Latest and Breaking Space Science News

NOAA's DSCOVR going to a 'far out' orbit
(NASA/Goddard Space Flight Center) Many satellites that monitor the Earth orbit relatively close to the planet, while some satellites that monitor the sun orbit our star. DSCOVR will keep an eye on both, with a focus on the sun. To cover both the Earth and sun, it will have an unusual orbit in a place called L1.

Office of Science salutes new APS fellows
(DOE/US Department of Energy) Thirty-two researchers from national labs stewarded by the Office of Science have been elected as American Physical Society Fellows.

Satellite witnesses developing US nor'easter
(NASA/Goddard Space Flight Center) National Weather Service forecasters have been tracking a low pressure area that moved from the Midwest into the Atlantic Ocean today, and is expected to become a strong nor'easter that will bring blizzard conditions to the northeastern US The path of the system was captured in a NASA movie of NOAA's GOES-East satellite imagery.

Gigantic ring system around J1407b much larger, heavier than Saturn's
(University of Rochester) Astronomers at the Leiden Observatory, The Netherlands, and the University of Rochester, USA, have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn.

Swarm of microprobes to head for Jupiter
(Inderscience Publishers) A swarm of tiny probes each with a different sensor could be fired into the clouds of Jupiter and grab data as they fall before burning up in the gas giant planet's atmosphere. The probes would last an estimated 15 minutes according to planetary scientists writing in the International Journal Space Science and Engineering. Transmitting 20 megabits of data over 15 minutes would be sufficient to allows scientists to get a picture of a large part of the atmosphere of the planet.

Arctic ice cap slides into the ocean
(University of Leeds) Satellite images have revealed that a remote Arctic ice cap has thinned by more than 50 meters since 2012 -- about one sixth of its original thickness -- and that it is now flowing 25 times faster.

Yes, black holes exist in gravitational theories with unbounded speeds of propagation!
(World Scientific) Gravitational theories with broken Lorentz invariance have attracted a great deal of interest as they provide a test-bed of LI and offer a mechanism to improve their ultraviolet behavior, so that the theories may be renormalizable. However in such theories, particles can travel with arbitrary velocities and black holes may not exist at all. In contrast to this expectation, it has been shown that an absolute horizon exists, which traps signals despite infinitely large velocities.

H.E.S.S. finds three extremely luminous gamma-ray sources
(University of the Witwatersrand) The High Energy Stereoscopic System telescopes have again demonstrated their excellent capabilities in searching for high-energy gamma rays.

Scientists 'bend' elastic waves with new metamaterials that could have commercial applications
(University of Missouri-Columbia) Sound waves passing through the air, objects that break a body of water and cause ripples, or shockwaves from earthquakes all are considered 'elastic' waves. These waves travel at the surface or through a material without causing any permanent changes to the substance's makeup. Now, engineering researchers at the University of Missouri have developed a material that has the ability to control these waves, creating possible medical, military and commercial applications with the potential to greatly benefit society.

Stardust on ocean floor shows gold and uranium alchemy in stars is much less frequent than expected
(The Hebrew University of Jerusalem) Half the heavy elements in nature are created during stellar explosions such as supernovae or star collisions. Analyzing deep-sea samples of stardust that fell to Earth over millions of years, researchers made a surprising discovery about how frequently far-away stars produce heavy elements like gold and uranium. 'Our analysis shows about 100 times less plutonium than we expected,' says co-author professor Michael Paul at the Hebrew University's Racah Institute of Physics.
