According to ANU cosmologist and astrophysicist Dr. Brad Tucker, astronomers have discovered that old stars switch on and off at a fast pace.
“That’s an amazing reason. It can turn on in hours, not millions or billions of years, just like someone is actually doing a trick with light,” he said. I told Australia.
Dr. Tucker said the stars are white dwarfs, which will eventually become the Sun, which can emit energy from stars near orbit.
“As it is, it ignites this kind of thing and does this. We usually thought it was years, thousands, sometimes or slightly longer, but we used TESS. Then … I could see this flashing, “he said.
“You can actually get a glimpse of how the stars in the system interact.”
