    Green pea galaxy provides insights to early universe evolution
    http://phys.org/news/2016-01-big-revealed-early-universe.html

    Newly formed dwarf galaxies were likely the reason that the universe heated up about 13 billion years ago, according to new work by an international team
    of scientists that included a University of Virginia researcher. The finding opens an avenue for better understanding the early period of the universe's
    14 billion year history.

    Using data from an ultraviolet spectrometer aboard the Hubble Space Telescope, the team discovered a nearby compact dwarf galaxy emitting a large number of
    ionizing photons into the intergalactic medium, or the space between galaxies. Scientists believe those photons are responsible for the universe's re-ionization.

    "This galaxy appears to be an excellent local analog of the numerous dwarf galaxies thought to be responsible for the reionization of the early universe," Trinh
    said. "The finding is significant because it gives us a good place to look for probing the reionization phenomenon, which took place early in the formation of
    the universe that became the universe we have today."

    Buenos Aires: Argentina scientists said thay have discovered a meteorite in northern Argentina,
    which is believed to be the second largest meteor in the world.

    The meteorite weighing over 30 tonnes was found in the town of Gancedo, 1,085 km north of capital
    Buenos Aires, Mario Vesconi, president of the Astronomy Association of Chaco, said on Monday.

    Phys. Rev. Lett. 117, 091101 (2016) - Testing General Relativity with Accretion-Flow Imaging of Sgr ${\mathrm{A}}^{*}$
    http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.117.091101

    The Perimeter Institute published today that a team led by the Institute's Tim Johannsen along with the University
    of Waterloo have demonstrated a new method for testing the theory of general relativity using black holes.

    They used the Event Horizon Telescope which consists of a global network of radio telescopes.

    Astronomers observe star reborn in a flash | ESA/Hubble
    http://www.spacetelescope.org/news/heic1618/
    An international team of astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic
    increases in the temperature of the star SAO 244567 have been observed. Now the star is cooling again, having been reborn into an earlier phase
    of stellar evolution. This makes it the first reborn star to have been observed during both the heating and cooling stages of rebirth.

    Astronomers discover two new inflated 'hot Jupiters'
    http://phys.org/news/2016-09-astronomers-inflated-hot-jupiters.html

    An international team of astronomers led by Joel Hartman of Princeton University has detected two new "hot Jupiter" exoplanets, less massive than our
    solar system's biggest planet, but with a radius larger than they should have. The findings are reported in a paper published Sept. 9 on arXiv.org.

    The newly found exoworlds, designated HAT-P-65b and HAT-P-66b, were classified as "hot Jupiters" as they are gas giant planets similar in characteristics
    to Jupiter, with orbital periods of less than 10 days. They have high surface temperatures as they orbit their host stars very closely. However, the new
    alien worlds are much larger in diameter than expected, which led astronomers to conclude that these planets must have undergone an inflation process.

    HAT-P-65b and HAT-P-66b were detected by the Hungarian-made Automated Telescope Network (HATNet). The team also conducted follow-up spectrographic and
    photometric observations to determine physical characteristics of these planets.

    Nearby Exo-Earth Family Withstands Extreme Scrutiny | Gemini Observatory
    http://www.gemini.edu/node/12567
    The discovery of three Earth-sized planets likely orbiting a low-mass star is looking like the real thing.

    Astronomers combined the power of the 8-meter Gemini South telescope in Chile with an extremely high-resolution camera to scrutinize the star TRAPPIST-1.
    Previous observations of the star, which is only about 8% the mass of our Sun, revealed dips in the star’s light output that would be expected if several
    Earth-sized planets orbited the star. However, the situation would be greatly complicated if, upon closer examination, the star was found to have
    a yet-unseen stellar companion.

    No such companion was found with Gemini, which essentially seals the case for multiple Earth-sized planets orbiting TRAPPIST-1.

    Explaining why the universe can be transparent
    http://phys.org/news/2016-09-universe-transparent.html

    Two papers published by an assistant professor at the University of California, Riverside
    and several collaborators explain why the universe has enough energy to become transparent.

    The study led by Naveen Reddy, an assistant professor in the Department of Physics and Astronomy at UC Riverside,
    marks the first quantitative study of how the gas content within galaxies scales with the amount of interstellar dust.

    This analysis shows that the gas in galaxies is like a "picket fence," where some parts of the galaxy have little gas
    and are directly visible, whereas other parts have lots of gas and are effectively opaque to ionizing radiation.
    The findings were just published in The Astrophysical Journal.

    Several European countries already have societies dedicated to the rapidly growing field of astrobiology. Now Germany is getting one, too.
    The German Astrobiology Society held its first meeting last week in Berlin to discuss administrative details for the new organization and
    talk science at the same time. The DAbG, as it’s called, will be the newest member of the European Astrobiology Network Association, EANA.

    The meeting’s scientific program included discussions of organic compounds in space, the origin and evolution of life, the habitability of
    planets, and life detection. The first day’s keynote lecture, by Pascale Ehrenfreund, the new director of the German AeroSpace Center, was
    on the search for life in the universe.

    Deep-sea drilling expedition to look for life's limits in scalding environments | Science | AAAS
    http://www.sciencemag.org/...09/deep-sea-drilling-expedition-look-lifes-limits-scalding-environments
    A new ocean drilling expedition will try to settle the question by drilling into crust where high temperatures are found unusually close to the sea floor,
    bringing life’s thermal limit within reach. On 13 September, the research vessel Chikyu will set sail from Shimizu, Japan, and sink its bits into a patch
    of ocean floor where the sediments should reach 130°C at the maximum drill depth of 1260 meters. Somewhere along the way, the team expects, life should
    succumb to rising temperatures.
