Visible and Infrared Views of Comet Tempel 1 (Artist's Concept): These artist's concepts of Tempel 1 simulate an optical view of the comet (left), next to the simulated infrared view (right). The images illustrate the comet's shape, reflectivity, rotation rate and surface temperature, based on information from NASA/ESA Hubble Space Telescope and Spitzer Space Telescope. Measurements from the Great Observatories indicate that the comet is a matte black object roughly 14 by 4 kilometers (8.7 by 2.5 miles), or about one-half the size of Manhattan. Spitzer detects the comet's infrared energy or heat, depicted by the reddish glow. The sunlit side of the nucleus is glowing warmly, and the nightside is about the temperature of deep space.

An artist's view of the Pluto system: This illustration shows the Pluto system from the surface of one of the candidate moons. The other members of the Pluto system are just above the putative moon's surface. Pluto is the large disk at center, right. Charon, the system's only confirmed moon, is the smaller disk to the right of Pluto. The other candidate moon is the bright dot on Pluto's far left.

Pluto's Moon May Have Company (artist's impression): Hubble reveals two previously undetected satellites likely orbiting Pluto in the same plane as Pluto's moon, Charon. The two objects are estimated to have diameters between 40 and 125 miles (64 and 200 kilometers) and orbit roughly 27,000 miles (43,000 kilometers) from Pluto.

Hubble Spies a Zoo of Galaxies: Gazing deep into the universe, NASA/ESA Hubble Space Telescope has spied a menagerie of galaxies. Located within the same tiny region of space, these numerous galaxies display an assortment of unique characteristics. Some are big; some are small. A few are relatively nearby, but most are far away. Hundreds of these faint galaxies have never been seen before until their light was captured by Hubble.

Section of M51 with progenitor star: This ESO/NASA Hubble Space Telescope picture shows M 51, an interacting spiral galaxy, which is also known as the Whirlpool Galaxy. It is located about 25 Million light years away from Earth, but can still easily observed with a small telescope by amateur astronomers. M 51 is also a popular object among professional astronomers as it shows an ongoing enhanced star formation rate, which is probably caused by the interaction with its companion galaxy (not visible on the picture). The galaxy was also the location of two supernovae within the last couple of years: The first one appeared in 2005, the second one in 2011.

Hubble catches scattered light from the Boomerang Nebula: The NASA/ESA Hubble Space Telescope caught the Boomerang Nebula in images taken with the Advanced Camera for Surveys in early 2005. This reflecting cloud of dust and gas has two nearly symmetric lobes of matter that are being ejected from a central star. Each lobe of the nebula is nearly one light-year in length, making the total length of the nebula half as long as the distance from our Sun to our nearest neighbors - the alpha Centauri stellar system, located roughly 4 light-years away. The Boomerang Nebula resides 5,000 light-years from Earth. Hubble's sharp view is able to resolve patterns and ripples in the nebula very close to the central star that are not visible from the ground.

Hubble view of Aristarchus plateau on the Moon: The Hubble Space Telescope Advanced Camera for Surveys imaged Aristarchus crater and nearby Schroter's Valley rille on Aug. 21, 2005. The Hubble images reveal fine-scale details of the crater's interior and exterior in ultraviolet and visible wavelengths at a scale of approximately 50 to 100 metres per picture element.

Aristarchus Crater in False Color: This colour composite focuses on the 42-kilometer-diameter Aristarchus impact crater, and employs ultraviolet- to visible-color-ratio information to accentuate differences that are potentially diagnostic of ilmenite- (i.e, titanium oxide) bearing materials as well as pyroclastic glasses. The symphony of colour within the Aristarchus crater clearly shows a diversity of materials - anorthosite, basalt, and olivine. The images were acquired Aug. 21, 2005. The processing was accomplished by the Hubble Space Telescope Lunar Exploration Team at NASA's Goddard Space Flight Center, Northwestern University, and the Space Telescope Science Institute. False-color images were constructed using the red channel as 502/250 nanometers; the green as 502 nanometers; and the blue as 250/658 nanometers. North is at the top in the image.

A Close-Up View of the Aristarchus Crater: The Hubble Space Telescope's Advanced Camera for Surveys snapped this close-up view of the Aristarchus crater on Aug. 21, 2005. The crater is 26 miles (42 kilometers) in diameter and approximately 2 miles (3.2 kilometers) in depth, and sits at the southeastern edge of the Aristarchus Plateau. Aristarchus is one of the youngest and largest craters on the Moon. The crater formed between 100 and 900 million years ago.
