Observations of nitrogen in Earth’s atmosphere by a NASA spacecraft 17 million miles away are giving astronomers fresh clues to how that gas might reveal itself on faraway planets, thus aiding in the search for life.

To find life in the universe, it helps to know what it might look like. If there are organisms on other planets that do not rely wholly on photosynthesis — as some on Earth do not — how might those worlds appear from light-years away?

Planets with volcanic activity are considered better candidates for life than worlds without such heated internal goings-on.
Now, graduate students at the UW have found a way to detect volcanic activity in the atmospheres of faraway planets when they transit, or pass in front of their host stars.

The NASA Astrobiology Institute’s Virtual Planetary Laboratory, based at the University of Washington, has long brought an interdisciplinary approach to the study of planets and search for life outside our solar system. Now, a new NASA initiative inspired by the UW lab is embracing that same team approach to bring together 10 universities and two research institutions in the ongoing search for life on planets around other stars.

Titan, Saturn’s largest moon, has a hazy atmosphere and surface rivers, mountains, lakes and sand dunes. But the dunes and prevailing surface winds don’t point in the same direction. New research from UW astronomer Benjamin Charnay may have solved this mystery.

New research by UW astronomer Rory Barnes and co-authors describes possible planetary systems where a gravitational nudge from one planet with just the right orbital configuration and tilt could have a mild to devastating effect on the orbit and climate of another, possibly habitable world.

Two phenomena known to inhibit the potential habitability of planets — tidal forces and vigorous stellar activity — might instead help chances for life on certain planets orbiting low-mass stars, University of Washington astronomers have found.

Having a companion in old age is good for people — and, it turns out, might extend the chance for life on certain Earth-sized planets in the cosmos as well.

A fluctuating tilt in a planet’s orbit does not preclude the possibility of life, according to new research by astronomers at the University of Washington, Utah’s Weber State University and NASA. In fact, sometimes it helps.

UW astronomers have developed a new method of gauging the atmospheric pressure of exoplanets, or worlds beyond the solar system, by looking for a certain type of molecule. And if there is life out in space, it may one day be revealed by this method.Next Page »
