Not a “firewall”—and the nature of the universe depends on it, physicist explains.

A recent and famous image from deep space marks the first time we’ve seen a forming planetary system, according to a study by University of Toronto astrophysicists

New study suggests that iconic structures more aptly named the Pillars of Destruction

Berkeley Lab astrophysicist David Schlegel weighs in on Hollywood science and untapped concepts for future sci-fi flicks.

Human-caused climate change, ocean acidification and species extinctions may eventually threaten the collapse of civilization, according to some scientists, while other people argue that for political or economic reasons we should allow industrial development to continue without restrictions.

Using extremely faint light from galaxies 10.8-billion light years away, scientists have created one of the most complete, three-dimensional maps of a slice of the adolescent universe. The map shows a web of hydrogen gas that varies from low to high density at a time when the universe was made of a fraction of the dark matter we see today.

Soon, the growing capability of your smartphone could be harnessed to detect cosmic rays in much the same way as high-end, multimillion-dollar observatories.

In the beginning, or at least following the Big Bang more than 14 billion years ago, there was hydrogen, some helium and a little bit of lithium. A grand total of three elements.

Magnetic reconnection in the Earth and sun's atmospheres can trigger geomagnetic storms that disrupt cell phone service, damage satellites and blackout power grids. Understanding how reconnection transforms magnetic energy into explosive particle energy has been a major unsolved problem in plasma astrophysics.
