Precise Radio-Telescope Measurements Advance Frontier Gravitational Physics
(PhysOrg.com) -- Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a ...
A cool discovery about the Sun's next-door twin
(Phys.org)—ESA's Herschel space observatory has detected a cool layer in the atmosphere of Alpha Centauri A, the first time this has been seen in a star beyond our own Sun. The finding is not only important ...
Space instrument adds big piece to the solar corona puzzle
(Phys.org)—The Sun's visible surface, or photosphere, is 10,000 degrees Fahrenheit. As you move outward from it, you pass through a tenuous layer of hot, ionized gas or plasma called the corona. The corona ...
Hinode to support ground-based eclipse observations

Something strange is about to happen to the shadows beneath your feet.
Eclipses' effect on wind revealed
Solar eclipses don't just turn the lights out; they also make the wind slow down and change direction.
Future NASA mission to sun 'a life's dream' for some

New evidence to solve the mystery of the 'eclipse wind'
(PhysOrg.com) -- Solar eclipses are not only amazing celestial spectacles - they also cause subtle changes to the weather here on Planet Earth, according to meteorologists.
A serendipitous gravitational lens
(PhysOrg.com) -- The path traveled by a light beam will bend in the presence of matter. This remarkable prediction, reached by Einstein in his theory of general relativity, was confirmed by observations of ...
Moon's shadow, like a ship, creates waves
During a solar eclipse, the Moon's passage overhead blocks out the majority of the Sun's light and casts a wide swath of the Earth into darkness. The land under the Moon's shadow receives less incoming energy ...
LRO takes extreme close-up of eclipse
