ESO’s Latest Dramatic Landscape

by Shannon Hall August 25, 2014

The universe is stunning. Images from even the most modest telescopes can unveil its brilliant beauty. But couple that with a profound reason — our ability to question and understand the physical laws that dominate that brilliant beauty — and the image transforms into something much more spectacular. Take ESO’s latest image of two dramatic star […]

The Making of the Pillars of Creation

by David Dickinson June 26, 2014

It’s one of the most iconic images of the modern Space Age. In 1995, the Hubble Space Telescope team released an image of towering columns of gas and dust that contained newborn stars in the midst of formation. Dubbed the “Pillars of Creation,” these light-years long tendrils captivated the public imagination and now grace everything […]

Powerful Starbursts in Dwarf Galaxies Helped Shape the Early Universe, a New Study Suggests

by Shannon Hall June 19, 2014

Massive galaxies in the early Universe formed stars at a much faster clip than they do today — creating the equivalent of a thousand new suns per year. This rate reached its peak 3 billion years after the Big Bang, and by 6 billion years, galaxies had created most of their stars. New observations from […]

Early Supermassive Black Holes First Formed as Twins

by Jason Major November 6, 2013

It’s one of the puzzles of cosmology and stellar evolution: how did supermassive black holes get so… well, supermassive… in the early Universe, when seemingly not enough time had yet passed for them to accumulate their mass through steady accretion processes alone? It takes a while to eat up a billion solar masses’ worth of matter, […]

The Great Galactic Turn-Off

by Tammy Plotner August 1, 2013

Are you ready for a new galactic puzzle? Then let’s start with some clues. It has been long assumed that some galaxies reach a point in their evolution when star formation stops. In the distant past, these saturated galaxies appeared smaller than those formed more recently. This is what baffles astronomers. Why do some galaxies […]
