Could our universe be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe?
A new ground-based instrument will help astronomers using NASA
Sierra Nevada Corporation's (SNC) proposed Dream Chaser vehicle. It looks like a spacecraft ought to look. This is one of the key US commercial human spaceflight projects now in development.
A new era of utilization for research and technology begins for the completed International Space Station. The orbiting laboratory shifts focus in 2011 from finalizing construction efforts to full-scale use of the facility for scientific investigation and technological advances.
Astronomers using ESO’s world-leading exoplanet hunter HARPS have today announced a rich haul of more than 50 new exoplanets, including 16 super-Earths, one of which orbits at the edge of the habitable zone of its star. By studying the properties of all the HARPS planets found so far, the team has found that about 40% of stars similar to the Sun have at least one planet lighter than Saturn.
(PhysOrg.com) -- In the never ending search for proof that dark matter really exists, new findings have emerged from a team working under a big mountain in Italy. The group, from the Max Planck Institute in Germany, have pre-published a paper on arXiv, and have also given a talk at the Topics in Astroparticle and Underground Physics conference in Munich where they describe how their CRESST II detector has recorded 67 events which they say cannot be explained by anything other than Weakly Interacting Massive Particles (WIMPS), a type of dark matter.
Usually, running five minutes late is a bad thing since you might lose your dinner reservation or miss out on tickets to the latest show. But when a planet runs five minutes late, astronomers get excited because it suggests that another world is nearby.

Astronomers have made an important breakthrough in the understanding of how pulsars work. Using a new inverse mapping or reverse engineering approach, researchers were able to establish for the first time that most of the light from the pulsar comes from close to the star
A team of European astronomers has used ESO’s Very Large Telescope (VLT) to track down a star in the Milky Way that many thought was impossible. They discovered that this star is composed almost entirely of hydrogen and helium, with only remarkably small amounts of other chemical elements in it. This intriguing composition places it in the “forbidden zone” of a widely accepted theory of star formation, meaning that it should never have come into existence in the first place. The results will appear in the 1 September 2011 issue of the journal Nature.
After nine months of number-crunching on a powerful supercomputer, a beautiful spiral galaxy matching our own Milky Way has emerged from a computer
A green thumb and a little flair as a gourmet chef may be among the key skills for the first men and women who travel to the Red Planet later this century, according to one scientist.
A galaxy with a combination of characteristics never seen before is giving astronomers a tantalizing peek at processes they believe played key roles in the growth of galaxies and clusters of galaxies early in the history of the Universe. The galaxy, dubbed Speca by the team of researchers, is only the second spiral, as opposed to elliptical, galaxy known to produce large, powerful jets of subatomic particles moving at nearly the speed of light. It also is one of only two galaxies to show that such activity occurred in three separate episodes.
A supernova discovered Wednesday is closer to Earth -- approximately 21 million light years away -- than any other of its kind in a generation. Astronomers believe they caught the supernova within hours of its explosion -- a rare feat for events of this type.
