Estimated to be magnitude 5, the quake is the biggest ever detected on another planet. This adds to the catalog of more than 1,313 quakes InSight has detected since landing on Mars in 2018.
ESA's XMM-Newton has found a pulsar - the spinning remains of a once-massive star - that is a thousand times brighter than previously thought possible.
U.S. scientists have published a new research paper outlining the possibility that the universe could, relatively shortly, begin to shrink towards its demise and eventual rebirth.
More than three years after the release of the first-ever image of a black hole, scientists from the Event Horizon Telescope (EHT) shared an image of Sagittarius A* — the supermassive specimen sitting at the center of our own Milky Way galaxy.
Jupiter's moon Europa is a prime candidate in the search for life. The frozen moon has a subsurface ocean and the new research shows that the moon is pulling oxygen down below its icy shell.
In 2014, the Japanese Space Agency JAXA launched the Hayabusa 2 spacecraft to visit asteroid Ryugu. It arrived at the asteroid in June 2018 and studied it from orbit for over a year.
A critical stage of the James Webb Space Telescope's mirror alignment has been completed, keeping the state-of-the-art observatory on track to commence science observations in a few months.
Neutron stars are one possible suspect responsible for an abundance of positrons in the Milky Way. Now astronomers have caught one red handed.
Astronomers already knew Earth had one Trojan. Now we know it has two, with the second announced on February 1, 2022. This new Earth Trojan has been labeled 2020 XL5.
TESS reached a milestone. We now have over 5,000 exoplanet candidates. Scientists have a lot of work to do confirming them.
Just 4,000 light-years from Earth is a strange, star-sized object. It’s been observed by radio telescopes, but astronomers aren’t sure what it is. They call it a long period transient.
There was a huge weakness in our asteroid defense system when only one of the hemispheres was covered by telescopes that constantly scan the sky. Now NASA funded two more telescopes in the southern hemisphere.
Now, astronomers have officially found another elusive object that has long been theorized and that was first reported on back in 2009 but has never directly detected – a rogue black hole.
Astronomers completed a 40-hour long observation of an ultra-diffuse dwarf galaxy and discovered no traces of dark matter. Galaxies without hints of dark matter had been previously discovered though these remain rare anomalies.
Using telescopes from around the world, a team of astronomers recently discovered 70 additional free-floating planets (FFPs), the largest sample of “Rogue Planets” discovered to date in the Milky Way.
