SDO sees returning sunspot produce mid-level flare

The sun emitted a mid-level solar flare, peaking at 12:48 p.m. EST on Nov. 16, 2014. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of ...

New materials for more powerful solar cells

Applying a thin film of metallic oxide significantly boosts the performance of solar panel cells—as recently demonstrated by Professor Federico Rosei and his team at the Énergie Matériaux Télécommunications Research ...

SDO sees a mid-level solar flare: Nov. 3

The sun emitted a mid-level solar flare, peaking at 5:40 p.m. EST on Nov. 3, 2014. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. ...

Cosmic rays threaten future deep-space astronaut missions

Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky, concludes a new paper by University ...

Extreme ultraviolet image of a significant solar flare

The sun emitted a significant solar flare on Oct. 19, 2014, peaking at 1:01 a.m. EDT. NASA's Solar Dynamics Observatory, which is always observing the sun, captured this image of the event in extreme ultraviolet wavelength ...

Mangroves protecting corals from climate change

Certain types of corals, invertebrates of the sea that have been on Earth for millions of years, appear to have found a way to survive some of their most destructive threats by attaching to and growing under mangrove roots.

An anomaly in satellite flybys confounds scientists

When space probes, such as Rosetta and Cassini, fly over certain planets and moons in order to gain momentum and travel long distances, their speed changes slightly for an unknown reason. A Spanish researcher has now analysed ...

Image: Rainbow aurora captured from space station

Auroras occur when particle radiation from the Sun hits Earth's upper atmosphere, making it glow in a greenish blue light. ESA astronaut Alexander Gerst has one of our planet's best views of this phenomenon, circling 400 ...
