And later today, Jupiter will make the solar system's largest jack-o'-lantern face, thanks to shadows from two of its moons! Check it out in our "Eyes on the Solar System" 3D simulator: go.nasa.gov/3DBbMLq

A screenshot of a web application shows a simulated view of the planet Jupiter, where two fuzzy, circular shadows cast on the planet almost appear to form the eyes of a face. Also visible are the on-screen controls of the Eyes on the Solar System simulation software.

Tricks and Treats: This #Halloween, treat yourself to some strange – and sometimes sweet – sights and sounds from space.

A nebula glows brightly against the darkness of space in an image from the Hubble Space Telescope. This planetary nebula is the relic of a dying, Sun-like star. The nebula's glowing gas forms several visually interlocking rings in an hourglass shape. Where the rings meet at the center of the nebula, smaller circles of gas appear to take the form of a single human eye, open wide. The entire formation appears to be glaring at the viewer.

Well, the largest one at the moment. Here's the Sun in 2014, as seen by

's Solar Dynamics Observatory. solarsystem.nasa.gov/resources/387/

Several photos of active regions on the Sun combined to look something like a jack-o-lantern’s face. Against the darkness of space, the Sun glows a deep orange color, with some areas glowing more brightly. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the Sun’s atmosphere, the corona.

Say cheese!

Today, NASA’s Solar Dynamics Observatory caught the Sun "smiling." Seen in ultraviolet light, these dark patches on the Sun are known as coronal holes and are regions where fast solar wind gushes out into space.

Satellite imagery from NASA's Solar Dynamics Observatory shows the Sun in ultraviolet light colorized in light brown. Dark patches on the Sun's surface are in the shape of a smile.

And through a telescope, it was fun to see it ! Here a movie spanning 20 minutes of the planet rotation, taken with a 180 mm Maksutov telescope, from France.

Kinda looks more like Caillou.
