Meet Icarus, the Most Distant Star Ever Seen

By David Reneke

Astronomers have spotted the most distant star ever seen as well as stunning auroras on Saturn.

More than halfway across the universe, an enormous blue star nicknamed Icarus is the most distant individual star ever seen. Normally it would be much too faint to view, even with the world’s largest telescopes, but through a quirk of nature that tremendously amplifies the star’s feeble glow, astronomers using NASA’s Hubble Space Telescope were able to pinpoint this faraway star and set a new distance record.

Massive Star’s Dying Blast Caught By Pure Chance!

By Dave Reneke

A massive star’s dying blast has been caught by pure chance, and how early moons collided to form today’s Moon.

On 25 June 2016, an international team of 31 astronomers caught a massive star as it died in a titanic explosion deep in space. The blast released in about 40 seconds as much energy as the Sun releases over its entire lifetime, all focused into a tight beam of gamma rays and fortuitously aimed directly toward Earth. The team’s findings provide strong evidence for one of two competing models for how gamma-ray bursters produce their energy.

Bringing the Building Blocks of Life Down to Earth

By David Reneke

Astronomers find more evidence for how life began in Earth, and send a greeting to a red dwarf with two habitable planets.

Where did we come from and how did we get here? How life began on Earth, roughly four billion years ago, is the eternal question and the basis for almost all of cosmology. New results from scientists at McMaster University and the Max Planck Institute for Astronomy suggest a key role for meteorites landing in warm little ponds, delivering essential organic molecules that kick-started the emergence of life in the shape of self-replicating RNA molecules.
