A Southwest Research Institute scientist modeled the atmosphere of Mars to help determine that salty pockets of water present on the Red Planet are likely not habitable by life as we know it on Earth. A team that also included scientists from Universities Space Research Association (USRA) and the University of Arkansas helped allay planetary protection concerns about contaminating potential Martian…

Two (potentially) exciting new exoplanet discoveries
Scientists just announced 2 new exciting updates about exoplanets. One is a potentially habitable world similar in size and temperature to Earth. The other is a possible new planet – possibly with rings – orbiting the closest star to our sun, Proxima Centauri.

Will SETI 2.0 lead to a discovery of intelligent aliens?
2020 has been an exciting year so far for SETI – the search for extraterrestrial life – in terms of new technological developments and strategies. Source: https://earthsky.org/space/seti-breakthrough-listen-new-technologies-and-strategies…
Was Mercury once habitable?
As unlikely as it may sound, Mercury may have once been able to support subsurface microscopic life, according to a new study from the Planetary Science Institute. Source: https://earthsky.org/space/mercury-habitability-chaotic-terrain-messenger-astrobiology…
Will we soon see potentially habitable exoplanets more clearly?
Because stars are so much brighter than their planets, we’ve barely begun to glimpse distant exoplanets, or planets orbiting distant stars. Now a new technology promises to provide better imaging of these potentially habitable exoworlds. Source: https://earthsky.org/space/exoplanets-direct-imaging-potential-habitability…
Could K2-18b be habitable after all?
A new study by researchers at Cambridge University suggests that the giant exoplanet K2-18b – a mini-Neptune – may be more potentially habitable than previously thought. Source: https://earthsky.org/space/k2-18b-mini-neptune-exoplanets-habitability…
Using radio waves to discover and study exoplanets
A new study from researchers in the Netherlands shows how scientists can detect exoplanets orbiting red dwarf stars, and learn about their environments, from the radio waves generated by auroras on those worlds. Source: https://earthsky.org/space/exoplanets-red-dwarfs-radio-waves-auroras…
Goldilocks stars best for alien life?
A new research study suggests that K-type dwarf stars (smaller and cooler than our sun) are the best place to search for alien life. These stars are not too hot, not too cool, and not too violent for life to evolve. Source: https://earthsky.org/space/goldilocks-stars-g-k-dwarfs-best-for-alien-life…
NASA Has Discovered an Earth-Sized World in a Star’s Habitable Zone
“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 liquid water on the surface,” reports NASA’s Goddard Space Flight Center: Scientists confirmed the find, called TOI 700 d, using NASA’s Spitzer Space Telescope and have modeled the planet’s…
A new tool for ‘weighing’ unseen planets
A new instrument funded by NASA and the National Science Foundation called NEID (pronounced “NOO-id”; sounds like “fluid”) will help scientists measure the masses of planets outside our solar system—exoplanets—by observing the gravitational pull they exert on their parent stars. That information can help reveal a planet’s composition, one critical aspect in determining its potential habitability. Source: https://phys.org/news/2020-01-tool-unseen-planets.html…
