This Hubble image reveals a detailed view of part of the dwarf elliptical galaxy Messier 110. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Wide Field Planetary Camera 2 (WFPC2). It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This artist’s concept of a lake at the north pole of Titan illustrates raised rims and rampartlike features such as those seen by NASA’s Cassini spacecraft around the moon’s Winnipeg Lacus. New research using Cassini radar data and modeling proposes that lake basins like these are likely explosion craters, which could have formed when liquid molecular nitrogen deposits within the crust warmed and quickly turned to vapor, blowing holes in the moon’s crust. This would have happened during a warming event (or events) that occurred in a colder, nitrogen-dominated period in Titan’s past. The study may provide evidence of these cold periods in Titan’s past, followed by a relative warming to conditions like those of today. Although Titan is frigid compared to Earth, methane in the atmosphere provides a greenhouse effect that warms the moon’s surface. Image credit: NASA / JPL-Caltech.

This Hubble image reveals an ancient, glimmering ball of stars called NGC 1466. It is a globular cluster that is slowly moving through space on the outskirts of the Large Magellanic Cloud. NGC 1466 has a mass equivalent to roughly 140,000 Suns and an age of around 13.1 billion years, making it almost as old as the Universe itself. Image credit: NASA / ESA / Hubble.
