| A massive explosion spotted 200 light years from Earth has baffled astronomers. The strange spot, nicknamed the cow, is 100 times brighter than a supernova and is growing at an incredible rate, but scientists have no idea what triggered it (stock image) |
- The blast appeared in a distant galaxy but scientists are unsure what triggered it
- They theorise the flash is a 9,000°C (16,000°F) cloud of high-energy particles
- It is bursting outwards at an incredible speed of 12,000 miles per second
- One researcher said 'there hasn't really been another object like this'
