James Webb Space Telescope

Exoplanets, worlds beyond our own Solar System, are a wild bunch: some are gas giants like Jupiter, but are scorching hot due to orbiting closer to their star than Mercury does the Sun, some are frozen hulks, while others may be water worlds covered entirely by ocean, and still others may sport clouds and rain of liquid gemstones.

And some of them, somewhere, could host life as we know. Or even as we don’t.

Scientists have discovered thousands of these worlds since the 1990s, and exoplanet science has already changed the yway scientists think about the universe, and our place within it.

But with the launch of the James Webb Space Telescope in December 2021, exoplanetary science stepped into a new era.

The Webb telescope sports new, sensitive instruments designed to work with the observatories uniquely powerful optics to peer deeply at exoplanets and decipher their secrets, characterizing the chemicals in their atmosphere to help chart their history and evolution, understand their present climates, and just maybe catch signs of biological activity.
