Vivid images of a sunspot formation in action has revealed startling new clues that may help scientists understand how and why these unusual phenomena occur on the surface of the Sun.
Have you ever ordered a dinner for two... for just yourself? Apparently, the growing star Kepler-56 is doing just that. Astronomers have determined that Kepler-56 will be swallowing two of its orbiting planets whole as it becomes a red giant.
NASA has just released stunning footage of a massive eruption of solar material that occurred on the surface of the Sun earlier this month.
NASA has recently greenlighted a private group to attempt to "reboot" a 35-year-old spacecraft currently drifting through space with no mission. The spacecraft will be swinging the closest it's been to Earth in 30 years, giving scientists a small window of time to contact the craft and get it working once more.
Activity on the Sun sparks more lightning strikes on Earth, a new study suggests - knowledge that may make it possible to predict when these hazardous storms will hit.
A NASA spacecraft recently spotted a square-shaped "hole" formed by solar wind on the surface of the Sun.
NASA has unveiled a video of a solar flare erupting from the Sun's surface, calling the unprecedented images the best-observed ever. Four different NASA spacecraft and one ground-based observatory worked in unison to capture the flare.
The newly discovered "hypervelocity star" may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious dark matter surrounding the galaxy, astronomers report.
Tiny, multilayer stacks of solar cells are able to generate ultrahigh efficiency power, researchers at the University of Illinois at Urbana-Champaign report.
Astronomers stumbled upon an "upside-down planet" that offers a new method for studying binary star systems.
Comet ISON, the fast approaching comet which may be visible to the naked eye later this year, is the subject of a great photo op taken by the Hubble telescope.
A new look at the plasma eruption and subsequent splashdown that took place on the surface of the Sun during the summer of 2011 reveals how the event, caught in dramatic detail by NASA's Solar Dynamics Observatory, may provide insights into the evolution of stars.
Comet Lovejoy made a wall of fame all of its own after successfully sailing through the Sun’s hot atmosphere in 2011, coming within 87,000 miles of its surface and emerging intact. Now, some two years later, astronomers reveal in a study published in the journal Science how, in watching the hurtling ice ball as it grazed the Sun, they were able to discover new insights about the solar magnetic field.
NASA’s newest satellite is designed to provide the most detailed look yet at the Sun’s lower atmosphere from which most of its ultraviolet emission is generated.
