Scientists validate theory of relativity on galactic level
Einstein's theory of general relativity is rather important when it's crucial to the modern understandings of the universe and technology like satellites. But does it hold up with something as vast as a galaxy? Thanks to researchers, we know the an...
Astronomers have spotted numerous extremely distant galaxies, but spotting individual stars is understandably much more difficult unless they go supernova. Sometimes, though, cosmic alignment works in their favor. Researchers using Hubble space tel...
Gravitational lensing is when the image of a distant object in space -- like a galaxy, for example -- is distorted and multiplied by the gravity of a massive object, such as a galaxy cluster, lying in front of the smaller, faraway object. It's a usef...
Scientists at the Instituto de Astrofisica de Canarias, a research institute in the Canary Islands, just discovered one of the brightest galaxies we've ever come across. It's around a thousand times brighter than our galaxy, has a very high rate of s...
At the rate things are going, astronomers may have to toss out the rule book for galaxy formation. Researchers using the Hubble Space Telescope have discovered an ancient galaxy (formed 2.7 billion years after the Big Bang) with two dozen star nurser...
With the help of NASA's Hubble Space Telescope, researchers made a surprising discovery that goes against what we thought we knew about old galaxies and how they evolve. Our galaxy, the Milky Way, is a disk-shaped spiral galaxy. Typical of this shape...
As NASA astronomers peer further and further into space, they require ever larger and more powerful telescopes to do so. That's why one team of researchers from the Jet Propulsion Lab have proposed using the biggest object in our solar system, the Su...
Scientists have only just started finding extremely faint galaxies. However, they've already topped themselves by discovering the faintest known galaxy to date... and it might just provide insight into the universe's early days. Found through gravita...
NASA is kicking off a search for free-spirited exoplanets as part of the Kepler space telescope's extended K2 mission. It's an impressive quest for an instrument that was all but written off several years ago because of damage to its control wheels....
