A tale of two pulsars' tails: Plumes offer geometry lessons to astronomers

Science Daily - Tue, 01/17/2017 - 1:57pm
Like cosmic lighthouses sweeping the universe with bursts of energy, pulsars have fascinated and baffled astronomers since they were first discovered 50 years ago. In two studies, international teams of astronomers suggest that recent images from NASA's Chandra X-ray Observatory of two pulsars -- Geminga and B0355+54 -- may help shine a light on the distinctive emission signatures of pulsars, as well as their often perplexing geometry.

The sun in detail: Contorted center of sunspot nearly twice the size of Earth

Science Daily - Tue, 01/17/2017 - 10:18am
New images have revealed otherwise invisible details of our Sun, including a new view of the dark, contorted center of a sunspot that is nearly twice the diameter of the Earth. The images are the first ever made of the Sun with a facility where ESO is a partner. The results are an important expansion of the range of observations that can be used to probe the physics of our nearest star.

Astrophysicists discover dimming of binary star

Science Daily - Mon, 01/16/2017 - 4:11pm
A team astrophysicists has observed the unexplained fading of an interacting binary star, one of the first discoveries using the Sarah L. Krizmanich Telescope.

Galaxy murder mystery

Science Daily - Mon, 01/16/2017 - 4:06pm
It’s the big astrophysical whodunnit. Across the Universe, galaxies are being killed and the question scientists want answered is, what’s killing them?

Presumed young star turns out to be a galactic senior citizen

Science Daily - Mon, 01/16/2017 - 9:20am
49 Lib, a relatively bright star in the southern sky, is twelve billion years old rather than just 2.3 billion. For many decades, researchers were stumped by conflicting data pertaining to this celestial body, because they had estimated it as much younger than it really is. Determining its age anew, astronomers have now successfully resolved all inconsistencies.

Hubble gazes into a black hole of puzzling lightness

Science Daily - Fri, 01/13/2017 - 3:54pm
The beautiful spiral galaxy visible in the center of the image is known as RX J1140.1+0307, a galaxy in the Virgo constellation imaged by the NASA/ESA Hubble Space Telescope, and it presents an interesting puzzle. At first glance, this galaxy appears to be a normal spiral galaxy, much like the Milky Way.

Understanding blended galaxies

Science Daily - Thu, 01/12/2017 - 2:33pm
Galaxies are merging all the time, even our own galaxy, the Milky Way. But how these mergers occur isn't entirely clear. An American astrophysicist will use a National Science Foundation grant to find and characterize supermassive black holes associated with merging galaxies.

Searching for planets in the Alpha Centauri system

Science Daily - Thu, 01/12/2017 - 1:07pm
Astronomers are conducting a search for planets in the nearby star system Alpha Centauri. Such planets could be the targets for an eventual launch of miniature space probes by the Breakthrough Starshot initiative.

Our galaxy's black hole is spewing out planet-size 'spitballs'

Science Daily - Wed, 01/11/2017 - 11:08am
Every few thousand years, an unlucky star wanders too close to the black hole at the center of the Milky Way. The black hole's powerful gravity rips the star apart, sending a long streamer of gas whipping outward. That would seem to be the end of the story, but it's not. New research shows that not only can the gas gather itself into planet-size objects, but those objects then are flung throughout the galaxy in a game of cosmic 'spitball.'

Farthest stars in Milky Way might be ripped from another galaxy

Science Daily - Wed, 01/11/2017 - 11:08am
The 11 farthest known stars in our galaxy are located about 300,000 light-years from Earth, well outside the Milky Way's spiral disk. New research shows that half of those stars might have been ripped from another galaxy: the Sagittarius dwarf. Moreover, they are members of a lengthy stream of stars extending one million light-years across space, or 10 times the width of our galaxy.

Struggle to escape distant galaxies creates giant halos of scattered photons

Science Daily - Wed, 01/11/2017 - 9:14am
Astronomers have discovered giant halos around early Milky Way type galaxies, made of photons (elementary particles of light) that have struggled to escape them.

Next-generation optics offer the widest real-time views of vast regions of the sun

Science Daily - Tue, 01/10/2017 - 4:10pm
A groundbreaking new optical device to correct images of the Sun distorted by multiple layers of atmospheric turbulence, is providing scientists with the most precisely detailed, real-time pictures to date of solar activity occurring across vast stretches of the star's surface.
