Woot! Spring break is here and it's time to take a trip - space style. This spring break, I'm shadowing Columbia astronomy professors and students to see the night sky from Kitt Peak, Arizona, a mecca of astronomy observatories. Check it out.

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.

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.

To make the find, astronomers developed a big new array of superconducting detectors for a telescope at the South Pole, which spotted characteristic patterns in ancient light left over from the Big Bang.

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.

To celebrate the Hubble Space Telescope's 24th year in orbit, astronomers set their sights on NGC 2174, the Monkey Head Nebula. Young stars are sculpting gas and dust of this Orion constellation nebula.

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.
17 March 2014, 10:45 AM ET
Moving masses generate waves of gravitational radiation that stretch and squeeze space-time.
17 March 2014, 10:45 AM ET
Artist's concepts illustrate how gravitational waves might spread through the universe.

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.
17 March 2014, 10:45 AM ET
It has been 50 years since two scientists found landmark evidence for the Big Bang theory. Robert Wilson and Arno Penzias were using a large horn antenna at Bell Labs in New Jersey to gaze into the Milky Way.

On its final orbit In 2017, NASA's Cassini probe will fly between the inner edge of the D ring and the upper atmosphere of the gas giant. It will also fly though an Enceladus plume in the next few years.
