Rosetta is getting close and Comet 67P/Churyumov-Gerasimenko looks to be a very good choice. The since the previous image release on 4 July, Rosetta as reduced its distance to the comet by 25,000 km (to 12,000 km from 35,000 km).

Description from ESA:
Comet 67P/Churyumov-Gerasimenko was imaged on 14 July 2014 by OSIRIS, Rosetta’s scientific imaging system, from a distance of approximately 12 000 km. This image has been processed using ‘sub-sampling by interpolation’, a technique that removes the pixelisation and makes a smoother image. It does not, however, reveal hidden detail and it is therefore important to note that the comet’s surface is not very likely to be as smooth as the processing implies. The image suggests that the comet may consist of two parts: one segment seems to be rather elongated, while the other appears more bulbous.

If you venture over to the ESA site you can see a Hi-res version of this beauty.
This view, captured by the NASA/ESA Hubble Space Telescope, shows a nearby spiral galaxy known as NGC 1433. At about 32 million light-years from Earth, it is a type of very active galaxy known as a Seyfert galaxy — a classification that accounts for 10% of all galaxies. They have very bright, luminous centres comparable to that of our galaxy, the Milky Way.
Here is a bit more data on NGC 1433 including a “more normal” image to compare this incredible Hubble image too.
20 years? Already? Hard to believe but true.
Comet Shoemaker-Levy 9 impacted the planet Jupiter 16 July 1994. The comet broke up under the influence of the gravitational pull of the planet during a close pass in July 1992 (was within the Roche limit) and impacted two years later.
The image above is one of many images you can find at our Comet Shoemaker-Levy 9 page. Be sure to visit the links for the legendary Eugene Shoemaker too.

Two launches in two days!.
It is pretty hard to do a launch video much better than SpaceX, here’s the look of the Space X Launch.
The Falcon 9 Rocket left the SpaceX Launch complex 40 at Cape Canaveral in Florida. The payload is SIX ORBCOMM OG2 satellites.
The launch went off without a hitch at 11:15 EDT 15:15 UTC.
Check out the stills at the SpaceX site.
Antares rocket and a supermoon on Saturday. Image Credit: NASA/Aubrey Gemignani
Nice picture from NASA of the Super Moon setting over the Orbital Science Antares rocket with the Cygnus cargo ship ready for flight. See the original here (suitable for a nice desktop).
The Antares did launch successfully today. Nice launch too, although I admit to doing the same thing as the last launch: as the Antares first leaves the pad, I’m saying ” come on, come on – get up there you can do it”. There is a (short) time where it looks like the rocket is just able to lift itself, a short time, yes but long enough to get me wondering! Here’s a replay if you missed it. So far everything looks great with Cygnus.
Now hopefully you got a look at the nice full moon we had. It was really quite spectacular. This full moon was just one of three in a row. Yes! August and September will also have the perigee “Supermoons”.
Here is a NASA ScienceCast video explaining the Supermoons.
Part of the story from the YouTube site:
Between 1838 and 1845, Eta Carinae underwent a period of unusual variability during which it briefly outshone Canopus, normally the second-brightest star. As a part of this event, which astronomers call the Great Eruption, a gaseous shell containing at least 10 and perhaps as much as 40 times the sun’s mass was shot into space. This material forms a twin-lobed dust-filled cloud known as the Homunculus Nebula, which is now about a light-year long and continues to expand at more than 1.3 million mph (2.1 million km/h).
Reminder: Cygnus is ready to launch at 16:52 UTC (12:52 EDT). Check this post to see if you can see the Cygnus and Antares rocket as it goes into orbit.
If you live along the US east coast you may get a look at the Antares rocket as shown in the map. Image: NASA / Orbital Sciences
Mission/Orbiter:Orbital Sciences Orbital-2 Cargo resupply / Cygnus spacecraft
Mission Highlights: This mission will deliver more than 1,360 kg (3000 lbs) of assorted supplies, hardware and tools. A group of nanosatellites are part of the scientific payloads. The nanosats will capture imagery of Earth, will aid in development of a way to return small samples from the ISS and student-designed experiments.
Current Status: Go
Launch Date UPDATED: Sunday 13 July 2014 16:52 UTC (12:52 EDT)
Launch Facility:Wallops Flight Facility (Virginia)
Here’s an animated version of images released by ESA, hopefully you get some sense of 67P/Churyumov-Gerasimenko’s rotation.

Comet 67P/Churyumov-Gerasimenko, taken by the narrow angle camera of Rosetta’s scientific imaging system, OSIRIS, on 4 July 2014, at a distance of 37 000 km. The three images are separated by 4 hours, and are shown in order from left to right. The comet has a rotation period of about 12.4 hours. It covers an area of about 30 pixels, and although individual features are not yet resolved, the image is beginning to reveal the comet’s irregular shape.
A color image of Europa. Click for larger. Image Credit: NASA/JPL-Caltech/SETI Institute
NASA gives us this newly released image of Europa created from images taken by the Galileo spacecraft in 1997 and 1998.
Click the image to get a good look at the amazing terrain!
The following caption from JPL/NASA:
This colorized image of Europa is a product of clear-filter grayscale data from one orbit of NASA’s Galileo spacecraft, combined with lower-resolution color data taken on a different orbit. The blue-white terrains indicate relatively pure water ice, whereas the reddish areas contain water ice mixed with hydrated salts, potentially magnesium sulfate or sulfuric acid. The reddish material is associated with the broad band in the center of the image, as well as some of the narrower bands, ridges, and disrupted chaos-type features. It is possible that these surface features may have communicated with a global subsurface ocean layer during or after their formation.
