Tiny vibrations could reveal extraterrestrial life




Looking for life on other planets is not straightforward. Usually, chemical detection is used, but such tests are limited in scope and might be completely irrelevant to esoteric alien biology. Motion is a trait of all life, but detecting the tiny movements of microorganisms requires incredible sensitivity. Now, Swiss scientists say they have developed an […]

How long can our technological civilization last?




By combining the Earth-based science of sustainability with the space-oriented field of astrobiology, two astrophysicists are attempting to answer questions about humanity’s future in the broadest astronomical context. In their paper, which appears in the journalAnthropocene, Adam Frank and Woodruff Sullivan (both from the University of Rochester) propose that climate change, ocean acidification, and species […]

Europa report: moon’s ocean currents make life possible




A team of scientists who have been modeling the subsurface ocean on Jupiter’s moon Europa say that the ocean’s deep currents and circulation patterns likely create heat and energy transfers capable of sustaining biological life. The researchers behind the exciting new finding, from the University of Texas at Austin, the Georgia Institute of Technology, and […]

First discovery of extraterrestrial life will likely be around a white dwarf star, say astrophysicists




Detecting extraterrestrial life from tell-tale atmospheric signatures is much easier to do when the planet under observation is orbiting a dying star, say Harvard Smithsonian scientists who believe that white dwarf systems are the best candidates for catching our first glimpse of life outside our solar system. Explaining their reasoning in Monthly Notices of the […]

Springtime on Earth II




The Kepler space telescope has identified a large, rocky exoplanet with a surface temperature of about 22 degrees Celsius (72 degrees F, comparable to a comfortable spring day on Earth). The discovery represents the first detection of a possibly habitable world in orbit around a star much like our own Sun. The team behind the […]

Scientists mull polarized light detection from alien life-forms




Like life on Earth, extraterrestrial life should create an environment with a large amount of molecules that favor one kind of handedness, and now, scientists at the National Institute of Standards and Technology (NIST) believe we may be able to identify life-harboring planets by looking for left- (or right-) handed reflected light from these planets. […]
