Just a few days ago we wrote about the new FGS image of the James Webb space telescope which made us understand what the potential of this new scientific instrument will be. NASA, ESA and CSA, however, did not want us to stay too long with the “breathless” and for this reason they anticipated what the objectives of the first images and the first data of the JWST.
As we know, this space telescope it allows to capture the infrared frequencies and its potentials range in different fields allowing for example to characterize exoplanets but also to know the early Universe, a few hundred million years after the Big Bang. Furthermore JWST will collaborate to examine the center of the Milky Way and much more. And so engineers and scientists wanted to give us only a first taste of its potential in theevent to be held on July 12, 2022 from 16:30 (ESA will start live at 15:45) Italian time. And then we can see the release of data and studies for the next five years (and potentially up to 20 years thanks to the precise launch of Ariane 5).
The objectives of the first images of the James Webb Space Telescope
As written above, the agencies that collaborated in the realization of the space telescope they wanted to anticipate what the subjects we will see in the first images (and in the first data). The teams that collaborate in the management of the James Webb space telescope they wanted to choose a range of goals to leave us a “mouth open”according to the premises.
According to the official list we will see the images and data of:
- Carina Nebula – one of the largest and brightest nebulae in the sky which is 7600 light years away from Earth in the constellation of the Carina. In particular, it contains massive stars, much larger than our Sun.
- Exoplanet WASP-96 b – of this generously sized exoplanet we will see the spectrum that should resemble that of a gas giant (half the mass of Jupiter). The exoplanet is 1150 light-years from Earth and orbits its star in 3.4 days.
- NGC 3132 (Southern Ring Nebula) – it is a planetary nebula where an expanding cloud of gas surrounds a dying star. Its distance from Earth is 2000 light years.
- Stephan Quintet – is located 290 million light years from Earth and is located in the constellation of Pegasus. Its discovery dates back to 1877 and a famous image was created thanks to Hubble’s WFC3.
- SMACS 0723 – it will deal with a vision in the deep field of Space, as already anticipated in the past. This is possible thanks to a gravitational lens created by clusters of galaxies that are located at a (relative) shorter distance. This allows you to see even relatively faint objects.
After the first images and the first data, new objectives will be selected for the first year of scientific observations (also called “first cycle”). Finally, after its conception in the mid-90s and the launch that was only possible on Christmas day 2021, the James Webb space telescope is ready to show its potential. And we know it will be a da event “WOW!”.
