Astronomers Ready for G2’s Encounter with Supermassive Black Hole Sgr A*

As the gas cloud, called G2, edges closer to the supermassive black hole Sgr A*, astronomers at Northwestern University are hoping to learn new information on growth of supermassive black holes. Evanston, Illinois — Right now a doomed gas cloud is edging ever closer to the supermassive black hole at the center of our Milky […]

Hubble Measures “El Gordo” Galaxy Cluster, Bigger Than Previously Thought

Researchers have measured the mass of the El Gordo Galaxy Cluster, calculating the cluster’s mass to be as much as 3 million billion times the mass of our sun. NASA’s Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, cataloged as ACT-CL J0102-4915, and found it definitely lives up to […]

Fermi Data Reveal New Clues to Dark Matter

New maps from the Fermi-LAT Collaboration show that the galactic center produces more high-energy gamma rays than can be explained by known sources, suggesting that this excess emission is consistent with some forms of dark matter. A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that […]

NASA Detects Ocean Inside Saturn’s Moon Enceladus

New data from NASA’s Cassini spacecraft and Deep Space Network provide the first geophysical measurements of the internal structure of Enceladus, suggesting that it harbors a large interior ocean beneath an ice shell. NASA’s Cassini spacecraft and Deep Space Network have uncovered evidence Saturn’s moon Enceladus harbors a large underground ocean of liquid water, furthering […]

Scientists Use ‘Smart Window’ to Observe Lithium-Ion Battery Operation

By using ultrathin sheets of smart-window material, nickel oxide, as the anode in a lithium-ion battery, researchers were able to see for first time exactly what happens when the battery’s lithium ions make contact with the nickel-oxide layer and how the resulting reaction spreads out from several different points. High-tech “smart windows,” which darken to […]

Astronomers View Shell of Escaping Material Around Sakurai’s Object

Using the Altair adaptive optics system with the Gemini North Telescope, two NOAO astronomers were able to observe the shell of escaping material around the star known as Sakurai’s Object (V4334 Sgr). Stellar lifetimes are measured in billions of years, so changes in their appearance rarely take place on a human timescale. Thus an opportunity […]

Astrophysicists Challenge the Cosmological Model

By comparing the predictions of state-of-the-art supercomputer simulations with the results of sophisticated statistical analyses of the cosmic background radiation, two independent studies are challenging the cosmological model. Astronomers Professor Chris Collins and Dr Ian McCarthy from LJMU’s Astrophysics Research Institute are challenging the view that the currently preferred cosmological model of the Universe is […]

MIT Researchers Reverse a Rare Liver Disorder in Mice

In a newly published study, MIT researchers show that a new gene-editing technique, known as CRISPR, can reverse a rare liver disorder caused by a single genetic mutation. Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation. The findings, […]

Researchers Entangle Two Independent Photons with Different Frequencies

Using time-resolved measurement and active feed forward, researchers from the University of Science and Technology of China have entangled two independent photons of different colors for the first time. Entanglement has been capturing the imagination of scientists as well as the public ever since it first emerged from the newly minted quantum mechanics formalism eight […]

Arctic Melt Season is Lengthening by Several Days Each Decade

A new study by NSIDC and NASA researchers reveals that length of the melt season for Arctic sea ice is growing by several days each decade. The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic […]

New Study Reveals Amount of Water Present in the Moon May Have Been Overestimated

New computer simulations show that the unusually hydrogen-rich apatite crystals observed in many lunar rock samples may not have formed within a water-rich environment, revealing that the amount of water present in the moon may have been overestimated. The amount of water present in the moon may have been overestimated by scientists studying the mineral […]

New ESO Image of NGC 1316 and NGC 1317

By combining many individual images in the ESO archive, this new image shows NGC 1316 and its smaller neighbor NGC 1317. This new image from the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile shows two contrasting galaxies: NGC 1316, and its smaller neighbor NGC 1317. These two are quite close to each […]
