This year’s Insight Astronomy Photographer of the Year competition received a record 2700 entries by astrophotographers from 59 countries around the world. These astonishing pictures reveal fresh perspectives on astrophotography favourites alongside some of the great astronomical events of the last year.
We will showcase the winning images from all 11 categories over the next few days, but if you wish to see them all together on display, the Royal Observatory Greenwich has an exhibition open 18 September 2015 — 26 June 2016. Hours: 10.00–17.00, entry is free.
An international research team has used sophisticated computer simulations to calculate a two-dimensional map of the dust chemistry in the solar nebula, the thin dusty disc that surrounded the young Sun and out of which the planets formed. The study has given new insights into the chemical composition of the dust grains that formed in the solar system 4.5 billion years ago.
Some 4 billion years ago, the Sun shone with only about three-quarters the brightness we see today, but its surface roiled with giant eruptions spewing enormous amounts of radiation into space. These powerful solar explosions may have provided the crucial energy needed to create greenhouse gas in Earth’s atmosphere, warming the planet and incubating life.
Our fourteenth nomination from the prestigious Insight Astronomy Photographer of the Year competition, an annual celebration of the most beautiful and spectacular visions of the cosmos by astrophotographers worldwide. The 2015 competition received 2700 spectacular entries from over 60 countries and the winners will be announced 17 September.
