Taking advantage of a cosmic "double lens," astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.
When a magnetar within the Milky Way galaxy belched out a flare of colossally powerful radio waves in 2020, scientists finally had concrete evidence to pin down an origin for fast radio bursts.
A strange star has revealed to astronomers a mysterious past - one that involves the merger of two ancient suns.
The discovery helps explain a long-running cosmic mystery about why some stars hurtle through space much faster than others.
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.
In recent years, astronomers have developed techniques to measure the metal content of stars with extreme accuracy.
It appears that sometimes stars fail to explode as supernovae and instead turn directly into black holes.
In August 2017, humanity observed a wonder. For the first time, we got to see two neutron stars colliding.
In the binary system 4U 1820-30, a neutron star is spinning so fast around its center axis that it completes a breathtaking 716 rotations per second.
Neutron stars with a penchant for extreme spinning could be churning out one of the most sought-after particles in the Universe.
In this system, called V404 Cygni, the black hole is consuming a small star that is spiraling in very close and fast while a newfound third star circles the black hole from much farther away.
One of the great mysteries of the Universe is where all the metal actually comes from.
TIC 290061484 is a system of gravitationally bound stars consisting of a tightly-orbiting binary pair with a third star that circles both. Astonishingly, they're so close together the entire system would fit inside the orbit of Mercury.
For the first time, astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface.
Terzan 5 star cluster is a copious producer of cosmic rays, because it contains a large population of rapidly rotating, incredibly dense and magnetised millisecond pulsars – which accelerate cosmic rays up to extremely high speeds.
