The James Webb Space Telescope is a state-of-the-art space telescope designed to observe the most distant objects in the Universe, as well as provide images and spectra of objects in our own solar system. It is a joint project of NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The telescope is named after James E. Webb, who served as the second administrator of NASA from 1961 to 1968 and played a key role in the Apollo program.

Back in July, the JWST revealed the first full-color images of the Universe during an event that was awaited by the entire community of astronomers. One of the images shows the Carina Nebula in all its glory, meaning a beautiful cosmic structure that’s placed 7,500 light-years away from Earth. 

We now have the possibility to admire the so-called “cosmic cliffs” of the nebula in 4K footage, meaning “a region at the edge of a gigantic, gaseous cavity within the star cluster NGC 3324,” as NASA/ESA reveals. The Carina Nebula is also huge, as you’ve probably already guessed. It has a radius that reaches 230 light-years. 

The nebula is also one of the largest and most active star-forming regions in our Milky Way galaxy, with a size that is roughly four times that of the Orion Nebula.

The Carina Nebula harbors some of the brightest stars in the Milky Way

The Carina Nebula is home to some of the most massive and luminous stars in the galaxy, including Eta Carinae, which is one of the most luminous stars known and has a mass that is estimated to be around 100 times that of the Sun. The intense radiation and strong winds from these massive stars have shaped the nebula’s appearance, carving out huge cavities and sculpting intricate patterns of gas and dust.

The Carina Nebula is also a source of many interesting objects, including planetary nebulae, supernova remnants, and young stellar clusters. The most famous of these is the Trapezium Cluster, a group of several hundred young stars that are just a few million years old and are surrounded by a bright, glowing cloud of gas.The Trapezium Cluster also has a radius that measures 10 light-years.

The Carina Nebula has been studied for centuries, and it continues to be a subject of fascination for astronomers and space enthusiasts. It has been observed by many telescopes, including the Hubble Space Telescope, which has provided some of the most detailed images of the nebula. Surely many other telescopes will follow suit, except for Hubble and Webb since they have already observed the nebula.

Our Milky Way is an active galaxy with a supermassive black hole at its center. This black hole, called Sagittarius A*, is about 4 million times the mass of the Sun and is the source of powerful gravitational forces that shape the galaxy. The Milky Way is also home to many other objects of interest, including nebulae, supernova remnants, and globular clusters.

The Milky Way is constantly evolving, with new stars being born and old stars dying. This process is driven by the galaxy’s supply of gas and dust, which are used to form new stars and planetary systems. The Milky Way is also influenced by its interactions with other galaxies, which can affect its shape and structure.

The JWST is designed to operate in the infrared range of the electromagnetic spectrum, which allows it to detect objects that are too cold or too distant to be seen by telescopes that only operate in visible light. This makes the JWST particularly well-suited for studying the early Universe and for searching for the first galaxies that formed after the Big Bang.
