The results are great news for humanity's first test of its planetary defense system.

Previously unpublished notes by Galileo that were checked in the aftermath of the forgery's discovery indicate that he was the true author of a treatise titled the "Considerazioni Astronomiche di Alimberto Mauri" — Italian for the "Astronomical Considerations of Alimberto Mauri" — which was published in 1604.

The unusual colors are the result of numerous factors, including water chemistry, depth and inhabiting wildlife. The three lakes are Lake Shala, which has a deep blue hue; Lake Abijatta, which is green in color; and Lake Langano, which has a sandy-yellow hue similar to the surrounding land. The lakes are located in Ethiopia's Great Rift Valley, around 124 miles (200 kilometers) south of the capital, Addis Ababa.

The new theory comes from a climate modeling study that simulated hydrogen-consuming, methane-producing microbes living on Mars roughly 3.7 billion years ago.

Around 66 million years ago, an asteroid approximately 6.2 miles (10 kilometers) across smashed into Earth near the Yucatan Peninsula, plunging the planet into darkness and causing a mass extinction that wiped out 80% of animal life — including all the non-avian dinosaurs.

The DNA is the oldest ever discovered from seafloor sediments, a new study shows. Scientists accidentally collected the unusual genetic samples, known as sedimentary ancient DNA or sedaDNA, up to 584 feet (178 meters) beneath the seafloor as part of a 2019 survey led by the International Ocean Discovery Program in the Scotia Sea north of mainland Antarctica.
