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.

Census Finds Universe Has Ten Times More Galaxies

By David Reneke

The universe has ten times more galaxies than previously thought, and the Earth may have had more than one moon.

Astronomers using data from the NASA/ESA Hubble Space Telescope and other telescopes have performed an accurate census of the number of galaxies in the universe, and concluded that there are at least 10 times as many galaxies in the observable universe as previously thought. The results have clear implications for our understanding of galaxy formation, and also help solve an ancient astronomical paradox – why is the sky dark at night?
