James Webb Space Telescope in a nutshell.
JWST will observe the Universe in the near-infrared and mid-infrared – at wavelengths longer than visible light. To do so, it carries a suite of state-of-the-art cameras, spectrographs and coronagraphs.

Journey to L2.
JWST will orbit the second Lagrange point (L2), 1.5 million kilometers from Earth in the direction away from the Sun. It's sunshield can always block light and heat from both the Sun and Earth from reaching its telescope and instruments.

JWST unfolding sequence.
During the first month in space, on its way to the second Lagrange point (L2), Webb will undergo a complex unfolding sequence.

Comparing JWST and Hubble.
Webb often gets called the replacement for Hubble, but we prefer to call it a successor. Hubble's science pushed us to look to longer wavelengths to "go beyond" what Hubble has already done. #UnfoldTheUniverse

Spectroscopy is a tool to better understand the physics of objects in space. Like a prism splits white light from the Sun into its color components (like a rainbow), the JWST spectrographs will split infrared light into its many wavelengths.

Exoplanet mission timeline
The first discoveries of exoplanets in the 1990s, by ground-based observatories, completely changed our perspective of the Solar System and opened up new areas of research that continues today. #UnfoldTheUniverse
