We all have wondered how tiny we are in the grand scheme of the cosmos. And now we can look in awe at the images produced by NASA’s newest and most advanced telescope!
NASA’s James Webb Telescope has revealed the sharpest and deepest images of our universe – so far. The telescope’s First Deep Field is a cluster of galaxies SMAC 0723 and it is grouped with thousands of galaxies, including the faintest observable objects so far. This is yet another achievement of humankind in our pursuit to know the hidden secrets of the universe, and our quest is never ending so it seems.
Webb’s first image is approximately the size of a grain of sand that’s held at an arm’s length and it just shows how vast and infinite our universe really is. The mass of this cluster is a gravitational lens that magnifies the galaxies that are distant, and what we see is a cluster that is about a billion years old – an early glimpse of the universe.
Astrophysicists theorize that the most distant stars in the galaxies are unlike what we see today – the earliest stars being composed of pure hydrogen and helium after the big bang. The newest images reveal how the stars are far more massive than the sun and then collapse suddenly into blackholes; that are now part of our infinitely growing universe.
After the big bang, these images are perhaps the closest detail we can get to how the universe was created and how it has evolved ever since. Light rays from these galaxies took billions of years to reach us and the gravitational field has caused them to bend such as in the images. Scientists, physicists and researchers will begin learning and exploring more about the origins of our universe.
Megan Mansfield, an astronomer at the University of Arizona theorizes that scientists have an even better chance of finding out about other forms of life and other planets that can have signs of life as well. James Webb is definitely a milestone that’s been achieved in the field of science and technology. One of the most striking images taken is the image of the Carina nebula, which is a vast swirling cloud of dust that resides with other explosive stars in the Milky Way. As always, there is room for the unexpected to happen and scientific exploration will never cease to amaze us!
