Chances are, if you’re interested in astronomy, that you’ve heard of William Herschel. A bit of a polymath, he was an accomplished musician, composer and even philosopher, but is best known for his discovery of Uranus, the first planet to be discovered with a telescope (one he’d built himself). Someone you might not be as familiar with, however, Read more…
Written by Dr. Gavin Ramsay One of humankinds greatest achievements was made on 14th Sept 2015 when the first direct detection of a gravitational wave event was made using the aLIGO observatories in Washington State and Louisana in the USA. This event was the result of two Black Holes, each Read more…
NGC stands for the New General Catalogue of Nebulae and Clusters of Stars, which is an astronomical catalogue of deep sky objects and was compiled in 1888 by the 4th director of the Armagh Observatory John Dreyer. To this day the NGC catalogue is still used by Astronomers all over the world and remains one of our many claims to fame! The catalogue contains 7840 objects Read more…
by Apostolos Christou An international team of planetary scientists led by astronomers at AOP have found an asteroid trailing behind Mars with a composition very similar to the Moon’s. The asteroid could be an ancient piece of debris, dating back to the gigantic impacts that formed the Moon and the Read more…
In a new paper, Simon Jeffery reports the discovery of standing waves on two small hot stars similar to the pattern of jet streams seen in the Earth’s atmosphere.
By Gavin Ramsay, AOP Research Astronomer In previous AstroNotes we have highlighted the Gravitational-wave Optical Transient Observer (GOTO) project of which AOP is a partner. Although its main aim is to detect the optical counterparts of cosmic explosions, it has been used to observe some Comets. Last week GOTO observed Read more…
By Simon Jeffery, AOP Research Astronomer In 1930, Dorrit Hoffleit reported that star number #4749 in the Harvard List of variables had faded four times between 1897 and 1929, and identified it as an R Coronae Borealis (RCB) variable. RCB stars are luminous low-mass stars (red giants) with surfaces around Read more…
One of our Astronomers, Dr Gavin Ramsay, reflects on his memories of some of the amazing telescopes he has travelled to throughout his career! When the telescope was invented in early 17th century, they were generally used in the urban environment. Gradually they were housed in quite grand purpose-built buildings Read more…
Have you ever wondered about the impact that you may have as an amateur astronomer? How much can amateur and professional astronomers gain from each other? Can amateur astronomers impact research? Please listen below to a short audio piece by Lucie Affronti and Neasa Cumiskey; two Postgraduate Media students at Read more…
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.
