Provided by Felicia Chou, NASA Headquarters Peering through a giant cosmic magnifying glass, NASA’s Hubble Space Telescope has spotted a tiny, faint galaxy -- one of the farthest galaxies ever seen. The diminutive object is estimated to be more than 13 billion light-years away. This galaxy offers a peek back to the very early formative years of the universe and may just be the tip of the iceberg. “This galaxy is an example of what is suspected to be an abundant, underlying...

Provided by Pam Frost Gorder, The Ohio State University Our view of other solar systems just got a little more familiar, with the discovery of a planet 25,000 light-years away that resembles our own Uranus. Astronomers have discovered hundreds of planets around the Milky Way, including rocky planets similar to Earth and gas planets similar to Jupiter. But there is a third type of planet in our solar system — part gas, part ice — and this is the first time anyone has spotted a twin...

Chuck Bednar for redOrbit.com - Your Universe Online Using a battery of observatories that included the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope, an international team of astronomers has obtained the best view to date of a collision between two galaxies that took place when the universe was just a fraction of its current age. According to ESA, the team also utilized a gravitational lens to magnify galaxy HATLAS J142935.3-002836, revealing...

redOrbit Staff & Wire Reports - Your Universe Online A massive new elliptical galaxy unexpectedly discovered using NASA’s Hubble Space Telescope is the most distant lensing galaxy ever discovered, officials from the US space agency confirmed in a statement Thursday. Lensing galaxies essentially act as a cosmic magnifying glass, and are large enough that their gravity can bend and distort light in such a way that they can make it easier to detect more distant objects in space....

WASHINGTON, July 31, 2014 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record-holder by 200 million years. http://photos.prnewswire.com/prnvar/20081007/38461LOGO These "lensing" galaxies are so massive that their gravity bends, magnifies, and distorts light from...

ESA/Hubble Information Center Stunning new observations from Frontier Fields Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble's Frontier Fields observing program, the map shows the amount and distribution of mass within MCS J0416.1–2403, a massive galaxy cluster found to be 160 trillion times the mass of the Sun. The detail in this mass map was made possible thanks...

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have located a new terrestrial planet in a binary star system located roughly 3,000 light-years from Earth, according to new research appearing in the July 4 edition of the journal Science. Ohio State University professor Andrew Gould and four international teams of scientists used the technique of gravitational microlensing to discover the new planet, which is roughly twice the mass of Earth and orbits one of its...

Brightening Star Offers Astronomers New Way To Study Binary Systems

Brett Smith for redOrbit.com - Your Universe Online Researchers searching for planets orbiting around a distant star look for a signature dimming of that star’s light, but what if the distant star suddenly gets a bit brighter? Astronomers from the University of Washington observed just such a phenomenon, but instead of concluding they had found an ‘upside-down’ planet, the scientists realized they had found a new way to study binary star systems, according to their report...

The cluster CL0024+17, located in Pisces, is a galaxy cluster that is allowing astronomers to probe the distribution of dark matter in space. Dark matter does not reflect light and therefore cannot be seen. It is only detectable by the way its gravity affects the lights around it. Using gravitational lensing astronomers observe the distorted light around the dark matter and are able to tell where it is located within a cluster. A dark matter ring found near the cluster's center, by...

Gravitational Lens -- A gravitational lens is formed when the light from a very distant, bright object (such as a quasar) is "bent" around a massive object (such as a massive galaxy) between the bright object and the viewer. The process is known as gravitational lensing, and was one of the predictions made by Einstein's general relativity. Description In a gravitational lens, the gravity from the massive object bends light as a lens might. As a result, the path of the light from a...

barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
