Classical Nova Explosion Could Have Big Impact

GK Persei Mini Supernova Explosion

Astronomers used data from the Chandra X-ray Observatory to observe the differences in GK Persei over a span of nearly 14 years, providing clues to the dynamics of other, much larger stellar eruptions. In Hollywood blockbusters, explosions are often among the stars of the show. In space, explosions of actual stars are a focus for […]

Chiron May Possess Saturn-Like Rings

Chiron May Have Saturn-like Rings

Using data from NASA’s Infrared Telescope Facility and the Las Cumbres Observatory Global Telescope Network, astronomers reveal features around Chiron that may signal rings, jets, or a shell of dust. There are only five bodies in our solar system that are known to bear rings. The most obvious is the planet Saturn; to a lesser […]

New Surface Composition Maps of Mercury Provide Clues to the Planet’s History

New Surface Composition Maps of Mercury

Using data from the MESSENGER spacecraft, scientists reveal previously unrecognized geochemical terranes of Mercury. Washington, D.C. – Two new papers from members of the MESSENGER Science Team provide global-scale maps of Mercury’s surface chemistry that reveal previously unrecognized geochemical terranes — large regions that have compositions distinct from their surroundings. The presence of these large […]

Habitable Exoplanets Could Experience a Wide Range of Climates

Habitable Exoplanets Could Experience Chaotic Resonance

New research from astronomers at the University of Washington details how some habitable exoplanets could experience wildly unpredictable climates. As telescopes of ever-greater power scan the cosmos looking for life, knowing where to look — and where not to waste time looking — will be of great value. New research by University of Washington astronomer […]

New Technique Offers Direct Stimulation of Neurons Without External Connections

New Technique Could Lead to Long-Lasting Localized Stimulation of Brain Tissue

Using external magnetic fields and injected magnetic nanoparticles, a new technique developed by researchers at MIT could lead to long-lasting localized stimulation of brain tissue without external connections. This video shows a calcium ion influx into neurons as a result of magnetothermal excitation with alternating magnetic fields in the presence of magnetic nanoparticles. Neurons on […]

Deceased Donor Kidneys with Acute Injury Can Be Used for Transplants

Study Reveals Injured Kidneys Can be Used for Transplants

New research from Yale University shows that kidneys from deceased donors that have acute injuries can be successfully used for transplants, instead of being discarded. The study finds that such kidneys may be more viable than previously thought, and should be considered to meet the growing demand for organ transplants. The study was published March […]

Cosmic Bumps on Cosmic Ripples – Analysis of Sunyaev-Zel’dovich Effect

Researchers Use Observations from the SPT to Examine the SZE Signatures

Researchers from the Harvard-Smithsonian Center for Astrophysics used the South Pole Telescope to examine the SZE signatures of galaxy clusters, reporting an unexpectedly weak SZE signal for less massive galaxy clusters. In 1969, the astrophysicists Rashid Sunyaev and Yakov Zel’dovich realized that the then recently discovered cosmic microwave background radiation (CMBR) would be distorted by […]

Curiosity Rover Delivers Rock Powder Sample

Rover Delivers Mars Rock Powder Sample

After a temporary delay, the Curiosity Mars rover used its robotic arm to sieve and deliver a rock-powder sample to an onboard instrument. The Chemistry and Mineralogy (CheMin) analytical instrument inside the rover received the sample powder. This sample comes from a rock target called “Telegraph Peak,” the third target drilled during about six months […]

Gamma-ray Emission from the Newly Discovered Dwarf Galaxy May Point to Dark Matter

Gamma Rays from a Newly Discovered Dwarf Galaxy Reticulum 2 May Point to Dark Matter

Researchers at Brown, Carnegie Mellon, and Cambridge have detected gamma ray emissions from dwarf galaxy Reticulum 2. This detection may be the signal of dark matter particles annihilating, a long-sought prediction of many dark matter theories. Providence, Rhode Island (Brown University) — A newly discovered dwarf galaxy orbiting our own Milky Way has offered up […]

Hubble Reveals Underground Ocean on Jupiter’s Moon Ganymede

Interior of Jupiter’s Largest Moon Ganymede

By watching the rocking motion of the two aurorae, astronomers have determined that a large amount of saltwater exists beneath Jupiter’s moon Ganymede. NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water […]
