Mathematical Simulations Show Rocky Planets May Orbit Double Stars

Planet Formation Around Binary Stars

In a new study, astronomers used mathematical analysis and simulations to show that it is possible for a rocky planet to form around binary stars. To date, NASA’s Kepler space telescope has found only gas-giant planets like Saturn or Neptune orbiting binary stars. March 30, 2015 – Luke Skywalker’s home in “Star Wars” is the […]

Magnetic Fields Influence Star Formation on a Variety of Scales

Magnetic Fields Influence Star Formation

A newly published study from the Harvard-Smithsonian Center for Astrophysics reveals that magnetic fields influence star formation on a variety of scales, from hundreds of light-years down to a fraction of a light-year. Cambridge, Massachusetts – Stars form when gravity pulls together material within giant clouds of gas and dust. But gravity isn’t the only […]

HiRISE Images Reveal the Fading Scars of Mars Rover Landing

Scars on Mars from 2012 Rover Landing Fade

A series of observations from NASA’s Mars Reconnaissance Orbiter show how dark blast zones from the Curiosity rover have faded inconsistently. The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter made the observations on multiple dates from landing to last month. After fading for about two years, the pace of change […]

Hubble Views Spiral Galaxy NGC 3021

Hubble Views Spiral Galaxy NGC 3021

This newly released Hubble image shows the spiral galaxy NGC 3021, which lies about 100 million light-years away in the constellation of Leo Minor. Among many other types of stars, this galaxy contains Cepheid variable stars, which can be used work out the distance to the galaxy. These stars pulsate at a rate that is […]

VLT Confirms G2 Survived Close Approach of Supermassive Black Hole

G2 Passes Supermassive Black Hole

New VLT observations confirm that the dusty gas cloud G2 made its closest approach to the supermassive black hole at the center of the Milky Way in May 2014 and has survived the experience. The new result from ESO’s Very Large Telescope shows that the object appears not to have been significantly stretched and that […]

Antarctic Ice Shelves Rapidly Thinning, Study Reveals 18 Percent Decrease in Thickness

New Research Reveals Antarctic Ice Shelves Rapidly Thinning

New research shows that the Antarctic ice shelves are rapidly thinning, revealing an eighteen percent decrease in thickness over the course of roughly 20 years. A new study led by Scripps Institution of Oceanography at UC San Diego researchers has revealed that the thickness of Antarctica’s floating ice shelves has recently decreased by as much […]

New HIV Finding Dampens Hopes of an Impending Cure

New Finding Dampens Hopes of an HIV Cure

New research from Yale University shows that HIV can establish itself in the brain as soon as four months after initial infection, dampening the hopes of an impending cure for a disease that afflicts more than 35 million people. Within two years of infection, a genetically distinct version of HIV replicates in the brains of […]

New Findings Will Help Light the Way to Understanding Dark Energy

New Research Analyzes Several Sites Where Dead Stars Once Exploded

Astronomers used data from NASA’s Galaxy Evolution Explorer to analyze several sites where dead stars once exploded, revealing that the Type Ia supernovae affiliated with the hot, young stars were significantly more reliable at indicating distances than their counterparts. The brilliant explosions of dead stars have been used for years to illuminate the far-flung reaches […]

Chandra and Hubble Find Clues that May Help Identify Dark Matter

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 […]

A Geologic History of an Ancient Martian Lake System in Jezero Crater

Ancient Martian Lake System Records Two Water-Related Events

Using NASA data, researchers from Brown University created a geologic history of flowing water on the surface of Mars. Providence, Rhode Island (Brown University) — Researchers from Brown University have completed a new analysis of an ancient Martian lake system in Jezero Crater, near the planet’s equator. The study finds that the onslaught of water […]

New Entanglement Technique Could Make Atomic Clocks More Accurate

New Technique Could Make Atomic Clocks More Accurate

Researchers have developed a new technique that can entangle thousands of atoms with a single photon, opening the door to a new class of entangled states. Physicists from MIT and the University of Belgrade have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results, published today in […]

Black Hole ‘Wind’ Influences Evolution of Its Host Galaxy

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 Announces Progress on Asteroid Redirect Mission & Future Expeditions to Deep Space

NASA Announces Next Steps on Journey to Mars and Progress on Asteroid Initiative

In a new press release, NASA details its Asteroid Redirect Mission and reveals that it has increased the detection of near-Earth asteroids by 65 percent since launching its asteroid initiative three years ago. For ARM, a robotic spacecraft will capture a boulder from the surface of a near-Earth asteroid and move it into a stable […]

Quantum Experiment Verifies Nonlocal Wavefunction Collapse for a Single Particle

Quantum Experiment Verifies Nonlocal Wavefunction Collapse

Physicists from Griffith University have demonstrated “spooky action at a distance” for the first time with no efficiency loophole by splitting a single photon between two laboratories and experimentally testing if the choice of measurement in one lab really causes a change in the local quantum state in the other lab. An experiment devised in […]

Reg3beta Regulates Healing Process after Myocardial Infarction

Reg3beta Controls Healing Process in the Heart

A new study from the Max Planck Institute details how Reg3beta controls the wound-healing process in the myocardium by attracting immune cells to the infarct tissue. In the wake of a myocardial infarction, parts of the myocardium die and are replaced by scar tissue. The formation and stability of scar tissue is key to the […]

APEX Observations Unravel the Mystery of Nova Vulpeculae 1670

APEX Unravels the Mystery of Nova Vulpeculae 1670

New observations reveal that the star that astronomers saw appear in the sky in 1670 was not a nova, but a much rarer, violent breed of stellar collision. It was spectacular enough to be easily seen with the naked eye during its first outburst, but the traces it left were so faint that very careful […]
