Which one of the following best describes the ‘30 Doradus B&rsqu...
Nasa's Chandra X-ray Observatory recently captured a stunning image of 30 Doradus B, a supernova remnant that is part of a vibrant region of space where stars have been forming for millions of years.
About 30 Doradus B:
- 30 Doradus B, also cataloged as NGC 2060, is a supernova remnant found in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way.
- It is part of a large star-forming region where stars have been continuously forming for the past 8 to 10 million years.
- It is a complex landscape of dark clouds of gas, young stars, high-energy shocks, and superheated gas, located 160,000 light-years away from Earth.
What is a Supernova?
- A supernova is the explosion of a star whose luminosity after an eruption suddenly increases many millions of times its normal level.
- Supernovas are "the largest explosion that takes place in space."
- A star can go supernova in one of two ways:
- Type I supernova: The star accumulates matter from a nearby neighbour until a runaway nuclear reaction ignites.
- Type II supernova: The star runs out of nuclear fuel and collapses under its own gravity.
- Supernovas can briefly outshine entire galaxies and radiate more energy than our sun will in its entire lifetime.
- They're also the primary source of heavy elements in the universe.
- They heat up the interstellar medium, distribute heavy elements throughout the Galaxy, and accelerate cosmic rays.
Hence option c is the correct answer.
