Astronomers Reveal Relationship Between the Color of a Galaxy and the Size of Its Bulge

April 22, 2014

0 Comments

Using data from the Sloan Digital Sky Survey to group together over half a million galaxies of all different colors, shapes, and masses, new research reveals a relatively simple relationship between the color of a galaxy and the size of its bulge – the more massive the bulge the redder the galaxy. The universe we […]

Researchers Reveal New Method for Studying Binary Star Systems

April 22, 2014

0 Comments

Using data from the Kepler spacecraft, researchers from the University of Washington confirm the first “self-lensing” binary star system. What looked at first like a sort of upside-down planet has instead revealed a new method for studying binary star systems, discovered by a University of Washington student astronomer. Working with UW astronomer Eric Agol, doctoral […]

Hubble Views Globular Cluster Messier 5

April 21, 2014

1 Comment

This newly released Hubble image shows globular cluster Messier 5, which is located 24,500 light-years away. This sparkling jumble is Messier 5 — a globular cluster consisting of hundreds of thousands of stars bound together by their collective gravity. But Messier 5 is no normal globular cluster. At 13 billion years old it is incredibly […]

Nearly completed, the VPHAS+ catalog will include stars and nebulae that are as much as 1500 times fainter than the ones in the older catalog, as well as much improved images of all objects. Atomic hydrogen is the lightest and by far most abundant element in the universe. When it is exposed to ultraviolet light, […]

New Technique Provides Near Real-Time Mapping of the Sun’s Interior

April 18, 2014

0 Comments

Using data from NASA’s Solar Dynamics Observatory, researchers have developed a new technique that opens the door for near real-time mapping of the sun’s roiling interior. Like a balloon bobbing along in the air while tied to a child’s hand, a tracer has been found in the sun’s atmosphere to help track the flow of […]

Kepler Discovers Earth-Size Planet Orbiting a Star in the ‘Habitable Zone’

April 18, 2014

0 Comments

Astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone,” confirming that Earth-size planets exist in the habitable zones of other stars and signaling a significant step closer to finding a world similar to Earth. Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in […]

Scientists Reveal Neutron Star Glitches Have a Minimum Size

April 17, 2014

0 Comments

New research reveals that sudden speed jumps in the rotational velocity of pulsars have a minimum size, and that they are caused not by the unpinning and displacement of just one sub-surface superfluid vortex, but by billions. A team of astronomers, including Danai Antonopoulou and Anna Watts from the Anton Pannekoek Institute of Astronomy (UvA), […]

New Modeling Reveals that Tilted Orbits Could Make More Worlds Habitable

April 16, 2014

7 Comments

New research from astrobiologists at NASA’s Goddard Space Flight Center reveals that large amplitude, high frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo feedback, increasing the outer edge of the habitable zone. Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according […]

Supercomputers Help Researchers Understand Black Holes

April 15, 2014

0 Comments

Using supercomputers like Stampede at the Texas Advanced Computing Center and Kraken at the National Institute for Computational Sciences, researchers try to predict and better understand the observational signatures of events like black holes devouring stars. Somewhere in the cosmos an ordinary galaxy spins, seemingly at slumber. Then all of a sudden, WHAM! A flash […]

Cassini Reveals Possible New Moon Forming Around Saturn

April 15, 2014

1 Comment

Using data from the Cassini spacecraft, astronomers believe they have discovered the possible formation of a new tiny moon within the rings of Saturn. NASA’s Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn. Informally named “Peggy,” the object may be a new moon. Details of the observations […]
