On April 25 and 26, 2019, NSF’s Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered two new gravitational waves, the ripples in space-time predicted by Albert Einstein. The first was from a neutron star crashing into another neutron star 500 million light-years away, and the second was from a neutron star gobbled up by a black hole 1.2 billion light-years away. If confirmed, the second event...

Astronomers developed a mosaic of the distant Universe -- called the Hubble Legacy Field -- that documents 16 years of observations from the NASA/ESA Hubble Space Telescope. The image contains nearly 265,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the Big Bang. The new set of Hubble images, created from nearly 7,500 individual exposures, is the first in a series of Hubble Legacy Field images. Image credit: NASA / ESA / G. Illingworth & D.
