Two images captured approximately one year apart with the SPHERE instrument on the European Southern Observatory’s Very Large Telescope show the apparent dimming of the star Betelgeuse.
A University of Arizona astronomer has his eye on a mysteriously dimming star in outer space.
Narsi Anugu is a postdoctoral scholar at the UA studying interstellar space. He is focusing on the star Betelgeuse, 642.5 light years from earth. The star's light has been dimming for the past several months, and some scientists speculate it is on the verge of exploding, or going “supernova.” Anugu thinks if that happens, the resulting phenomenon will create a boon for space science.
“This will boost astronomy, clear up many questions about whether astronomy is interesting, and increase funding," he said. "Every astronomer would love to see that.”
Betelgeuse is seen from Earth as part of the popular constellation Orion, the hunter. The star marks the shoulder of the hunter on the left side of the figure to a viewer from Earth. Scientists say whenever Betelgeuse explodes, it will be visible in Earth's daylight sky and would be bright enough to cast shadows at night. But they cautiously add the event might not happen for another 100,000 years.
