Stunning close up detail focusing on a smooth region on the ‘base’ of the ‘body’ section of comet 67P/Churyumov-Gerasimenko. The image was taken by Rosetta’s OSIRIS narrow-angle camera and downloaded, 6 August. The image clearly shows a range of features, including boulders, craters and steep cliffs. The image was taken from a distance of 130 km and the image resolution is 2.4 metres per pixel.

There will be some amazing science done in the next 2 years by the team at ESA.

We have had some astronomical disappointments of late but we might just see a really nice meteor shower this Friday night into Saturday morning.
Meteors from the May 24th’s early-morning display can appear anywhere in the sky, but they will appear to originate from a point (called the radiant) in the constellation Camelopardalis, the Giraffe. Stars are plotted for 2 a.m. local daylight time as seen from mid-northern latitudes. Sky & Telescope illustration.
I plan on being up with my Nikon and mosquito spray to hopefully get some nice shots of the unexpected astronomical display. What a nice late spring surprise and who knows, maybe an nice annual event.I will share photos here on Saturday… if all goes well.
These photos were shot in south Baton Rouge on Tuesday morning at 2:45 am. This eclipse marked the beginning of a tetrad, a series of four total lunar eclipses in a row. The next three total eclipses will be occurring on Oct. 8, 2014, April 4, 2015, and the final occurring on Sept. 28, 2015.
The ‘ghosting’ is the rapid movement of the clouds during a 2 second exposure.
Below the moon is Spica, in the constellation Virgo, and Mars is further west(right) in the shots.
I expect to have better photos after the next eclipse… weather permitting. Ha.
“The minuscule ripples in space-time are the last prediction of Albert Einstein’s 1916 general theory of relativity to be verified. Until now, there has only been circumstantial evidence of their existence. The discovery also provides a deep connection between general relativity and quantum mechanics, another central pillar of physics.”(Stuart Clark)

The measurements were taken using the BICEP2 instrument at the South Pole Telescope facility. Now we wait as the scientific community deliberates these findings and maybe, just maybe, we have confirmed more of Einstein’s brilliance.

On March 4, 2014 Charles Bolden, NASA Administrator, released a statement which includes, “In the coming year, we’ll build on our nation’s record of breathtaking and compelling scientific discoveries and achievements in space, with science missions that will reach far into our solar system, reveal unknown aspects of our universe and provide critical knowledge about our home planet. It includes funding for missions to Mars and the formulation for a mission to Jupiter’s moon, Europa.”
It looks as though we may finally go to a ‘local’ body that will hold many surprises and in astronomical distances Europa is so very close.
Europa is just begging us to visit and the Europa Clipper is one mission.
This artist’s impression of Europa makes the place look more exotic than Mars.

After an extensive mapping phase by the orbiter in August–September 2014, a landing site will be selected for Philae to conduct in situ measurements in November 2014. The image is not to scale; the Rosetta spacecraft measures 32 m across including the solar arrays, while the comet nucleus is thought to be about 4 km wide. (Photo: ESA)
Scientists at the European Space Agency (ESA) sounded Rosetta’s internal alarm clock to reboot the mission after two-and-a-half years of deep space slumber. Once its systems warm up, Rosetta is due to beam a signal back to Earth before it begins to home in on a frozen rock known as 67P/Churyumov-Gerasimenko. It is due to shoot harpoons into the 2.5-mile dirtball before its Philae lander docks on the surface – a move that has never been attempted before.
ESA project scientist Matt Taylor likened the mission to that of the action film Armageddon, in which Bruce Willis lands on an asteroid to save the world from destruction. “We’re not just landing on the Moon, we’re dealing with something dynamic, which is kicking off tons of dust and gas every minute,” he told the Sunday Telegraph. Because Rosetta, which has been sleeping to save power, is so far from Earth, it will take 45 minutes for its signal to reach scientists at mission control. They expect to see a blip on computer monitors between 1730 and 1830 GMT, indicating the spacecraft is up and running again.
Dr. Dan Andrews, a planetary scientist at the Open University in Milton Keynes, said: “We’re waiting to hear Rosetta is alive and healthy. “This wake-up call kicks off a chain of events, during which the spacecraft heats itself up, points itself towards the Sun and gets itself ready. “Remember, this mission is 10 years old – it’s a bit of a stroppy teenager and it’s going to take a while to wake up.” If all goes to plan, Rosetta will arrive at Churyumov-Gerasimenko in August before descending to the comet several months later.

Chang’e 3 landed on Mare Imbrium (Sea of Rains) just east of a 450 m diameter impact crater on 14 December 2013. Soon after landing, a small rover named Yutu (or Jade Rabbit in English) was deployed and took its first tentative drive onto the airless regolith. At the time of the landing LRO’s orbit was far from the landing site so images of the landing were not possible. Ten days later on 24 December, LRO approached the landing site, and LROC was able to acquire a series of six LROC Narrow Angle Camera (NAC) image pairs during the next 36 hours (19 orbits). The highest resolution image was possible when LRO was nearly overhead on 25 December 03:52:49 UT (24 December 22:52:49 EST). At this time LRO was at an altitude of ~150 km above the site, and the pixel size was 150 cm.(NASA)

Karl Battams: It may be (almost) gone but comet ISON leaves a legacy of unprecedented data from numerous locations within the solar system! [Image credit: ESA, NASA, Annotations by Karl Battams]
ISON appears as a white smear heading up and away from the sun. ISON was not visible during its closest approach to the sun, so many scientists thought it had disintegrated, but images like this one from the ESA/NASA Solar and Heliospheric Observatory suggest that a small nucleus may be intact.
