The latest image of comet 67P/Churyumov-Gerasimenko. When this picture was taken on July 29th, Rosetta was 1950 km from the comet, and each pixel in the image corresponds to about 37 m. Geographic features on the comet are becoming more apparent.

Future Missions For Venus

Venus is considered to be Earth’s sister planet. They are of similar size and have a similar composition. But Venus is not studied as much as the other planets. In order to learn more about our neighboring planet, NASA started the Venus Exploration Analysis Group (VEXAG). Their purpose is to identify scientific and mission goals for Venus.

In the reports released by VEXAG, some scientific goals listed include understanding the formation and evolution of Venus’ atmosphere, determine the surface and interior structure, and learn whether liquid water ever existed on the planet.

In addition to scientific goals, the reports also identify potential missions. These would include an orbiter with radar imaging capabilities to study the atmosphere and a short-duration lander to study the local geology.

The reports can be found on the VEXAG website.

Planck’s New Dust Model
Title: Planck 2013 results. XI. All-sky model of thermal dust emission
Authors: The Planck Collaboration
Planck’s latest all-sky survey presents a model of the thermal dust emission. This new model provides an estimate of the temperature of dust throughout the sky and an improved estimate of the dust opacity.
The technical paper has a lot of interesting analyses and can be found here.
Image: A map of the dust optical depth. The Galactic center is towards the center of the map.

Physicists at the Large Hadron Collider have just detected a subatomic process even more elusive than the mass-endowing Higgs itself: a scattering of two same-charged particles called W bosons off one another. It may not sound quite as exciting as the decades-long hunt for the Higgs and its Nobel-winning discovery, but it’s a testament to the absurd precision possible at the LHC. 
So how rare is this scattering? Just imagine pulling a needle out of 100 trillion pieces of exploding hay. 
And why sift through all that data? It’s a crucial test of the Standard Model that describes the quantum world in glorious and elegant detail. Also, it may lead us into uncharted territory:
From the story:

“The Standard Model has so far survived all tests, but we know that it is incomplete because there are observations of dark matter, dark energy, and the antimatter/matter asymmetry in the universe that can’t be explained by the Standard Model,” Pleier said. So physicists are always looking for new ways to test the theory, to find where and how it might break down.

A few days ago, we found out that comet 67P/Churyumov–Gerasimenko is a contact binary. Now we have a rotating view of it. This gif uses 36 images each separated by 20 minutes to show a 360° view of the comet. It takes the comet 12.4 hours to complete one rotation.

Rosetta’s Comet is a Contact Binary
A new image of comet 67P/Churymov-Gerasimenko shows that it is actually two smaller objects that have come in contact. The shape of the comet proposes an interesting challenge for the Rosetta spacecraft and its lander, Philae. Later this year, Philae is expected to land on the comet.

This month is the 45th anniversary of the first moon landing and NASA will celebrate with many events to mark the occasion during the next two weeks.
During the event, NASA will share photos and video footage of the moon landing, both on their website and on NASA TV. In addition, NASA TV will broadcast some panel discussions with scientists and astronauts about the future of space exploration and other interesting topics.
There are also two NASA Social events, one in Virginia and one in Florida, for those interested in signing up to attend. The deadline to register is July 15th at 5 PM EDT.
For the whole lineup of events, visit this NASA press release and follow the hashtags #NextGiantLeap and #Apollo45.
