Sheldon Rey Boco of the Philippine Jellyfish Stings Project and is currently based at Griffith University in Australia and Mr. The north-eastern shell was probably created by a fast shock wave (100 kilometres per second), whereas the southern shell was probably created by a slow shock wave (30 kilometres per second).Filipino scientists Dr. The differences in colour are also the result of differences in the energies of the shock waves hitting the interstellar medium. The colour differences seen in this image represent different wavelengths of infrared emission. These clumps are part of a molecular cloud which can be seen in this image as the greenish cloud cutting across IC 443 from the north-west to south-east. The smaller southern shell, seen here in a bright cyan colour on the bottom half of the image, is constructed of denser clumps and knots primarily emitting light from hydrogen gas and heated dust. The larger north-eastern shell, seen here as the violet-coloured semi-circle on the top left of the supernova remnant, is composed of sheet-like filaments that are emitting light from iron, neon, silicon and oxygen gas atoms and dust particles heated by the blast from the supernova. What is unusual about the IC 443 is that its shell-like form has two halves that have different radii, structures and emissions. The blast from the supernova sent out shock waves that travelled through space, sweeping up and heating the surrounding gas and dust in the interstellar medium, and creating the supernova remnant seen in this image. IC 443 is the remains of a star that went supernova somewhere between 5,000 and 10,000 years ago. This oddly colourful nebula is the supernova remnant IC 443. The cloud crosses the entire nebula from northwest to southeast. In both optical and X-ray wavelengths, nebula’s emission is heavily absorbed by a huge molecular cloud located in the foreground. X-ray images reveal the nebula as centrally peaked, with a barely visible soft X-ray shell. The larger shell is part of a different supernova remnant, designated as G189.6+3.3. There is a third shell which is larger but, even though it was once believed to be part of the Jellyfish Nebula, it is now known to be older, with an estimated age of about 100,000 years. Image:NASA/DOE/Fermi LAT Collaboration, NOAO/AURA/NSF, JPL-Caltech/UCLA Cyan loops indicate where the remnant is interacting with a dense cloud of interstellar gas. Fermi GeV gamma-ray emission is shown in magenta, optical wavelengths as yellow, and infrared data from NASA’s Wide-field Infrared Survey Explorer (WISE) mission is shown as blue (3.4 microns), cyan (4.6 microns), green (12 microns) and red (22 microns). This multiwavelength composite shows the supernova remnant IC 443, also known as the Jellyfish Nebula. The smaller southern shell, which was probably created by a shock wave moving at about 30 km/s, is composed of denser clumps that emit light mainly from hydrogen gas and hot dust. It consists of complex filaments that are emitting light from iron, neon, silicon and oxygen atoms and dust particles, which are heated by the blast from the supernova event. The larger northeastern shell was likely created by a shock wave travelling at about 100 km/s.

In optical and radio wavelengths, the nebula appears shell-like and is composed of two sub-shells with different radii, emissions and centres. The nebula’s expansion to the west is exaggerated, while the expansion to the east is experiencing a compression effect. In the southeastern portion of the nebula, the molecular cloud is very dense and clumpy, and the nebula’s gas appears ring-like, while the northeastern part of the nebula is interacting with a wall of neutral hydrogen, a considerably less dense environment that allows the shock to travel at a much higher velocity. The interaction with the cloud has affected the nebula’s morphology. The remnant has evolved in the complex environment of the molecular cloud in which the progenitor star was still embedded when it ended its life. IC 443 is interacting with the surrounding molecular clouds and is one of the most studied supernova remnants in the sky.

It has a spatial diameter of about 70 light years, or 20 parsecs.
