More than 12 billion years ago a star exploded, glowing so brightly that it outshone its entire galaxy by a million times. This brilliant flash traveled across space for 12.7 billion years to a planet that hadn't even existed at the time of the explosion -- our Earth. By analyzing this light, astronomers learned about a galaxy that was otherwise too small, faint and far away for even the Hubble Space Telescope to see.
Researchers at NJIT's Big Bear Solar Observatory in Big Bear, Calif., have obtained new and remarkably detailed photos of the sun with the New Solar Telescope. The photographs reveal never-before-seen details of solar magnetism revealed in photospheric and chromospheric features.
Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b, is the lowest-mass planet ever detected around a star like the sun using direct imaging techniques.
Three new solar modeling developments at The University of Alabama in Huntsville (UAH) are bringing scientists closer to being able to predict the occurrence and timing of coronal mass ejections from the sun.
Probing the location of a recent short-duration gamma-ray burst in near-infrared light, astronomers using the Hubble Space Telescope found the fading fireball produced in the aftermath of the blast. The afterglow reveals for the first time a new kind of stellar blast called a kilonova.
With the signing last week of a 'master agreement' for the Thirty Meter Telescope - destined to be the most advanced and powerful optical telescope in the world - the University of California and UCLA moved a step closer to peering deeper into the cosmos than ever before.
Astronomers have discovered a graveyard of comets. The researchers describe how some of these objects, inactive for millions of years, have returned to life leading them to name the group the 'Lazarus comets'.
On average, galaxies that no longer form stars are larger today than they were several billion years ago. However, this has nothing to do with individual galaxies merging with others, as was long thought to be the case, concludes ETH-Zurich professor Marcella Carollo after evaluating data from the Hubble Space Telescope.
A NASA technologist has developed a fully automated tool that gives mission planners a preliminary set of detailed directions for efficiently steering a spacecraft to hard-to-reach interplanetary destinations, such as Mercury, Jupiter, Saturn, and most comets and asteroids.
Using Cassini data, Cornell astronomers have determined that the amount of water vapor and ice erupting from Enceladus depends on tidal forces from Saturn - the same phenomenon that creates tides on Earth.
An advanced laser system offering vastly faster data speeds is now ready for linking with spacecraft beyond our planet following a series of crucial ground tests. Later this year, ESA's observatory in Spain will use the laser to communicate with a NASA Moon orbiter.
In the science fiction show, Star Trek, teleportation is a regular and significant feature. But how much time and power is required to send the data needed to teleport a human being? University of Leicester physics students have calculated the answer to this very question.
