What the Oldest Fossil on Earth Means for Finding Life on Mars

Scientists have found evidence that life existed on Earth much earlier than previously thought and they say this discovery has implications for life springing up on other planets, particularly Mars. Fossils of microscopic bacteria were discovered in Quebec, Canada in the Nuvvuagittuq Supracrustal Belt, a formation which contains some of the oldest sedimentary rocks in […]

Rapid changes point to origin of ultra-fast black hole ‘burp’

Scientists have made the most detailed observation yet of a black hole outflow, from the active galaxy IRAS 13224-3809. The outflow’s temperature changed on time scales of less than an hour — hundreds of times faster than ever seen before. The rapid fluctuations in the outflow’s temperature also indicated that the outflow was responding to X-ray emissions from the accretion disk, a dense zone of gas and other materials that surrounds the black hole. …
