What it is: The spiral nebula IC 2163 (left) and NGC 2207 (right)
Where it is: 80 million light-years away, in the constellation Canis Major
When it was shared: Oct. 31, 2024
Why it’s so unique: This spooky scene, a composite of images recorded by both the James Webb Space Telescope (JWST) and the Hubble Space Telescope, includes a set of spiral nebula with intense cores that look like a scary set of “blood-soaked” eyes. These galaxies grazed each other countless years back and are presently clashing.
That’s since countless years earlier, the smaller sized spiral nebula left wing, IC 2163, gradually sneaked behind the bigger spiral nebula on the right, NGC 2207. Due to the fact that of their close encounter, the galaxies’spiral arms might have established small, tail-like extensions, both in between IC 2163’s core and its far left arm and in between the 2 galaxies’intense cores. Another comparable extension stretches from the top of the bigger spiral, which is wandering away from the spooky scene.
The 2 galaxies’products might have likewise clashed throughout the graze, which may describe the thick and bulging arms, consisting of the “eyelid” areas, highlighted in brilliant red.

Both galaxies are effective star factories, producing almost 2 lots brand-new sunlike stars each year. This star development rate is much greater than that of the Milky Way, which produces just 2 or 3 brand-new sunlike stars every year. And while our galaxy produces one supernova every 50 years, both of these galaxies have actually hosted 7 recognized supernovas in current years. These supernovas might have sustained brand-new star development by cleaning out area in the galaxy’s spiral arms, therefore rearranging gas and dust. When the product cooled off, brand-new stars might form.
This exceptionally comprehensive image integrates mid-infrared observations from JWST with ultraviolet and visible-light observations from Hubble.
The star-forming areas spread throughout the spiral arms are represented in brilliant blue in the Hubble information and in pink and white in the JWST information. The locations with big groups of stars are very star clusters. A few of the brilliant areas may likewise be mini-starbursts, in which stars type at an incredibly high rate.
What’s next? Throughout countless years, the orbits of these galaxies will end up being tighter, and they will continue to swing previous each other in a magnificent cosmic dance. As they inch closer to each other, they will combine into a single galaxy with improved arms and a single brighter core. In the next billion years or so, this spooky scene will have a single “eye.”
