Gigantic bubbles boiling on the surface of star Betelgeuse
Giant star Betelgeuse shed the equivalent mass of the Earth every year but how do it does is not properly understood. Using state of the art imaging techniques, astronomers have revealed a vast plume of gas and gigantic bubbles boiling on the surface of star Betelgeuse. The new technique will provide clues to how they shed the mass?
The images show that the whole outer shell of the star is not shedding material evenly in all directions, which may be due to either large scale gas motions caused by heating, or because of the star's rotation. Betelgeuse's atmosphere is bouncing vigorously up and down in bubbles that are as large as the supergiant star itself, and could be responsible for the ejection of the massive plume into space.
Betelgeuse is the nearest star to Earth.

Big Planet, Small Star
One of the smallest stars in the Galaxy has been found to have a planet orbiting it that is six times more massive than Jupiter. This gas giant is as far from its star as Mercury is from our Sun, but because the star is so small, it is like a scaled...

Rocky Earthlike Planet Discovered
Researchers on 21.4.09 confirmed the existence of a rocky Earthlike planet with a mass of 1.9 Earth masses, orbiting in the Gliese 581 system. Another planet in the four planet system was also found to be lying in the star's habitable zone, the...

A Large Planet Orbiting A Small Star
An artist's conception of the planetary system. Astrometry, a 50 year old technique used to find exoplanets, planets around other stars, has finally succeeded. Planets outside the solar system are nearly impossible to see, so the method relies on...
