Biggest Leap of Human Beings - James Webb Telescope

What is James Webb Telescope?

• The James Webb Space Telescope (JWST) is a large, space-based observatory that is set to launch in 2021. It is being developed and built by NASA, with significant contributions from the European Space Agency and the Canadian Space Agency. The JWST will be able to observe in the infrared part of the electromagnetic spectrum, allowing it to see through dust clouds and into the early universe. It is considered as the successor of the Hubble Space Telescope. It will be able to study the first galaxies that formed in the early universe, as well as the formation of stars and planets. It will also be able to study the atmospheres of exoplanets, which are planets that orbit stars other than the Sun.

1. First Picture of James Webb (Carina Nebula):

• The landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.

• The Cosmic Cliffs, Webb’s seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peaks” in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.

SOUTHERN RING NEBULA

• The Southern Ring Nebula (also known as PN G315.4-02.3) is a planetary nebula located in the constellation of Norma, it is not well known and it was discovered in the 1990s. Planetary nebulae are the final stage in the life of a low-mass star like the Sun. As these stars exhaust the nuclear fuel in their cores, they begin to puff off their outer layers of gas. This gas is then ionized by the intense ultraviolet radiation from the hot, dying star at the center of the nebula, causing it to glow and create the colorful, complex structures that we see in images of planetary nebulae. The Southern Ring Nebula is relatively small and faint compared to other planetary nebulae, and it is not well studied.

• It is not a well-known object and not many images of it have been released, but it is thought to have a ring shape and a bright central star.

the JWST will be able to observe the Southern Ring Nebula in the infrared part of the electromagnetic spectrum, which would allow it to see through the dust clouds and get a more detailed view of the nebula.

• The JWST has several scientific instruments on board, including the Near Infrared Camera (NIRCam), the Near Infrared Spectrograph (NIRSpec), and the Mid-Infrared Instrument (MIRI). These instruments will be able to take high-resolution images and spectra of the Southern Ring Nebula, providing new insights into its structure and the processes that are shaping it.

• It's worth noting that Southern Ring Nebula is a relatively faint object, and it is not well studied, JWST is a powerful telescope and it will be able to observe many new and faint objects. It will help us to understand the universe more but it's not guaranteed that it will be able to observe the Southern Ring Nebula.

• Here there are lots of Photographs are released by the James Webb Telescope. Those Picture and details will be release upcoming articles.
