American Astronomical Society Meeting, Austin

AAS

This week I’m at the meeting of the American Astronomical Society in Austin, TX. I’m excited to be here for a number of reasons, first and foremost that I’ve never been to a AAS meeting before. It’s one of the biggest gatherings of astronomers, so there’s lots of people to meet, including some old friends and colleagues I haven’t seen in a while. And of course there’s the talks, the posters, and the wonderful city of Austin:

I’m planning to organise a meet-up for DotAstronomy alumnae/i and enthusiasts this evening, so keep an eye on twitter for details of that.

As always there’s a big media presence at AAS so expect some astronomy stories in the papers and online this week. AAS have a list of blogs and twitter accounts covering the meeting (mine’s not on there but if I hear interesting talks I’ll certainly write something about it). I’ve had lots of discussions recently about science reporting, peer review, blogging and such, so I was interested to read Blogging & Tweeting guidelines in the printed programme. A few selections:

[...] Please do not publicly report private conversations – only scheduled presentations and public comments are fair game for blogging, tweeting, etc.

Remember that many presentations at AAS meetings concern work that has not yet been peer reviewed. So think twice before posting a blog entry or tweet that is critical of such work. It is helpful to receive constructive criticism during the Q&A after your talk or while standing next to your poster, but it is hurtful to be raked over the coals online before your session is even over and with no easy way to respond. [...]

That’s quite sensible really – it’s not trying to stop people from writing or commenting, just to be balanced, fair and take the status of the work into account. There’s also an embargo policy for the meeting:

When meeting abstracts are available publicly, either electronically or in print, they are not embargoed.Abstracts reflect the situation at the time of submission and often do not correspond exactly to the paper that is ultimately presented, usually months later. Reporters should note that preparing a story based exclusively on an abstract is ill-advised.Some results to be presented at AAS or Division meetings are also the subject of papers whose manuscripts are available via preprint servers such as arXiv.org or that have already been published in scholarly journals. Such publicly available results are not embargoed.Interviews with presenters, as well as graphics, animations, and other information to be presented for the first time at the meeting, are embargoed until the time of presentation, where “time of presentation” means the start time of the oral or poster session in which the paper will be given, or the start time of the corresponding press conference (if any), whichever comes first.For more information, see http://aas.org/press/embargo_policy.

If you’re a blogger/twitter friend, please come say hello!

 

 

.Astro 2012: Haus der Astronomie

Over the summer we announced the venue of the next .Astronomy conference, Heidelberg. This is my current home base, and I’m excited to be at the coalface of the organisational effort once again. It’s a lot of work, but in the end it’s always satisfying to see everything come together.

The main venue will be the brand new Haus der Astronomie, which is currently under construction on MPIA’s picturesque site on the Königstuhl. The Haus’ Director Markus Poessel took this great picture of the building just last week. The work is coming along amazingly well! You can follow the progress of the construction works on the Haus’ facebook page.

 

Open Science @ TEDx Waterloo

One of our keynote speakers at the .Astronomy conference in Leiden in December 2009 was Michael Nielsen, who gave an excellent and inspirational talk on open science. Michael spoke at TEDx Waterloo in March about similar topics, and I thought I’d repost it here. Producing nice slick videos à la TED is perhaps something we should work on for the next .Astronomy!

Modelling comets, kittens and the Universe

Some images returned by the Comet Holmes Yahoo! query (Lang & Hogg, 2011)

 

This post was chosen as an Editor's Selection for ResearchBlogging.orgSome call it the data deluge, others the Fourth Paradigm – whatever your phrase of choice, it’s undeniable that science is increasingly driven by the easy availability of large amounts of data. The web is instrumental in their dissemination around the world. Web service providers such as Amazon enable storage of and access to data in the cloud. Continuing our progress in the exploration of the natural world depends ever more crucially on our ability to curate data and extract information from it.

On the last day of .Astronomy, David Hogg gave a talk on the paper he posted with collaborator Dustin Lang to astro-ph last week. In the paper Lang & Hogg describe how they reconstructed the orbit of Comet 17P/Holmes, which was prominently visible in the night sky in 2007, from images posted to the web by amateur photographers. After performing a Yahoo! image search and sorting out the relevant pictures, they ran their image set through the Astronomy.net system. Astrometry.net, created by Lang, cleverly attempts to calculate an astrometric calibration of astronomical images that contain no positional information, by fitting the positions of stars to known asterisms.

.Astronomy: Here’s One We Made Earlier

Can’t believe .Astronomy is over for another year, but here I am, at Heathrow, on my way home. Our final day yesterday was pretty fun-packed, and apologies to those on twitter who really didn’t need to hear quite so much about kittens or David Hogg. There were some great talks, but I first wanted to list some of the hacks that people presented on Wednesday morning.

I was impressed with what people produced, and .Astro definitely seemed more techy to me than in previous years. We awarded some prizes to hacks we particularly liked in technical and artistic categories – just like in figure skating, cause who doesn’t love figure skating?

In no particular order, here are some links I like. This is by no means a complete list….

Jose Enrique Ruiz recorded a set of pencasts – I’m not sure what the correct verb for this activity is – basically got people to talk about and draw their work with a magicFu pen. It looks super cool.

Amanada Bieberauer put together an arrangement and backing singers for her Pluto song and got Heidelberg’s Markus Poessel to record a music video to go with it. It’s already a bit of a hit I understand, full info and credits on the dedicated site. Markus also produced another .Astronomy trailer, like last time. I loved Boris Häußler‘s video showing exactly how many devices we used to bring down the college wifi network – and ABBA. All the videos are embedded below.

On the tech side, Eli Bressert, Tom Robitaille and Matthew Graham [updated 13/04]produced some code that scrapes Arxiv and displays on one nice page the paper’s title, authors and abstract (like on astro-ph), but also a list of tables and figures for easy downloading. We may never need to read words again. I look forward to seeing this hack up and running.

Our top hacking prize went to Jon Yardley, Haley Gomez, Ed Gomez and Rob Hollow for their ChromoTone project, which lets users explore astronomical images in sound. Top marks for coming up with the chord structure to represent different wavebands and the insertion of the occasional blue note. You can’t go wrong with that.

Pamela Gay, Stuart Lowe, David Hogg and Phil Marshall came up with Astrotaches – an html5-based site that allows users to draw on images as a way of tagging interesting objects. A kind of Galaxy Zoo on speed.

And there were many other fun and useful projects that I hope to hear more about in months to come. And here are the videos…
