The fossilized remains of methane-cycling microbes have been found in exposed sedimentary seafloor rocks in South Africa. These microbes, dating back 3.42 billion years, could extend the fossil record back to when life first began on Earth. Plus, teenage exoplanets orbit sibling stars, and gamma-ray bursts happen on schedule.
New high-resolution images captured by the SOFIA airborne telescope have given scientists the first clear view of a massive star-forming region here in the Milky Way, including an expanding bubble of gas. Plus, finding Earth-like exoplanets, detecting life on Earth, and this week’s What’s Up, featuring the Messier Catalogue.
New research shows that our galaxy was already in place prior to a major collision with a dwarf galaxy ten billion years ago. Plus, meteor showers, fast radio bursts, tardigrades, climate change, and a science review of Godzilla vs. Kong. No. Really!
On March 5, 2021, three separate, large earthquakes occurred within hours of each other near New Zealand, and all three produced a tsunami. The resulting changes in wave height were recorded with special buoys. Plus, a radar blackout at Mars, a giant planet growing, small galaxies in the early Universe, and what even is a day?
The biggest mass extinction event on Earth occurred at the end of the Permian period, resulting in the extinction of 95% of marine life and 80% of terrestrial life. Now, scientists have found that the terrestrial portion of the event lasted nearly ten times as long as the ocean version. Plus, a spaghettified star, the search for Moon Trees, all about Mars, and new works on dark matter and dark energy.
Today’s news examines many of the ways in which scientists are trying to understand Earth’s atmosphere as well as the atmospheres of exoplanets, mostly in the hopes of figuring out the best way to tell if there is life on another world. Plus, sixty years of fusion power and this week’s What’s Up.
