Phosphine and Glycine, two Biomolecules, were Discovered in Venus's Atmosphere; here is what that means:

For centuries, humans looked up at the brightest planet in our night sky and thought, “could someone be looking back at us?” Venus was always considered to be Earth’s twin sister; the two planets hold alike similar orbits, they are both within the general habitable zone of the Sun, they are both similar in size, mass, and of course gravity; wouldn’t it make sense that under those vibrant orange clouds, there would be another species of extraterrestrials. This is how we thought all the way until the 1960s, when the great planetary astronomer Carl Sagan discovered an immense greenhouse effect occurring on Venus. For the moment, our dreams of a great planetary partner world brimming with extraterrestrial life were diminished; still, there is a great phrase that goes as such: “there is always a way around everything.” It is possible that we may or may not have found how a hypothesized extraterrestrial found a way around Venus’s hellish conditions.
