Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of ancient life on the red planet may not be sensitive enough to make accurate assessments, according to an ...
Aided by microbes found in the subarctic conditions of Canada’s Hudson Bay, an international team – including researchers from Portugal’s Instituto Superior de Agronomia and Técnico, Canada’s Universi...
It’s hard to imagine a more inhospitable world than our closest planetary neighbor. With an atmosphere thick with carbon dioxide, and a surface hot enough to melt lead, Venus is a scorched and suffoca...
Our solar system is teeming with simple carbon-based molecules, the basic building blocks of life. If the conditions are right, these simple molecules can go on to form more complex, biologically inte...
The National Science Foundation’s Green Bank Telescope (GBT) will join in the most powerful, comprehensive, and intensive scientific search ever for signs of intelligent life in the Universe. The inte...
03 July 2014 — Mysteries about controversial signals coming from a dwarf star considered to be a prime target in the search for extraterrestrial life now have been solved in research led by scientists...
This meeting aims to address the life cycle of dust in the Universe, which covers the formation, evolution and destruction of dust in a range of environments, ranging from the smallest to the largest ...
Life arose on Earth sometime in the first few hundred million years after the young planet had cooled to the point that it could support water-based organisms on its surface. The early emergence of li...
Processes taking place in outer space, and not on Earth, are likely to have led to the biological molecules found exclusively in either a left-handed or right-handed form. That is the conclusion drawn...
The homochirality of the molecules of life has been a vexing problem with no generally accepted solution to date. Since a racemic mixture of chiral nucleotides frustrates the extension and replication...
Astronomically, there are viable mechanisms for distributing organic material throughout the Milky Way. Biologically, the destructive effects of ultraviolet light and cosmic rays means that the majori...
An analysis is made of the manner in which the cosmic ray intensity at Earth has varied over its existence and its possible relevance to both the origin and the evolution of life. Much of the analysis...
Whether life exists elsewhere in our universe is a longstanding mystery. But for some scientists, there’s another interesting question: could there be life in a universe significantly different from o...
Scientists in California have discovered a new way that stars explode, in research funded by the National Science Foundation (NSF).The discovery hinges on an unusual explosion in the galaxy NGC 1821, ...
Humans might not be walking on Earth today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes, NASA-funded research has found.
