Detection of phosphine in Venus’ clouds is a big deal as it may be a sign of life
On Sept. 14, 2020, a new planet was added to the list of potentially habitable worlds in the Solar System: Venus. Phosphine, a toxic gas made up of one phosphorus and three hydrogen atoms (PH₃), commonly produced by organic life forms but otherwise difficult to make on rocky planets, was discovered in the middle layer …
Twin spacecraft to study “rubble pile” binary asteroids
The official go-ahead has been given by NASA to a mission to launch a pair of small spacecraft to capture the first-ever closeup look at a mysterious class of solar system objects: binary asteroids. These bodies are pairs of asteroids that orbit around each other in space, much like the Earth and Moon. In a project …
