The new research suggests that those who opened deaths of many stars, known to supernovas, there may be many effects on our planet in its distance. Investigating historical incidents of these events can help scientists foretell similar events in the future and prepare for them.
Supernovae happen when the stars are larger than the sun Arrive at the end of their nuclear gas supplies and cannot support themselves against their own gravity. Complete gravitational collapse that results in a Neutron Star OA black holeand also sent a blast of energy and high-speed particles that can travel Star systems and Full galaxies in some cases.
It is estimated that if a supernova explodes within about 30 light-time on our planet, our situation is violent, and all life on earth will disappear. Thus, it is important that if a large star explodes within hundreds of light lights on earth, it cannot be fatal, but the serious changes around us, astronomers say.
“We have ridden in environmental changes in the history of the world,” research authority and research at the Institute of the Arctic and Alpine Research, Robert Brokratridge, said to a statement. Beast that, we see these changes. So, what caused it?
“When adjacent supernovas occur in the future, radiation may have an attractive impact of human society. We must know if environmental changes previously caused.”
Brokratridge is never the first person to consider the possibility of the past and future incidents of supnovas affect Shelter on the ground.
However previous studies focus on physics behind an incident. Instead of doing this, Brokompidge tried to use these empirical evidence theories of such events observed on the ground and in space.
Wood rings hide a record of supernova explosions
First, Brokratridge has become data from a variety of space-intensive telescopes, which has long collected data about supernovas attributes.
It helps researcher a more detailed model of how supernova radiation will interact with Atmosphere on the ground than has been done before.
This new model reveals that a sudden burst of high energy pictures, light particles, from a supernova eats the ground Ozone Layer. This is important because the Ozone Layer heals our planet from harmful radiation from the sun.
Without this shield, solar radiation starts to deplete metdana In the stratosphere, the second lowest layer of the earth’s surroundings. This molecule is a primary land driver Greenhouse Effect. That means methane is reduced, the effect of greenhouse heat to be made, which can cool the earth.
In turn, it results in the land to receive higher energy ultraviolet radiation from the sun, which can be very harmful to life. Thus, Brokratridge predicted the sequence effects of supnova radiation bombs can include Fails to animalsAdds wildfires and global cool.
The fact that the world is not as present under bombardment from radiation from a nearby supernova (phew!) Means this model does not test real-time. Leading the Brokratridge to turn the Geological record of the land to hunt for past incidents.
More useful to scientists Wood rings That can reveal the ancient atmosphere condition. That is because the trees absorb carbon from the surroundings of their trunks, where the rings shaped while the tree growing and the supernova radiation bomber must bring the rise to the ground Radioactive Isotopes to the atmosphere carbon on our planet.
Brokiskidger examines records of wood sponsored for about 15,000 years, found 11 radioactive carbon spikes. The researcher has iliora that these spikes can be equal to 11 times the land worn in Supenova radiation.
“The events we learn, in the world, are at the right time and right,” Brokratridge said.
Now, the scientist cannot be completely confident that these spikes are connected to supernovas.
Another possible cause for these spikes that should be eliminated Solar Flares from the sun. To eliminate this possibility, researchers can examine ring results with wooden results unlocked with other geological sources such as ice cores and sediments from the sea floor.
More investigation into the possible connection between Supernova Radiation and the world’s environment helps people prepare for future events.
This can be more relevant if the more Red giant star known as Betelgeuselocated in about 700 slopes in the distance, go to Supenova. it predicted to happen Within the next 100,000 years.
“As we learn more about our nearby neighbors, the prophecy is true there,” Brokratsridge ended. “This will require further modeling and observing from astrophysicists to fully understand the exposure to the land of events.”
Team research has been published in the June edition of The monthly notifications of the Royal Atronomical society.
