In today's astrobite, we continue our overview of the papers from the Planck 2013 release. This time, we review papers XVII and XXIII, which discuss weak gravitational lensing of the Cosmic Microwave Background, and the isotropy of the Universe at the time this background radiation was emitted.

Just time to post this neat picture I found on the BBC Website this morning: Although these images were obtained using measurements of the cosmic microwave background made by Planck, they are not themselves maps of the radiation field itself. As photons produced in the early Universe travel through the Universe towards the observer, they

Some colleagues have suggested that my posting on Planck Day was overly frivolous, given the huge importance of what Planck has achieved. (Nicely written up by Andrew Jaffe.) Other colleagues have suggested that Planck Day was bad press, as it was such a huge public non-event, with a big fuss about mild parameter adjustment. I

“How could the Universe we see around us be created by an explosion?” This is a question often asked by those puzzled by the scientific consensus, the standard model of...

The primordial seeds of the Universe, the Cosmic Microwave Background, have been measured by the Planck satellite with unprecedented precision. In this post, we summarize some of their results on cosmological parameters and primordial non-gaussianity.

Yesterday's release of the Planck papers and data wasn't just aimed at the scientific community, of course. We wanted to let the rest of the world know about our results. The main press conference was at ESA HQ in Paris, and there was a smaller event here in London run by the UKSA, which I participated in as part of a panel of eight Planck scientists. The reporters tried to keep us honest, asking us to keep simplifying our explanations so that they — and their readers — could underst

If you're the kind of person who reads this blog, then you won't have missed yesterday's announcement of the first Planck cosmology results. The most important is our picture of the cosmic microwave background itself:But it takes a lot of work to go from the data coming off the Planck satellite to this picture. First, we have to make nine different maps, one at each of the frequencies in which Planck observes, from 30 GHz (with a wavelength of 1 cm) up to 850 GHz (0. 350 mm) — note that the

Behind every modern tale of cosmological discovery is the supercomputer that made it possible. Such was the case with the announcement yesterday from the European Space Agencies' PlanckÂmission team which raised the age estimate for the universe to 13. 82 billion years and tweaked the parameters for the amounts dark matter, dark energy and plain old

... was asked to go on the BBC5Live Drive show yesterday to talk about cosmology (the Planck results). You can listen here for the next six days (2:40:55-2:44:55). Or this lower quality clip will last forever (on SoundCloud).

(Immagine, credit ESA and the Planck Collaboration)NEWS SPAZIO :- Ritorniamo a parlare della missione del telescopio spaziale Europeo Planck, lanciato nel Maggio 2009 ed in orbita intorno al punto Lagrangiano L2 dal Luglio 2009. La sua missione principale studiare le origini dell'Universo. La spettacolare notizia che ieri 21 Marzo stata pubblicata la mappa della Radiazione Cosmica di Fondo (Cosmic Microwave Background Radiation o CMBR) ottenuta con i dati di Planck, la più dettaglia

Like archaeologists sifting through the dust of ancient civilizations, scientists with the ESA Planck mission today showed a map of the oldest light in the Universe. The first cosmology results of the mission suggest our Universe is slightly older and expanding more slowly than previously thought. Planck's new estimate for the age of the Universe

The reason I was out of the office yesterday was that I was in Cambridge, doing a PhD oral in the Cavendish Laboratory so the first thing to say is congratulations Dr Johnston! It was one of those viva voceÂexaminations that turned out to be less of an examination than an interesting chat about physics.

Been watching the ESA Planck live press junket George show thingy. Well, everybody and his hairdresser will be writing up their well considered Planck thoughts over the next hour and a half, so I thought I would just summarise some personal lessons. The follow-on press release is here. Apparently there will be more serious stuff

... big day for science today, as at last we'll find out some of the first cosmology results from the Planck telescope. Planck was launched together with the Herschel Space Telescope back in 2009, to perform an all-sky survey at microwave wavelengths. The survey will produce – or rather, has now produced – the most

Greg Dobler (UCSB) gave the astro seminar today, on the WMAP, Fermi, and now Planck haze at the center of the Milky Way. My take-away is that, energetically, it is not hard to explain, but specifically it has morphological features that are hard to explain. That's like so damned much in astrophysics!Not much other work got done, except I shocked (shocked!) the crowd at stats school by saying that it is almost never the case that you want to select models based on chi-squared per degree of free

My apologies for being far too busy to post. I'll be much louder in couple of weeks once we release the Planck data — on March 21. Until then, I have to shut up and follow the Planck rules. OK, back to editing. (I'll try to update this post with any advance information as it becomes available.) Tags: CMB, Planck
