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 has awarded the Aircraft Maintenance, Logistics, Integration, Configuration Management and Engineering (ALICE) contract to Yulista Tactical Services, LLC, in Huntsville, Alabama.
(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.
(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.
(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.
(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.
(Goethe University Frankfurt) Since their discovery in the 1960s, scientists have sought to answer an important question: How massive can neutron stars actually become? By contrast to black holes, these stars cannot gain in mass arbitrarily; past a certain limit there is no physical force in nature that can counter their enormous gravitational force. For the first time, astrophysicists at Goethe University Frankfurt have succeeded in calculating a strict upper limit for the maximum mass of neutron stars.
(NASA/Goddard Space Flight Center) Heavy rain surrounded Tropical Cyclone Berguitta as it continued to move toward the island of Mauritius in the Southern Indian Ocean. NASA calculated the rate in which rain was falling within the hurricane-strength storm in the Southern Indian Ocean.
(National Academies of Sciences, Engineering, and Medicine) The National Academy of Sciences will honor 19 individuals with awards in recognition of their extraordinary scientific achievements in a wide range of fields spanning the physical, biological, and medical sciences.
(European Geosciences Union) The European Geosciences Union (EGU) has named journalists Julia Rosen and Vivien Cumming as the winners of its 2018 Science Journalism Fellowship. Rosen will receive 2,200 to travel to the UK to write about the role of soil in the phosphorus crisis, while Cumming is awarded 2,800 to follow scientists in Myanmar to tell the story of carbon in rivers.
