This artist’s impression shows ‘Oumuamua, the first interstellar object discovered in our Solar System. Recent observations show that the object is moving faster than predicted while leaving the Solar System. Astronomers assume that venting material from its surface due to solar heating is responsible for this behavior. This outgassing can be seen in this artist’s impression as a subtle cloud being ejected from the side of the object facing the Sun. Image credit: NASA / ESA / Hubble / ESO / M. Kornmesser.

This Hubble image shows the globular stellar cluster Messier 28. The image is a composite of separate exposures acquired by Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). Seven filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This composite image shows the starburst galaxy Messier 82. The magnetic field detected by SOFIA, shown as streamlines, appears to follow the bipolar outflows (red) generated by the intense nuclear starburst. The image combines visible starlight (gray) and a tracing of hydrogen gas (red) from the Kitt Peak Observatory, with near-infrared and mid-infrared starlight and dust (yellow) from SOFIA and NASA’s Spitzer Space Telescope.
