Great Black Spot

The newly upgraded Hubble Space Telescope took this picture of a "bruise" in Jupiter's clouds on July 23. Astronomers believe the dark spot was created when a comet slammed into the giant planet earlier in the month. This is the first picture produced by Hubble's Wide Field Camera 3, which was installed during a spacewalk in May.

Astronaut Tom Marshburn, STS-127 mission specialist, participates in the mission's fifth and final session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the four-hour, 54-minute spacewalk, Marshburn and astronaut Christopher Cassidy (out of frame), mission specialist, secured multi-layer insulation around the Special Purpose Dexterous Manipulator known as Dextre, split out power channels for two space station Control Moment Gyroscopes, installed video cameras on the front and back of the new Japanese Exposed Facility and performed a number of \"get ahead\" tasks, including tying down some cables and installing handrails and a portable foot restraint to aid future spacewalkers.

Orbital chores

Endeavour astronaut Tom Marshburn works on a platform attached to the international space station during a July 27 spacewalk. The shuttle Endeavour's crew installed the final piece of Japan's orbital lab during their 16-day mission.

Informally known as the \"Soap Bubble Nebula\", this planetary nebula (officially known as PN G75.5.7) was discovered by amateur astronomer Dave Jurasevich on July 6th, 2008. It was noted and reported by Keith Quattrocchi and Mel Helm on July 17th, 2008. This image was obtained with the Kitt Peak Mayall 4-meter telescope on June 19th, 2009 in the H-alpha (orange) and [OIII] (blue) narrowband filters. In this image, north is to the left and east is down.

PN G75.5.7 is located in the constellation of Cygnus, not far from the Crescent Nebula (NGC 6888). It is embedded in a diffuse nebula which, in conjunction with its faintness, is the reason it was not discovered until recently. The spherical symmetry of the shell is remarkable, making it very similar to Abell 39.

Stephan's Quintet--A Galaxy Collision in Action
Stephan's Quintet, a compact group of galaxies discovered about 130 years ago and located about 280 million light years from Earth, provides a rare opportunity to observe a galaxy group in the process of evolving from an X-ray faint system dominated by spiral galaxies to a more developed system dominated by elliptical galaxies and bright X-ray emission. Being able to witness the dramatic effect of collisions in causing this evolution is important for increasing our understanding of the origins of the hot, X-ray bright halos of gas in groups of galaxies.

Beautiful Quintet

Stephan's Quintet is a compact group of galaxies discovered about 130 years ago and located about 280 million light-years from Earth. This photo, released July 9, combines imagery in visible light (from the Canada-France-Hawaii Telescope) and X-rays (from the Chandra X-Ray Observatory). The bluish ridge in the center of the image represents an X-ray-emitting shock wave that has been generated by the crash of galaxies.

After a Crabwalk Test

Mars Exploration Rover team members prepare a testing setup for a subsequent experiment after an experiment driving the rover in a crablike motion, with all four corner wheels angled to the right. Clockwise from top: Scott Maxwell, Pauline Hwang, Kim Lichtenberg. 

This work on July 9, 2009, was part of a series of tests at NASA's Jet Propulsion Laboratory, Pasadena, Calif., designed to determine the best way to get NASA's Spirit rover out of a Martian patch of soft soil called \"Troy,\" where Spirit's wheels have dug in. The test setup, in a box that team members are calling the dustbin, simulates the situation at Troy. The box holds about 2.7 tons of a powdery mixture of diatomaceous earth and fire clay. This material has physical properties similar to the soil at Troy. The top surface is sloped at 10 degrees.

How to rescue a Mars rover

Rover team members Scott Maxwell, Pauline Hwang and Kim Lichtenberg prepare a test rover for a July 9 session aimed at figuring out the best way to free it from soft soil in a specially configured "dustbin" at NASA's Jet Propulsion Laboratory. The results of such tests will help engineers devise a strategy for freeing up NASA's Spirit rover, which has been stuck in a similar situation on Mars.

One such mission was the Mars Polar Lander which went permanently silent after entering the Martian atmosphere in December 1999. It is speculated that the landing sequence failed when the legs were deployed and accidentally reported that the lander was on the ground. As a consequence, the parachute was cut while the lander was actually hundreds of feet in the air.

This HiRISE image is one of a sequence searching for either the parachute or the crumpled lander on the ground. However, we expect the debris from this mission to be covered with dust and ice, making it a challenge to identify them. The more eyes that search these images the better, so try your luck!

Most of the surface is covered with patches of small channels. It is thought that these have been carved by vaporized ice. On Mars, the ice goes straight to a gas (a process called \"sublimation\") rather than first melting. So, as the ice heats in the spring and summer, gas is generated and flows under the remaining ice. This flowing gas

Can you spot the Mars lander?

This image of Mars' south polar region is part of a sequence of pictures that were taken by NASA's Mars Reconnaissance Orbiter to look for the Mars Polar Lander or its parachute. The lander was lost after entering the Martian atmosphere in December 1999. Debris from the lander may be covered by dust and ice, making identification difficult. The image was acquired June 3 and released July 8.

Cosmic accelerator

Cosmic rays from our Milky Way galaxy are accelerated efficiently in the remnants of an exploded star, as shown in this June 25 imagery from the European Southern Observatory's Very Large Telescope and NASA's Chandra X-ray Observatory. Researchers studied the color-coded emissions from the supernova remnant RCW 86, which is 8,200 light-years from Earth, to learn how such "super-accelerators" work. They found that the shock wave created by the stellar explosion moves at 1 to 3 percent of the speed of light.
