This frame from an animation shows five versions of observations that NASA Curiosity made about one hour apart while Mercury was passing in front of the sun on June 3, 2014. Two sunspots, each about the diameter of Earth, also appear.
Ver en NASA ↗NASA Kepler mission has discovered a world where two suns set over the horizon instead of just one. The planet, called Kepler-16b, is the most Tatooine-like planet yet found in our galaxy and is depicted here in this artist concept.
Ver en NASA ↗These images, from 8 April 2003 show that depending upon the position of the Sun, the solar power stations in California Mohave Desert can reflect solar energy from their large, mirror-like surfaces directly toward one of NASA Terra cameras.

Ver en NASA ↗The sun featured just one, rather small active region over the past few days, but it developed rapidly and sported a lot of magnetic activity in just one day (Apr. 11-12, 2018) as observed by NASA's Solar Dynamics Observatory.
Ver en NASA ↗An active region at the sun edge produced several M5-class medium sized flares over a ten-hour period on Apr. 3, 2017, as seen by NASA's Solar Dynamics Observatory.
Ver en NASA ↗When an active region rotated over to the edge of the sun, it presented NASA's Solar Dynamics Observatory with a nice profile view of its elongated loops stretching and swaying above it Mar. 8-9, 2017.
