Massive Saturn Storm Churns Up Water Ice from Great Depths

Saturn Storm Churns Up Water Ice from Great Depths

A newly published study details a massive storm that erupted on Saturn in late 2010, finding that cloud particles at the top of the great storm are composed of a mix of three substances: water ice, ammonia ice, and an uncertain third constituent that is possibly ammonium hydrosulfide. Once every 30 years or so, or […]

Astronomers Use Pan-STARRS to Detect Brown Dwarf Companion Stars

Astronomers Study the Early Stages of Brown Dwarf Development

Using Pan-STARRS and UKIDSS, astronomers discovered 673 binaries with candidate brown dwarf companions. Astronomers trying to understand how the Sun and Earth formed, and why they have their characteristic properties, have made progress on a closely related problem: the nature of the lowest mass stars, so-called “brown dwarfs.” These stars have masses of less than […]

Physicists Successfully Simulate Evolution of the Early Universe

Big Bang Experiment Simulates Evolution of Early Universe

Using ultracold cesium atoms in a vacuum chamber, scientists have successfully simulated the evolution of the early universe. Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the University of Chicago. “This is the first time […]

Unique Semiconductor/Catalyst Construct Produces Hydrogen Fuel from Sunlight

Method for Making Hydrogen Fuel from Sunlight

Researchers from the Berkeley Lab have developed a method by which molecular hydrogen-producing catalysts can be interfaced with a semiconductor that absorbs visible light, producing artificial photosynthesis. In the search for clean, green sustainable energy sources to meet human needs for generations to come, perhaps no technology matches the ultimate potential of artificial photosynthesis. Bionic […]

Astronomers Discover ‘Trojan’ Asteroid Sharing the Orbit of Uranus

UBC Astronomers Discover Trojan Asteroid

Astronomers from the University of British Columbia have identified a 60 kilometer-wide asteroid that shares the orbit of Uranus. UBC astronomers have discovered the first Trojan asteroid sharing the orbit of Uranus, and believe 2011 QF99 is part of a larger-than-expected population of transient objects temporarily trapped by the gravitational pull of the Solar System’s […]

Hubble Views a Protostar in a Very Early Evolutionary Stage

Hubble Views IRAS 20324 4057

This composite Hubble image shows IRAS 20324+4057, a protostar in a very early evolutionary stage. This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast. But the meat of the story is not only what this cosmic caterpillar eats for lunch, but also what’s eating it. Harsh winds […]

Scientists Discover Mega-Canyon under Greenland Ice Sheet

Mega Canyon under Greenland Ice Sheet Discovered

Scientists have discovered a previously unknown canyon hidden beneath two kilometers of ice in Greenland. The canyon is at least 750km long and in places as much as 800m deep. Hidden for all of human history, a 460 mile long canyon has been discovered below Greenland’s ice sheet. Using radar data from NASA’s Operation IceBridge, […]

Chandra Views Milky Way’s Supermassive Black Hole Rejecting Food

Chandra Views Black Hole Rejecting Food

Using data from NASA’s Chandra X-ray Observatory, astronomers found that less than 1% of the material in the Milky Way’s supermassive black hole’s gravitational grasp appears to actually reach the event horizon, helping help explain why gas near the supermassive black hole is so faint in X-rays. The center of the Milky Way galaxy, with […]

Cassini Reveals a Rigid and Weathered Ice Shell on Titan

Cassini Data Reveals a Rigid Weathered Ice Shell on Titan

Using new data from NASA’s Cassini spacecraft, scientists from UC Santa Cruz discovered a negative correlation between the gravity and topography signals on Titan, indicating a rigid, weathered ice shell. An analysis of gravity and topography data from Saturn’s largest moon, Titan, has revealed unexpected features of the moon’s outer ice shell. The best explanation […]
