Astronomers Discover Bizarre Type Of Hybrid Star
2014-06-05 03:57:41

CU-Boulder 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. Thorne-Żytkow objects (TŻOs) are hybrids of red supergiant and neutron stars that superficially resemble normal red supergiants, such as Betelgeuse in the constellation Orion. They differ, however, in their distinct chemical signatures that result from unique activity in their stellar...

Astronomers Discover Hypergiant Star 1300 Times The Size Of Our Sun

[ Watch the Video: Artist's Impression of Yellow Hypergiant Star HR 5171 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the European Southern Observatory’s (ESO) Very Large Telescope have discovered the largest yellow star so far. The team discovered yellow hypergiant star HR 5171 in a double star system about 12,000 light-years away from Earth. The star is so huge that it can just about be seen with the naked eye, despite its distance from Earth. “The...

New Image Of Betelgeuse Reveals Hot Spots

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have snapped a very detailed image of the outer atmosphere of the red supergiant Betelgeuse. This star is the nearest red supergiant to Earth, easily visible to the unaided eye sitting on the top left shoulder of Orion the Hunter. Betelgeuse is about 1,000 times larger than our Sun and lies about 650 light years away from Earth. Astronomers took a new image with the e-MERLIN radio telescope array operated from the...

Betelgeuse Heading For Collision In 5,000 Years
2013-01-22 12:44:17

Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Agency (ESA) shows multiple arcs around Betelgeuse, the nearest red supergiant star to Earth. Betelgeuse and its arc-shaped shields could be colliding with a dusty "wall" in the next 5,000 years, according to ESA. The red supergiant star sits at the constellation Orion the Hunter, and can easily be seen with the naked eye in the northern hemisphere winter night sky as an orange-red star to...

New image reveals vast nebula around famous supergiant star Using the VISIR instrument on ESO's Very Large Telescope (VLT), astronomers have imaged a complex and bright nebula around the supergiant star Betelgeuse in greater detail than ever before. This structure, which resembles flames emanating from the star, is formed as the behemoth sheds its material into space. Betelgeuse, a red supergiant in the constellation of Orion, is one of the brightest stars in the night sky. It is also one of...

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. The cosmic phenomenon will occur when one of the brightest stars in our night sky suffers a cataclysmic event -- exploding into a supernova. The supergiant red star Betelgeuse in Orion's nebula is predicted to explode, with the impending supernova possibly even reaching Earth. According to a report released Saturday, the most spectacular light...

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. For the first time they could show how the gas is moving in different areas over the surface of a distant star. This was made possible by combining three 1.8 meter telescopes as an interferometer, giving the astronomers the resolving power of a virtual, gigantic 48 meter telescope. Using the ESO VLT...

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. They show that the star has a vast plume of gas almost as large as our Solar System and a gigantic bubble boiling on its surface. These discoveries provide important clues to help explain how these mammoths shed material at such a tremendous rate. Betelgeuse "” the second brightest star in the...

A study released on Tuesday showed that a massive bright reddish star in the Orion constellation has mysteriously shrunk by over 15 percent in the last 15 years and astronomers have not yet determined the cause, AFP reported. The supergiant star Betelgeuse, which is among the eight brightest stars in our sky, is so large that it would reach to Jupiter's orbit in our solar system. But the star has shrunk at a radius of about five astronomical units in size since 1993 by a distance equivalent...

SAN DIEGO, United States (AFP) -- 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. All are approaching the end of their life cycle and very cold, bright and enormous, said Philip Massey of the Lowell telescope in Flagstaff, Arizona. The Red Giants are the largest stars ever observed. Each is 1,500 times that of our sun. The stars...

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...
