Researchers in Wisconsin are searching for and testing new chemical recipes for the origin of life. Such recipes for life may be common in the universe.
Scientific arguments suggest that alien civilizations should be common in our galaxy. If so, where is everybody? That question is known as the Fermi paradox.
Several new reports and discoveries, including 5 new papers, support the possibility of life beyond Earth. Are we getting closer to finding alien life?
More about the mind-boggling new studies suggesting that there could be many parallel universes beyond our own, where life is able to flourish.
Evidence of life processes found in fossils in 3.5-billion-year-old rocks. Scientists say this work suggests life in our universe is widespread.
Astronomers propose a search for a theoretical kind of planet known as carbon planets, aka diamond planets. They say such planets might have been habitable.
NASA's Webb telescope looked at the sub-Neptune exoplanet K2-18 b. It found methane, carbon dioxide, a possible ocean, and even ... maybe ... a biosignature.
Is alien life purple? Researchers from Cornell University think that as far as alien worlds go, purple may be the new green.
A new study of Cassini data has revealed bacteria-sized particles in the plumes of Saturn's ocean moon Enceladus. Could they be evidence of microbial life?
Seahorses look like a blend of different animals, making them mysterious and efficient. With no stomach, they have to eat nearly constantly.
The threat of supernovas to life on Earth is due to their intense radiation. Fortunately, they'd have to be fairly close to affect Earth.
A new study analyzed the motions of satellite galaxy pairs around a large galaxy group and showed the universe may be younger than the standard model predicts.
Do the plumes on Enceladus contain evidence of life from the moon's ocean? A new study shows that amino acids could survive and be detectable by spacecraft.
Researchers at Johns Hopkins are simulating haze on water worlds. The haze muddles observations but can also help determine if an exoplanet is habitable.
Researchers in the U.K. said in a new study that 'bouncing comets' in some planetary systems could deliver prebiotic molecules needed for life to young planets.
In 2018, the International Astronomical Union voted to rename Hubble's law as the Hubble–Lemaître law to share credit between Edwin Hubble and Georges Lemaître.
Could there once have been a network of life-supporting rivers for Mars? A study from Penn State suggests Mars' rivers might once have been common.
Bats might be spooky, but they pollinate flowers, control insect pests, and have inspired scientists to improve human lives in many ways.
Researchers at the Planetary Science Institute said that an ancient mud lake on Mars would be an ideal place to search for evidence of ancient microbial life.
Researchers in the U.S. and Japan have developed a new AI technique that can determine if there is evidence for past or present life, or not, with 90% accuracy.
