Unraveling a butterfly's aerial antics could help builders of bug-size flying robots

Posted: 02 Feb 2012 12:16 PM PST

By figuring out how butterflies flutter among flowers with amazing grace and agility, researchers hope to help build small airborne robots that can mimic those maneuvers.

Stellar astrophysics: The discovery of deceleration

Posted: 02 Feb 2012 12:14 PM PST

Pulsars are among the most exotic celestial bodies known. They have diameters of about 20 kilometres, but at the same time roughly the mass of our sun. A sugar-cube sized piece of its ultra-compact matter on Earth would weigh hundreds of millions of tons. A sub-class of them, known as millisecond pulsars, spin up to several hundred times per second around their own axes. Previous studies reached the paradoxical conclusion that some millisecond pulsars are older than the universe itself.

New super-Earth detected within the habitable zone of a nearby cool star

Posted: 02 Feb 2012 12:14 PM PST

Sientists have discovered a potentially habitable super-Earth orbiting a nearby star. The star is a member of a triple star system and has a different makeup than our Sun, being relatively lacking in metallic elements. This discovery demonstrates that habitable planets could form in a greater variety of environments than previously believed.

Hubble zooms in on a magnified galaxy

Posted: 02 Feb 2012 12:08 PM PST

Astronomers aimed Hubble at one of the most striking examples of gravitational lensing, a nearly 90-degree arc of light in the galaxy cluster RCS2 032727-132623. Hubble's view of the distant background galaxy, which lies nearly 10 billion light-years away, is significantly more detailed than could ever be achieved without the help of the gravitational lens.

Do black holes help stars form?

Posted: 02 Feb 2012 06:43 AM PST

The center of just about every galaxy is thought to host a black hole, some with masses of thousands of millions of Suns and consequently strong gravitational pulls that disrupt material around them. They had been thought to hinder the birth of stars, but now astronomers studying the nearby galaxy Centaurus A have found quite the opposite: a black hole that seems to be helping stars to form.

Breakthrough in understanding ultrafast magnetism
