Stunning image of Antares, a red supergiant star 850 times the diameter of our Sun, surrounded by a yellowish nebula. The image also shows the globular star cluster M4 and the star Al Niyat. The nebula glows due to radiation from Antares' blue companion star.

A stunning image of Betelgeuse, a red supergiant star in the Orion constellation. The image, captured by the Very Large Telescope, reveals a massive plume of gas surrounding the star, showcasing its shedding mass as it approaches the end of its life. The colors range from deep blues and purples to a bright, central white light. Betelgeuse is expected to become a supernova within the next few thousand years.
