Violent Youth Seeded The Universe With Iron
2013-10-31 05:07:20

April Flowers for redOrbit.com - Your Universe Online The universe underwent a turbulent and violent youth more than 10 billion years ago, as evidenced by iron spread evenly between galaxies in one of the largest galaxy clusters in the Universe. This violent youth was responsible for seeding the cosmos with iron and other heavy elements that are critical to life itself, according to the new study published in Nature. Scientists from the Kavli Institute for Particle Astrophysics and...

AURA announced today that Dr. Steven M. Kahn will assume the role of Director of the Large Synoptic Survey Telescope (LSST) Project effective July 1, 2013. Dr. Kahn will succeed Dr. Sidney C. Wolff and retain his current affiliation with SLAC and Stanford. LSST is the top-ranked large-scale ground-based project for the next decade as recommended by the National Research Council´s Astronomy and Astrophysics decadal survey (Astro2010). By digitally imaging the sky for a decade, the LSST...

Galaxy Could Be Teeming With 'Nomad Planets'

Researchers at the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) suggest in a new study that the heavens could be teeming with “nomad planets,” wandering through space instead of orbiting around host stars. In fact, say the researchers, there could be 100,000 times more of these planets in the Milky Way alone than there are stars. And if observations confirm this estimate, it could affect the current theories of planet formation and change our understanding of...

New research adds doubt that a prominent European astrophysics experiment may have found evidence of dark matter. In an interview, Stanford´s Stefan Funk and Justin Vandenbroucke talk about their findings, as well as how they tricked a telescope into searching for particles it wasn´t designed to detect. Like jazz musicians who make up a melody as they go along, scientists often improvise even after an experiment is underway. One recent example of this comes from the Fermi...

The Crab Nebula, one of our best-known and most stable neighbors in the winter sky, is shocking scientists with a propensity for fireworks"”gamma-ray flares set off by the most energetic particles ever traced to a specific astronomical object. The discovery, reported today by scientists working with two orbiting telescopes, is leading researchers to rethink their ideas of how cosmic particles are accelerated. "We were dumbfounded," said Roger Blandford, who directs the Kavli Institute...

What can scientists hope to learn in the coming decade about the most basic questions about the cosmos and our place in it "“ from extraterrestrial life to the evolution of the Universe "“ while keeping to an earthbound budget? That's the question at the heart of Astro2010, the new decadal survey of astronomy and astrophysics sponsored by the National Research Council that provides direction for federal funding of research in these fields for the next ten years. Shortly after the...

Using entire galaxies as lenses to look at other galaxies, researchers have a newly precise way to measure the size and age of the universe and how rapidly it is expanding, on par with other techniques. The measurement determines a value for the Hubble constant, which indicates the size of the universe, and confirms the age of the universe as 13.75 billion years old, within 170 million years. The results also confirm the strength of dark energy, responsible for accelerating the expansion of...

Jets of particles streaming from black holes in far-away galaxies operate differently than previously thought, according to a study published today in Nature. The new study reveals that most of the jet's light"”gamma rays, the universe's most energetic form of light"”is created much farther from the black hole than expected and suggests a more complex shape for the jet. The research was led by scientists at the Kavli Institute for Particle Astrophysics and Cosmology, jointly...

New images from NASA's Fermi Gamma-ray Space Telescope show where supernova remnants emit radiation a billion times more energetic than visible light. The images bring astronomers a step closer to understanding the source of some of the universe's most energetic particles -- cosmic rays. Cosmic rays consist mainly of protons that move through space at nearly the speed of light. In their journey across the galaxy, the particles are deflected by magnetic fields. This scrambles their paths and...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
