Cosmic Tarantula: James Webb captures thousands of never-before-seen stars in celestial ‘nursery’ | Sciences

161,000 light-years away from Earth is the Tarantula Nebula. Star forming region filled with gas and dust And the “neighbor” of our Milky Way galaxy.

Habibi is considered to be the astronomers who study these “stellar nurseries”, and it was this cosmic structure chosen for the most recent James Webb Super TelescopeThe largest and most powerful space telescope ever built.

Pictures (see above and onwards below), A mosaic of super-detailed images, not only revealing the characteristics of this dusty region laden with hot and strong winds, but also showing some galaxies in the background and Tens of thousands of young stars never seen before (The tarantula dust “hidden” these structures from other telescopes.)

Both photos were released by NASA And from the European Space Agency and the American and European space agencies, Thursday morning (1).

NASA explains that the nebula got its strange nickname because of its threads that stretch across the image like spider legs.

The cosmic structure is the largest and brightest star-forming region of the Local Group, the closest galaxies to our Milky Way.

According to the space agency, this cosmic nursery is home to the most famous and massive stars known to science.

“One of the reasons why the Tarantula Nebula is so interesting to astronomers is that it has a kind of chemical composition similar to the giant star-forming regions seen at the ‘cosmic noon’ in the universe, when the universe had only a few stars, billions of years ago and star formation was At its peak, NASA explains.

According to the European Space Agency, these “stellar nurseries” in our Milky Way galaxy do not produce stars with the same frantic speed as the Tarantula Nebula and have a different chemical composition. And therefore, This space tarantula is the closest example (ie easier to see in detail) What would happen when our universe approached the bright “cosmic noon”.

“Despite thousands of years of stargazing, the process of star formation still holds many mysteries – many of which are due to our previous inability to obtain clear images of what was happening behind the thick clouds of stellar nurseries,” he said. European Agency.

Scientists have some ambitious goals for James Webb. According to NASA, the $10 billion super telescope will help solve puzzles in our solar system, look at very distant worlds, investigate the origins of our universe, and can also explore the possibility of life in distant planetary systems.

“[O James Webb] It had already begun to reveal an unprecedented world and had just begun to rewrite the history of astral creation. ”
