Webb reveals cosmic cliffs and it's beautiful!



So NASA’s James Webb telescope released an image of cosmic cliff and we all are amazed. It shows the limitlessness of Webb suggesting that Webb cameras are capable enough to peer through cosmic dust which could essentially reveal how stars form.


So the extremely beautiful image you see above is actually much more than just a beautiful background for your computer. Those mountains and valley structure you see decorated with stars lingering around it is actually an edge of a star-forming region called NGC 3324 in Carina Nebula. To give a sense of the dimensions: the tallest “peak” is as high as 7 light-years


The NGC 3324 observation will reveal to us the process of star formation. We do know a lot about how a star takes birth but for those who are not aware, below is a summary. Stars are formed in clouds of gas and dust and turbulence from deep within the clouds causing knots which starts to collapse due to gravitational attraction. This makes the core of the star heat, eventually leading to fusion and a star forms.


Objects in the earlier stages of star formation are much harder to capture but the genius engineering of Webb can record these elusive events. Webb reveals spellbound nurseries and individual stars that are absolutely hidden in visible-light pictures. Scientists have had little data about the multitude of young stars but with Webb, this gap could be filled


Webb will also uncover the effect of star formation on the evolution of gigantic clouds of gas and dust. While the effect of massive stars is known, less is known about the influence of the low-mass stars. As they form, these smaller stars create narrow, opposing jets seen here, which can inject a lot of momentum and energy into the clouds.

About the James Webb Space Telescope by Nasa:


The James Webb Space Telescope is the world's premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
