1998/9 UV HST images of Betelgeuse showing asymmetrical pulsations with corresponding spectral line profiles. Astronomers saw some major advances in astronomical imaging technology in the 1970s, beginning with Antoine Labeyrie's invention of speckle interferometry, a process that significantly reduced the blurring effect caused by astronomical ...
The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun , observed from Earth , stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image.

One of the biggest and brightest stars in the night sky has left astronomers puzzled after it has faded dramatically over the last year. Some have speculated that this is a sign of an impending ...
Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. New examinations of this behemoth star suggest it is both smaller — and closer — than astronomers ...
Models indicate that even rapidly rotating main-sequence stars should be braked by their mass loss so that red supergiants hardly rotate at all. Those red supergiants such as Betelgeuse that do have modest rates of rotation may have acquired it after reaching the red supergiant stage, perhaps through binary interaction. The cores of red ...
−119 [d] or ~R Betelgeuse: L/T eff & AD Widely recognised as being among the largest known stars. [21] Might be the largest star visible to the naked eye. [30] The higher radii estimate assume Mu Cephei is in the Cepheus OB2 OB association. [28] [31] Other sources suggest Mu Cephei and Betelgeuse are likely similar in properties.
In "Beetlejuice Beetlejuice," Delia Deetz (Catherine O'Hara), Lydia Deetz (Winona Ryder) and Lydia's daughter Astrid (Jenna Ortega) return to the fictional town of Winter River after a family tragedy.
