Research Reveals New Man-Made Ozone-Depleting Gases in the Atmosphere

New research from scientists at the University of East Anglia reveals four new man-made gases in the atmosphere that are contributing to the destruction of the ozone layer. New research published in the journal Nature Geoscience reveals that more than 74,000 tonnes of three new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been released […]

New ScienceCast Video: A Telescope Bigger than a Galaxy

A new three minute ScienceCast video looks through the biggest telescope in the history of astronomy. More than 400 years ago, Galileo turned a primitive spyglass toward the sky, and in just a few nights learned more about the unseen heavens than all of the scientists and philosophers before him, combined. Since then astronomers have […]

Hubble Views Nebula AFGL 4104

This newly released Hubble image shows nebula AFGL 4104. They say the flap of a butterfly’s wings can set off a tornado on the other side of the world. But what happens when a butterfly flaps its wings in the depths of space? This cosmic butterfly is a nebula known as AFGL 4104, or Roberts […]

WISE Survey Finds No Evidence of “Planet X”

Using data from NASA’s WISE exporter, two newly published studies reveal thousands of new stars, but no evidence of “planet X.” After searching hundreds of millions of objects across our sky, NASA’s Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed “Planet X.” […]

Astronomers Examine Star Formation in Luminous, Colliding Galaxies

By combining computer simulations with multi-band observations, two new studies examine how luminosity, star formation, dust heating, and other effects evolve during a galaxy collision. Nearly thirty years ago the Infrared Astronomy Satellite discovered that the universe contained many tremendously luminous galaxies, some more than a thousand times brighter than our own Milky Way, but […]

ALMA Reveals Unexpected Gas Clump in Debris Disc Around Beta Pictoris

Using the ALMA telescope, researchers discovered an unexpected clump of carbon monoxide gas in the dusty disc around the star Beta Pictoris. NASA Goddard’s Aki Roberge explains how observations with the Atacama Large Millimeter/submillimeter Array in Chile tell us about poison gas, comet swarms and a hypothetical planet around Beta Pictoris. Image Credit: NASA’s Goddard […]

Scientists Discover New Process that Protects Earth from Space Weather

A newly published study shows that in certain circumstances a pool of dense particles normally circling Earth can extend a long arm out to meet and help block incoming solar material. In the giant system that connects Earth to the sun, one key event happens over and over: solar material streams toward Earth and the […]

New Models Better Describe How Planet-Forming Material Around Stars is Stirred Up

Using data from NASA’s Spitzer Space Telescope, researchers have developed a new theory explaining the mystery of planet-forming disks that circle the young stars. Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006. Researchers using NASA’s Spitzer Space Telescope to study developing stars […]

Scientists Discover a Fundamental Aggravating Factor in Autoimmune Diseases

Using genetic engineering, scientists have identified a factor that may play a significant role in in autoimmune diseases. Scientists in Freiburg may have discovered a fundamental aggravating factor in autoimmune diseases. If B-lymphocytes lack the protein PTP1B, the cells will become hyperactive for stimulatory signals and can thus promote an autoimmune attack. This study offers […]

Using “Multiferroics” Researchers Make Major Improvements in Computer Processing

A team of UCLA researchers has demonstrated that using an emerging class of magnetic materials called “multiferroics” to generate spin waves could reduce wasted heat and increase power efficiency for computer processing by up to 1,000 times. Have you ever wondered why your laptop or smartphone feels warm when you’re using it? That heat is […]

NASA’s Cassini to Conduct Its 100th Flyby of the Saturn Moon Titan

NASA’s Cassini spacecraft is ready to conduct its 100th flyby of Titan. Ten years ago, we knew Titan as a fuzzy orange ball about the size of Mercury. We knew it had a nitrogen atmosphere — the only known world with a thick nitrogen atmosphere besides Earth. But what might lie beneath the hazy air […]

Astronomers Measure Distant Black Hole’s Spin

Using data from Chandra and XMM-Newton, astronomers directly measured the spin of a supermassive black hole in a quasar that is located 6 billion light years away. Astronomers have used NASA’s Chandra X-ray Observatory and the European Space Agency’s (ESA’s) XMM-Newton to show a supermassive black hole six billion light years from Earth is spinning […]
