Building blocks of life can form long before stars

An international team of scientists have shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh conditions that govern chemistry in space.

Preparing for a human mission to Mars

Future human missions to Mars depend on field research in an environment similar to that of Mars. It will enable the evaluation of operational concepts and optimization of strategies. The goals and results of the AMADEE-18 ...

Assessing the habitability of planets around old red dwarfs

A new study using data from NASA's Chandra X-ray Observatory and Hubble Space Telescope gives new insight into an important question: how habitable are planets that orbit the most common type of stars in the Galaxy? The target ...

A Subterranean ecosystem in the Chicxulub crater

A new study reveals that the Chicxulub impact crater and its hydrothermal system hosted a subterranean ecosystem that could provide a glimpse of Earth's primordial life.

Study shows comets impacted start of life on earth

The Big Bang may have started the universe, but it's likely that littler bangs played a key role in life on Earth, say Albion College Physics Professor Nicolle Zellner and Chemistry Professor Vanessa McCaffrey. They (along ...

The implications of signs of life on Venus?

The planet Venus has arguably remained less captivating than, say, the legendary tennis star or, for that matter, the women's razor blade company—both of those Venuses have at least enjoyed ample airtime on cable TV.

OSIRIS-REx mission researchers detail history of asteroid Bennu

NASA's OSIRIS-REx spacecraft mission, launched on Sept. 8, 2016, is the first U.S. mission designed to retrieve a pristine sample of an asteroid and return it to Earth for further study. The mission's target is Bennu, a carbon-rich ...

Some planets may be better for life than Earth

Earth is not necessarily the best planet in the universe. Researchers have identified two dozen planets outside our solar system that may have conditions more suitable for life than our own. Some of these orbit stars that ...

Titan's lakes can stratify like those on Earth

Lakes on Saturn's moon Titan, composed of methane, ethane, and nitrogen rather than water, experience density driven stratification, forming layers similar to lakes on Earth. However, whereas lakes on Earth stratify in response ...

Could life exist deep underground on Mars?

Recent science missions and results are bringing the search for life closer to home, and scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) and the Florida Institute of Technology (FIT) may have figured ...
