A brief introduction to James Webb space telescope |
NASA's James Webb Space Telescope is an infrared space observatory that was launched on Dec 25, 2021, from ESA's launch site at Kourou in French Guiana on board an Arianespace Ariane 5 rocket.
James Webb Space Telescope will probe the cosmos to uncover the history of the universe from the Big Bang to alien planet formation and beyond. It is one of NASA's Great Observatories, huge space instruments that include the likes of the Hubble Space Telescope to peer deep into the cosmos.
According to NASA, the James Webb Space Telescope will focus on four main areas: first light in the universe, assembly of galaxies in the early universe, birth of stars and protoplanetary systems, and planets.
Once the JWST has launched, it will undergo a series of science and calibration tests including sunshield deployment, telescope deployment, instrument turn-on and telescope alignment.
According to the Space Telescope Science Institute, the best images from JWST will start to appear about six months after launch. Though we may possibly be treated to some "first light" images slightly earlier.
The powerful James Webb Space Telescope is also expected to take amazing photos of celestial objects like its predecessor, the Hubble Space Telescope.
Luckily for astronomers, the Hubble Space Telescope remains in good health and it's probable that the two telescopes will work together for JWST's first years.
JWST will also look at exoplanets that the Kepler Space Telescope found, or follow up on real-time observations from ground space telescopes.
