A 3D Map of the Adolescent Universe

Using a new technique similar to x-ray computer-tomographic imaging, a team of astronomers has created the first three-dimensional map of the adolescent Universe – just 3 billion years after the Big Bang. Using extremely faint light from galaxies 10.8-billion light years away, scientists have created one of the most complete, three-dimensional maps of a slice […]

Fermi Discovers Signs of Starquakes in Magnetar Storm

Using data from NASA’s Fermi Gamma-ray Space Telescope, astronomers have discovered underlying signals related to the rapid-fire “storm” of high-energy blasts detected in 2009 from a highly magnetized neutron star. Such signals were first identified during the fadeout of rare giant flares produced by magnetars. Over the past 40 years, giant flares have been observed […]

Study Reveals Black Holes Can Block the Formation of New Stars

A new study from Johns Hopkins University reveals that massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, providing crucial new evidence that it is these jets of “radio-frequency feedback” streaming from mature galaxies’ central black holes that prevent hot free gas from cooling and […]

Yale Engineers Develop a Chip Scale Device That Uses Interaction Free Measurement

Engineers at the Yale School of Engineering & Applied Science have developed a chip-scale device that uses the wave-particle duality of single photons to sense the presence of an object without interacting with it – a technique known as “interaction-free measurement.” “Our device uses silicon photonics to create interaction-free measurement on an integrated chip—something previously […]

Saturn Moon Mimas May Have a Fossil Core or an Ocean

New data from NASA’s Cassini Spacecraft reveal that Saturn’s moon Mimas may have a liquid water ocean beneath the moon’s impact-battered surface. A new study focused on the interior of Saturn’s icy moon Mimas suggests its cratered surface hides one of two intriguing possibilities: Either the moon’s frozen core is shaped something like a football, […]

Study Questions 21 Day Quarantine For Ebola

A new study from Drexel University suggests that 21 days might not be enough to completely prevent spread of Ebola, revealing that there could be up to a 12 percent chance that someone could be infected even after the 21-day quarantine. As medical personnel and public health officials are responding to the first reported cases […]

APEX Reveals Star Formation in Unexpected Places

A team of astronomers used the APEX telescope to probe the Spiderweb Cluster, revealing that much of the star formation taking place is hidden by dust and occurring in unexpected places. Galaxy clusters are the largest objects in the Universe held together by gravity but their formation is not well understood. The Spiderweb Galaxy (formally […]

Herschel Views the Debris Disc of Solar Analogue Tau Ceti

Astronomers from the Harvard-Smithsonian Center for Astrophysics studied the debris disc around τ Ceti, revealing that a Jupiter-mass planet could not be present in this system – making it less than ideal as a Solar system analog. Although thousands of exoplanets and hundreds of planetary systems (stars with multiple exoplanets) are now known, astronomers still […]

NASA Prepares for Comet Siding Spring to Pass Mars

NASA is preparing its science fleet for comet Sliding Spring’s close encounter with Mars, which will occur on October 19 when Sliding Spring passes within about 87,000 miles of the Red Planet. NASA’s extensive fleet of science assets, particularly those orbiting and roving Mars, have front row seats to image and study a once-in-a-lifetime comet […]

Yale Engineers Develop System for Quantum Communication

Using microwaves and magnets, researchers at the Yale School of Engineering & Applied Science developed a hybrid system for quantum communication. Yale engineers have developed a hybrid system that strongly couples magnons—the smallest unit of measurement for a magnetic spin excitation—with microwave photons. According to the researchers, the hybrid system achieved an ultrahigh coherence between […]

NuSTAR Discovers Shockingly Bright Dead Star

Using NASA’s Nuclear Spectroscopic Telescope Array, astronomers have detected the brightest pulsar to date, located about 12 million light-years away in the galaxy Messier 82. Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar – a dense stellar remnant left over from a […]

Antarctic Sea Ice Reaches New Maximum

Long-term satellite records show that the five-day average of Antarctic sea ice extent reached a new record high this year. This year, Antarctic sea ice reached a record maximum extent while the Arctic reached a minimum extent in the ten lowest since satellite records began. Why are these trends going in opposite directions? Image Credit: […]
