Latest Supergiant 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.
Supernovae are important astronomical objects. They tell us about how stars die and are used as measuring sticks to investigate distant galaxies. But there is still some uncertainty as to how the supernova process proceeds in some cases.
A new image released by the European Space Agency shows multiple arcs around Betelgeuse, the nearest red supergiant star to Earth.
A team of Japanese researchers has discovered evidence that a yellow supergiant was, in fact, the progenitor for a recently discovered supernova -- a discovery which they say raises serious questions regarding our understanding of the evolution of massive stars.
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.
A massive bright reddish star in the Orion constellation has mysteriously shrunk by over 15 percent in the last 15 years.
NASA's Hubble Space Telescope has identified a star that was one million times brighter than the sun before it exploded as a supernova in 2005.
By analyzing a series of images, researchers from the Dark Cosmology Centre at the Niels Bohr Institute, University of Copenhagen and from Queens University, Belfast have proven that two dying red supergiant stars produced supernovae.
Almost two months ago my newborn son began his life just as stars go through a life cycle of their own. Stars are formed from within a nebula, a cloud of gas and dust.
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...
