VIVA – group scientist have found nova fastest ever recorded, Arizona State University announced it this month.
This discovery has been observed since June 12, 2021 after nova Hercules V1674 released an explosion so bright that it can be seen from Earth with binoculars or even the naked eye.
For information, A nova is created due to white dwarf (dead star) which absorbs the material of a companion star that is close to it.
Over time, the tiny star sucks matter from its companion star, causing it to fall onto the white dwarf and cause it to heat up.
This heat then causes an explosive reaction that launches matter at nearly the speed of light and releases a burst of energy known as a nova.
Experts from Arizona State University hope their observations will help answer bigger questions about the chemistry of our solar system, the death of stars and the evolution of the universe.
Launching from BGR, here are 4 facts about the fastest nova ever recorded by scientists:
–
1. Fade in a day
Usually, when a nova forms it takes weeks or longer for the bright burst of light from the nova to fade. However, according to the researchers’ explanation, the Hercules V1674 nova has faded in about a day, beating the previous nova that disappeared for three days.
2. Fastest Nova
The fastest nova ever recorded by scientists took several days to fade. This makes nova Hercules V1674 said to be a rare event because this nova only fades within a day. The event left a deep impression on researchers and led them to believe it was the fastest nova ever recorded.
3. Emit an echo
However, fading fast isn’t the only thing extraordinary about this system, surprisingly the energy and light output of the Hercules V1674 emits a gong-like echo when struck.
4. It shakes every 501 seconds
In addition, the shaking that occurs in the nova every 501 seconds can be seen in both visible light and X-ray. The researchers also revealed that when a nova explosion ejects material, the outflow is shaped by winds that appear to depend on the white dwarf’s position.
This is something that scientists still don’t fully understand. But by learning a little about this cosmic phenomenon, it is hoped that we can understand the universe around us and even learn more about how life formed on earth.
