A new study by University of Wisconsin-Madison physicists mimicked solar winds in the lab, confirming how they develop and providing an Earth-bound model for the future study of solar physics.

NASA's newest planet-hunting satellite has discovered a type of planet missing from our own solar system. The finding will soon allow for study of this 'missing link' between rocky Earth-like planets and gas-dominant mini-Neptunes.

NASA's Transiting Exoplanet Survey Satellite, or TESS, has discovered three new worlds that are among the smallest, nearest exoplanets known to date. The planets orbit a star just 73 light years away and include a small, rocky super-Earth and two sub-Neptunes -- planets about half the size of our own icy giant.

NASA's Terra satellite found two small areas of strength in Tropical Storm Nari on July 26 as it began to affect Japan.

Wind shear can push clouds and thunderstorms away from the center of a tropical cyclone and that's exactly what infrared imagery from NASA's Terra satellite shows is happening in newly formed Tropical Storm 07W.

Infrared imagery from NASA's Aqua satellite found just a small area of cold clouds in thunderstorms within weakening Tropical Depression Dalila, enough to maintain it as a tropical cyclone.

A newly-discovered planet orbiting one of the brightest young stars known could provide valuable information on how planetary bodies form.

More than 100 years after Albert Einstein published his iconic theory of general relativity, it's beginning to fray at the edges, said Andrea Ghez, UCLA professor of physics and astronomy. Now, in the most comprehensive test of general relativity near the monstrous black hole at the center of our galaxy, Ghez and her research team report July 25 in the journal Science that Einstein's theory of general relativity holds up, at least for now.

Observations made with a new instrument developed for use at the 2.1-meter telescope at the National Science Foundation's Kitt Peak National Observatory have led to the discovery of the fastest eclipsing white dwarf binary yet known.
