The James Clerk Maxwell Telescope (JCMT), based in Hawaii, discovered a stellar glow 1
"A discovery of this magnitude could only have taken place in Hawaii," said Dr. Steve Mairs, an astronomer and chief investigator of the team that discovered the stellar blast. "Using the JCMT, we study the birth of neighboring stars as a means of understanding the history of our own solar system. Letting rockets around the younger stars is a new territory and provides us with key information about the physical conditions of these systems. of the ways we are working to respond to people's most lasting questions about space, time and the universe around us. "
The JCMT Transient Survey team recorded the 1,500 year blaze using the telescope status high frequency radio technology of the art and sophisticated techniques of analysis of the image. Identified by the Dr. Steve Mairs astronomer, the original data were obtained using the JCMT supercooled camera known as "SCUBA-2", which is maintained at a cold -459.5 degrees Fahrenheit.
It is thought that the flare is caused by an interruption in an intense magnetic field by actively channeling the material onto a young and growing star while gaining mass from its surroundings. The event occurred in one of the star-forming regions closest to Earth, the Orion Nebula. It only lasted a matter of hours.
Located near the summit of Maunakea, the JCMT is the largest and only telescope in the northern hemisphere able to make this kind of discovery. The observation of stellar stars was made as part of a monthly monitoring program by researchers from around the world who use the JCMT to observe nearly 1,000 nearby stars in the early stages of their training.
