This composite image shows the size and location of the Smith Cloud on the sky. The cloud is 15 degrees across in angular size - the width of an outstretched hand at arm’s length. The apparent size of the full Moon is added for comparison. The Smith Cloud appears in false-color, radio wavelengths. The visible-light image of the background star field shows the cloud’s location in the direction of the summer constellation Aquila. Image credit: NASA / ESA / Z. Levay, STScI / B. Saxton / F.

Left: a ground-based view of the Milky Way’s central bulge; giant dust clouds block most of the starlight coming from the galactic center. The Hubble Space Telescope, however, peered through a region (marked by the arrow) called the Sagittarius Window, which offers a keyhole view into the galaxy’s hub. Upper right: this is a small section of Hubble’s view of the dense collection of stars crammed together in the galactic bulge. Lower right: a sample of 4 out of the 70 brightest white dwarfs spied by Hubble in the Milky Way Galaxy’s central bulge. The numbers in the inset images correspond to the stars’ location in the larger Hubble view. Image credit: NASA / ESA / A. Calamida & K. Sahu, STScI / SWEEPS Science Team / A. Fujii.

The upper two panels of this graphic represent a possible explanation for a recent increase in X-ray flares from Sagittarius A* seen by three X-ray telescopes. As part of a long monitoring campaign, astronomers observed the black hole as a mysterious object called G2 appeared to pass close to the black hole. The timing of G2’s passage could suggest that material from G2 caused the surge in X-ray activity, but it is also possible that this unrelated behavior of Sagittarius A*. The bottom panel is a view of the region around the black hole where red, green, and blue represent low, medium, and high-energy X-rays detected by NASA’s Chandra X-ray Observatory. Sagittarius A* itself is not visible in this image, but is embedded in the white dot at the end of the arrow. Image credit: NASA / CXC / MPE / G.Ponti et al. / M.Weiss.

This image shows the Sculptor Dwarf Galaxy, a close neighbor of our own Milky Way Galaxy. Despite their proximity, both galaxies have very distinct histories and characters. This galaxy is much smaller, fainter and older than the Milky Way and appears here as a cloud of faint stars filling most of the image. Many other much more distant galaxies can be seen shining right through the sparse stars of the galaxy. Image credit: ESO.
