This extremely powerful and young galaxy was magnified, like a lens, by a foreground galaxy
Watching distant galaxies has revealed the elusive nature of dark energy
Using Einstein’s general theory of relativity and highly sensitive equipment, astronomers have constrained the role of dark energy in the early universe
Hubble looks at the universe’s earliest galaxies
The first set of observations for the BUFFALO survey began with the galaxy cluster Abell 370
Scientists successfully test Einstein’s general relativity outside the Milky Way
By comparing the mass of ESO 325-G004 with the curvature of space around it, the astronomers found that gravity on these astronomical length-scales behaves as predicted by general relativity
Hubble spots the farthest star ever seen
This massive blue star existed just 4.4 billion years after the Big Bang
‘Wobbling’ galaxies upset our understanding of dark matter
This unusual phenomenon within galaxy clusters may indicate to a new physics at work
Artificial Intelligence used to discover gravitational lens events
Bringing artificial intelligence into astronomy will quicken the painstaking process of searching through piles of observations
New confirmation of Einstein’s general theory of relativity
Einstein predicted gravitational lensing over one hundred years ago
Large numbers of dwarf galaxies discovered in the early universe
The tiny structures could reveal important details about a productive period of star formation in the cosmos billions of years ago
