Latest Betelgeuse Stories
In a discovery decades in the making, scientists have detected the first of a “theoretical” class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna Żytkow.
Astronomers using the European Southern Observatory’s (ESO) Very Large Telescope have discovered the largest yellow star so far. The discovery is of a yellow hypergiant star located about 12,000 light years away.
Astronomers have snapped a very detailed image of the outer atmosphere of the red supergiant Betelgeuse.
A new image released by the European Space Agency shows multiple arcs around Betelgeuse, the nearest red supergiant star to Earth.
New image reveals vast nebula around famous supergiant star.
Just like out of a good science fiction setting on some far-off planet, our own Earth could soon have a second sun, but only for a limited time.
An international team of astronomers, led by Keiichi Ohnaka at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, has made the most high resolution images of a dying giant star to date.
Using different state-of-the-art techniques on ESO's Very Large Telescope, two independent teams of astronomers have obtained the sharpest ever views of the supergiant star Betelgeuse.
A massive bright reddish star in the Orion constellation has mysteriously shrunk by over 15 percent in the last 15 years.
Astronomers have discovered three giant stars in the Milky Way, an international conference was told. The three "red giants" were found among a group of 74 stars studied by a group of international astronomers.
Supergiant Star -- A star of 15 solar masses exhausts its hydrogen in about one-thousandth the lifetime of our sun. It proceeds through the red giant phase, but when it reaches the triple-alpha process of nuclear fusion, it continues to burn for a time and expands to an even larger volume. The much brighter, but still reddened star is called a red supergiant. Betelgeuse, at the shoulder of Orion, is the best-known example. Absolute luminosities may reach -10 magnitude compared to +5...
