Earth-like planets around small stars likely have protective magnetic fields, aiding chance for life
Earth-like planets orbiting close to small stars probably have magnetic fields that protect them from stellar radiation and help maintain surface conditions that could be conducive to life, according to research from astronomers ...
Rock samples from Western US teach how to hunt for life on Mars
The search for life beyond Earth is one of the grandest endeavors in the history of humankind—a quest that could transform our understanding of our universe both scientifically and spiritually.
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. ...
What types of nucleic acids existed before RNA and DNA?
Structure generation software allows scientists to begin exploring the types of nucleic acids that could have existed before, alongside, or indeed instead of, ribonucleic acid (RNA) and DNA.
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 ...
