A Stunning Look at Philae

WOW! This is just simply amazing.

This is a two image mosaic of Philae on the surface of the Comet 67P/Churyumov-Gerasimenko. Click the image and just marvel at the view of both Philae and the surface features.

You can get an even larger version at Rosetta blog’s Welcome to a Comet!

Philae is pretty close to a cliff that will shadow the solar panels for much of a day and this will limit how much Philae will be able to do at least in the short term. I’m pretty sure ESA is studying how to squeeze the most out of what they have you can be sure of that.
ESA is live streaming the media briefings, you can find out when by going to Rosetta Blog or you can check the Live Stream page.

Don’t forget about Twitter, I am on the run a lot the past couple days and it has been great for keeping up you can get all the images and briefings there too.

Good Luck Philae!

GOOD LUCK!  I can hardly believe the day has finally come – it’s been a long time!

Update:  Landing confirmed.  Harpoons did not fire, investigation in progress.  The one way radio travel time is a bit over 28 minutes – each way.

ESA is reporting all is well with Philae is in good shape despite the harpoons.

If you see no video above it is because ESA isn’t broadcasting at the time.

Check out the Rosetta Blog and for last second updates.

The big day is almost here. What will happen once Philae lands on Comet 67P/Churyumov–Gerasimenko?

This from ESA:

A timeline of the science operations that Rosetta’s lander Philae will perform during the first 2.5 days on the surface of Comet 67P/Churyumov–Gerasimenko.

It does not include the experiments conducted during the seven-hour descent or immediately upon touchdown and in the 40 minutes after as the separation, descent and landing operations and experiments conclude (see this graphic for a summary of those activities).

Ambition – The Film

About the video from ESA (YouTube)

Ambition is a collaboration between Platige Image and ESA. Directed by Tomek Bagiński and starring Aiden Gillen and Aisling Franciosi, Ambition was shot on location in Iceland, and screened on 24 October 2014 during the British Film Institute’s celebration of Sci-Fi: Days of Fear and Wonder, at the Southbank, London.

DDO 68 An Odd Little Galaxy

From the ESA’s Hubble page:

Astronomers have studied galactic evolution for decades, gradually improving our knowledge of how galaxies have changed over cosmic history. The NASA/ESA Hubble Space Telescope has played a big part in this, allowing astronomers to see further into the distance, and hence further back in time, than any telescope before it – capturing light that has taken billions of years to reach us.

Looking further into the very distant past to observe younger and younger galaxies is very valuable, but it is not without its problems for astronomers. All newly-born galaxies lie very far away from us and appear very small and faint in the images. On the contrary, all the galaxies near to us appear to be old ones.

DDO 68, captured here by the NASA/ESA Hubble Space Telescope, was one of the best candidates so far discovered for a newly-formed galaxy in our cosmic neighbourhood. The galaxy lies around 39 million light-years away from us; although this distance may seem huge, it is in fact roughly 50 times closer than the usual distances to such galaxies, which are on the order of several billions of light years.

Read the rest at ESA’s Hubble page.

A side note: I thought this dwarf galaxy was actually two galaxies in the process of merging, apparently not?
