Astronomers identify a giant cluster of galaxies 5.7 billion light-years from Earth. At its core new stars are being formed at a rate that could explain how supermassive black holes govern a galaxy's growth.
Researchers studying the star system Kepler-30, which is 10,000 light-years from Earth, found that its three known worlds all orbit in the same plane, lined up with the rotation of the star — just like the planets in our own solar system.
Researchers say they've created a jellyfish that's one part artificial, one part biological. Creation of the 'pseudo organism' could yield new insights into medical research – or even cleaning up environmental pollution.
