A new result from ESO’s HARPS planet finder shows that rocky planets not much bigger than Earth are very common in the habitable zones around faint red stars. The international team estimates that there are tens of billions of such planets in the Milky Way galaxy alone, and probably about one hundred in the Sun’s […]
A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea.
Scientists at the Naval Research Laboratory have identified a new mode of coupling between the stratosphere — which can drive variations at the summer mesopause — and the ionosphere, thereby establishing a new means where changes in the stratosphere can impact space weather. This research appeared in the January 6th, 2012 issue of Geophysical Research […]
