NASA and other agencies are building a handful of telescopes to probe the universe's most puzzling mysteries.
From vantage points on Earth and in space, the upcoming telescopes will rely on next-generation technologies in their attempts to answer some of scientists' biggest questions about dark matter, the expansion of the universe, and alien life.
Some will provide 100 times more information than today's most powerful tools for observing the skies.
The first of these telescopes, NASA's highly anticipated James Webb Space Telescope, is slated to launch in 2021, then start scanning the atmospheres of distant worlds for clues about extraterrestrial life. As early as 2022, other new telescopes in space will take unprecedented observations of the skies, while observatories on Earth peer back into the ancient universe.
Here's what's in the pipeline and what these new tools could reveal.
