Astronomers Find Clues that May Help Identify Dark Matter

In a newly published study, astronomers used X-rays from Chandra and optical data from Hubble to help narrow down the possibilities of what dark matter can be and to set new limits on how dark matter interacts with itself. Using observations from NASA’s Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark […]

Astronomers Link Black-Hole Wind to a Galactic Gush of Star-Forming Gas

A newly published study is the first to directly connect a galaxy’s actively ‘feeding’ black hole to features found at much larger physical scales, revealing that it’s responsible for blowing star-forming gas out of the galaxy’s central regions. By combining observations from the Japan-led Suzaku X-ray satellite and the European Space Agency’s infrared Herschel Space […]

NASA Views Growth Spurt from Newborn Protostar

Satellite and ground-based data has revealed an outburst from HOPS 383. This is the first outburst astronomers have ever seen from a Class 0 object, and it appears to be the youngest protostellar eruption ever recorded. Using data from orbiting observatories, including NASA’s Spitzer Space Telescope, and ground-based facilities, an international team of astronomers has […]

Researchers Discover the Sound of Stars

A chance discovery by a team of physicists has provided experimental evidence that stars may generate sound. The study of fluids in motion – now known as hydrodynamics – goes back to the Egyptians, so it is not often that new discoveries are made. However when examining the interaction of an ultra-intense laser with a […]

Carnufex Carolinensis

New research from North Carolina State University shows that a 9-foot long crocodile ancestor may have been North America’s top predator before the dinosaurs arrived. A newly discovered crocodilian ancestor may have filled one of North America’s top predator roles before dinosaurs arrived on the continent. Carnufex carolinensis, or the “Carolina Butcher,” was a 9-foot […]

Totten Glacier Catchment is New Threat To Ocean Levels

New research reveals two seafloor gateways that could allow warm ocean water to reach the base of Totten Glacier, raising concerns about how it will affect sea level rise. Researchers at the University of Texas at Austin, NASA and other research organizations have discovered two seafloor troughs that could allow warm ocean water to reach […]

Hubble Views PGC 51017

This newly released Hubble image shows blue compact dwarf galaxy SBS 1415+437. The bright streak of glowing gas and stars in this NASA/ESA Hubble Space Telescope image is known as PGC 51017, or SBS 1415+437. It is type of galaxy known as a blue compact dwarf. This particular dwarf is well studied and has an […]

Data Suggest Saturn Moon's Ocean May Harbor Hydrothermal Activity

Using data from NASA’s Cassini spacecraft, two newly published studies reveal the first clear evidence that Saturn’s moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth. The implications of such activity on a world other than our planet open up unprecedented scientific possibilities. “These findings […]

New Study Reveals Details of Star Formation

A newly published study about the Carina Nebula is helping astronomers better understand the processes that may have contributed to the formation of the sun 4.5 billion years ago. The Carina Nebula survey is published in the Astronomical Journal. “Most stars form in giant molecular clouds, regions where the density of matter is sufficient for […]

New Dwarf Galaxies Discovered in Orbit Around the Milky Way

Astronomers from the University of Cambridge have identified nine new dwarf satellites orbiting the Milky Way, the largest number ever discovered at once. Astronomers have discovered a ‘treasure trove’ of rare dwarf satellite galaxies orbiting our own Milky Way. The discoveries could hold the key to understanding dark matter, the mysterious substance which holds our […]

Hubble Sees Multiple Images of a Highly Magnified Supernova for the First Time

Using the Hubble Space Telescope, a team of astronomers has spotted four images of a distant exploding star for the first time. The images are arranged in a cross-shaped pattern by the powerful gravity of a foreground galaxy embedded in a massive cluster of galaxies. The supernova discovery paper appears in a special issue of […]

Mars Had More Water than the Arctic Ocean

New measurements by researchers at NASA reveal that an ocean once covered approximately twenty percent of the Martian surface, making Mars is considerably wetter than many previous estimates and raising the odds for the ancient habitability of the Red Planet. A primitive ocean on Mars held more water than Earth’s Arctic Ocean, according to NASA […]

Researchers Identify a Quadruple Star System

Using the Robo-AO adaptive optics system and the PALM-3000 adaptive optics system, astronomers have identified a planet in a quadruple star system for only the second time. Growing up as a planet with more than one parent star has its challenges. Though the planets in our solar system circle just one star — our sun […]

Scientists Identify a Gene for Human Brain Size

A team of researchers has identified for the first time a gene (ARHGAP11B) that is only present in humans and contributes to the reproduction of basal brain stem cells, triggering a folding of the neocortex. About 99 percent of human genes are shared with chimpanzees. Only the small remainder sets us apart. However, we have […]

Life Possible on Titan

In a new study, chemical engineers and astronomers from Cornell University reveal that Titan could harbor methane-based, oxygen-free cells that metabolize, reproduce and do everything life on Earth does. Liquid water is a requirement for life on Earth. But in other, much colder worlds, life might exist beyond the bounds of water-based chemistry. Taking a […]

The Spatial Extent of Induced Star Formation

Researchers from the Harvard-Smithsonian Center for Astrophysics simulated galaxy collisions under a wide range of conditions in order to investigate the question of where the induced star formation is located. Collisions between galaxies, and even less dramatic gravitational encounters between them, are recognized as triggering star formation. Observations of luminous galaxies, powered by starbursts, are […]
