NASA's Curiosity Mars rover viewed these yellow crystals of elemental sulfur using its Mast Camera. The discovery marks the first time this mineral has ever been found in a pure form on Mars.
Measurements over the years show that the planet's upper atmosphere is cooling and that the temperature has halved. None of the other planets experienced the same changes.
For the first time, we have succeeded in taking a zoomed-in image of a dying star in a galaxy outside our own Milky Way. The star WOH G64 is located a staggering 160 000 light-years from us.
According to a new analysis of the Lafayette Meteorite, minerals within it formed in the presence of water 742 million years ago. It's a real breakthrough in the dating of aqueous minerals on Mars.
In recent years, astronomers have developed techniques to measure the metal content of stars with extreme accuracy.
Using data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have completed the most precise gravity test ever taken.
New findings using data from NASA's IXPE mission offer unprecedented insight into the shape and nature of a structure important to black holes called a corona.
Astrobiologist Dirk Schulze-Makuch believes that humans may have unintentionally killed life on Mars in the 1970s.
An international team has discovered a new multi-planet system around a sun-like star, including an ultra-short period planet with one of the highest densities ever measured.
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered three ultra-massive galaxies -- nearly as massive as our own Milky Way Galaxy - already in place within the first billion years after the Big Bang.
The chances of intelligent life emerging in our Universe - and in any hypothetical ones beyond it - can be estimated by a new theoretical model which has echoes of the famous Drake Equation.
In March 2021, astronomers observed a high-energy burst of light from a distant galaxy. Assigned the name AT 2021hdr, it was thought to be a supernova.
For decades, we've thought we had a pretty good grasp of Uranus. The penultimate planet, our best measurements suggest, has a whole slew of idiosyncrasies. And one of the most puzzling is its magnetic field.
A team of astronomers believe that our planet’s gravitational pull could alter the surface of Apophis, a near-Earth asteroid (NEA) set to make a close approach to Earth in five years’ time.
It appears that sometimes stars fail to explode as supernovae and instead turn directly into black holes.
