NASA seeks to understand vision changes due to microgravity

By - March 6, 2015 2 Pictures
Having evolved under the pressure of Earth's gravity, it isn't surprising that our bodies experience adverse physiological affects after long periods in low-Earth orbit. NASA hopes that a new experiment, the Fluid Shifts investigation, set to launch to the ISS later this year, will shed light on the causes of vision loss and deformation of the structure to the eye often suffered by astronauts over the course of a stay aboard the ISS.

Astronomers see supernova explosion using galaxies as lenses

By - March 6, 2015 7 Pictures
A team of astronomers led by the Australian National University (ANU) has discovered a lens of galactic proportions. Using the Hubble Space Telescope and the Keck Observatory in Hawaii, the scientists saw a supernova not once, but four times by using the gravity of a distant cluster of galaxies to act as a natural lens that magnified and quadrupled the image of the exploding star.

LISA Pathfinder gravity probe moves to testing

By - March 4, 2015 3 Pictures
A European Space Agency (ESA) mission aimed at testing new technologies for understanding the universe has left Britain for final testing before being launched into space. The LISA Pathfinder mission's propulsion and science modules left Airbus Defence and Space for Industrie Anlagen Betriebs Gesellschaft (IABG) in Germany for final tests before shipment to the ESA launch site in Kourou, French Guiana, where they will be shot into low-Earth orbit atop a Vega rocket.

Research suggests dark matter plays a significant role in our planet's mass extinction cycle

By - February 24, 2015 1 Picture
A new study carried out by Professor Michael Rampino of New York University suggests that dark matter may have had a part to play in the periodic mass extinction events that are known to have taken place throughout Earth's history. It takes our planet roughly 250 million years to circle the Milky Way, and around every 30 million years the Sun's orbit takes us through what is known as the galactic disk. The galactic disk is where the majority of the mass in our galaxy resides, and alongside it a thin disk of dark matter. Read More

New Planck map begins to unlock the secrets of the early universe

By - February 13, 2015 2 Pictures
ESA's Planck mission is yielding some surprising findings along with a beautiful new map of the Milky Way that breaks down some of the key elements of our galaxy. The telescope spent four years studying the cosmic microwave background radiation (CMB), a relic from the birth of the universe. The resulting data from this endeavor is now helping us refine how we measure matter, how we understand dark matter and generally just unraveling the secrets of the universe. Read More

Why didn't the universe collapse after the Big Bang? It's a question of gravity

By - November 19, 2014 1 Picture
Not only does gravity keep us safely on the ground and hold the planets in alignment, but now it may soon get the credit for saving the whole universe. Physicists at the Imperial College London and the Universities of Copenhagen and Helsinki believe that the interaction between Higgs boson particles and gravity had a stabilizing effect on the very early universe, thereby preventing the Big Crunch – a catastrophic collapse into nothing – from occurring shortly after the Big Bang.

New map shows world's seafloor in unprecedented detail

By - October 3, 2014 8 Pictures
Given they aren't covered by oceans, it's maybe not so surprising that we know more about the topography of the Moon and Mars than we do about Earth's ocean depths. But researchers have evened the score at least a little with the creation of a new map of the world's seafloor. Twice as accurate as the previous version produced almost 20 years ago, the new map details thousands of previously uncharted mountains and provides new clues on the formation of the continents.
