Stellar Tape Measure
2014-04-11 05:13:14

NASA Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away -- 10 times farther than previously possible. Astronomers have developed yet another novel way to use the 24-year-old space telescope by employing a technique called spatial scanning, which dramatically improves Hubble's accuracy for making angular measurements. The technique, when applied to the age-old method for gauging distances called astronomical...

WASHINGTON, April 4, 2013 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago.

Hubble Space Telescope Breaks Record For Furthest Supernova
2013-04-04 12:49:29

ESA/Hubble The NASA/ESA Hubble Space Telescope has broken the record in the quest to find the furthest supernova of the type used to measure cosmic distances. This supernova exploded more than 10 billion years ago (redshift 1.914), at a time the Universe was in its early formative years and stars were being born at a rapid rate. The supernova, designated SN UDS10Wil, belongs to a special class of exploding stars known as Type Ia supernovae. These bright beacons are prized by astronomers...

WMAP Final Results Released

redOrbit Staff & Wire Reports - Your Universe Online The researchers in charge of an award-winning space mission that set out to collect fundamental measurements of the universe have announced they will be releasing their final results after nearly a decade of work. The Wilkinson Microwave Anisotropy Probe (WMAP), which was launched in June 2001, has collected data that has "revolutionized our view of the universe, establishing a cosmological model that explains a widely diverse...

“New Frontiers” Award For Work On “Origami Universe” Received By JHU Cosmologists

Two Johns Hopkins University research scientists who use the Japanese art of paper folding, known as origami, as a metaphor for understanding the complexity of the cosmos have been named winners of an award through the “New Frontiers in Astronomy & Cosmology International Grant and Essay Writing Competition,” funded by the John Templeton Foundation. Mark Neyrinck and Miguel Aragón-Calvo, both of the Henry A. Rowland Department of Physics and Astronomy at the...

Image 1 - Space Archive, Supernova Named in Honor of Maryland Senator

WASHINGTON, Jan. 11, 2012 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has looked deep into the distant universe and detected the feeble glow of a star that exploded more than 9 billion years ago. The sighting is the first finding of an ambitious survey that will help astronomers place better constraints on the nature of dark energy, the mysterious repulsive force that is causing the universe to fly apart ever faster.

NASA's Hubble Space Telescope has looked deep into the distant universe and detected the feeble glow of a star that exploded more than 9 billion years ago. The sighting is the first finding of an ambitious survey that will help astronomers place better constraints on the nature of dark energy, the mysterious repulsive force that is causing the universe to fly apart ever faster. "For decades, astronomers have harnessed the power of Hubble to unravel the mysteries of the universe," said John...

Journalists are invited to an up-close look at a full-size model of NASA's James Webb Space Telescope at the Maryland Science Center, located at 601 Light Street in Baltimore's Inner Harbor. The model is on display through Oct. 26 as part of the recent Association of Science-Technology Centers (ASTC) annual conference that was held in Baltimore. ASTC is a nonprofit organization of science centers and museums dedicated to furthering public engagement with science among increasingly diverse...
