4/5 That’s not all, Webb also captured seven of Neptune's 14 known moons. A very bright point of light seen in Webb’s images is Neptune's large and unusual moon, Triton. It is covered in frozen, condensed nitrogen and reflects 70% of the sunlight that hits it. That’s why it appeared very bright to Webb. (Nasa)

5/5 Neptune planet was discovered in 1846 and since then it has always fascinated researchers. The planet is located 30 times farther from the Sun than Earth and hence, its orbits are in the remote, dark region of the outer solar system. According to Nasa, the Sun is so farther from Neptune that high noon is similar to a dim twilight on Earth. (NASA, ESA, CSA, STScI)

The James Webb Space Telescope has been shocking us with its capabilities ever since its launch. NASA's $10 billion space telescope has been capturing breathtaking images of far-off galaxies, star clusters, black holes and more. In effect, it is looking back in time to hundreds of millions of years ago. Now, the telescope has achieved yet another feat by looking back in time and capturing a stunning image of crashing galaxies, which occurred more than 270 million years ago.

ESA has released the mesmerizing image which shows an entwined pair of galaxies from the constellation Cetus around 270 million years ago. The JWST is co-managed by NASA and ESA. ESA explained in a blog below the image, “The two galaxies in IC 1623 are plunging headlong into one another in a process known as a galaxy merger. Their collision has ignited a frenzied spate of star formation known as a starburst, creating new stars at a rate more than twenty times that of the Milky Way galaxy. ”

Although this same galaxy was previously captured by the Hubble Space Telescope, the JWST's infrared capturing instruments are far more technologically advanced which helped capture this stunning image. The team of scientists captured the image across the infrared portions of the electromagnetic system with the help of JWST's MIRI, NIRSpec, and NIRCam instruments.

JWST in trouble

Just a few months ago, the James Webb Space Telescope encountered trouble with one of its instruments. According to NASA, the Mid-Infrared Instrument aboard the JWST is not functioning optimally due to an issue with one of its four observing modes. NASA said in a blog, “On Aug. 24, a mechanism that supports one of these modes, known as medium-resolution spectroscopy (MRS), exhibited what appears to be increased friction during setup for a science observation.”

This is not the first time that the $10 billion space telescope has encountered issues during operation. In June, the telescope was hit by a meteoroid which caused some damage to one of the telescope's 18 mirror fragments which required correction by NASA to compensate for the damage.
