But a team using the Very Large Telescope (VLT) in Chile says the cause was almost certainly a giant dust cloud between us and the star.

Close to Earth, relatively speaking, at a distance of about 550 light-years, Betelgeuse is what's known as a semi-regular variable star.

Perhaps there was a large cool spot on the surface of the star, because red supergiants like Betelgeuse are known to have very large convective cells that can cause hot spots and cold spots.

Or maybe there was a cloud of dust forming right in front of the star as viewed from Earth.

"Our overall idea is that there was a cool spot on the star which, because of the local drop in temperature, then caused gas ejected previously to condense into dust," she told BBC News.

"So, the cool spot on the surface would initially make the star look dimmer to us.

Emily Cannon said: "I don't think this event means Betelgeuse is going to go supernova anytime soon, even though that would be incredibly interesting and I was kind of wishing it myself.

"We know that red supergiants can display increased mass loss rates, which may indicate there's a later stage in their lives when they are more likely to go supernova?

The last supernova observed in our Milky Way Galaxy was Kepler's Star, which was observed in 1604.

The Hubble Space Telescope has been hit with computer trouble, with all astronomical viewing halted, NASA said Wednesday.
