FORBES - Carbon Dioxide is often vilified as a bugaboo greenhouse gas. But its presence here on early earth is likely one of the reasons we are here to talk about it. Carbon dioxide, or CO2, was likely needed in large quantities in earth’s early atmosphere to raise temperatures sufficiently to enable the onset of...
THE U.S. SUN - Scientists have created a 3D illustration charting a list of nearby stars that may be hosting "habitable" alien worlds. They used data from NASA's Chandra X-ray Observatory to identify these planets. It involved finding stars that are close enough to Earth that we could use future telescopes to take images of...
LIVE SCIENCE - NASA's Chandra X-ray space telescope has created a three-dimensional map of stars close to the sun that may help astronomers search for alien planets that could host life. The map created by Chandra — which just celebrated 25 years in orbit but is facing a troubling budget crunch — could inform scientists...
ASTRONOMY - In a new study published in The Astrophysical Journal, astronomers propose looking for greenhouse gases in the atmospheres of exoplanets using tools like the James Webb Space Telescope (JWST). But rather than searching for an advanced species suffering the consequences of climate change, such gases might be a sign of something else: terraforming...
ANCIENT ORIGINS - While we have yet to identify life on any other planet or anywhere else in space, a new study has revealed the telltale signs which could indicate a planet being inhabited. Researchers at the University of California, Riverside (UCR) discovered that greenhouse gases, much like the ones emitted by our very own...
IFLSCIENCE - There may come a point (perhaps for humans, perhaps not) where a civilization may wish to terraform a planet in their Solar System or beyond. Perhaps an environmental disaster was looming on their planet, or they spotted a nearby neighbor planet that looked like – with a few finishing touches – it could...
EARTH.COM - The search for extraterrestrial life has captivated our imaginations for centuries. Now, a study from the University of California, Riverside (UCR) suggests a tantalizing possibility: we may be able to detect alien activity and civilizations by identifying artificial greenhouse gases they use to terraform planets. What is terraforming? Terraforming, a concept popular in...
THE DAILY MAIL - Alien life has yet to be found in space, but a new study has uncovered 'telltale' signs of an inhabited planet. Researchers at the University of California, Riverside (UCR) discovered that greenhouse gases, like those emitted on Earth, would mean a distant world had been terraformed - or artificially altered. Signatures...
THE INDEPENDENT UK - Scientists have identified a set of greenhouse gasses which could be used as a marker to look for advanced alien civilizations with the potential to transform entire planets to make them habitable. While greenhouse gasses cause global warming and must be controlled on Earth, they may be used intentionally to make...
EXTREME TECH - Until someone invents warp drive, the only way we can inspect distant exoplanets is with a powerful telescope. However, even the most capable telescopes can only catch faint glimmers from exoplanets. In a new study, scientists from the University of California, Riverside, lay out a method of detecting potential alien activity, and...
