Sun's rotating 'magnet' pulls lightning towards UK
(Phys.org) —The Sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper ...
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 ...
Study finds a barrage of small impacts likely erased much of the Earth's primordial atmosphere
Today's atmosphere likely bears little trace of its primordial self: Geochemical evidence suggests that Earth's atmosphere may have been completely obliterated at least twice since its formation more than ...
'Mystery goo' on shorebirds is nonpetroleum fat or oil, scientists say

What is the upper limit for massive stars?
Yesterday I mentioned that hypernovae (super-supernovae) are the result of the explosion of a star that's about as massive as a star can be (about 150-200 solar masses). But how exactly do we know that t ...
Warming Earth heading for hottest year on record (Update)
Earth is on pace to tie or even break the mark for the hottest year on record, U.S. meteorologists say.
What does the next generation telescope need to detect life?
Almost 2,000 extrasolar planets have been discovered to date and this number is constantly increasing. Yet, we still know little about these alien worlds, especially their atmospheres. The atmospheres of ...
