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.

Many black holes found in nearby globular cluster

Researchers using the Hubble Space Telescope observed one of the closest globulars to Earth – NGC 6397 and were surprised to find signs of multiple stellar-mass black holes.

Strange Activity From a Newly Discovered Star

The star in question is called Swift J1818.0–1Th607 is what's known as a magnetar, though, none of the magnetars have ever been observed pulsing in quite the same way as Swift J1818.0–1607.

Milky Way's "Most Mysterious Star" Has a Companion

A mysteriously dimming star located about 1,480 light-years away in the constellation of Cygnus and known as Tabby's star is, in fact, a binary stellar system, made up of a F-type star and a smaller red dwarf star.

An Extra Strange Magnetar Discovered

Only 31 magnetars ( type of neutron star that has the strongest magnetic field ) have even been discovered and recently astronomers have found an extremely unique object that is both a magnetar and a pulsar.
