This illustration is a speculative representation of the interior of Enceladus with a global ocean between its rocky core and icy crust. The thickness of layers shown here is not to scale. Scientists determined that the slight wobble of the moon as it orbits Saturn is much too large for the moon to be frozen from surface to core. The wobble, technically referred to as a libration, reveals that the crust of Enceladus is disconnected from its rocky interior. Image credit: NASA / JPL-Caltech.

This image shows the Sculptor Dwarf Galaxy, a close neighbor of our own Milky Way Galaxy. Despite their proximity, both galaxies have very distinct histories and characters. This galaxy is much smaller, fainter and older than the Milky Way and appears here as a cloud of faint stars filling most of the image. Many other much more distant galaxies can be seen shining right through the sparse stars of the galaxy. Image credit: ESO.

Astronomers Capture Stunning Image of Sculptor Dwarf Galaxy

This image was taken by NASA’s Solar Dynamics Observatory at 3:12 a.m. EDT on September 13, 2015. The edge of Earth, visible near the top of the frame, appears fuzzy because Earth’s atmosphere blocks different amounts of light at different altitudes. On the left, the Moon’s edge is perfectly crisp, because it has no atmosphere. This image was taken in extreme UV wavelengths of 171 angstroms. Though this light is invisible to our eyes, it is typically colorized in gold. Image credit: NASA / SDO.

This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER’s primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up the planet’s surface.

This image from NASA’s Galileo spacecraft shows Io. There are rugged mountains several miles high, layered materials forming plateaus, and many irregular depressions called volcanic calderas. Several of the dark, flow-like features correspond to hot spots, and may be active lava flows. There are no landforms resembling impact craters, as the volcanism covers the surface with new deposits much more rapidly than the flux of comets and asteroids can create large impact craters. The picture is centered on the side of Io that always faces away from Jupiter; north is to the top. Image credit: NASA / JPL / University of Arizona.
