Recently, researchers have confirmed the detection of a star system that will one day end in a kilonova.
Why in news?
- The newly found star system has been labelled CPD-29 2176 and is located about 11,400 light-years from the earth.
- CPD-29 2176 is currently a neutron star and a star orbiting each other.
What is Kilonova?
- A kilonova is a cosmic event that occurs when a neutron star smashes into another neutron star or a black hole.
- It releases heavy metals like gold, silver, and selenium into outer space at tremendous velocities, as well as radiation.
- A kilonova radiation also accompanies a gamma-ray burst, one of the most energetic cosmic events ever known.
What is a Neutron star?
- The stars which are formed when a massive star runs out of fuel and collapses are called neutron stars
- The very central region of the star – the core – collapses, crushing together every proton and electron into a neutron.
Q1) What is a black hole?
A black hole is a place in space where gravity pulls so much that even light can not get out. Gravity is so strong because matter has been squeezed into a tiny space.
