You Light Up My Life. Or Do You? Bright Stars and Dark Energy

For decades astronomers have used the Astronomical Magnitude Scale to measure the brightness of stars. But what if they're measuring with an inaccurate ruler? And how could that screw up the quest to understand dark energy? More »

More Evidence that Dark Energy Is Ripping the Universe Apart

At a press conference today, NASA announced new measurements from the Chandra X-Ray Observatory confirm the existence of "dark energy" that is causing the universe to expand - and disintegrate - at a rapid clip.

Heaviest, Farthest Cluster Points Toward Dark Energy

The XMM-Newton space telescope has been really into dark and heavy stuff lately. No, the x-ray observatory didn't find its parents' old Black Sabbath albums — it found the most massive galactic cluster on record, a conglomerate of galaxies weighing more than 1,000 times as much as the Milky Way. The cluster's extreme distance is a puzzling paradox, or it might help prove that the universe is full of mysterious dark energy. More »

Galaxies' Swan Dive May Give New Clues To Dark Energy

One day, we'll use images like this waterfall of galaxies to figure out where to refuel our ships with dark energy. That's because this computer simulation of millions of galaxies flowing towards the red zone, the area with the highest mass, gives some clues to the location and nature of dark energy and dark matter. The image shows a "snapshot" of galaxies in the process of forming large-scale structures, 10 billion years ago. Click through for details. More »
