Newly Released Cassini Image – Saturn Askew

New Image of Saturn from Cassini

Another great image of Saturn from NASA’s Cassini Spacecraft. As a convention for public release, Cassini images of Saturn are generally oriented so that Saturn appears north up, but the spacecraft views the planet and its expansive rings from all sorts of angles. Here, a half-lit Saturn sits askew as tiny Dione (698 miles or […]

Journey to the Center of the Milky Way

Hubble Views the Center of the Milky Way

Using Hubble, astronomers peer through the dust which normally obscures the view of the center of the Milky Way. Peering deep into the heart of our home galaxy, the Milky Way, the NASA/ESA Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Apart from a few, blue, foreground stars, almost […]

Researchers Discover 305 Million-Year-Old “Early Spider” Fossil

305 Million-Year-Old Early Spider Fossil

A team of scientists has discovered the fossil of a 305 million-year-old arachnid, revealing more about the early origins of modern-day spiders. The new species, named Idmonarachne brasieri in honor of Professor Martin Brasier, University of Oxford, who passed away in December 2014, was found in Montceau-les-Mines, France, and researchers from The University of Manchester, […]

Astronomers Reveal a Planet Forming in an Earth-Like Orbit Around Young Star TW Hydrae

Astronomers Find a Planet Forming in an Earth-like Orbit around a Young Star

Using data from the Atacama Large Millimeter/submillimeter Array, astronomers reveal a planet-forming disk in unprecedented detail, revealing a series of concentric dusty bright rings and dark gaps, including intriguing features that suggest a planet with an Earth-like orbit is forming there. Disks of dust and gas that surround young stars are the formation sites of […]

New Genome-Wide Analysis Links Marijuana Dependence and Major Depression

New Study Links Genes to Marijuana Dependence and Major Depression

A newly published genome-wide analysis of more than 14,000 individuals has identified several gene variants that increase risk of cannabis dependence. The analysis also suggests that the genetic risk for dependence on marijuana is associated with a higher inherited risk of major depression. The new study is published in the journal JAMA Psychiatry. The study […]

Astronomers Identify Likely Trigger for Milky Way’s Youngest Supernova

Astronomers Identify Trigger for Milky Way's Youngest Supernova

Using NASA’s Chandra X-ray Observatory and the NSF’s Jansky Very Large Array, astronomers have determined the likely trigger for the most recent supernova in the Milky Way. Astronomers had previously identified G1.9+0.3 as the remnant of the most recent supernova in our Galaxy. It is estimated to have occurred about 110 years ago from the […]

A New Approach to Designing Hydrogen-Resistant Zirconium Alloys

Designing Hydrogen-Resistant Zirconium Alloys

Researchers from MIT have developed a new approach to designing hydrogen-resistant zirconium alloys, which could be useful in nuclear reactors. High-tech metal alloys are widely used in important materials such as the cladding that protects the fuel inside a nuclear reactor. But even the best alloys degrade over time, victims of a reactor’s high temperatures, […]

Cassini Views Saturn’s Moons Enceladus and Janus

Cassini Views Moons Enceladus and Janus

This newly released Cassini image shows Saturn’s Moons Enceladus and Janus. When taking images in directions opposite from the sun, most objects appear dark. Surprisingly, however, some of Saturn’s rings get brighter. Parts of Saturn’s main rings appear dark in backlit views, particularly the dense B ring. However, some rings are comparatively tenuous and made […]

Astronomers Investigate the Mystery of Migrating ‘Hot Jupiters’

Hot Jupiter HD 80606b

Using infrared light, NASA’s Spitzer Space Telescope measured the extreme temperature swings of exoplanet HD 80606b. The last decade has seen a bonanza of exoplanet discoveries. Nearly 2,000 exoplanets — planets outside our solar system — have been confirmed so far, and more than 5,000 candidate exoplanets have been identified. Many of these exotic worlds […]

New Findings Provide a Design for an HIV Vaccine Germline-Targeting Immunogen

Scientists Announce New Anti-HIV Agent

A team of researchers has found HIV-1 broadly neutralizing antibody precursor B cells that are present in most people, and has described the design of an HIV vaccine germline-targeting immunogen capable of binding those B cells. Some people infected with HIV naturally produce antibodies that effectively neutralize many strains of the rapidly mutating virus, and […]

Cassini Reveals Moons of Saturn May Be Only 100 Million Years Old

Saturn's Moon Tethys

A newly published study reveals that Saturn’s moon Rhea and all other moons and rings closer to Saturn may be only 100 million years old. Outer satellites (not pictured above), including Saturn’s largest moon Titan, are probably as old as the planet itself. New research suggests that some of Saturn’s icy moons, as well as […]

Hubble Image of the Week – A Distinctly Disorganized Dwarf Galaxy

Dwarf Galaxy UGC 4459

This newly released Hubble image shows dwarf galaxy UGC 4459, which is located approximately 11 million light-years away. Despite being less famous than their elliptical and spiral galactic cousins, irregular dwarf galaxies, such as the one captured in this NASA/ESA Hubble Space Telescope image, are actually one of the most common types of galaxy in […]

Astronomers Identify a Signature of Dark Matter Annihilation

Astronomers Detect the Signature of Dark Matter Annihilation

By studying the spatial distribution of gamma-ray emission in the Milky Way, astronomers believe they have identified a signature of dark matter annihilation. We live in a dramatic epoch of astrophysics. Breakthrough discoveries like exoplanets, gravity waves from merging black holes, or cosmic acceleration seem to arrive every decade, or even more often. But perhaps […]

New Horizons Views Frozen, Former Lake of Liquid Nitrogen

New Horizons Ancient Views Frozen Pond

This newly released image shows a frozen, former lake of liquid nitrogen, which is located in a mountain range just north of Pluto’s informally named Sputnik Planum. NASA’s New Horizons spacecraft spied several features on Pluto that offer evidence of a time millions or billions of years ago when – thanks to much higher pressure […]

Scientists Discover a Binary Companion for a Type Ia Supernova

Astronomers Discover a Binary Companion for a Type Ia Supernova

A newly published study details evidence for the interaction between a normal Type Ia supernova and a non-degenerate binary companion. A team of astronomers including Harvard’s Robert Kirshner and Peter Challis has detected a flash of light from the companion to an exploding star. This is the first time astronomers have witnessed the impact of […]

VLT Survey Telescope Views Wolf-Lundmark-Melotte Galaxy

Astronomers View Wolf-Lundmark-Melotte Galaxy

This newly released image shows the Wolf-Lundmark-Melotte galaxy. This scene, captured by ESO’s OmegaCAM on the VLT Survey Telescope, shows a lonely galaxy known as Wolf-Lundmark-Melotte, or WLM for short. Although considered part of our Local Group of dozens of galaxies, WLM stands alone at the group’s outer edges as one of its most remote […]

Chandra Observations Show Solar Storms Trigger Jupiter’s ‘Northern Lights’

Chandra Reveals Jupiter’s Northern Lights

Using data from NASA’s Chandra X-Ray Observatory, astronomers show that solar storms trigger Jupiter’s intense ‘Northern Lights’ by generating a new X-ray aurora that is eight times brighter than normal and hundreds of times more energetic than Earth’s aurora borealis. It is the first time that Jupiter’s X-ray aurora has been studied when a giant […]
