The New Composite James Webb Image Is So Beautiful Ive Been Staring At It For 10 Minutes Straight

Over 800 terrestrial exoplanets visualized and arranged according to their equilibrium temperature and size.

Going for a walk. Apollo 17 astronaut Ronald Evans leaves to the spacecraft to retrieve film cassettes from the Service Module, Dec 1972. Mr. Evans was Command Module Pilot & orbited the moon a record 75 times during the mission. He holds the record for most time spent in lunar orbit at just shy of 148 hours. He is the last human to orbit the moon solo. A historic figure in space pioneering.

The Cat’s Eye Nebula in Optical and X-ray Image Credit: NASA, ESA, Hubble Legacy Archive; Chandra X-ray Obs.; Processing & Copyright: Rudy Pohl

Explanation: To some it looks like a cat’s eye. To others, perhaps like a giant cosmic conch shell. It is actually one of the brightest and most highly detailed planetary nebula known, composed of gas expelled in the brief yet glorious phase near the end of life of a Sun-like star. This nebula’s dying central star may have produced the outer circular concentric shells by shrugging off outer layers in a series of regular convulsions. The formation of the beautiful, complex-yet-symmetric inner structures, however, is not well understood. The featured image is a composite of a digitally sharpened Hubble Space Telescope image with X-ray light captured by the orbiting Chandra Observatory. The exquisite floating space statue spans over half a light-year across. Of course, gazing into this Cat’s Eye, humanity may well be seeing the fate of our sun, destined to enter its own planetary nebula phase of evolution … in about 5 billion years.

JWST Breaks New Ground - Twice

Between the orbit of Jupiter and Saturn lies a small 151Km wide asteroid/minor planet called Chariklo. This left over from our early solar system hasn't been imaged before, and was too small for JWST to image too, however, the JWST team were waiting for an opportunity to do some science.

Because of it's size, the only way they could do this was if a star passed directly behind the asteroid from the location of JWST, so it was put on a watch list, and in October, this is exactly what happened.

This is the first time any telescope has been able to see an object it wouldn't ordinarily be able to image, simply due to a chance occultation, so marks a first and interesting method for looking at some of these far off objects.

The asteroid happens also happens to sport a small ring of debris, and as the star didn't quite make a direct occultation, it did pass through the debris rings, being picked up twice as it passed through.

But what really was impressive was the second bit of data gathered, as the occultation occurred JWST was able to record the composition, detecting water ice.

Up until now, it had been assumed that the asteroid would have a significant water ice component, but this is the first time anybody has been able to take some real data from it.

Objects like Chariklo tell us so much about the early solar system, how Earth got it's water, and what other systems and exoplanets are likely made from.
