Pythagorean Astronomy: The Origins of Black Holes

Posted on 30 June 2016 by Chris North

On 15th June 2016 the LIGO collaboration released more detections of gravitational waves. As with the first detection, announced back in February, these gravitational waves were emitted by pairs of black holes, spiralling together and merging, But of course, those black holes need to come from somewhere, and in this case it’s thought to be the deaths of

Pythagorean Astronomy: New worlds

Posted on 26 May 2016 by Chris North

This month’s focus is on two different stories, but both involving the same spacecraft: Kepler. Edward Gomez and I discuss a result from the outer edge of our Solar System, regarding the icy world that goes by the catchy name of “2007 OR10”. By combining information from the Kepler Spacecraft, now in the second phase

Pythagorean Astronomy: Interplanetary explorers

Posted on 29 April 2016 by Chris North

In this month’s instalment, Edward Gomez and I chat about interplanetary explorers to the icy worlds of Pluto and Ceres, and Cassini’s capture of interstellar dust as it passed through the Saturn system. And, of course, we look ahead to May’s Transit of Mercury, which we’ll be viewing with members of the public and school groups here

Pythagorean Astronomy: to Mars – and Beyond!

Posted on 31 March 2016 by Chris North

March 2016 saw the launch of the first part of Europe’s two-part mission to Mars. The mission, called ExoMars, comprises the “Trace Gas Orbiter” – the part that’s just launched – and a large rover, which launches in 2018. The orbiter will sniff the atmosphere to test for evidence of past  – or maybe even present – life. Elsewhere

Pythagorean Astronomy: the Voice of Einstein

Posted on 25 February 2016 by Chris North

Unless you’ve been under a bush for the past month, you can’t have missed what could be described the news of the Century – the first direct detection of gravitational waves. This month, I speak to Edward Gomez about what this discovery means, and catch up with some of the gravitational physicists here in Cardiff,

Pythagorean Astronomy: 2015 round-up and Tim Peake

Posted on 19 December 2015 by Chris North

It’s been a very exciting year in astronomy and space science, with missions exploring distant reaches of the Solar System. There was a huge media storm about New Horizons passing Pluto back in July, with staggering results still coming back, and continuing revelations from Rosetta. But there was even more excitement about Tim Peake’s launch to the International

Pythagorean Astronomy: Einstein’s Revolution

Posted on 28 November 2015 by Chris North

November 2015 marks the centenary of the publication of one of the most important theories in physics: Albert Einstein’s General Theory of Relativity. On this month’s episode I chatted to Prof Mark Hannam and Dr Patrick Sutton. As part of the Gravitational Physics group here in Cardiff, Mark and Patrick try to understand the implications

Pythagorean Astronomy: Water on Mars – Again!

Posted on 29 October 2015 by Chris North

In October 2015 we had news of the discovery of water on Mars – again! Almost a perennial story now, but is this discovery any different to previous discoveries, some of which stretch back to the 1970s? To find out more about this particular story, I spoke to UCL planetary scientist Peter Grindrod. Originally broadcast

Pythagorean Astronomy: AstroCamp and Galaxies

Posted on 28 September 2015 by Chris North

The arrival of Autumn means one thing to astronomers: darker skies. Every spring an autumn, astronomers gather along with their telescopes, campervans and tents for “star parties”. One such meet-up is AstroCamp, held near Cwmdu in the Brecon Beacons. At just an hour or so north of Cardiff it’s not too far, and I’ve been going along to

Pythagorean Astronomy: In conversation with Mark McCaughrean

Posted on 27 August 2015 by Chris North

On Monday 24th August, Cardiff was treated to a public talk by Prof Mark McCaughrean, Senior Science Advisor in the European Space Agency’s Directorate of Science and Robotic Exploration. Mark spoke about the Rosetta mission, which has been studying comet 67P/Churyumov-Gerasimenko for the past year, including the landing of Philae on the comet’s surface amid huge media attention.
