Quote:During a spacewalk intended to clean the International Space Station, Russian astronauts took samples from the exterior of the station for a routine analysis. The results of the experiment were quite surprising. Astronauts expected to find nothing more than contaminants created by the engines of incoming and outgoing spacecraft, but instead found that living organisms were clinging to outside of the ISS. The astronauts identified the organisms as sea plankton that likely originated from Earth, but the team couldn’t find a concrete explanation as to how these organisms made it all the way up to the space station — or how they managed to survive.

Quote:The surface of Europa is frozen, covered with a layer of ice, but scientists think there is an ocean beneath the surface. The icy surface also makes the moon one of the most reflective in the solar system. Water plumes were spotted jetting from the moon in 2013, although those observations have not 

Quote:Marine researchers have discovered a strange alien-like creaturewhile exploring the underwater world found in the deepest ocean trench on Earth.
A team of scientists from the National Oceanic and Atmospheric Administration (NOAA) spotted the hydromedusa jellyfish during an expedition to the Mariana Trench in the Pacific. The sea creature was captured on film after it swam close to the surface of the ocean near the agency's research ship, the "Okeanos Explorer."
Based on the team's observations, this new jellyfish species shares similar features with those of Crossota genus, which are known to spend the majority of their existence gliding through the water.

Quote:A fish that has never been seen alive before has been caught on camera swimming in the depths of the western Pacific Ocean’s Mariana Trench.
“I am sure that this is an Aphyonid and I am sure that this is the first time a fish of this family has ever been seen alive,” he added. “This is really an unusual sighting.”

Quote:A new experiment simulating conditions in deep space reveals that the complex building blocks of life could have been created on icy interplanetary dust and then carried to Earth, jump-starting life.
Chemists from the University of California, Berkeley, and the University of Hawaii, Manoa, showed that conditions in space are capable of creating complex dipeptides – linked pairs of amino acids – that are essential building blocks shared by all living things. The discovery opens the door to the possibility that these molecules were brought to Earth aboard a comet or possibly meteorites, catalyzing the formation of proteins (polypeptides), enzymes and even more complex molecules, such as sugars, that are necessary for life.
“It is fascinating to consider that the most basic biochemical building blocks that led to life on Earth may well have had an extraterrestrial origin,” said UC Berkeley chemist Richard Mathies, coauthor of a paper published online last week and scheduled for the March 10 print issue of The Astrophysical Journal.
While scientists have discovered basic organic molecules, such as amino acids, in numerous meteorites that have fallen to Earth, they have been unable to find the more complex molecular structures that are prerequisites for our planet’s biology. As a result, scientists have always assumed that the really complicated chemistry of life must have originated in Earth’s early oceans.
