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…
Research Astronomer Dr Apostolos Christou reports on a new model to explain the two “oddball’’ moons of Neptune: Triton, a >2000 km diameter satellite that circles Neptune in the opposite direction that the planet rotates; and 300-km Nereid, the planetary moon with the most elongated orbit in the solar system.

Breaking astronomy news! The European Southern Observatory, in combination with other institutes, has discovered a black hole – and it’s a mere 1000 lightyears from Earth! This newly discovered Black Hole forms part of a triple system (called HR6819) that can be seen with the naked eye. Petr Hadrava, Emeritus Read more…
Armagh Observatory reports that April 2020 was much sunnier than average at Armagh, much warmer and much drier. This was the sunniest April at Armagh for 118 years, the second-sunniest April at Armagh since sunshine records began in 1880, and the equal fourth-warmest on record. Total precipitation was 16.6 mm Read more…
Martina Glass looks at the morning sky and what treats it has for us! For thousands of years people used the stars to tell stories, mark the changes in seasons and to help navigate, but even with today’s technological advances many people now know less than those early cultures did. Read more…
The transition region in the Sun is the atmospheric layer that separates the cooler chromosphere from the hotter corona. Studying the structure and dynamics of the transition region requires greater attention as these provide critical information on the supply of mass and energy from the lower atmosphere to the corona and Read more…
By Christopher Duffy Studies of the sun, our closest star, have shown that sun spot activity and solar eruptions, also known as solar flares, are strongly correlated – regions of the sun with many sun spots are found to be the typical point of origin for most solar flares. This Read more…
