NASA’s James Webb Space Telescope: what nebulae have been imaged? These are all the details
Academics, science enthusiasts and the general public have marveled at the first images of the Universe captured by the James Webb Space Telescope and released by NASA. It is just the beginning of a new look at space.
But what is what in each image? What are the space landscapes photographed by the telescope?
We will analyze each image broadcast by the US space agency to get to know our neighbors better.
Webb’s first deep field
It is the image that will go down in history as the first released from the James Webb Space Telescope. What are observed? Stars, but with the deepest infrared view of the Universe to date. They are a cluster of galaxies, made up of stars, gas clouds, planets, cosmic dust, dark matter. “We can’t take the sky blank,” explained Jane Rigby, an astrophysicist at NASA’s Goddard Space Flight Center. “Wherever we look, there are galaxies.”
Nebulae are regions of the interstellar medium made up of gases, such as hydrogen and helium, and chemical elements in the form of cosmic dust. Carina’s is one of the largest and brightest in the sky, located 7,600 light-years away in the southern constellation of Carina.
What do we see in the image? The stars that make up the Carina Nebula, on the so-called Cosmic Cliffs, which are gases with that terrestrial form.
South Ring Nebula
NASA released two images of the South Ring Nebula. It is also called an “eight burst” nebula, an expanding cloud of gas surrounding a dying star. According to the aerospace agency, it is almost half a light-year in diameter and approximately 2,000 light-years from Earth.
Discovered by the Frenchman Edouard Stephan in 1877, it is a group of five galaxies in the Pegasus constellation. It is 290 million light years away. Four of the five galaxies within the quintet are seen in the image, “caught in a cosmic dance of repeated close encounters.”
