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...

farthest cosmic lens

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...

Galaxy cluster MCS J0416.1–2403

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...

newly discovered planet in binary system

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
2014-04-22 10:48:49

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...

Hubble Images Cross-Section Of The Universe
2014-04-17 12:40:22

[ Watch the Video: Zooming In On CLASS B1608+656 ] ESA/NASA An image of a galaxy cluster taken by the NASA/ESA Hubble Space Telescope gives a remarkable cross-section of the Universe, showing objects at different distances and stages in cosmic history. They range from cosmic near neighbors to objects seen in the early years of the Universe. The 14-hour exposure shows objects around a billion times fainter than can be seen with the naked eye. This new Hubble image showcases a...

exomoon candidate
2014-04-10 12:05:00

Whitney Clavin, NASA Jet Propulsion Laboratory Titan, Europa, Io and Phobos are just a few members of our solar system's pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun? NASA-funded researchers have spotted the first signs of an "exomoon," and though they say it's impossible to confirm its presence, the finding is a tantalizing first step toward locating others. The discovery was made by watching a chance encounter of objects in our galaxy, which...

WASHINGTON, April 3, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and found it definitely lives up to its nickname -- El Gordo (Spanish for "the fat one"). http://photos.prnewswire.com/prnvar/20081007/38461LOGO By measuring how much the cluster's gravity warps images of galaxies in the distant background, a team of astronomers has calculated the cluster's mass to...

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...
