Looking Ahead to Webb’s First Images
1 June 2022
The NASA/ESA/CSA James Webb Space Telescope will release its first full-colour images and spectroscopic data on 12 July 2022. As the largest and most complex observatory ever launched into space, Webb has been going through a six-month period of preparation before it can begin science work, calibrating its instruments to its space environment and aligning its mirrors. This careful process, not to mention years of new technology development and mission planning, has built up to the first images and data: a demonstration of Webb at its full power, ready to begin its science mission and unfold the infrared universe.
Behind the Scenes: Creating Webb’s First Images
Deciding what Webb should look at first has been a project more than five years in the making, undertaken by an international partnership between NASA, ESA, the Canadian Space Agency, and the Space Telescope Science Institute (STScI) in Baltimore, home to Webb’s science and mission operations.
Once each of Webb’s instruments has been calibrated, tested, and given the green light by its science and engineering teams, the first images and spectroscopic observations will be made. The team will proceed through a list of targets that have been preselected and prioritised by an international committee to exercise Webb’s powerful capabilities. Then the production team will receive the data from Webb’s instrument scientists and process it into images for astronomers and the public.
What Will We See?
While careful planning for Webb’s first full-colour images has been underway for a long time, the new telescope is so powerful that it is difficult to predict exactly how the first images will look.
Early alignment imagery has already demonstrated the unprecedented sharpness of Webb’s infrared view. However, these new images will be the first in full colour and the first to showcase Webb’s full science capabilities. In addition to imagery, Webb will be capturing spectroscopic data – detailed information astronomers can read in light. The first images package of materials will highlight the science themes that inspired the mission and will be the focus of its work: the early universe, the evolution of galaxies through time, the lifecycle of stars, and other worlds. All of Webb’s commissioning data – the data taken while aligning the telescope and preparing the instruments – will also be made publicly available.
Science! After capturing its first images, Webb’s scientific observations will begin, continuing to explore the mission’s key science themes. Teams have already applied through a competitive process for time to use the telescope, in what astronomers call its first “cycle,” or first year of observations. Observations are carefully scheduled to make the most efficient use of the telescope’s time.
These observations mark the official beginning of Webb’s general science operations – the work it was designed to do. Astronomers will use Webb to observe the infrared universe, analyse the data collected, and publish scientific papers on their discoveries.
Beyond what is already planned for Webb, there are the unexpected discoveries astronomers can’t anticipate. One example: In 1990 when the NASA/ESA Hubble Space Telescope launched, dark energy was completely unknown. Now it is one of the most exciting areas of astrophysics. What will Webb discover?
Join The Celebration
This top-secret and highly anticipated collection of images and spectra are intended to be shared widely around the world. To help celebrate this important release, ESA/Webb is inviting proposals from organisations, institutions, and groups across Europe to maximise the reach and impact of these products with special events. These products will be provided in digital format and we welcome creative and innovative ideas for how these images and spectra can be shared with the greater public across Europe.
Please see the official solicitation call for more information on how to get involved. The deadline for applications is 8 June 2022.
