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.
In the first billion years of Earth’s history, the planet was bombarded by primordial asteroids, while a faint Sun provided much less heat. A Southwest Research Institute-led team posits that this tumultuous beginning may have ultimately fostered life on Earth, particularly in terms of sustaining liquid water.
On the final day of NAM2015, science writer Kulvinder Singh Chadha investigates a new model that generates accurate predictions of irregularities within the Sun’s 11-year heartbeat, suggesting that solar activity could fall by 60 percent during the 2030s to ‘mini ice age’ conditions. Kulvinder also looks back at the lighter moments and highlights of a successful conference.
A new ice age is coming — if the prediction of a Lomonosov Moscow State University researcher and her colleagues is correct. A model that accurately predicts variations in the Sun’s magnetic field suggests a sharp decline in solar output during the years 2030-2040, producing conditions similar to that existing during the 17th century Maunder minimum.
