Where in powerful jets of distant active galaxies -- the mightiest and most energetic objects known -- are the violent outbursts of high energy gamma-ray emission produced?

The structures and star populations of massive galaxies appear to change as they age, but much about how these galaxies formed and evolved remains mysterious.

Magnetar Formation Mystery Solved?

Magnetars are the bizarre super-dense remnants of supernova explosions. They are the strongest magnets known in the Universe -- millions of times more powerful than the strongest magnets on Earth.

Odd Planet, So Far from Its Star

An international team led by Université de Montréal researchers has discovered and photographed a new planet 155 light-years from our solar system.

Using state of the art computer simulations, a team of French astrophysicists have for the first time explained a long standing mystery: why surges of star formation (so called 'starbursts') take place when galaxies collide.

Globular Clusters Rotate at Heart

Astronomers from the University of Texas at Austin and Germany's Max Planck Institute for Extraterrestrial Physics (MPE) recently found a surprise when studying some of the oldest star clusters in our galaxy.

Move over, Matrix - astronomers have done you one better. They have created the first realistic virtual universe using a computer simulation called "Illustris."

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.
