The search for life beyond our solar system requires unprecedented cooperation across scientific disciplines. NASA's NExSS collaboration includes those who study Earth as a life-bearing planet (lower right), those researching the diversity of solar system planets (left), and those on the new frontier, discovering worlds orbiting other stars in the galaxy (upper right) (Image NASA)

NASA has announced the creation of the NExSS (Nexus for Exoplanet System Science), coalition, an initiative dedicated to the search for life on planets outside the solar system. It puts together different disciplines because this research goes beyond just astronomy: for example, it’s of interest to planetary and climate science researchers.

When astronomers started studying a map of the cosmic microwave background radiation (CMB or CMBR), the residue of the earliest stages of the universe, they found what was called the Cold Spot. That’s a huge area colder than expected which could be the largest single cosmic structure never identified. According to an international team of scientists consists of a cosmic supervoid which about 1.8 billion light years across.

In late 2010, NASA’s space probe Cassini started observing a huge storm on Saturn lasting for several months. In recent days, an article was published on the journal “Nature Geoscience” that provides an explanation for this phenomenon that had been observed a number of times in the last 140 years but had remained mysterious. According to a team led by Cheng Li of CalTech, Pasadena, the presence of water is the key to its origin.

A few hours ago the SpaceX Dragon spacecraft blasted off on a Falcon 9 rocket from Cape Canaveral in its CRS-6 (Cargo Resupply Service 6) mission, also referred to as SPX-6. This is the 6th of 12 missions that for the Dragon spacecraft to the International Space Station with a cargo and its return to Earth, again with a cargo.
