Mini-sats: The trick to spying Earth-bound asteroids?
NASA is supposed to begin nonstop screening by 2020 for all asteroids that could pose a threat to Earth. Some astronomers now think the only way to affordably meet that deadline is by using mini-satellites

Galaxy cluster creates ‘magnifying glass’ in space
A massive galaxy’s gravity is so strong that it bends light, creating a “lens” in space. This natural magnifying glass is giving astronomers a rare view of a supernova on the other side of the universe.

‘Smart’ windows could save energy
Tiny chemical droplets in a liquid sandwiched between panes of glass turn cloudy when they warm up. This will block some sunlight and potentially save on air conditioning bills.

Fast sea level rise is a very recent change
Sea levels have been rising for more than a century. But that rise is now speeding up. That suggests that what is driving the rise — climate change — also has increased dramatically in recent years.
