*New date for first life on Earth
New evidence shows life began on Earth at least 3.77 billion years ago – that’s some 300 million years earlier than previously thought -- and at a time when Mars was also a warm wet world. Scientists discovered the tiny filaments and tubes formed by bacteria on the shores of Canada’s Hudson Bay..
*Star clusters discovery could upset the astronomical applecart
Astronomers have discovered multiple generations of stars in a single star cluster. The discovery adds to a growing body of evidence that not all the stars in a single cluster were formed at the same time.
