The finding provides astrophysicists with additional insight into how planets are formed. “This is the sharpest spectrum ever obtained of an extrasolar…
On March 13, it was announced the most vigorous bursts of star birth in the cosmos took place much earlier than previously thought – results now published in a…
The Solar Wind Electron Analyzer (SWEA) was the last of the six instruments to be delivered, and was integrated late last week at Lockheed Martin in Littleton,…
Both carbon and oxygen are produced when helium burns inside of giant red stars. Carbon-12, an essential element we’re all made of, can only form when three…
There is, however, no particle radiation associated with this event, which is what would normally concern operators of interplanetary spacecraft since the…
These so-called starburst galaxies produce stars at a prodigious rate—creating the equivalent of a thousand new suns per year. Now the astronomers have found…
Many discoveries in physics came as a big surprise – for example the phenomenon, that some materials loose almost all their electrical resistance at low…
Thanks to a new high-tech gadget, astronomers have observed four planets orbiting a star relatively close to the sun in unprecedented detail, revealing the…
Instead of working with polished glass, physicists must use ingenious tricks, including shooting concentrated beams of x-rays directly into materials. These…
“We now estimate that if we were to look at 10 of the nearest small stars we would find about four potentially habitable planets, give or take,” said Ravi…
Electrically powered nano-scale lasers have been able to operate effectively only in cold temperatures. Researchers in the field have been striving to enable…
Quasars are extremely bright and powerful sources of energy that sit in the center of a galaxy, surrounding a black hole. In systems with multiple quasars, the…
On March 11, however, SDO was treated to two transits. Earth blocked SDO’s view of the sun from about 2:15 to 3:45 a.m. EDT. Later in the same day, from around…

Supernova explosions of massive stars are common in spiral galaxies like the Milky Way, where new stars are forming all the time. They are almost never seen in…
“We have found that this is the oldest known star with a well-determined age,” said Howard Bond of Pennsylvania State University in University Park, Pa., and…
