Variations in the amount of oxygen in Earth's atmosphere significantly altered global climate throughout the planet's history. Efforts to reconstruct past climates must include this previously overlooked factor, a new University ...
Expedition 43 Flight Engineer Samantha Cristoforetti of the European Space Agency (ESA) photographed the giant solar arrays on the International Space Station on Feb. 12, 2015.
ESA astronaut Samantha Cristoforetti took these images from the International Space Station during her six-month mission. The Progress cargo ship and Soyuz crew spacecraft reflect sunlight as our star sets behind Earth.
Apart from their style, sunglasses have changed very little in the last few decades. Photochromic lenses that change from clear to tinted in sunlight were a big breakthrough.
(Phys.org)—Cyanobacteria, bacteria that obtain their energy through photosynthesis, are of considerable interest as bio-factories, organisms that could be harnessed to generate a range of industrially useful products.
The European Space Agency says that its scientists are taking a bit of a break after working for four days around the clock since the pioneering lander Philae touched down on a comet.
Europe's Philae lander is doing well and has succeeded in planting a thermometer in the comet where it touched down this week, the European Space Agency said Friday.
If you missed April's total eclipse of the moon, now's your chance. But you'll need to get up early.
Capturing sunlight reflected off the Earth's surface and bounced off a cloud back to the Earth is an effective measure of surface reflectivity—or surface albedo, the measure of how mirror-like the Earth's surface is. Researchers ...
The vast reservoir of carbon stored in Arctic permafrost is gradually being converted to carbon dioxide (CO2) after entering the freshwater system in a process thought to be controlled largely by microbial activity.
