Biosignature on Venus likely to be mistake, says new study

Back in September last year, astronomers made a splash when they announced the discovery of phosphine in the atmosphere of Venus, which could be a sign of life. But a new study has found that a different gas could explain the signature detected, and th… Continue reading Biosignature on Venus likely to be mistake, says new study

COVID-19 pandemic triggers largest drop in US life expectancy in decades

A new study from researchers at Princeton University and the University of Southern California, Los Angeles, projects the COVID-19 pandemic to potentially generate the largest single-year decline in US life expectancy since the 1918 influenza pandemic….

Study calculates how lucky we are to have a habitable planet

New research involving the simulation of 100,000 random worlds suggests that chance played a major role in allowing Earth to maintain a habitable environment for the three to four billion years needed for the evolution of complex life.Continue ReadingC… Continue reading Study calculates how lucky we are to have a habitable planet

Missing ingredient for life finally found on a comet

Researchers have detected phosphorus on a comet – thereby completing the grocery list of elements that are essential for life. The discovery was made in data from comet 67P/Churyumov-Gerasimenko by the Rosetta probe a few years ago, strengthening the i… Continue reading Missing ingredient for life finally found on a comet

Europa’s plumes may not originate from subsurface ocean

Jupiter’s moon Europa is a fascinating world, with a global subsurface ocean encased in an icy shell and plumes of water vapor that vent into space. A new study has simulated how these plumes might originate, revealing a surprisingly dynamic ice ball.C… Continue reading Europa’s plumes may not originate from subsurface ocean

Weird molecule found in Titan’s atmosphere hints at complex chemistry

NASA scientists have discovered a “weird” molecule called cyclopropenylidene, or C3H2, in the atmosphere of Saturn’s moon Titan. The simple carbon-based molecule has never been seen in an atmosphere before, and it could give rise to more complex compou… Continue reading Weird molecule found in Titan’s atmosphere hints at complex chemistry

Astronomers isolate stars from which aliens could be observing Earth

Astronomers have identified 1,004 nearby stars from which aliens could detect signs of biological life in Earth’s atmosphere by watching as our planet passes across the disk of the Sun. The study could help provide targets for organizations such as SET… Continue reading Astronomers isolate stars from which aliens could be observing Earth
