Were hot, humid summers the key to life's origins?
Oct 08, 2019 (SPX)
"In terms of the history of the planet, how life originated is probably the greatest scientific question we can ask," said Paul Bracher, Ph.D., assistant profes...
Scientists observe formation of individual viruses, a first
Oct 04, 2019 (UPI)

Essential building blocks of DNA - compounds called nucleobases - have been detected for the first time in a simulated environment mimicking gaseous clouds that...
Giant exoplanet around tiny star challenges understanding of how planets form
Sep 30, 2019 (SPX)
Moreover, this new gas giant is on an eccentric orbit, which sug-gests the presence of another massive planet, which may have been ejected from the system in a ...
A planet that should not exist
Sep 27, 2019 (SPX)
The red dwarf GJ 3512 is located 30 light-years from us. Although the star is only about a tenth of the mass of the Sun, it possesses a giant planet - an unexpe...
When dwarf stars give birth to giant planets
Sep 27, 2019 (SPX)

Sep 13, 2019 (SPX)
The star, named HD 163296, is located 330 light years from Earth and formed over the last six million years. It is surrounded by a disc of dust and gas - a so-c...
Research redefines lower limit for planet size habitability
Sep 12, 2019 (SPX)
Of course, in real life, celestial objects that small can't support life because they don't have enough gravity to maintain an atmosphere. But how small is too ...
