Two Amazing Images of Comet 67P/CG

A new imager turning out some impressive work on the Rosetta mission has popped up on flickr. These are not only gorgeous, but are the first color images I have seen of the comet thus far. Check out 2di7 & titanio44’s image feed and see not only more color images of the comet Churyumov-Gerasimenko, but also great work done at Mars and Saturn as well.

Image Notes: The original of the first image above can be seen here. What is posted here was cleaned up a bit by wanderingspace.net and is not intended for scientific use. We did the best to represent what is in the original, but telling the difference between what might have been boulders and what was image noise is hard to determine. Also, the jets were reprocessed and altered to appear smooth in this final version. More on the color below.

Image Notes: According to the imagers, there have been no filtered images released as of this date of Comet 67P/CG. Which means that the color above is artistic interpretation. Strikingly real looking, but still just a make-shift approach to consider what the color might be before any real data on color has been released by ESA.

Rosetta Selfie

With the term “selfie” trending the way it is in popular culture… it was wise for the people at ESA to try a robotic interplanetary version. This image was shot by the Philae lander (still attached to Rosetta) staring down one of Rosetta’s solar panels looking at comet 67P/C-G in not-too-far-off distance.

Worth noting this similarly happened here at Mars in 2007.

Discover’s Best of Amateur Imagers

Discover online has an article today about some of the best in amateur space imaging. Many of which have been featured here on Wanderingspace before like Gordan Ugarkovic, Emily Lakdawalla and Bjorn Jonsson to name a few. The last item from Bill Dunford of Riding With Robots is an image that he actually suggested NASA point their HiRise cameras at that location. He suspected they might find something interesting there and they did —flash water movement and evidence of avalanches.

When It’s a Jet, It’s a Jet All the Way

Comet Churyumov-Gerasimenko (aka CG-67P) is showing the early formation of it’s jets. Those jets are what cause the formation of the most distinguishing characteristic of any comet — it’s tail. The Rosetta spacecraft is currently in orbit about the comet and it is assumed that as the pair orbit closer to the sun, these jets will become much more active and should provide quite a show for us. The Rosetta team has also recently shared the potential landing sites for it’s Philae Lander in November shown here.

Surface of Venus Revealed Again

One of the best images to ever grace this blog has to be Don P. Mitchell’s re-renderings of Venera 13 and 14. A miraculous re-rendering of Soviet-era data to create a whole new “human eyes” look at the surface of Venus (I also took the liberty of (artistically) colorizing those images as well). Now Ted Stryk — no stranger to these pages — has taken a shot at Venera 9 and 10 as well. The results are not as amazing as Don’s earlier work but that is simply due the missions having a more limited set of data. I must add that it is pleasing to see Ted’s (a scientist) colorizing is similar to our own (not a scientist).

See the whole story of how Ted’s images were made here.

Blacker Than Asphalt

Rosetta has officially arrived at 67P/CG and here is today’s look. These images have apparently been brightened considerably as the comet is supposedly darker than fresh asphalt. It would be good to see what that actually looks like, perhaps something will surface.

Rosetta Nearing Target 67P (That’s a Comet)

This mission is just not getting enough public attention. Launched in 2004, the mission has already flown by Mars and two minor asteroids 2867 Šteins in 2008, and of 21 Lutetia in 2010. However, the real target of the mission is coming this week… a comet with the unforgivable name 67P/Churyumov–Gerasimenko. Rosetta will go into orbit around the comet and observe it for the coming months as it nears the Sun which will cause it to start acting more like a comet and forming the familiar tail. As if that were not enough, a small lander named Philae will attempt to land and attach itself to the comet in November.

Enceladus has 101 Geysers

Apparently there are a whole lot of geysers on Enceladus, more than 100. Well only one more, but there are sure to be others. Most of the geysers spotted so far appear along the four noticeably visible “tiger stripes” that appear in the southern hemisphere.

These are two of the most recent images to come from Cassini on this hot region of this medium sized moon. Nice seeing the detail on the geysers in the dark regions of the images where you can actually see where they are originating from on the surface.

Happy Revolution Around the Sun Card

As a fan of space exploration, you will have to love this birthday card from Chop Shop. An overly technical acknowledgment of someone’s birthday by defining exactly what it is. One additional complete orbital period moving around the sun. Even better, they design is beautifully letterpress printed both front and inside.

Above reveals the inside text — which plays it a little more safe with the messaging.

Rolf Olsen Photo Renders Neptune

The above is an interesting project to image the full Neptune system based on actual data returned by Voyager. According to the article published along with the image — Rolf Wahl Olsen composed this scene from actual images from the departing Voyager probe. The rings (which were never photographed in their entirety) are based on over-exposed images and then density mapped to a model which was applied to the scene. Even the stars are based on one of the over exposed images of the rings which revealed what the probe would have seen and that field data was inserted from and image generated by Google Sky.
