Just two days earlier, the GPM satellite saw that Hermine was still generating some rainfall.



Avoiding 'traffic jam' creates impossibly bright 'lighthouse'

Thu, 08 Sep 2016 00:00:00 EDT

(National Institutes of Natural Sciences) A supercomputer recreated a blinking impossibly bright 'monster pulsar.' The central energy source of enigmatic pulsating Ultra Luminous X-ray sources (ULX) could be a neutron star according to numerical simulations performed by a research group led by Tomohisa Kawashima at the National Astronomical Observatory of Japan.



Visualizing the universe

Wed, 07 Sep 2016 00:00:00 EDT

(University of Utah) Computer scientists from the University of Utah will be working with researchers from New York University's Tandon School of Engineering and the American Museum of Natural History (AMNH) to develop OpenSpace, an open-source 3-D software for visualizing NASA astrophysics, heliophysics, planetary science and Earth science missions for planetariums and other immersive environments. The software also will be developed for use in schools and on home computers.



Reconciling dwarf galaxies with dark matter

Wed, 07 Sep 2016 00:00:00 EDT

(Carnegie Institution for Science) Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milky Way, there seem to be far too few of them compared with standard cosmological models, which raises a lot of questions about the nature of dark matter and its role in galaxy formation. New theoretical modeling work offers the most accurate predictions to date about the dwarf galaxies in the Milky Way's neighborhood.

New research reveals hundreds of undiscovered black holes

Wed, 07 Sep 2016 00:00:00 EDT

(University of Surrey) Computer simulations of a spherical collection of stars known as 'NGC 6101' reveal that it contains hundreds of black holes, until now thought impossible.Recent observations already found black hole candidates in similar systems, with this research enabling Astrophysicists to map black holes in other clusters.These systems could be the cradle of gravitational wave emission, 'ripples' in the fabric of space-time.



Hubble discovers rare fossil relic of early Milky Way

Wed, 07 Sep 2016 00:00:00 EDT

(ESA/Hubble Information Centre) A fossilized remnant of the early Milky Way harboring stars of hugely different ages has been revealed by an international team of astronomers. This stellar system resembles a globular cluster, but is like no other cluster known. It contains stars remarkably similar to the most ancient stars in the Milky Way and bridges the gap in understanding between our galaxy's past and its present.



Astronomers discover rare fossil relic of early Milky Way

Wed, 07 Sep 2016 00:00:00 EDT

(ESO) Using ESO's Very Large Telescope and other telescopes a fossilized remnant of the early Milky Way harboring stars of hugely different ages has been revealed by an international team of astronomers. This stellar system resembles a globular cluster, but is like no other cluster known. It contains stars remarkably similar to the most ancient stars in the Milky Way and bridges the gap in understanding between our galaxy's past and its present.



NASA sees post-Tropical Cyclone Hermine linger over northeastern US

Tue, 06 Sep 2016 00:00:00 EDT

(NASA/Goddard Space Flight Center) NASA and NOAA satellites continue to provide data as Post-Tropical Cyclone Hermine continues to linger south of Long Island, New York. The winds from the storm continue to affect surf from the Mid-Atlantic to Cape Cod, Massachusetts.



NASA sees Tropical Storm Lester moving away from Hawaiian islands

Tue, 06 Sep 2016 00:00:00 EDT

(NASA/Goddard Space Flight Center) Tropical Storm Lester passed the Hawaiian Islands over the holiday weekend of Sept. 4 through 6 and NASA's Aqua satellite captured an image of the weakening storm over 900 miles away from Honolulu.



NASA sees Hurricane Newton approaching landfall in Baja California, Mexico

Tue, 06 Sep 2016 00:00:00 EDT

(NASA/Goddard Space Flight Center) NASA's Terra satellite and a NASA animation of imagery from NOAA's GOES-West satellite provided views of Hurricane Newton as it neared landfall in Baja California, Mexico, today, Sept. 6.



Detailed age map shows how Milky Way came together

Tue, 06 Sep 2016 00:00:00 EDT

(University of Notre Dame) Using colors to identify the approximate ages of more than 130,000 stars in the Milky Way's halo, Notre Dame astronomers have produced the clearest picture yet of how the galaxy formed more than 13.5 billion years ago.

Brown dwarfs hiding in plain sight in our solar neighborhood

Tue, 06 Sep 2016 00:00:00 EDT

(Carnegie Institution for Science) Cool brown dwarfs are a hot topic in astronomy right now. Smaller than stars and bigger than giant planets, they hold promise for helping us understand both stellar evolution and planet formation. New work from a team including Carnegie's Jonathan Gagné has discovered several ultracool brown dwarfs in our own solar neighborhood.



Wits University scientists predict the existence of a new boson

Tue, 06 Sep 2016 00:00:00 EDT

(University of the Witwatersrand) Using data from a series of experiments that led to the discovery and first exploration of the Higgs boson at the European Organization for Nuclear Research (CERN) in 2012, scientists at the High Energy Physics Group of the University of the Witwatersrand in Johannesburg predict the existence of a new boson that might aid in the understanding of dark matter in the universe.



New simulations of wind power generation

Tue, 06 Sep 2016 00:00:00 EDT

(ETH Zurich) ETH researcher Stefan Pfenninger and his colleague Iain Staffell from Imperial College London have developed new multi-decade simulations of wind power production in Europe. In doing so, they have uncovered significant distortions in the data used in the past, and have produced fresh simulations of wind power output with country-specific corrections.



Scientists discover what extraordinary compounds may be hidden inside Jupiter and Neptune

Mon, 05 Sep 2016 00:00:00 EDT

(Moscow Institute of Physics and Technology) Scientists from MIPT's Computational Materials Discovery Lab have discovered that the depths of Uranus, Neptune and their satellites may contain extraordinary compounds, such as Carbonic and Orthocarbonic acids (the latter also known as Hitler's acid).It is no accident researchers have chosen these planets as a subject for their research. These gas giants consist mainly of hydrogen, carbon and oxygen, which are the three cornerstones of organic chemistry.



First gravitational waves form after 10 million years

Mon, 05 Sep 2016 00:00:00 EDT

(University of Zurich) If two galaxies collide, the merging of their central black holes triggers gravitational waves, which ripple throughout space. An international research team involving the University of Zurich has now calculated that this occurs around 10 million years after the two galaxies merge -- much faster than previously assumed.



Study: Earth's carbon points to planetary smashup

Mon, 05 Sep 2016 00:00:00 EDT

(Rice University) Research by Rice University Earth scientists suggests that virtually all of Earth's life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and an embryonic planet similar to Mercury.



The supernova that wasn't: A tale of 3 cosmic eruptions

Fri, 02 Sep 2016 00:00:00 EDT

(University of Arizona) Long-term observations with the Hubble Space Telescope revealed that Eta Carinae, a very massive star system that has puzzled astronomers since it erupted in a supernova-like event in the mid 19th century, has a past that's much more violent than they thought. The findings help rewrite the story of how this iconic and mysterious star system came to be and present a critical piece of the puzzle of how very massive stars die.



NASA's SDO witnesses a double eclipse

Fri, 02 Sep 2016 00:00:00 EDT

(NASA/Goddard Space Flight Center) Early in the morning of Sept. 1, 2016, NASA's Solar Dynamics Observatory, or SDO, caught both Earth and the moon crossing in front of the sun. SDO keeps a constant eye on the sun, but during SDO's semiannual eclipse seasons, Earth briefly blocks SDO's line of sight each day -- a consequence of SDO's geosynchronous orbit.
