An Aurora Cupcake with a Milky Way Topping

This sky looked delicious. Double auroral ovals were captured above the town lights of Östersund, Sweden, last week. Pictured above, the green ovals occurred lower to the ground than violet aurora rays above, making the whole display look a bit like a cupcake. To top it off, far in the distance, the central band or our Milky Way Galaxy slants down from the upper left. The auroras were caused by our Sun ejecting plasma clouds into the Solar System just a few days before, ionized particles that subsequently impacted the magnetosphere of the Earth. Aurora displays may continue this week as an active sunspot group rotated into view just a few days ago.

Competition for ecological niches can limit the evolution of new species, causing the rate of speciation to slow or even stop as the available niches fill up. The study focussed on the evolution and diversification of songbirds by combining decades of field studies, DNA analyses and other research.

"Today, there are roughly 5000 oscine species, comprising almost half of all modern bird species, many of which began differentiating within the first 10-12 million years of their explosive climate-triggered radiation. Currently, there are nearly as many songbird species as there are mammalian species."
