The view of the Galactic center observed with the NIRC2 instrument on the Keck II telescope at the W.M. Keck Observatory. This image is high-pass filtered and shows the position of several S stars close to Sgr A*, which is indicated by a black cross. The star in the white dashed circle shows a magnitude of 16.3 mag, while the star in the blue circle is 17 mag faint. Here north is up and east is to the left.

This composite image shows the Tarantula Nebula. The background image, taken in the infrared, is itself a composite: it was captured by the HAWK-I instrument on ESO’s Very Large Telescope (VLT) and the Visible and Infrared Survey Telescope for Astronomy (VISTA), shows bright stars and light, pinkish clouds of hot gas. The bright red-yellow streaks that have been superimposed on the image come from radio observations taken by the ALMA, revealing regions of cold, dense gas which have the potential to collapse and form stars. The unique web-like structure of the gas clouds led astronomers to the nebula’s spidery nickname. Image credit: ESO / ALMA / NAOJ / NRAO / Wong et al. / M.-R.
