Milky Way’s Stellar Halo is At Least Two Million Light-Years Across

Jan 16, 2023 by News Staff

Astronomers from the University of California, Santa Cruz and elsewhere have discovered 208 new RR Lyrae variable stars in the halo of our Milky Way Galaxy;...

This Hubble image shows the globular cluster Messier 3. The color image was made from separate exposures taken in the visible and ultraviolet regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Five filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This image from ESO’s VISTA telescope shows the central part of the Milky Way. While normally hidden behind obscuring dust, the infrared capabilities of the telescope allow astronomers to study stars close to the Galactic center. Within this field of view astronomers detected several RR Lyrae stars. Image credit: ESO / VVV Survey / D. Minniti et al.
