Cosmic Sights Galore: NASA Reveals First James Webb Space Telescope Images

NASA has finally revealed the first batch of observations taken by the James Webb Telescope, which includes an infrared analysis of a planet outside our solar system.

The first observation focused on a planet calledWASP-96b, a gas giant that resides about 1,150 light years away. James Webb Telescope has taken a “spectrum(Opens in a new window)” of WASP-96b, which involves analyzing the light emitted from the planet as it crosses over its parent star.

The spectrum indicates the presence of water and the evidence of clouds over the planet, which the telescope confirmed for the first time,according(Opens in a new window)to NASA.

The second observation focuses on theSouthern Ring Nebula, which is about 2,500 light years away. The nebula is made up of a dying star that has ejected its outer layer, forming a shell of gas. Ground-based telescopes have taken images of the nebula before, but the James Webb Telescope is now giving astronomers a far more detailed view of the cosmic cloud.

The image on the left is a near-infrared image, which shows the colorful structure to the nebula’s gas shell. The right-hand image was taken in mid-infrared. The imaging reveals the presence of a second star in the nebula’s center, which is surrounded in dust, making it hard for other telescopes to see.

The third observation coversStephan’s Quintet, a grouping of five galaxies, which mainly resides about 300 million light years away. The image itself “contains over 150 million pixels and is constructed from almost 1,000 separate image files,” NASAsays(Opens in a new window).

The space agency adds: “Webb shows never-before-seen details in this galaxy group. Sparkling clusters of millions of young stars and starburst regions of fresh star birth grace the image. Sweeping tails of gas, dust and stars are being pulled from several of the galaxies due to gravitational interactions.”

The telescope also took a mid-infrared of the galaxy cluster, which shows the presence of an active blackhole in the top galaxy, dubbed NGC 7319. According to NASA, the blackhole has about 24 million times the mass of the Sun. "It is actively pulling in material and puts out light energy equivalent to 40 billion Suns," the agency says.

The James Webb Telescope also focused on theCarina Nebula, a huge cloud of gas that acts as a stellar nursery, giving birth to new stars. The telescope’s infrared cameras were able to image hundreds of previously unseen young stars within the nebula, which is about 8,500 light years away.

The cliff-like structure of the nebula is actually made up of gas. According to the NASA, the tallest peaks about seven light-years high. "The 'steam'” that appears to rise from the celestial 'mountains' is actually hot, ionized gas and hot dust streaming away from the nebula due to the relentless radiation," NASA says.

The final image was revealed yesterday during a White House event. NASA provided more details about the image, which focuses on a region of space calledSMACS 0723.

The picture shows thousands of galaxies at different distances. The white-colored galaxies reside over 4 billion light years away, about the time our Sun formed. Meanwhile, the stretched red-colored galaxies are over 13 billion light years away, representing some of the earliest galaxies to ever form in our universe.

周二的揭示是一个纯粹的味道的詹姆斯Webb Space Telescope is capable of. Following half a year of testing, the space-based telescope is now ready to conduct scientific observations of other cosmic sights, including other planets outside our solar system. So you can expect to see many more stunning images from the telescope in the coming weeks and months.
