NASA will release the James Webb first image. This event will be held on July 12, 2022 at United states.
James Webb Telescope
The James Webb Space Telescope is a space telescope designed primarily to conduct infrared astronomy.
As the most powerful telescope ever launched into space, its greatly improved infrared resolution and sensitivity will allow it to view objects too old, distant, or faint for the Hubble Space Telescope.
It has been launched on the space on 25th December, 2021.
- To search for light from the first stars and galaxies that formed in the universe after the Big Bang
- To study galaxy formation and evolution
- To understand star formation and planet formation
- To study planetary systems and the origins of life
These goals can be accomplished more effectively by observation in near-infrared light rather than light in the visible part of the spectrum. For this reason, JWST’s instruments will not measure visible or ultraviolet light like the Hubble Telescope, but will have a much greater capacity to perform infrared astronomy. JWST will be sensitive to a range of wavelengths from 0.6 to 28 μm (corresponding respectively to orange light and deep infrared radiation at about 100 K or −173 °C).
JWST is the formal successor to the Hubble Space Telescope (HST), and since its primary emphasis is on infrared astronomy, it is also a successor to the Spitzer Space Telescope. JWST will far surpass both those telescopes, being able to see many more and much older stars and galaxies.
Observing in the infrared spectrum is a key technique for achieving this, because of cosmological redshift, and because it better penetrates obscuring dust and gas. This allows observation of dimmer, cooler objects.
Since water vapor and carbon dioxide in the Earth’s atmosphere strongly absorbs most infrared, ground-based infrared astronomy is limited to narrow wavelength ranges where the atmosphere absorbs less strongly.
Additionally, the atmosphere itself radiates in the infrared spectrum, often overwhelming light from the object being observed. This makes a space telescope preferable for infrared observation.
Revelation of James Webb First Image
The world’s premier space agency, NASA, will release the first high resolution photos of the universe captured by the James Webb Space Telescope on July 12.
NASA said, James Webb First Image will be the deepest photo of universe ever taken.
Recently, the telescope’s Fine Guidance Sensor (FGS), developed by the Canadian Space Agency, captured a stunning photo of stars and galaxies. The real work of the sensor was to find and lock on to the target. But it still captured a tantalizing photo of the universe.
Interesting facts of the image
You can expect the below from the James Webb first image.
- This photo has been taken during the stability test held on May.
- The image shows, stars far and near and several galaxies in the distance.
- The image was the result of 72 exposures
- It was taken over 32 hours
How to watch the Event?
NASA will release the photo taken by the James Webb Telescope on July 12. The live coverage of the release of the data will start from 10.30 am in the United States. It can be watched in India at 8 pm.
