HFI is off 

Planck, the satellite for which I've worked since around 1996 was turned off today. Here is the message from Laurent Vibert, the operations manager:

I should make it clear that this was totally expected: Planck actually lasted twice as long as required. We posed next to the last bits of data coming in. You can see the noise in the top two plots "flatline" towards the right of each panel...

Apropos of nothing 

As I noted in the previous post, Planck has made it into a number of newspapers recently. The one I like most, and which is the first one I saw, was a cartoon from Le Monde:

(if this doesn't show up, you can also find it here). It says, basically "Here's an image of the Universe just after the Big Bang"; "An ultra-flat disk that then expands. Cool, no?"; "We come from a pizza?".

I'm pretty sure this is about Planck, and that it refers to this Planck image of the Universe:

(which I have to admit does look something like a pizza. We call it the Pink Panther, and I'm glad our newer images look different. But I digress).

But I'm really not sure, because the cartoon was on a page with a bunch of stuff that had nothing to do with Planck. It was, well, the daily news. Which I suppose is appropriate, but do the editors of Le Monde actually expect people to get the allusion? Do they? If so, the French are FAR better informed that I am, in general...

And this is not an isolated occurrence. I was in France when the BOOMERANG results came out, and I found (or rather, Eric Hivon found) this in Le Canard Enchaine:

It says "The Universe is not shaped like a saddle."; "Which at least proves that God is not a knight."

Again, this was just surrounded by a bunch of other... news. Nothing else about BOOMERANG or cosmology, or anything else.

Seems like newspapers here in France have a lot of confidence in their readers. Or don't care...

The Big Release 

So, you may have heard that we've finally released our first cosmology results. I'm pleased and surprised with the coverage:

Cluster Connection 

We just made a "web release" describing a Planck paper that just came out describing measurements of clusters of galaxies close to each other:
