Pythagorean Astronomy: Space Environmentalism

Posted on 30 May 2022 by Chris North

In the 65 years since Sputnik 1 was launched in 1957, the number of artificial satellites in orbit has been increasing. In the last two years, the number of satellites has doubled, largely thanks to the huge “constellations” launched by companies such as SpaceX. The number of satellites has a detrimental impact on astronomical observations,

Pythagorean Astronomy: Black holes – too big and too small

Posted on 3 September 2020 by Chris North

If there’s anything that pricks up the ears in astronomy, it’s black holes. And this month we have not one, but two black hole stories. And, depending on how you count them, four black holes, though two of them no longer exist – if that sounds confusing, then don’t worry, it’ll become clear! Regular listeners

Pythagorean Astronomy: out with the old, in with the new

Posted on 27 February 2020 by Chris North

Betelgeuse is still misbehaving, though we’re starting to get more information in from new observations by some of the largest telescope. Astronomers are narrowing in on the possible explanations. Chris, Edward and Claudia discuss what the implications might be. While the dimming of Betelgeuse isn’t anything to do with aliens, the SETI programme is still

Pythagorean Astronomy: interstellar comets, black holes and gravitational waves

Posted on 31 October 2019 by Chris North

October 2019 saw the first all-female spacewalk, and the discover of 20 new moons of Saturn. There were also more observations of interstellar comet Borisov, and evidence for the Milky Way’s black hole having sent out a violent flare several million years ago. Chris North and Edward Gomez discuss these latest stories. October also saw

Pythagroean Astronomy: Lunar Gateways, Belching Black Holes and Warped Galaxies

Posted on 4 September 2019 by Chris North

The summer might be “silly season” in the press, but not so in astronomy. With peroxide on moons and belching black holes there’s lots of sensible research going on for us to discuss. A number of recent rocket engine tests lead us to consider what the near future of space travel might look like, with

Pythagorean Astronomy: Engine Failures to Event Horizons

Posted on 30 April 2019 by Chris North

A roundup of the month’s news from around the Solar System – and beyond. Starting with the Moon, where the first attempt by a privately funded organisation to land on the Moon has ended in a crash-landing. Despite the sad end, the Beresheet mission was otherwise a success, and a promising start for privately funded

Pythagorean Astronomy: Gravitational Waves and Life from Venus?

Posted on 1 July 2017 by Chris North

At the start of June the LIGO team announced that they had made the third firm detection of gravitational waves from the merger of two black holes. This latest detection, from the second observing run, adds to the collection of massive binary black holes detected by LIGO. One of the things that can be determined
