Astronomers find the remains of the Universe's first stars

For the first time ever, we were able to identify the chemical traces of the explosions of the first stars in very distant gas clouds.

Scientists map gusty winds in a far-off neutron star system

An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star as it pulls in material from a nearby star. As the disk spins, it whips up powerful winds that can affect the surroundings of black holes.

Brightest gamma-ray burst ever observed

Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.

Scientists discover the origin of water in our solar system

New findings suggest the water originates from the space between solar systems, billions of years before the birth of our sun.

Hubble finds that ghost light among galaxies stretches far back in time

In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster.

Two Stars Colliding Like We've Never Seen Before

The aftermath of an epic collision involving at least one neutron star has been captured for the first time in the millimeter range of radio frequency wavelengths.

Astronomers Have Spotted A Record-Breaking Magnetic Field in Space

Far out in the Milky Way, roughly 22,000 light years from Earth, a star unlike any other roars with a magnetic force that beats anything physicists have ever seen. 

Unusual Pulsar Detected

The discovery of a neutron star emitting unusual radio signals is rewriting our understanding of these unique star systems.

Astronomers See X-ray 'ball Of Fire' Of A Stellar Nova For The First Time

The eROSITA telescope aboard the Spektr-RG space observatory at the L2 Lagrange point captured the first time in what is known as the ‘fireball’ phase of a classical nova. 

The brightest, furthest pulsar in the Universe

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.

Pulsar found leaking antimatter

Neutron stars are one possible suspect responsible for an abundance of positrons in the Milky Way. Now astronomers have caught one red handed.

Astronomers Discover a Star That Flashes Every 20 Minutes

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.

Nature of fast radio bursts clarified

By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind  fast radio bursts after all. The bursts may come from a highly magnetized, isolated neutron star - magnetar. 

Blinking Star Found Near the Center of the Milky Way

International team of astronomers found a star 100 times larger than our sun that nearly disappears from the sky every few decades.  They also have no idea why it does so. This could be a new class of stars.

Sextuple star system fascinates with three eclipsing binaries

Astronomers studying data from NASA’s TESS mission have found a remarkable sextuple star system featuring three gravitationally bound eclipsing binaries.
