Milky Way’s Most Distant Stellar Stream Confirmed

  A stream of at least 150 ancient variable stars has been confirmed to extend some 130,000 light-years beyond our own galaxy’s stellar halo — on the fringes of the Intergalactic Medium, where aside from hot gas and dark matter, space-time becomes as sparse as the deep Sahara. The central disk of our Milky Way [continue reading]

Experiment Shines New Light on Giant Planets and White Dwarfs

  An international team led by researchers from the University of Warwick and Oxford University is now dealing with unexpected results of an experiment with strongly heated graphite (up to 17,000 degrees Kelvin). The findings may pose a new problem for physicists working in laser-driven nuclear fusion and may also lead astrophysicists to revise our [continue reading]

Fate of Solar System Shown by Reborn Star

  Astronomers have found evidence for a dying Sun-like star coming briefly back to life after casting its gassy shells out into space, mimicking the possible fate our own Solar System faces in a few billion years. The intricate pattern of planetary nebula Abell 30 is revealed in these images that combine optical Hubble Space [continue reading]

Massive Star Has Extreme Large Magnetic Field

  A group of astronomers led by Gregg Wade of the Royal Military College of Canada have used the Hobby-Eberly Telescope (HET) at The University of Texas at Austin’s McDonald Observatory and the Canada-France Hawaii Telescope (CFHT) on Hawaii’s Mauna Kea to measure the most magnetic massive star yet. Their work is published in yesterday’s [continue reading]
