The origin of the term plankton is from the Greek word πλαγκτός meaning "I drift (myself)".... click to read more

Space-based observatories such as the Hubble Space Telescope are providing valuable insights into the atmospheres of planets outside our solar system, known as "exoplanets". We have recently used Hubble to uncover the most compelling evidence to date for a stratosphere layer on one such exoplanet,... click to read more
