How to Escape From a Black Hole

An obese oddball of a star has left astronomers wondering how it could have formed. Found with the Arecibo radio telescope in Puerto Rico, the star is a pulsar – a compact, rapidly spinning star – called J1903+0327. It lies 20,000 light-years away spinning at a rate of 465 revolutions per second – the fifth fastest-spinning pulsar known in our Galaxy.

Venus Express has detected the molecule hydroxyl on another planet for the first time. This detection gives scientists an important new tool to unlock the workings of Venus’s dense atmosphere.

Physicists at Penn State have provided a mechanism by which information can be recovered from black holes, those regions of space where gravity is so strong that, according to Einstein's theory of general relativity, not even light can escape. The team's findings pave the way toward ending a decades-long debate sparked by renowned physicist Steven Hawking.

The most recent supernova in our galaxy has been discovered by tracking the rapid expansion of its remains. The supernova explosion occurred about 140 years ago, making it the most recent in the Milky Way. Previously, the last known supernova in our galaxy occurred around 1680, an estimate based on the expansion of its remnant, Cassiopeia A.

NASA's Gamma-ray Large Area Space Telescope, or GLAST, is receiving finishing touches at the Cape Canaveral Air Force Station, near the beaches of eastern central Florida for its launch. The spacecraft is set for launch aboard a Delta II rocket no earlier than June 3. The launch window runs from 11:45 a.m. to 1:40 p.m. EDT.

Ever since Copernicus placed the Sun at the center of the universe instead of the Earth, scientific discoveries have been repeatedly making our home planet less special and more ordinary. But could the "principle of mediocrity" turn out to be wrong in one critical recent discovery--dark energy--and could that discovery really mean something other than what physicists have suggested?

When NASA's Phoenix Mars Lander descends to the surface of the Red Planet on May 25, few will be watching as closely as the men and women who have spent years planning, analyzing and conducting tests to prepare for the dramatic and nerve-wracking event known as EDL - Entry, Descent and Landing. For after all their hard work, they know that landing on Mars is not a walk in the park. Less than 50 percent of all previous lander missions have made it safely to the surface.

New research on the Antennae Galaxies using the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope shows that this benchmark pair of interacting galaxies is in fact much closer than previously thought - 45 million light-years instead of 65 million light-years.

The futuristic epic 2001: A Space Odyssey influenced many to fall in love with the limitless possibilities of space exploration. The movie sparked imaginations and provided a realistic preview of what our future in space might look like.
