Article written by: Ciara, from Ciara’s Journey Blog It’s an umbrella term for Comets, Asteroids, Meteoroids, Meteors, Meteorites and Bolides. It’s anything that is in our Solar System and that isn’t a planet or a satellite! In this blog post I have explored what each of these things are – Read more…
Lying somewhere between young main-sequence stars and old white dwarfs, hot subdwarfs are blue stars with about half the mass, a tenth the diameter and ten times the brightness of the Sun.
The 2019 Nobel prize for physics has been awarded to three scientists: James Peebles, Michel Mayor and Didier Queloz. This blog post will briefly outline why Mayor and Queloz were awarded their prize. In 1995 these Swiss astronomers announced the discovery of the first planet orbiting another ‘solar type’ star.

Following from last week’s introduction to our climate change series, this week we have an article explaining how climate change actually works and why it happens. Firstly, we will be drawing on our sister planet Venus as an example. Earth’s Evil Twin Earth and Venus are, on the face of Read more…
Measuring Gravity As part of a survey to determine the true topography of Ireland by Ordnance Survey Ireland, AOP has recently hosted an experiment designed to measure the Earth’s gravity to an incredible precision, just 10 nms-2! That’s an incredible 0.00000001 ms-2! To put into context just how accurate that Read more…
When the first module of the International Space Station (ISS) launched from Kazakhstan in 1998, humans just had a small orbiting home, about the size of a bus. Over the past two decades it has expanded beyond recognition, and is now an orbiting science laboratory that is literally out of Read more…
We don’t like to think about it, but the world will end one day. It is likely to be engulfed by the Sun as it expands into a red giant star 6 billion years from now, but whether humans survive to see that day is up for debate (climate change…). With regards to the universe, Read more…
Continuing our weekly Astronomy & You series we have an article explaining the invention of Wi-Fi from Tony Beasley. Tony is an IAU member and is President of Commission B4 Radio Astronomy within the organisation. Tony is also the Director of The National Radio Astronomy Observatory in the USA. The history Read more…
Summer’s here! The weather’s heating up and skies will hopefully be clear for a bit of stargazing! There are lots of interesting sights in the sky this July, so while you may have to wait longer for it to get dark, get outside, allow your eyes to adjust and get Read more…
This week our Astronomy & You series takes a look at Electronic Imaging Detectors and their effect on our lives. This piece was written by Ana I. Gomez de Castro. Ana is a full professor in Astronomy and Astrophysics and member of the Mathematics Faculty in the Universidad Complutense de Madrid Read more…
