A mysterious radio explosion with a pattern similar to a heartbeat has been detected in space. Astronomers estimate that the signal came from a galaxy about a billion light years away, but the exact location and cause of the explosion is unknown. A study detailing the findings published Wednesday in the journal Natural . Rapid radio bursts, or FRBs, are intense, millisecond-long bursts of radio waves of unknown origin. The first FRBs were discovered in 2007, and since then, hundreds of these rapid cosmic flashes have been detected coming from various distant points throughout the universe.

Fast radio bursts are so fast and unpredictable that they are difficult to observe. One of the sources used to find them is a radio telescope called th

The heart of the Milky Way appears to be a hotspot for molecules that combine to form RNA. A new survey of the thick molecular cloud that shrouds the galactic center has revealed the presence of various nitriles – organic molecules that are often toxic in isolation, but are also molecular building blocks essential for life. The increase in prebiotic molecules (molecules involved in the emergence of life) identified at the center of galaxies, particularly those associated with RNA, has implications for our understanding of how life emerged in the Universe – and how it happened on Earth. “Here we show that the chemistry occurring in the interstellar medium is able to efficiently form some of the nitriles, which are key molecular precursors of the ‘RNA World’ scenario,” explains astrobiologist Víctor Rivilla of the Spanish National Research Council and National Institutes. Aerospace Technology in Spain. Exactly how life arose on Earth is a mystery that basic scientists are eager to achie
