... were around in the Universe at that time; hydrogen and helium. Heavier elements such as carbon, oxygen and nitrogen only appeared after being created by fusion processes deep within the first stars. These atoms then...
... of plastics and nitrites and in conflict as a chemical warfare agent. Hydrogen cyanide on Earth was thought to be produced when nitrogen in the atmosphere interacted with carbon that slammed into the young Earth in the form of meteorites. Powered...
... fundamental ingredients of life as we know it are amino acids; a simple organic compound containing carbon, hydrogen, oxygen, and nitrogen, that build on one another to form proteins. To start the building process though, amino acids also need...
... which are then lost to space, allowing for longer-chain chemical reactions to take place involving carbon or nitrogen. Tentative fingerprints of methane, along with water ice have potentially been observed on Ultima by LEISA, say Stern...
... say Kamata and colleagues. What’s more the gas in the hydrates is most likely methane, and not nitrogen, which is what Sputnik Planitia is thought to be composed of. These molecules once released, then escape to help fill up Pluto...
... certain, but perhaps somewhere you wouldn’t want to go for a swim. Also like Earth, Titan is encased by a thick nitrogen atmosphere, but unlike our temperate planet, given the enormous distance separating it from the Sun – some...
