Earliest Known Life Form

The Earth sits inside a 300 pc-wide void that was carved by a series of supernova explosions that went off tens of millions of years ago, pushing away interstellar gas and creating a bubble-like structure. The 60 Fe peak deposits found in the deep-sea crust have been interpreted by the imprints left by the ejecta of supernova explosions occurring about 2–3 and 5–6 Myr ago. It is likely that the 60 Fe peak at about…

One of the biggest scientific mysteries is where life on Earth started. Research has often focused on the role of deep-sea hydrothermal vents – those towering structures on the ocean floor constantly pumping out a melange of organic and inorganic material. Within these plumes are minerals called iro...
