magnification of light by an…
Machine learning key to discovery of over 1200 gravitational lenses. Data from the DESI (Dark Energy Spectroscopic Instrument) Legacy Imaging Surveys have revealed over 1200…
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…
