In the almost 30 years since the Hubble Space Telescope was launched it has transformed our view of the Universe. Hubble has played a key role in many of the most important discoveries of the past few decades, including: providing dramatically improved constraints on the age of the Universe, the discovery of the accelerated expansion of the Universe, the presence of water and other molecules in the atmospheres of planets around other stars, and the discovery the most galaxies harbour a super-massive black hole at their heart.
Hubble will soon be succeeded by the Webb Telescope, due for launch in 2021. Webb’s larger mirror, more sensitive cameras, and position away from the Earth will provide dramatic improvements in sensitivity and resolution allowing it answer many of our outstanding questions. Webb is currently under construction by NASA, the European Space Agency, and the Canadian Space Agency.
