Pythagorean Astronomy: Gravity and Light

Posted on 25 October 2017 by Chris North

On 16th October a huge team of astronomers announced to the world that they had detected, for the first time, gravitational waves and light from the same event. That event was the collision of two neutron stars in a galaxy around 130 million light year away. The signal was first detected by the LIGO and

Pythagorean Astronomy: Cassini’s Grand Finale

Posted on 3 October 2017 by Chris North

The 15th of September marked the Cassini spacecraft’s final plunge into Saturn’s gaseous atmosphere. This grand finale marked then end of a 20 year journey, 13 of which were spent orbiting Saturn, studying the ringed planet and its extended family of moons. Here in Cardiff, Dr Emily Drabek-Maunder has been closely following Cassini, and working

Pythagorean Astronomy: Cassini’s Grand Finale

Posted on 31 May 2017 by Chris North

This month we don’t just look back at a few news stories, but also ahead to what’s happening over the coming months for one of the most successful space missions ever: Cassini. Having orbited Saturn for 13 years, Cassini’s fuel is running out and the mission has embarked on a “Grand Finale” before its final

Pythagorean-Astronomy: ExoMars and Galaxies

Posted on 27 October 2016 by Chris North

A lot has happened this month – ESA got a spacecraft into orbit around Mars, but sadly lost the Schiaparelli lander, China launched two new taikonauts to their space station, and the Swarm mission uncovered details from Earth depths. Edward Gomez and I discussed these, and more, this month (though before the full nature of

Pythagorean Astronomy: Rosetta & OSIRIS-Rex

Posted on 26 September 2016 by Chris North

This month sees the start of one mission and the end of another. NASA’s OSIRIS-REx mission launched at the start of the month to go and study asteroid Bennu, and even bring back a sample to Earth. Meanwhile, the end of the month sees the finale of ESA’s Rosetta mission, which has spent two years studying comet 67P/Churyumov-Gerasimenko. With

Pythagorean Astronomy: Proxima b

Posted on 26 August 2016 by Chris North

After a few weeks of rumours, the announcement of the discovery of an Earth-size (maybe!) planet around the Sun’s nearest neighbour has caused quite a stir. The planet is more massive than the Earth, but probably not by much, and sits in a location where liquid water could (at least in principle), exist on it’s

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
