"Jupiter's Eye"

The black spot which simulates a giant eye on the surface of Jupiter was actually just a well-timed shadow, captured by one of Hubble’s cameras as Jupiter’s moon Ganymede passed by the planet's famed Great Red Spot.

Pismis 24 !

The small open star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 in Scorpius, about 8,000 light-years away from Earth.

The brightest object in the picture is designated Pismis 24-1. It was once thought to weigh as much as 200 to 300 solar masses. This would not only have made it by far the most massive known star in the galaxy, but would have put it considerably above the currently believed upper mass limit of about 150 solar masses for individual stars.

However, Hubble Space Telescope high-resolution images of the star show that it is really two stars orbiting one another. They are estimated to each be 100 solar masses.
