A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, according to astrophysicists at Southern Methodist University, Dallas.
Earth's magnetic field protects us from the dangerous radiation of space, but it is not as permanent as we might believe. Scientists at the European Geosciences Union General Assembly present new information about an 'excursion' ...
The total solar eclipse isn't the only reason to keep your eyes to the sky this year. For the first time in 80 years, a star system 3,000 light years away will be visible to the naked eye thanks to a once-in-a-lifetime nova ...
Potential signs of the rainbow-like "glory effect" have been detected on a planet outside our solar system. Glory are colorful concentric rings of light that occur only under peculiar conditions.
Among the more than 4,000 known exoplanets, KOI-456.04 is something special: less than twice the size of Earth, it orbits a sun-like star. And it does so with a star-planet distance that could permit planetary surface temperatures ...
The last time a total solar eclipse cast its shadows across the United States in August 2017, Jenée Chizick-Agüero, the founder and publisher of Motivos magazine, was pregnant with her son.
New data from NASA's Cassini mission, combined with measurements from the two Voyager spacecraft and NASA's Interstellar Boundary Explorer, or IBEX, suggests that our sun and planets are surrounded by a giant, rounded system ...
China's Experimental Advanced Superconducting Tokamak (EAST) made an important advance by achieving a stable 101.2-second steady-state high confinement plasma, setting a world record in long-pulse H-mode operation on the ...
An international team of astronomers reports the detection of two new exoplanets orbiting an evolved sun-like star known as HD 137496. The newly found extrasolar worlds, identified using NASA's Kepler spacecraft, were classified ...
