(Johns Hopkins University) A planet can be no bigger than about 10 times the size of Jupiter, an astrophysicist has calculated.

Astronomers produce first detailed images of surface of giant star

(Georgia State University) An international team of astronomers has produced the first detailed images of the surface of a giant star outside our solar system, revealing a nearly circular, dust-free atmosphere with complex areas of moving material, known as convection cells or granules, according to a recent study.

NASA Briefing Thursday Will Preview Upcoming US Spacewalks

American and Japanese astronauts aboard the International Space Station will embark on a pair of spacewalks Jan. 23 and 29 to service the station’s robotic arm. Experts from NASA and the Canadian Space Agency (CSA) will preview this work in a briefing at 2 p.m. EST Thursday, Jan. 18, at NASA’s Johnson Space Center in Houston.

Massachusetts Students to Speak with Astronauts on Space Station

Students at Framingham State University (FSU) in Massachusetts will speak with astronauts living, working, and doing research aboard the International Space Station at 12:15 p.m. EST Friday, Jan. 19. The 20-minute, Earth-to-space call will air live on NASA Television and the agency’s website.

U.S. Cargo Spacecraft Set for Departure from International Space Station

After delivering more than 4,800 pounds of science and supplies to the International Space Station, a SpaceX Dragon cargo spacecraft will depart the orbiting laboratory on Saturday, Jan. 13. NASA will provide live coverage of Dragon's departure beginning at 4:30 a.m. EST.

NASA Awards Contract for Aircraft Operations Support

NASA has awarded the Aircraft Maintenance, Logistics, Integration, Configuration Management and Engineering (ALICE) contract to Yulista Tactical Services, LLC, in Huntsville, Alabama.

Study shows first evidence of winds outside black holes throughout their...

(University of Alberta) New research shows the first evidence of strong winds around black holes throughout bright outburst events when a black hole rapidly consumes mass. The study, published in Nature, sheds new light on how mass transfers to black holes and how black holes can affect the environment around them. The research was conducted by an international team of researchers, led by scientists in the University of Alberta's Department of Physics.

Smartphones come in handy for the rare cosmic particles search

(National Research University Higher School of Economics) Researchers from the Laboratory of Methods for Big Data Analysis (LAMBDA) at the Higher School of Economics have improved their way of analyzing ultra-high energy cosmic rays (UHECR) with the use of mobile phones. The work has been carried out as part of the CRAYFIS experiment and the results were presented at the 22nd International Conference on Computing in High Energy and Nuclear Physics.

Titan topographic map unearths cookie-cutter holes in moon’s surface

(Cornell University) Using the now-complete Cassini data set, Cornell University astronomers have created a new global topographic map of Saturn's moon Titan that has opened new windows into understanding its liquid flows and terrain. Two papers, recently published in Geophysical Review Letters, describe the map and discoveries arising from it.

Odd behavior of star reveals lonely black hole hiding in giant...

(ESO) Astronomers using ESO's MUSE instrument on the Very Large Telescope in Chile have discovered a star in the cluster NGC 3201 that is behaving very strangely. It appears to be orbiting an invisible black hole with about four times the mass of the sun -- the first such inactive stellar-mass black hole found in a globular cluster and the first found by directly detecting its gravitational pull.
