(PhysOrg.com) -- Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull. Without dark matter holding them together, our galaxy
"Congratulations LkCa 15! You've given birth to a proto-exoplanet!"
If there's one thing to be said for the Kepler mission, it's certainly turning up some very strange new worlds.
Humanity's most complex ground-based astronomy observatory, the Atacama Large Millimeter/submillimeter Array (ALMA), has officially opened for astronomers. The first released image, from a telescope still under construction, reveals a view of the Universe that cannot be seen at all by visible-light and infrared telescopes. Thousands of scientists from around the world have competed to be among the first few researchers to explore some of the darkest, coldest, furthest, and most hidden secrets of the cosmos with this new astronomical tool.

The Bolshoi supercomputer simulation, announced Thursday, is the most accurate and detailed large cosmological simulation run to date, giving physicists and
The "fifth planet" is a hypothesized giant world that was flung out of our solar system 4 billion years ago.
It currently takes 90 minutes to transmit high-resolution images from Mars, but NASA would like to dramatically reduce that time to just minutes. A new optical communications system that NASA plans to demonstrate in 2016 will lead the way and even allow the streaming of high-definition video from distances beyond the Moon.
(PhysOrg.com) -- “We know that about 25% of the matter in the universe is dark matter, but we don’t know what it is,” Michael Kesden tells PhysOrg.com. “There are a number of different theories about what dark matter could be, but we think one alternative might be very small primordial black holes.”
To soar far away from Earth and even beyond the moon, NASA has dreamed up the world
Discovery News digs deep into our world's mysteries. Join us to explore current events and uncover the science behind the headlines. We Dig. You Discover.
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?
The largest digital camera ever built for a space mission has been painstakingly mosaicked together from 106 separate electronic detectors. The resulting "billion-pixel array" will serve as the super-sensitive
(PhysOrg.com) -- A small robotic surveyor arrives to explore a near-Earth asteroid. Another robotic spacecraft is returning to Earth with a pristine comet surface sample. Meanwhile, a robotic explorer is approaching Uranus, carrying scientific instruments that will allow us to learn more about our solar system. What do all these mission concepts have in common?
