A recent analysis of the fossils of ancient microorganisms from deep within Earth’s past have unveiled the presence of a surprising amount of biodiversity that flourished roughly 3.4 billion years ago, when the Earth was still a very young planet. The variety of metabolic processes that these early microorganisms used suggests that they needed time to evolve the diversity that the researchers discovered, meaning that life on Earth had to have started much, much earlier. And if life on Earth took hold that quickly in its history, what would prevent the multitude of other planets we’re discovering across the universe from forming their own lifeforms?

100 years after Albert Einstein predicted the existence of gravitational waves through his theory of general relativity, a team of astrophysicists has announced the detection of these distortions made in the fabric of space. "With this new discovery, we humans are embarking on a marvelous new quest: the quest to explore the warped side of the Universe—objects and phenomena that are made from warped spacetime," remarks gravitational physicist Kip Thorne.
