New study captures traces of massive supernova explosions in the Milky Way
A Japanese research team recently reported that they used the observation equipment in the International Space Station's Japanese "Hope" experimental capsule to capture the traces of large-scale supernova explosions in the Milky Way for the first time, which will provide clues for studying the evolution of the Milky Way.
According to Japanese media reports, this new achievement was obtained by a research team composed of the Japan Aerospace Research and Development Agency and other agencies. With the help of the all-day X-ray monitoring device carried in the "Hope" experiment module, the researchers observed the existence of gas with a temperature of up to 3 million degrees Celsius at about 5,500 light-years from the earth. This gas is located near Cygnus and has a horseshoe shape with a range of 2,000 light years.
Through detailed analysis of the X-rays from these gases, the researchers found that it contains iron, neon and other components. According to the temperature and distribution of the gas, the gas should be a trace left by a supernova explosion of a star that is dozens of times the mass of the sun. The outbreak is presumed to have occurred between 3 million and 2 million years ago.
Massive stars at the end of their lives do not have enough heat to balance the center of gravity, which will collapse the entire star toward the center, causing a violent explosion, called a supernova explosion. According to reports, the supernova explosions that have captured traces this time are 100 times larger than the normal supernova explosions, and they only occur once every 100,000 to 1 million years in the Milky Way, which is a relatively rare astronomical phenomenon.
