For the first time, NASA and ESA's Hubble space telescope has captured a close-up image of a unique galaxy cluster considered to be the largest, hottest, and brightest ever discovered by astronom…
When a massive star expends its fuel, its core collapses into a dense object and sends the rest of its gas outward in an event called a supernova. What’s left is mostly neutron stars or black holes. …
So now it turns out, what we call the observable universe — the portion observable within our cosmological horizon, a.k.a the final frontier — has at least 10 times more galaxies than the mid-1990s…
It’s thought that dark matter makes up as much as a quarter of all matter in the universe , but we know very little about it because it has never been directly observed and it is exceedingly difficu…
Since 1990, the Hubble Space Telescope has been redefining how we view our Universe. From hundreds of miles above the surface of the Earth, it orbits the entire world every 97 minutes. Multiple servi…
Being unable to see the wood for the trees is a fairly common idiom, though we could just as easily say we can't see the Milky Way for the stars. Thanks to recent research based on an old astrono…
Astronomers have identified a weird pair of orbiting asteroids, called 288P, as the first known binary asteroid also classified as a comet. Astronomers recently spotted two space rocks behav…
“The Ganymede Ocean is believed to contain more water than Europa's,” says Olivier Witasse, a project scientist working on ESA’s future Jupiter Icy Moon Explorer (JUICE). “Six times more water in…
The Hubble Space Telescope has discovered something truly unique – a pair of orbiting asteroids that are behaving like a comet. A group of astronomers used the NASA/ESA telescope to observe the syste…
We go about our lives here on planet Earth — doing our jobs, cashing paychecks, and raising families — and most of the time we don’t question just how important we are. The jury is still out on wheth…
Bright clusters of galaxies --- seen as far back as ten billion light years in cosmic time --- appear to be aligned to their local surroundings on scales of millions of light years, an international …
NASA is called it the most interesting image ever taken by the Hubble Space Telescope—and the most comprehensive. It is one of the most remarkable. But the image—the amazing payoff of a new study c…
