Spectrum of life: Nonphotosynthetic pigments could be biosignatures of life on other worlds
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 ...
How much contamination is OK on Mars 2020 rover?
When the Mars 2020 rover arrives on the Red Planet, one of its primary mission goals will be to select and preserve samples that would eventually make it back to Earth for scientific study. Rather than seeking to eliminate ...
Atmospheric signs of volcanic activity could aid search for life
Planets with volcanic activity are considered better candidates for life than worlds without such heated internal goings-on.
Mini-Neptunes might host life under right conditions
M-dwarfs, which are cooler than our sun, have habitable zones closer to the stars. As such, any habitable planets orbiting these stars would transit frequently, making the chances of discovery better.
Ether compounds could work like DNA on oily worlds
In the search for life beyond Earth, scientists have justifiably focused on water because all biology as we know it requires this fluid. A wild card, however, is whether alternative liquids can also suffice as life-enablers. ...
Iron-rich rocks could could hold signs of life
A robotic mission's search for life on Mars may seem worlds away from human scientists wandering around hot springs in Yellowstone National Park. But a study of the Yellowstone hot springs has revealed new clues about how ...
Some potentially habitable planets began as gaseous, Neptune-like worlds
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 ...
Life needs an atmosphere, but how much is too much?
How much atmosphere is too much for life? As scientists discover more super-Earths and mini-Neptunes, the question becomes more relevant.
Scientists identify mineral that destroys organic compounds, with implications for Mars Curiosity mission
Scientists have discovered that the mineral jarosite breaks down organic compounds when it is flash-heated, with implications for Mars research.
Potential signs of ancient life in Mars rover photos
A careful study of images taken by the NASA rover Curiosity has revealed intriguing similarities between ancient sedimentary rocks on Mars and structures shaped by microbes on Earth. The findings suggest, but do not prove, ...
