This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.

Called the Cosmic Cliffs, Webb’s seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peaks” in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.

Why the New James Webb Space Telescope Images are Such a Big Deal
by Brian Resnick
July 12, 2022

Introduction:
(Vox) Last year, before the launch of the James Webb Space Telescope, I wrote: “the largest space telescope in history is about to blow our minds.”

Consider this mind blown. NASA has finally revealed its first images from the space-based observatory. These images are decades in the making, and come after years of delays and budgets being blown. But they do not disappoint. Consider this very first image released by the space agency on Monday:

(See image posted by W.J. Fox on July 12, 2022. The post immediately preceding the image titled Hot Gas Exoplanet Wasp-96 – Atmosphere Composition)

What makes this image so mind-blowing is how small it is, and how large it is, at the same time.

It’s small in the sense that this image represents only a teensy tiny portion of the night sky. Imagine you are holding out a grain of sand at arm’s length. The area of sky that grain covers — that’s the size of the area captured in the above image.

But it’s huge in the sense that nearly every object in this image is a galaxy (besides the bright spiky starbursts, which are stars in the foreground). Think about that: In every pinprick of sky, there are thousands and thousands of galaxies, at least.
