It is the most massive star that has a Bayer designation. It was only discovered to be (at least) two stars in the past few decades. Both the obscuring clouds and the great distances also make it difficult to judge whether the star is just a single supermassive object or, instead, a multiple star system. A number of the "stars" listed below may ...
The R136a system at the core of R136 is a dense luminous knot of stars containing at least 12 stars, [11] the most prominent being R136a1, R136a2, and R136a3, all of which are extremely luminous and massive WN5h stars.
A red giant star with one of the largest ranges in brightness known of stars in the night sky visible to the unaided eye. Despite its large radius, it is less massive than the Sun. 119 Tauri (CE Tauri, Ruby Star) 587 – 593 [76] AD ρ Cassiopeiae: 564 ± 67 or 700 ± 112 [77] AD
(most likely value) A recent analysis of the Wilkinson Microwave Anisotropy Probe (WMAP) in 2007 has found an irregularity of the temperature fluctuation of the cosmic microwave background within the vicinity of the constellation Eridanus with analysis found to be 70 microkelvins cooler than the average CMB temperature. One speculation is that ...
Researchers estimate that it could contain somewhere between 1,000 and 10,000 trillion stars. Skip to main content. 24/7 Help. For premium support please call: 800-290-4726 more ways to reach us ...
The James Webb Space Telescope has helped demystify the strange 2009 observation of a giant star about 25 times more massive than the sun that appeared to disappear from existence.
WOH G64 (IRAS 04553-6825) is a symbiotic binary in the Large Magellanic Cloud (LMC), roughly 160,000 light-years from Earth. The main component of this system was once recognized as the best candidate for the largest known star when it was a red supergiant, [7] until it gradually became a yellow hypergiant with half of its original size.
Earlier observations found that, if placed at the center of our solar system, the massive star Betelgeuse would stretch out beyond the orbit of Jupiter. This new study finds its body would only ...
