Microbes Survive a Mixed Bag of Mars ‘Biocidals’
Topic: Extreme Life
For the first time, scientists find that microbes from Earth can survive and grow even in the mix of drastically low pressure, freezing temperatures and oxygen-starved conditions seen on Mars.

Habitable Binary Star Systems
Topic: Cosmic Evolution
Habitable planets hoping to see a double sunset stand the best chance when orbiting twin stars that are close together.

Swansong Biospheres
Topic: Earth
Billions of years from now, life on Earth will be extinguished when the Sun becomes a Red Giant star. New research determines the last places life will exist before our planet is sterilized.

Storms in the Machine
Topic: Climate
NASA researchers are constructing a statistical typhoon model that can quickly generate millions of synthetic typhoons from birth through termination. Their work could provide new details about the climate of Earth, and what the future may hold for life on our planet.

At Last, How Many Alien Civilizations are There?
Topic: Alien Life
Frank Drake’s famous equation for estimating alien life has been altered by one scientist to create the “Statistical Drake Equation”. The results provide good news for the SETI community.

Do Aliens Use Hairspray?
Topic: Alien Life
Chemicals such as those found in hairspray might one day serve as signs that aliens have reshaped distant worlds, researchers say.

A 3.45-Million-Year-Old Diet
Topic: Geology
Researchers are providing new information about the ‘diet’ of microorganisms on the early Earth. By studying 3.45-billion-year-old rocks, the team uncovered clues about ancient microbial metabolism.

Life on Earth’s Ceiling
Topic: Extreme Life
Studies have previously discovered microbes in the upper atmosphere, but little is known about the diversity of life up there. New research aims to take a census at the top of the sky.

Colors of ExoEarths Could Indicate Habitability
Topic: Alien Life
When direct detection of Earth-like planets becomes possible, scientists want to be able to easily characterize these planets and see which ones might be suitable for alien life. A new technique shows how the unique colors of particular environments known to harbor extremophile life on Earth can be detected remotely.

How Hot are Super-Earths?
Topic: Cosmic Evolution
A new study suggests that rocky super-Earths might cool down very slowly after their formation, making them hotter than previously thought. The research could have implications in understanding how "Earth-like" these planets truly are.
