Sketch of the relative positions of NASA’s and ESA’s spacecraft that observed the February 12, 2021 coronal mass ejections; ESA’s Solar Orbiter spacecraft was ‘behind’ the Sun from the perspective of Earth; the Earth was about 12 degrees west of Sun-center as seen from Solar Orbiter; ESA’s Proba-2, which orbits the Earth, and the ESA/NASA Solar and Heliospheric Observatory (SOHO), which is located in orbit around the Lagrange point 1, 1.5 million km in front of the Earth towards the Sun, also viewed the coronal mass ejection; NASA’s STEREO-A (Solar Terrestrial Relations Observatory) also caught a glimpse of the event from its viewpoint away from the direct Sun-Earth line; together the spacecraft provide valuable, different perspectives on the same event.

This image, taken by the NASA/ESA Hubble Space Telescope, shows the massive galaxy cluster ACO S 295. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) instruments in the infrared and optical parts of the spectrum. 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 visible-light image of Jupiter was created from data captured on January 11, 2017 using Hubble’s Wide Field Camera 3. Near the top, a long brown feature called a ‘brown barge’ extends 72,000 km (nearly 45,000 miles) in the east-west direction. The Great Red Spot stands out prominently in the lower left, while the smaller feature nicknamed Red Spot Jr. (known to Jovian scientists as Oval BA) appears to its lower right.

This image of the irregular dwarf galaxy Sextans B, taken by the Nicholas U. Mayall 4-m Telescope, features red-colored star-forming regions near the galaxy’s center; surrounding the galaxy are several bright stars that are located much closer to us in our Milky Way Galaxy, identified by the crisscross patterns created by light interacting with the structure of the telescope, as well as numerous fuzzy-looking background galaxies that appear small because they are much farther away than Sextans B.
