The Deepest Probe of the Universe Ever

The Deepest Probe of the Universe Ever

  NASA’s Great Observatories are teaming up to look deeper into the Universe than ever before. With a boost from natural “zoom lenses” found in space, they should be able to uncover galaxies that are as much as 100 times fainter than what the Hubble, Spitzer, and Chandra space telescopes can typically see. Abell 2744 [continue reading]

Most Distant Galaxy is Forming Stars Extremely Fast

Most Distant Galaxy is Forming Stars Extremely Fast

  University of Texas at Austin astronomer Steven Finkelstein has led a team that has discovered and measured the distance to the most distant galaxy ever found. The galaxy is seen as it was at a time just 700 million years after the Big Bang. An artist’s rendition of the newly discovered most distant galaxy [continue reading]

Two Cosmic Explosions Unveiled

Two Cosmic Explosions Unveiled

  A team of researchers including Carnegie’s Mansi Kasliwal and John Mulchaey used a novel astronomical survey software system—the intermediate Palomar Transient Factory (iPTF)—to link a new stripped-envelope supernova, named iPTF13bvn, to the star from which it exploded. The iPTF team also pinpointed the first afterglow of an explosion called a gamma-ray burst that was [continue reading]

Heaviest Black Holes Grown Up in Galactic Cities

Heaviest Black Holes Grown Up in Galactic Cities

  A research team, led by a researcher at the National Astronomical Observatory of Japan (NAOJ), discovered that the heaviest black holes tend to be located in galactic environments with higher density. This finding indicates that galaxies in a dense area often merge together, causing the growth of supermassive black holes. An artist’s illustration of galaxy distribution, [continue reading]

Distant, Massive Star is About to Explode

Distant, Massive Star is About to Explode

  An international team of astronomers has observed part of the final death throes of the largest known star in the Universe as it throws off its outer layers. The discovery, by a collaboration of scientists from the UK, Chile, Germany and the USA, is a vital step in understanding how massive stars return enriched [continue reading]

Astronomers Map Where Stars Are Born

Astronomers Map Where Stars Are Born

  A team of astronomers led by Yancy Shirley at the University of Arizona’s Steward Observatory has completed the largest-ever survey of dense gas clouds in the Milky Way – pockets shrouded in gas and dust where new stars are being born. Cataloging and mapping more than 6,000 gas clouds, the survey allows astronomers to [continue reading]
