No need for extrasolar delivery by comet: Nitrogen fingerprint in biomolecules could be from early Sun
Chemical fingerprints of the element nitrogen vary by extremes in materials from the molecules of life to the solar wind to interstellar dust. Ideas for how this great variety came about have included alien molecules shuttled ...
One of the four Cluster satellites has shifted its orbit to ensure a safe reentry when the time comes, as well as providing a rare opportunity to study how a satellite's exhaust plume interacts with the solar wind.
This week's spectacular glowing auroras in the night sky further south than usual highlighted the effect that 'space weather' can have on Earth.
Early discoveries by NASA's newest Mars orbiter are starting to reveal key features about the loss of the planet's atmosphere to space over time.
