Hubble s Lagoon
2.10.2010

Like brush strokes on a canvas, ridges of color seem to flow across this scene. But here, the canvas is nearly 3 light-years wide and the colors map emission from ionized gas in the Lagoon Nebula, recorded by the Hubble Space Telescope's Advanced Camera for Surveys.

The Belt of Venus over the Valley of the Moon

The brilliant full Moon might not look quite like this to skygazers next Monday, but the image is a mosaic of 18 digital frames recorded when the Moon was only about seven hours past its exact full phase or time of maximum illumination as viewed from Earth.

Martian Sunset
10.01.2009

This month, the Mars Exploration Rovers are celebrating their 5th anniversary of operations on the surface of the Red Planet. The serene sunset view, part of their extensive legacy of images from the martian surface, was recorded by the Spirit rover on May 19, 2005.

Blue Sun Bursting
20.05.2013

Our Sun is not a giant blueberry. Our Sun can be made to appear similar to the diminutive fruit, however, by imaging it in a specific color of extreme violet light called CaK that is emitted by the very slight abundance of ionized Calcium in the Sun's atmosphere, and then false color-inverting the image.
