With the help of a magnifying glass 4 million lightyears wide, astronomers may have solved the riddle of what burned away the hydrogen fog that pervaded the early universe.
Projects under NASA’s CLPS program – including the Odysseus lander that made it to the lunar surface – will probe unexplored questions about the universe’s formation.
The universe is expanding faster than physicists would expect. To figure out what processes underlie this fast expansion rate, some researchers are first trying to rule out what processes can’t.
Bright, flickering galaxies called quasars were thought to pose a problem for our understanding of the cosmos – but new research shows Einstein was right yet again.
Different measures of the rate of the Universe’s expansion give different results – and a new measurement technique only makes matters more complicated.
For decades physicists have argued over the nature of the elusive dark matter that pervades the Universe. A clever new study uses gravitational lensing to bring new evidence to the debate.
Astronomers have detected a radio glow caused by shockwaves in the gigantic filaments between galaxy clusters in the ‘cosmic web’ which pervades the Universe.
While we can’t see inside a black hole, we can spot the intensely bright glowing disc that surrounds one. Now, we might better understand why these discs appear to ‘twinkle’.
