Magnetar 3XMM J185246.6+003317

Massive stars end their life with a bang, exploding as supernovas and releasing massive amounts of energy and matter. What remains of the star is a small and extremely dense remnant: a neutron star or a black hole.

Why Sibling Stars Look Alike

Why Sibling Stars Look Alike

The chemical uniformity of stars in the same cluster is the result of turbulent mixing in the clouds of gas where star formation occurs, according to a study by astrophysicists at the University of California, Santa Cruz.

View the red star Antares near the red planet Mars, plus the Zodiacal Light that points towards Jupiter in the morning sky.


Telescopes Uncover Early Construction of Giant Galaxy

Telescopes Uncover Early Construction of Giant Galaxy

Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed "Sparky," is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate.


Pebble-size Particles May Jump-Start Planet Formation

Pebble-size Particles May Jump-Start Planet Formation

Rocky planets like Earth start out as microscopic bits of dust tinier than a grain of sand, or so theories predict.


Eta Carinae - Our Neighboring Superstars

Eta Carinae - Our Neighboring Superstars

The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the Sun, it is also extremely volatile and is expected to have at least one supernova explosion in the future.


Hubble Views Distant Merging Galaxies

Hubble Views Distant Merging Galaxies

Using the NASA/ESA Hubble Space Telescope and many other telescopes on the ground and in space, an international team of astronomers has obtained the best view yet of a collision that took place between two galaxies when the universe was only half its current age.


Supernova Seen In Two Lights

Supernova Seen In Two Lights

The destructive results of a mighty supernova explosion reveal themselves in a delicate blend of infrared and X-ray light, as seen in this image from NASA's Spitzer Space Telescope and Chandra X-Ray Observatory, and the European Space Agency's XMM-Newton.

NASA's Rossi X-ray Timing Explorer Satellite Catches the Beat of a Midsize Black Hole Video in Story

Astronomers from the University of Maryland, College Park (UMCP) and NASA's Goddard Space Flight Center have uncovered rhythmic pulsations from a rare breed of black hole in archival data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite.


Second Season Underway for Dark Energy Survey to Catalog the Wonders of Deep Space

Second Season Underway for Dark Energy Survey to Catalog the Wonders of Deep Space

On August 15, with its successful first season behind it, the Dark Energy Survey (DES) collaboration began its second year of mapping the southern sky in unprecedented detail.

RXTE Satellite Catches the Beat of a Midsize Black Hole Video in Story

Astronomers have uncovered rhythmic pulsations from a rare type of black hole 12 million light-years away by sifting through archival data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite.


Hubble Revisits a Globular Cluster's Age

Hubble Revisits a Globular Cluster's Age

Globular clusters are big balls of old stars that orbit around their host galaxy. It has long been believed that all the stars within a globular cluster form at the about same time, a property which can be used to determine the cluster's age.


Supernova SN 2014J Explodes

Supernova SN 2014J Explodes

New data from NASA's Chandra X-ray Observatory has provided stringent constraints on the environment around one of the closest supernovas discovered in decades.
