Geneticists around the world are studying 100,000 coronavirus genomes – sampled from Covid-19 patients in over 100 countries – to try to understand how the virus is mutating, What science has learned.
Brilliant Venus, in and of itself, is worth getting up for, but the tantalizingly close encounter of Venus with the bright star Regulus won’t happen again for another 8 years. Start watching them now!
Water-vapor geysers erupt from cracks at the south pole of Saturn’s moon Enceladus. Scientists using Cassini data now have evidence for fresh ice at the moon’s north pole, too. Could it be more geysers for this fascinating ice moon?
Infrared images of Enceladus from Cassini, showing evidence for resurfacing by fresh ice deposits at the north pole of the moon. The famous tiger stripes fissures can also be seen at the south pole.
