What do images from the James Webb Space Telescope tell us?  (The secrets of the universe are slowly being revealed…)

NASA, after many years of waiting James Webb Space Telescope launched into space last year. The first images from the telescope, which recently began its mission to show us the unexplored sides of space had come† The first color photo taken by the space telescope was shared by NASA at an event attended by US President Joe Biden.

After this Tuesday event and the images eagerly awaited by the whole world, super powerful optical instrument More images are sure to come from the James Webb Space Telescope (JWST), dubbed The First Five Images are considered a huge success and the culmination of a 26-year process to enable humanity to see into space in even greater detail. Let’s take a look at what these five images want to tell us about the universe.

Signs of water and clouds appear on exoplanet

JWST image

Alone in the Milky Way more than 5,000 approved exoplanet or planets orbiting a star other than the sun. The Existence of So Many Exoplanets “Aren’t We Alone in the Universe?” begs the question. The exoplanet in the image shared by JWST WASP-96bIt is located 1150 light-years away. This exoplanet is of twice Jupiter Lake smallbut a gas giant 1.2 times larger in diameter, in terms of NASA “fluffy planet” is accepted as

The fuzzy planet, which has a short orbit around its star and is not polluted by light from nearby objects, has become a prime target for JWST’s optical power. However, this image is a snapshot of the transmission diversity, not the atmosphere of an exoplanet. According to the images shared by JWST, it is located on an exoplanet. water signs even of the clouds There are traces of its existence.

Stars leave shells of gas and dust as they age

JWST, Southern Ring Nebula

JWST also official NGC 3132 or “Southern Ring NebulaHe also studied a planetary nebula called ” 2500 light years away This nebula has also been previously imaged by the Hubble Space Telescope, but NASA has announced that this updated image from JWST provides more detail about the elegant structures surrounding the binary star system.

Of the two stars in the image, a fainter, dying star and a younger, brighter star are in the lower left. The images also show NASA’s “shells” around the stars It also marks a period when what he calls a dim, dying star (the white dwarf in the image lower left) loses some of its mass. That is, as the stars get older and lose their power, they enter the universe. gas and powder shells it lets go.

The cosmic dance of Stephan’s Quintet is more clearly revealed

Stephan's Quintet

It was first observed by the French astronomer Édouard Stephan in 1877. Stephen’s Quintetshows the strange interplay of five galaxies in more detail than ever before. This latest image shared by JWST was the clearest and largest image yet.

In this slightly misleading image, the far left galaxy is actually in the foreground and is about 40 million light years away is located. So far, the four galaxies are roughly: 290 million light years away† These four galaxies are clustered so closely together that they actually interact with each other. One of the most striking aspects of the image is that even a supermassive black hole, about 24 million times the mass of the Sun, located at the center of the upper galaxy, was clearly visualized.

JWST also provided a better study of the Carina Nebula

Carina Nebula

an area of ​​the Milky Way about 7,600 light-years away Carina Nebula, displayed more clearly thanks to JWST. Hundreds of new stars have been observed in the nebula. Thanks to JWST, it became clear that star formation is not a serene event, but one characterized by highly unstable processes that can be both productive and destructive in some ways.

The smooth amber landscape at the bottom of the image shows a large, chaotic star-forming region of the nebula. This region is so big that NASA “Cosmic Abyss” and the highest points in this amber band are about seven light-years high.

The data from the JWST is expected to give scientists more insight into the star formation process and help determine why certain numbers of stars form in certain regions and how this results in the mass that the stars have.
