Astronomy Cast Ep. 408: Universe Cannibalism Welcome to Astronomy Cast, our weekly facts based journey through the cosmos. Where we help you understand not only what we know, but how we know what we know. My name is Fraser Cain, I'm the publisher of Universe Today. With me is Dr. Pamela Gay, a professor at Southern Illinois University Edwardsville, and the director of Cosmoquest. Hi Pamela, how are you doing? We've talked about stellar cannibalism and galactic cannibalism, but now it's time to take this concept to its logical extreme - universe cannibalism. In the multiverse theory of physics we live in just one of a vast range of universes which might interact with each other. Let's look for the evidence.

The close call experienced by the ExoMars Trace Gas Orbiter is only one of the most recent brushes with catastrophe that spaceflight has experienced en route to Mars.

KENNEDY SPACE CENTER, FL - Following a perfectly executed three day orbital rendezvous, NASA astronaut and Expedition 47 Commander Tim Kopra successfully reached out with the International Space Station's robotic arm, Canadarm2, grabbed hold and captured Orbital ATK's commercial Cygnus cargo freighter at 6:51 a.m. EDT, this morning, Saturday, March 26, 2016.

KENNEDY SPACE CENTER, FL - This week's Atlas V rocket launch of a Cygnus cargo ship to the International Space Station (ISS) apparently experienced a first stage engine anomaly during the climb to space that required a longer firing of the boosters upper stage engine so the payload could successfully achieve the required orbit

We all know that planet Earth rotates on its axis as well as around the Sun. But this period yields some different results, depending on how you measure it.

During its recent flyby of Earth, astronomers used the Goldstone radar antenna to create a remarkable series of images of a comet never seen up close before.

KENNEDY SPACE CENTER, FL - Tuesday evening, March 22, turned into 'streaks galore' on Florida's space coast, as the nighttime launch of an Orbital ATK Cygnus cargo freighter atop an Atlas V rocket was captured in unforgettable fashion by talented space photographers as it chases down the International Space Station (ISS), loaded with hundreds of science experiments.

The final booster that sent the ExoMars spacecraft to Mars exploded not long after the two parted. Luckily, the probe appears to be safe.

The Moon had a different axis of rotation billions of years ago. The culprit? Volcanoes.

A team of astronomers have discovered 8 of the brightest galaxies ever observed. And their luminosity could tell us a lot about the early Universe.

According to a series of articles produced by NASA and industry specialists, a lunar base could be built in a few years for just $10 billion

In 2011, a coronal mass ejection reached Jupiter and produced x-ray auroras hundreds of times brighter than Earth's auroras.

Pluto's moons were likely formed as a result of a collision between Pluto and a Pluto-sized object, about 4 billion years ago.

KENNEDY SPACE CENTER, FL - A stunningly beautiful nighttime launch mesmerized delighted spectators as it roared off a Florida space coast launch pad late Tuesday night, March 22, on a mission for NASA stocked with over three tons of science and supplies bound for the multinational crews working aboard the International Space Station (ISS).

New images from NASA's Dawn spacecraft reveal spectacular new details in Ceres' intriguing "bright spots".

New Horizons data shows that Pluto may once have had a warm enough climate for liquid nitrogen to form on its surface. And it may get that warm again.
