redOrbit Staff & Wire Reports - Your Universe Online The amount of light originating from known populations of galaxies and quasars is far less than the amount required to explain the amount of hydrogen that helps bridge empty spaces between galaxies, according to research appearing in a recent edition of The Astrophysical Journal Letters. In fact, as lead author Juna Kollmeier of the Carnegie Institution for Science and her colleagues explained in a statement Tuesday, the...

Spiral Galaxies Larger Than Thought
2013-06-27 13:50:10

Lee Rannals for redOrbit.com - Your Universe Online Astronomers now say spiral galaxies like the Milky Way galaxy are actually larger than previously thought. Scientists from several universities used the Hubble Space Telescope to determine that normal spiral galaxies are surrounded by halos of gas that can extend to over one million light-years in diameter. With this new estimate, it brings the Milky Way from just 100,000 light-years across to roughly 1,100,000 light-years. The...

Sideline Quasars May Have Hampered Galaxy Formation
2013-03-22 04:19:47

redOrbit Staff & Wire Reports - Your Universe Online Astronomers from the University of Colorado Boulder (CU-Boulder) believe that so-called sideline quasars located on the outer fringes of a larger, brighter active galactic nucleus might have joined forces with it to prevent the formation of small galaxies billions of years ago. Michael Shull, a professor of astrophysical and planetary sciences at the university´s Center for Astrophysics and Space Astronomy, and research...

Evidence Of Gas Flow As Galactic Fuel Found
2013-01-12 08:28:26

redOrbit Staff & Wire Reports — Your Universe Online Thanks to observations obtained using the Hubble Space Telescope, researchers have discovered direct, empirical evidence of the existence of gas flows that are consumed by galaxies as fuel. A team led by Nicolas Lehner, research associate professor at the University of Notre Dame, studied data collected by the telescope´s two ultraviolet spectrographs, the Cosmic Origins Spectrograph and the Space Telescope Imaging...

Planet Devoured By Its Own Star In Secret
2012-11-20 13:37:03

Lee Rannals for redOrbit.com - Your Universe Online New observations by the Hubble Space Telescope (HST) have found a planet that is secretly being consumed by its own star. The gas giant planet is about 1.4 times the size of Jupiter and is orbiting extremely close to its parent star, completing a full orbit in just over one Earth day. Due to the close distance of orbit, a gas cloud has been "boiled off," and some of it is moving out towards interstellar space to create a shroud...

New imaging spectrograph eliminates aberrations present in existing instruments. Trenton, New Jersey (PRWEB) May 21, 2012 Princeton Instruments is pleased to introduce the IsoPlane SCT-320,The IsoPlane (patent pending) features a revolutionary new optical design that eliminates the primary aberrations present in traditional imaging spectrographs. It produces images that are clearer and sharper across the focal plane than any comparable spectrograph on the market. As a result, more photons...

New Evidence Found For Complex Molecules On Pluto's Surface
2011-12-21 04:33:06

The new and highly sensitive Cosmic Origins Spectrograph aboard the Hubble Space Telescope has discovered a strong ultraviolet-wavelength absorber on Pluto's surface, providing new evidence that points to the possibility of complex hydrocarbon and/or nitrile molecules lying on the surface, according to a paper recently published in the Astronomical Journal by researchers from Southwest Research Institute and Nebraska Wesleyan University. Such chemical species can be produced by the...
