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 […]

Engineers Design Calcium-Based Multi-Element for Liquid Batteries

New Chemistries for Liquid Batteries

In a newly published study, MIT researchers show that calcium can form the basis for both the negative electrode layer and the molten salt that forms the middle layer of the three-layer battery. Liquid metal batteries, invented by MIT professor Donald Sadoway and his students a decade ago, are a promising candidate for making renewable […]

Dawn Spacecraft Reveals Bright Spots and Color Differences on Ceres

Occator-Crater

NASA’s Dawn spacecraft reveals new images from the lowest orbit at Ceres, including highly-anticipated views of Occator Crater. NASA’s Dawn spacecraft has revealed marvelous sights on dwarf planet Ceres during its first year in orbit. Occator Crater, measuring 57 miles (92 kilometers) across and 2.5 miles (4 kilometers) deep, contains the brightest area on Ceres, […]

Yale Biologists Solve the Mystery of the Tully Monster

Mystery of the Tully Monster Solved

A newly published study from Yale University reveals that the Tully Monster had gills and a notochord, which functioned as a rudimentary spinal cord. The Tully Monster, an oddly configured sea creature with teeth at the end of a narrow, trunk-like extension of its head and eyes that perch on either side of a long, […]

Cassini Views Crater Duo on Saturn’s Moon Dione

Cassini Views a Crater Duo on Saturn's Moon Dione

This newly released Cassini image shows a pair of carters on Saturn’s moon Dione. Cassini captures a crater duo on Saturn’s moon Dione that is superimposed on older, linear features. The upper of the pair, named Italus, is overprinted on a grouping of ancient troughs called Petelia Fossae. The lower crater, Caieta, sits atop a […]

NASA Spacecraft Map Gravity on Mars, Give Best View Yet Inside Mars

New Gravity Map Gives Best View Yet Inside Mars

Scientists have used slight orbital fluctuations to map the gravity field of Mars, providing fresh insights into its crustal thickness, deep interior, and seasonal variations of dry ice at the poles. The new gravity map will also help to put future spacecraft into orbit more precisely, ensuring that the Mars fleet continues to return a […]

Scientists Discover Colossal ‘Super Spiral’ Galaxies

Superluminous Spiral Galaxies

Using archived NASA data, researchers have discovered “super spiral” galaxies that dwarf the Milky Way and compete in size and brightness with the largest galaxies in the universe. The unprecedented galaxies have long hidden in plain sight by mimicking the appearance of typical spirals. A strange new kind of galactic beast has been spotted in […]
