Super-Jupiter Circles a Massive Star

Astrophysicists at the University of Toronto and other institutions across the United States, Europe and Asia have discovered a 'super-Jupiter' around the massive star Kappa Andromedae

Kepler Completes Begins Extended Mission

NASA is marking two milestones in the search for planets like Earth -- the successful completion of the Kepler Space Telescope's 3 1/2- year prime mission and the beginning of an extended mission that could last as long as four years.

Astronomers have found evidence for a dying Sun-like star coming briefly back to life after casting its gassy shells out into space, mimicking the possible fate our own Solar System faces in a few billion years.

Rogue Planet Spotted?

Astronomers using ESO's Very Large Telescope and the Canada-France-Hawaii Telescope have identified a body that is very probably a planet wandering through space without a parent star.

Life and Death in a Star-forming Cloud

The aftershock of a stellar explosion rippling through space is captured in this new view of supernova remnant W44, which combines far-infrared and X-ray data from ESA's Herschel and XMM-Newton space observatories.

BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the universe.

The sole secondary mirror and another primary mirror that will fly aboard NASA's James Webb Space Telescope arrived at NASA's Goddard Space Flight Center in Greenbelt, Md., on Nov. 5, 2012.

A new super-Earth planet that may have an Earth-like climate and be just right to support life has been discovered around a nearby star by an international team of astronomers, led by Mikko Tuomi, University of Hertfordshire, and Guillem Anglada-Escude, University of Goettingen.

A Ghost in Cepheus

Described as a "dusty curtain" or "ghostly apparition," mysterious reflection nebula VdB 152 really is very faint. Far from your neighborhood on this Halloween Night, the cosmic phantom is nearly 1,400 light-years away.

Stars are born in hiding, when dense regions within clouds of gas and dust collapse under their own gravity. But the clouds not only provide the raw material for star formation, they also absorb most of the light from their interior, hiding from view the crucial details of stellar birth -- one of the key astronomical processes if we want to understand our own origins!

Galactic Thief Almost Got Away with It

One of the closest galaxies to the Milky Way almost got away with theft. However, new simulations convicted the Large Magellanic Cloud (LMC) of stealing stars from its neighbor, the Small Magellanic Cloud (SMC). And the crucial evidence came from surveys looking for something entirely different -- dark objects on the outskirts of the Milky Way.

Using a brand-new radio telescope, astronomers have produced one of the best images ever made at the lowest frequencies of giant bubbles produced by a super-massive black hole.

Hubble astronomers have looked at one of the most distant and brightest quasars in the universe and are surprised by what they did not see: the underlying host galaxy of stars feeding the quasar.

Astronomers using NASA's Hubble Space Telescope have obtained a remarkable new view of a whopper of an elliptical galaxy that may have been puffed up by the actions of one or more black holes in its core.

Dark Matter Halos May Contain Stars

Could it be that dark matter "halos" -- the huge, invisible cocoons of mass that envelop entire galaxies and account for most of the matter in the universe -- aren't completely dark after all but contain a small number of stars?

Scientists at the University of Arizona and in California have completed the most challenging large astronomical mirror ever made.

The Color of an Exoplanet

The search for extrasolar planets has already detected rocky planets and interesting planetary candidates in the Habitable Zone of their host stars. Astrobiologists are pioneering new ways of imaging and examining these worlds, including how to assess their habitability.

Elliptical Galaxy Holds a Hidden Spiral

Most big galaxies fit into one of two camps: pinwheel-shaped spiral galaxies and blobby elliptical galaxies. Spirals like the Milky Way are hip and happening places, with plenty of gas and dust to birth new stars.

CHEOPS Will Study Super-Earths

Studying planets around other stars will be the focus of the new Small-class Science Programme mission, Cheops, ESA announced today. Its launch is expected in 2017.

European astronomers have discovered a planet with about the mass of the Earth orbiting a star in the Alpha Centauri system -- the nearest to Earth. It is also the lightest exoplanet ever discovered around a star like the Sun. The planet was detected using the HARPS instrument on the 3.6-meter telescope at ESO's La Silla Observatory in Chile. The results will appear online in the journal Nature on 17 October 2012.
