Latest Red 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.
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.
New image reveals vast nebula around famous supergiant star.
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.
A massive bright reddish star in the Orion constellation has mysteriously shrunk by over 15 percent in the last 15 years.
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.
Astronomers have spied a faraway star system that is so unusual, it was one of a kind -- until its discovery helped them pinpoint a second one that was much closer to home.
Twenty years ago next month, the closest and brightest supernova in four centuries lit up the southern sky, wowing astronomers and the public alike.
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...
