    A Peculiar Galactic Clash

    March 9, 2018, Categories  Astronomy/Space

    Arp 256 is a stunning system of two spiral galaxies, about 350 million light-years away, in an early stage of merging. The image, taken with the NASA/ESA Hubble Space Telescope, displays two galaxies with strongly distorted shapes and an astonishing number of blue knots of star formation that look like exploding fireworks. The star formation was triggered by the close interaction between the two galaxies. Credit: ESA/Hubble, NASA

    Galaxies are not static islands of stars – they are dynamic and ever-changing, constantly on the move through the darkness of the Universe. Sometimes, as seen in this spectacular Hubble image of Arp 256, galaxies can collide in a crash of cosmic proportions...

    Hubble Observes Exoplanet Atmosphere in more Detail than ever before

    March 4, 2018, Categories  Astronomy/Space

    A team of British and American astronomers used data from several telescopes on the ground and in space -- among them the NASA/ESA Hubble Space Telescope -- to study the atmosphere of the hot, bloated, Saturn-mass exoplanet WASP-39b, about 700 light-years from Earth. The analysis of the spectrum showed a large amount of water in the exoplanet's atmosphere -- three times more than in Saturn's atmosphere. Credit: NASA, ESA, and G. Bacon (STScI)

    An international team has used Hubble Space Telescope to study the atmosphere of the hot exoplanet WASP-39b. By combining this new data with older data they created the most complete study yet of an exoplanet atmosphere...

    Hubble Weighs in on Mass of 3 Million Billion Suns

    January 17, 2018, Categories  Astronomy/Space

    In 2014, astronomers using the NASA/ESA Hubble Space Telescope found that this enormous galaxy cluster contains the mass of a staggering three million billion suns -- so it's little wonder that it has earned the nickname of "El Gordo" ("the Fat One" in Spanish)! Known officially as ACT-CLJ0102-4915, it is the largest, hottest, and brightest X-ray galaxy cluster ever discovered in the distant universe. Credit: ESA/Hubble & NASA, RELICS

    Astronomers uncover Largest known Population of Brown Dwarfs sprinkled among Newborn stars in the Orion Nebula

    January 13, 2018, Categories  Astronomy/Space

    This image is part of a Hubble Space Telescope survey for low-mass stars, brown dwarfs, and planets in the Orion Nebula. Each symbol identifies a pair of objects, which can be seen in the symbol's center as a single dot of light. Special image processing techniques were used to separate the starlight into a pair of objects. The thicker inner circle represents the primary body, and the thinner outer circle indicates the companion. The circles are color-coded: red for a planet; orange for a brown dwarf; and yellow for a star. Located in the upper left corner is a planet-planet pair in the absence of a parent star. In the middle of the right side is a pair of brown dwarfs. The portion of the Orion Nebula measures roughly four by three light-years. Credit: NASA , ESA, and G. Strampelli (STScI)
