This week’s instalment of the Technical Applications of Astronomy to Society features a piece written by Professor Antonio Mario Magalhaes; astronomer, IAU member and Full Professor at the Instituto de Astronomia, Geofisica e Ciencias Atmosfericas of the University of São Paulo in Brazil. In this piece, he outlines the wider Read more…
Our view of the cosmos is biased by the vista that is apparent to our eyes. This is what the view in what we call the optically visible portion of the spectrum. To the unaided eye it is a view of a universe full of stars, together with five planets, one Moon and of course the Sun. When augmented with a telescope, our eyes can then see a universe full of galaxies – giant cities of stars.
As an earlier Astronotes article reported on, during its XXX General Assembly in Vienna, held in August 2018, the International Astronomical Union (IAU) put forward a draft resolution to rename the Hubble law as the “Hubble–Lemaître law”. The resolution was proposed to recognise Lemaître’s research on the expansion of the Universe, and to pay tribute to both Lemaître and Hubble for their fundamental contributions to the development of modern cosmology.
October is here! It is one of our favourite months as there is so much more to see in the sky and the nights are getting deliciously darker. One thing to remember when you are stargazing is to wrap up warm when you venture outside. The nights are getting much colder, and with some of the best stargazing occurring in the early hours of the morning, we don’t want anyone catching a chill. Thermals and a thermos filled with hot chocolate or coffee will do the trick. Also don’t forget that we will be starting our Star Tracker evenings in the coming months!
After a special vote in the IAu General Assembly, we interview Armagh Observatory and Planetarium Director. Professor MIchael Burton, on the renaming of the Hubble Law.
The Observatory and Planetarium has welcomed school students to visit for work experience. A previous Astronote described our work with the Faulkes Telescope Project. Below is an account written by three of our work experience students in 2018 March, based on the work done at Armagh Observatory and Planetarium by them and three other students.
