A University of Utah-led team discovered a "hypervelocity star" that is the closest, second-brightest and among the largest of 20 found so far. Speeding at more than 1 million miles per hour (mph), the star may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious "dark matter" surrounding the galaxy, astronomers say.

Bright Galaxy Centaurus A

Centaurus A is the fifth brightest galaxy in the sky -- making it an ideal target for amateur astronomers -- and is famous for the dust lane across its middle and a giant jet blasting away from the supermassive black hole at its center. Cen A is an active galaxy about 12 million light years from Earth.

The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour.

For the first time an international team of astronomers has measured circular polarization in the bright flash of light from a dying star collapsing to a black hole, giving insight into an event that happened almost 11 billion years ago.

The majority of the stars in our Galaxy, the Milky Way, reside in a single huge disc, known as the Galactic Plane, spanning 100 000 light-years across. The Sun also resides in this crowded stellar hub, lying roughly halfway between its centre and its outer edges.

Long before the term "citizen science" was coined, the field of astronomy has benefited from countless men and women who study the sky in their spare time.

Somewhere out in the cosmos an ordinary galaxy spins, seemingly at slumber. Then all of a sudden, WHAM! A flash of light explodes from the galaxy's center.

Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away -- 10 times farther than previously possible.

Astronomers using ESO's Very Large Telescope in Chile have captured this eye-catching image of planetary nebula PN A66 33 -- usually known as Abell 33.

Hubble Peers at the Heart of NGC 5793

This new Hubble image is centered on NGC 5793, a spiral galaxy over 150 million light-years away in the constellation of Libra.

Touring the Milky Way now is as easy as clicking a button with NASA's new zoomable, 360-degree mosaic presented Thursday at the TEDActive 2014 Conference in Vancouver, Canada.

NIST Chips Help BICEP2 Telescope

The view back in time--way back to the origins of the universe--just got clearer. Much clearer.

New View of Supernova Death Throes

A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible.

After searching hundreds of millions of objects across our sky, NASA's Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed "Planet X."

Astronomers have used NASA's Chandra X-ray Observatory and the European Space Agency's (ESA's) XMM-Newton to show a supermassive black hole six billion light years from Earth is spinning extremely rapidly.

First Light for MUSE

Following testing and preliminary acceptance in Europe in September 2013, MUSE was shipped to ESO's Paranal Observatory in Chile.

Spiral Galaxy Spills Blood and Guts

This new Hubble image shows spiral galaxy ESO 137-001, framed against a bright background as it moves through the heart of galaxy cluster Abell 3627.

How Small Cosmic Seeds Grow Into Big Stars

New images from the Smithsonian's Submillimeter Array (SMA) telescope provide the most detailed view yet of stellar nurseries within the Snake nebula. These images offer new insights into how cosmic seeds can grow into massive stars.

Using a telescope installed at the driest place on Earth -- Ridge A in Antarctica -- a UNSW-led team of researchers has identified a giant gas cloud which appears to be in an early stage of formation.

The 64th and final foundation for the MeerKAT telescope antenna was poured yesterday (Tuesday, February 11th, 2014) at South Africa's SKA site in the Karoo.
