XX Trianguli, a bright K0-type giant star in a binary system located in the constellation of Triangulum, exhibits chaotic, non-periodic star spot behavior,...
Astronomers using the Center for High Angular Resolution Astronomy (CHARA) Array have observed Polaris, a member of a triple system and the nearest and...
Astronomers using the Karl G. Jansky Very Large Array have observed long-lasting aurora-like radio bursts above a sunspot. This discovery could help us...
Using spectral data from Webb’s Near-Infrared Spectrograph (NIRSpec), astronomers determined that the warm super-Earth Gliese 486b either has a water-rich...
Using NASA’s Neutron star Interior Composition Explorer (NICER), astronomers have observed the merging of multimillion-degree X-ray spots on the surface...
A new paper published in the Astrophysical Journal Letters points to the changes in the photosphere of the red supergiant star Betelgeuse as the source...
Using several instruments on ESO’s Very Large Telescope, VLT Survey Telescope and the New Technology Telescope, astronomers have discovered giant spots...
Our Sun rotates faster at its equator than at its poles. This process is known as differential rotation and is seen in the motion of sunspots. Now, a team...
Astronomers have discovered that a giant star called R Sculptoris is surrounded by giant ‘clumps’ of stellar dust that are peeling away from the shedding...
Zeta Puppis, also known as Naos, is a blue supergiant star, one of the most luminous stars in our Milky Way Galaxy. It is about 60 times more massive than...
The Sun’s nearest stellar neighbor, Proxima Centauri, has a regular cycle of starspots, according to a team of astronomers from the Harvard-Smithsonian...
An international group of astronomers led by Dr. Rachael Roettenbacher from the University of Michigan has used cutting-edge techniques to create direct...
A team of astronomers at the Leibniz Institute for Astrophysics Potsdam, Germany, has created a video that shows the evolution of stellar spots on the...
