In 2022, NASA has just launched James Webb Space Telescopewhich is a sophisticated telescope capable of solving various problems in astronomy.
The James Webb Space Telescope, or JWST, initially caused a lot of controversy because the name of this instrument referred to a NASA expert who had been accused of homophobic acts. Not only that, the creation of JWST itself is said to have surpassed the funds originally prepared.
Even so, in fact, the James Webb Space Telescope was able to make many people gasp, especially seeing its role in the advancement of astronomy. Here are some of the great features of JWST.
Able to show the farthest galaxy
In fact, astronomers were already able to see various types of galaxies that existed billions of years ago. Even so, JWST itself was able to break the record for seeing the most distant galaxy ever captured by human technology. This galaxy is 350 million years after the Big Bang.
This galaxy is actually quite surprising to astronomers because it looks much brighter than expected. This galaxy also does not seem to have order solar system, and therefore requires further attention from experts to study it.
Detection of planetary atmospheric content
JWST has been shown to be able to detect the atmospheric contents of planets. On the planet WASP-39b, for example, JWST saw the presence of water vapor and sulfur dioxide in its atmosphere.
Detecting the contents of this planet’s atmosphere is important if humans are to find other habitable planets. JWST is not only able to detect the composition contained in the planet’s atmosphere, but it is also able to see the interaction between the planet’s atmosphere and the light of the stars that surround it.
JWST is also used to study planets in our galaxy, such as Neptune, Jupiter and Uranus. With its advanced technology, JWST is able to capture very clear images of the auroras on the planet Jupiter and the rings of Neptune.
Used to study the life cycle of stars
With technology infrared owned by JWST, this telescope is used to examine the life cycle of stars by examining the content of dust contained by each star. This makes JWST the only instrument that has the potential to study the star formation mechanism in detail.
