Scientists have long suspected that volcanoes played a huge role in the evolution of cloud-shrouded Venus, the second planet from the sun. Images from Europe's Venus Express orbiter show that volcanic eruptions may not just be a thing from the past.

Amazon CEO Jeff Bezos' private expedition that recovered NASA moon rocket engines from the ocean floor was honored by a venerable group of explorers, including one of the astronauts who rode to space atop those very same engines.

The first direct evidence of cosmic inflation — a rapid period of expansion that occurred a fraction of a second after the Big Bang — could also help support the idea that this universe exists in a multiverse, scientists suggest.
17 March 2014, 08:49 PM ET
The find suggests that space-time really did expand at many times the speed of light in the first few tiny fractions of a second after the Big Bang, as predicted by the theory of cosmic inflation, researchers say.

New information from NASA's MESSENGER solves the contradiction between the evidence of shrinking on the planet's crust and the models for heat loss in its core.

A rare cosmic sight will grace the night sky this week when the huge the asteroid Erigone passes in front of the bright star Regulus, as seen from Earth, on the night of March 19 and 20.

The Nobel laureate talks about the apparent detection of gravitational wave signatures in the cosmic microwave background radiation, as well as what it was like to spot the CMB in 1964, putting the Big Bang theory on solid ground.

A new discovery reveals much about the expansion of the early universe by studying gravitational waves.
17 March 2014, 11:25 AM ET
Evidence that the universe rapidly expanded in its first few nanoseconds has been found by an instrument in Antarctica: Gravitational waves, which have long eluded astronomers, were spotted, supporting this cosmic inflation model.
17 March 2014, 10:45 AM ET
Gravitational waves are the "smoking gun" of the Big Bang. Predicted by Albert Einstein's theory of general relativity in 1916, a massive object like Earth distorts space-time around it like a bowling ball dropped on a trampoline.

Inflation is the mysterious force that blew up the scale of the infant universe from sub-microscopic to gargantuan in a fraction of a second.
17 March 2014, 10:45 AM ET
Astronomers have found the first direct evidence of cosmic inflation, the theorized dramatic expansion of the universe that put the "bang" in the Big Bang 13.8 billion years ago. The find also confirms the existence of gravitational waves.
