We Thought They Were Just Stars But They Might Be Inhabited

The Chandra X-ray telescope and other observatories are being used to study stars that could potentially harbor habitable planets. Future observatories will use the data to narrow down the list for possible Earth-like planets to image....

There are many planets in the universe, but very few of them have qualities to support life Taking one celestial body at a time and determining whether it supports life would be slow and inefficient. So, astronomers look for certain...

Astronomer Jill Tarter, Director of the Search for Extraterrestrial Intelligence Institute, highlights the link between recent discoveries of numerous exoplanets and the search for extraterrestrial life.

As we continue our search for earth-like, potentially habitable worlds, we come across an interesting triple-star system called Gliese 667. The smallest of these three stars, Gliese 667 C, is a red dwarf with several planets, one of...

Giada Arney, astrophysicist at NASA’s Goddard Space Flight Center, is looking at the potential for K stars to host habitable worlds. Learn about how stars affect planetary environments and why complex life on early Earth was impossible.

Dr. Clara Sousa-Silva is the co-author on the study about Phosphine on Venus. We ask her some questions from you about the discovery.

What do we know about the planets outside our solar system? NASA planet hunters Jessie Christiansen and Knicole Colon take us beyond...into the exciting world of exoplanets.

The thing to remember here is that finding life on another planet tells us one of very two things...and we will be able to figure out which thing pretty quickly. Either:



1. The life will contain clear signals that it is...

The surface of Venus is completely inhospitable for life: barren, dry, crushed under an...

We now know there are more planets than stars in the galaxy. Many of them are very different from ours. How would we know if any of them had life? Shawn Domagal-Goldman, astrobiologist at NASA’s Goddard Space Flight Center, discusses...

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star's habitable zone, the range of distances where conditions may be just right to allow the presence of...

Astronomers using the Hubble Space Telescope have conducted the first spectroscopic survey of Earth-sized planets in the TRAPPIST-1 system's habitable zone. Hubble reveals that at least the inner five planets do not seem to...

The Mars Atmosphere and Volatile Evolution Mission (MAVEN), set to launch in 2013, will explore the planet's upper atmosphere, ionosphere and interactions with the sun and solar wind. Scientists will use MAVEN data to determine the...

A new study from NASA shows that it may not be possible to make Mars habitable for humans using current technology.
