peacock, peacock! Scientists discover record-breaking “megamaser” 5 billion light-years away.

In just one night of observing, scientists discovered a new record breaker – the most distant megamaser known to date.

A megamaser is a super-powerful laser of microwave light (hence maser). Megamaser comes in different flavors, but the one discovered by the scientists is the most common type, which shows the signal from hydroxyl, a molecule made up of an oxygen atom and a hydrogen atom. The team argues that the newly discovered megamaser, one of the brightest beams of its kind known so far, marks one galactic collision.
