Empty Sky? Not To Hubble’s Eye

Rarely has so much been accomplished by staring into empty space. But that’s exactly what astronomers have been doing with the Hubble Space Telescope in the Frontier Fields program since 2012. It works like this: while Hubble keeps one eye  (camera) on a distant galaxy cluster, it aims another at an adjacent but empty field…

Hubble Smashes Cosmic Distance Record

We have a new record! Astronomers have pushed the Hubble Space Telescope to the limit and uncovered a new galaxy so far away, it’s still in the process of formation only 400 million years after the universe began in the Big Bang. Located 13.4 billion light years from Earth, Yale researchers led an international team of…

Galactic Snacker Naps After Dining On Stars

I sense a real interest about the gravitational wave discovery today even among people who don’t usually pay attention to science news. I think we’re all amazed on at least two fronts: that Einstein made the prediction so long ago and that such a huge discovery still remained to be made. At times, we seem to…

Astronomers Discover Brightest Galaxy In The Universe

Our Milky Way is a substantial galaxy containing some 300 billion stars, over a thousand star clusters, tens of thousands of star-forming gas clouds and possibly up to 100 billion planets. All swirling around in pizza-like disk 100,000 light years across. It’s big enough and bright enough to see dimly with the naked eye from…

Hubble Sees Ghosts Of Quasars Past Etched In Green Whorls

Astronomers using the Hubble Space Telescope have discovered strands of ghostly green goo whirling around inside galaxies that once blazed with brilliant quasars. The looped structures are actually made of the gases oxygen, helium, neon, nitrogen and sulfur. Such huge structures glow for a reason – they’re powered by the light an ancient quasar. Quasars…
