NASA scientists have taken a breathtaking image of jellyfish-shaped Nebula using Chandra X-ray observatory. In the image we can clearly see a gigantic yellow coloured jellyfish floating in the dark sky along with millions of twinkling stars. According to NASA that tweeted the image on official twitter account, jellyfish Nebula is an interstellar cloud on hydrogen, helium, dust and other ionised gases.
Officially named as IC 443, the jellyfish-shaped nebula is the remnant of a supernova located in the constellation Gemini that is nearly 5,000 light years from Earth.
According to NASA, new observations by Chandra X-ray Observatory show that the explosion that created the Jellyfish Nebula may have also formed a peculiar object located on the southern edge of the remnant, called CXOU J061705.3+222127, or J0617 for short. The object is likely a rapidly spinning neutron star, or pulsar.
When a massive star runs out of thermonuclear fuel, it implodes, forming a dense stellar core called a neutron star. The outer layers of the star collapse toward the neutron star then bounce outward in a supernova explosion. A spinning neutron star that produces a beam of radiation is called a pulsar. The radiation sweeps by like a beacon of light from a lighthouse and can be detected as pulses of radio waves and other types of radiation.
This new composite image includes a wide-field view from an astrophotographer that shows the spectacular filamentary structure of IC 443. Within the inset box, another optical image from the Digitized Sky Survey (red, green, orange, and cyan) has been combined with X-ray data from Chandra (blue). The inset shows a close-up view of the region around J0617.
