Observations made with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed evidence for a moon-like object in the CD-35 2722 system. Unlike moons in our solar system, the newly found object does not orbit a planet, raising questions about what to name it. Instead, it circles a brown dwarf, an object larger than a planet, that orbits the CD-35 2722 star.

Billion plastic pellets spilled into UK river after two ships collide

Up to 25 tonnes of nurdles, the raw material for plastic manufacturing, have spread further than initially fearedApproximately a billion tiny plastic nurdles have entered the River Tyne after a “devastating spill”, with the pellets thought to have spread much further than first thought. Nurdles are tiny pellets, usually about 1-5mm in size, that act as the raw material to manufacture most plastic products.
