Elliptical galaxy NGC 1132 As Seen By Chandra

Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found.

Comet 67P/Churyumov-Gerasimenko As Seen 45 Years Ago

Comet 67P/Churyumov-Gerasimenko As Seen 45 Years Ago

It was 45 years ago when astronomer Klim Churyumov and Svetlana Gerasimenko, one of his researchers, unwittingly began a new chapter in the history of space exploration.


Hubble Finds Extremely Distant Galaxy through Cosmic Magnifying Glass

Hubble Finds Extremely Distant Galaxy through Cosmic Magnifying Glass

Peering through a giant cosmic magnifying glass, NASA's Hubble Space Telescope has spotted a tiny, faint galaxy -- one of the farthest galaxies ever seen. The diminutive object is estimated to be more than 13 billion light-years away.


The Milky Way Ransacks Nearby Dwarf Galaxies of Their Gas

The Milky Way Ransacks Nearby Dwarf Galaxies of Their Gas

Astronomers using the National Science Foundation's Green Bank Telescope (GBT) in West Virginia, along with data from other large radio telescopes, have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame.

Curious Signal Hints at Dark Matter - First Evidence of Axions?

Space scientists at the University of Leicester have detected a curious signal in the X-ray sky -- one that provides a tantalizing insight into the nature of mysterious 'dark matter.'


First Evidence of a Hydrogen-Deficient Supernova Progenitor

First Evidence of a Hydrogen-Deficient Supernova Progenitor

A group of researchers led by Melina Bersten of Kavli IPMU recently presented a model that provides the first characterization of the progenitor for a hydrogen-deficient supernova.


APEX Reveals Hidden Star Formation in Protocluster

APEX Reveals Hidden Star Formation in Protocluster

Galaxy clusters are the largest objects in the Universe held together by gravity but their formation is not well understood.


Hubble Catches a Dusty Spiral in Virgo

Hubble Catches a Dusty Spiral in Virgo

This magnificent new image taken with the NASA/ESA Hubble Space Telescope shows the edge-on spiral galaxy NGC 4206, located about 70 million light-years away from Earth in the constellation of Virgo.


Hungry Black Hole Eats Faster Than Thought Possible

Hungry Black Hole Eats Faster Than Thought Possible

Astronomers have discovered a black hole that is consuming gas from a nearby star 10 times faster than previously thought possible.


NuSTAR Telescope Discovers Shockingly Bright Dead Star

NuSTAR Telescope Discovers Shockingly Bright Dead Star

Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar - a dense stellar remnant left over from a supernova explosion - ever recorded.


Swift Observes Mega Flares from a Mini Star

Swift Observes Mega Flares from a Mini Star Video in Story

On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions was as much as 10,000 times more powerful than the largest solar flare ever recorded.


Simulations Reveal An Unusual Death for Ancient Stars

Simulations Reveal An Unusual Death for Ancient Stars

Certain primordial stars--those between 55,000 and 56,000 times the mass of our Sun, or solar masses--may have died unusually. In death, these objects--among the Universe's first-generation of stars--would have exploded as supernovae and burned completely, leaving no remnant black hole behind.


A Young Galaxy in the Local Universe?

A Young Galaxy in the Local Universe?

Astronomers usually have to peer very far into the distance to see back in time and view the universe as it was when it was young.

NASA Prepares for Planetary Science Balloon Mission

The Balloon Observation Platform for Planetary Science (BOPPS) is a high-altitude, stratospheric balloon mission that is planned for launch today to study a number of objects in our solar system, including an Oort cloud comet.


Most Stars are Born in Clusters, Some Leave Home

Most Stars are Born in Clusters, Some Leave Home

New modeling studies from Carnegie's Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up.

Infant Solar System Shows Signs of Windy Weather

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed what may be the first-ever signs of windy weather around a T Tauri star, an infant analog of our own Sun.
