Astronomers have a first detailed view of a mysterious object of the Milky Way called 'The Accident' (temporarily translated as 'accidental') and discovered that it was even confusing More than previous studies <: 00/2: 19 male nammou simulate the mysterious "The Accident" of the Milky Way. It's not entirely a star, and is not a planet - but it Flying through the Milky Way, much closer than what we think. According to a study published on June 30, the Astrophysical Journal Letters magazine, "The Accident" is something in the middle , a rare object called brown dwarfs, or a "star failure". According to Brittanica, brown dwarfs can be 80 times larger than Jupiter, but they only contain a very small part compared to the mass of the face Heaven on earth. Astronomers suspect that this object started life like stars but did not accumulate enough mass to maintain the nuclear synthesis reaction in their core; Instead, brown dwarfs slowly cool and dim in millions or billions of years
. "The Accident" made the scientist confused after unexpected discovery, it was not like a typical brown dwarf . The object appeared faded at some infrared wavelengths, showing it was an old and very cold brown dwarf, but it appeared on the other wavelengths, showing it to be a young brown dwarf , Warm. This contradiction makes the astronomers confused and continue to learn with NASA's Hubble and Spitzer space telescopes, as well as the infrared telescope at WM Keck Observatory in Hawaii
With this additional data, researchers have learned that "The Accident" is even more strange than what they think ago. Located about 50 light, "The Accident" launches through Thien Our Ha is about 800,000 km / h, much faster than a typical brown dwarf. According to astronomers, this fact means "The Accident" has been very long and has been gravitationally given to the larger objects pushing around in billions of years, increasing its movement speed . Based on the wavelength of infrared light due to "The Accident" emits, astronomers know that this object contains less methane gas, a common gas in the brown dwarfs. Methane scarcity shows The original object was formed from 10 to 13 billion years ago, when the Milky Way contained almost completely hydrogen and helium but less carbon. (Carbon appears later, when the oldest stars exploded and spread this element throughout the galaxy). Hey Thuutheo Live Science . Dịch vụ:
