Hubble telescope ‘mother’ Nancy Grace Roman dies
The astronomy world is poorer off today. Nancy Grace Roman, the first chief of astronomy at NASA's Office of Space Science, died on December 25th at 93. She was widely considered the "mother" of the Hubble Space Telescope, persuading the scientific...
The Hubble Space Telescope has advanced our understanding of the universe immeasurably since it was first deployed to low Earth orbit in 1990. It's impossible to overemphasize just how valuable it has been to scientists. But now, the space-based obse...
Over the last couple of decades, we've spotted thousands of planets outside of our solar system -- Kepler alone has confirmed more than 2,600. But so far, we've haven't found any exomoons, despite the likelihood of them being prevalent in our galaxy....
Last October, researchers spotted a long, skinny object speeding through our solar system, and they initially pegged it as a comet from another solar system. But as they continued to observe the object, dubbed 'Oumuamua, its properties -- namely a la...
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...
Last month, astronomers running the Pan-STARRS 1 telescope in Hawaii spotted an intriguing object moving through our solar system and it became clear pretty quickly that the object, whether it was a comet or an asteroid, had come from outside of our...
Building the world's largest telescope has proven to be even more difficult than one might expect. The Thirty Meter Telescope, which has been planned for construction atop of Hawaii's Mauna Kea, has hit a number of snags, but it got a major approval...
Scientists say it's possible five Earth-sized planets orbiting Trappist-1, an ultra-cool dwarf star located 39 light years away, contain "significant amounts of water." An international team of astronomers used the Hubble Space Telescope (HST) to mea...
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...
