When does the Sun look like a flower? In a specific color of red light emitted by hydrogen, as featured here, some regions of the solar chromosphere may resemble a rose. The color-inverted image was taken in 2014 October and shows active solar region 2177. The petals dominating the frame are actually magnetically confined tubes of hot plasma called fibrils, some of which extend longer the diameter of the Earth. In the central region many of these fibrils are seen end-on, while the surrounding regions are typically populated with curved fibrils. When seen over the Sun's edge, these huge plasma tubes are called spicules, and when they occur in passive regions they are termed mottles. Sunspot region 2177 survived for several more days before the complex and tumultuous magnetic field poking through the Sun's surface evolved yet again.
I ran ScottishClimbs (https://scottishclimbs.com/) with , and for more than 10 years (and have still not got round to properly shutting it down). It was a lot of work and even more fun. Creating and managing an online community and climbing resource was a unique experience for me and is one of the most rewarding things I have done in my whole life. Nothing but amazing memories.
That time of my life has passed though and I think it's absolutely fucking excellent that someone has decided to pick up the mantle. Even better, it's just as I'm getting back into climbing - the universe has a lovely way of working out sometimes.
Those who know my own feelings about Facebook might be surprised that I actually think it's exactly the right place for SC to live on. From their about page:
> Scottish Climbs rises from the ashes as a Facebook page.
> ScottishClimbs was at one point the beating online heart of Scottish climbing.
> This is an attempt to gather info from all the corners of the Scottish climbing
> community in one online space again.
Come on though guys, you've got to be consistent about there being no space in ScottishClimbs...

What are those red streaks in the sky? While photographing unexpected auroras over a distant thunderstorm, something extraordinary happened: red sprites. This brief instance of rarely imaged high-altitude lightning flashed so bright that it was witnessed by several people independently. Pictured over Minnesota, USA in May 2013, these red sprites likely followed an extremely powerful low-altitude conventional lightning bolt. Captured in the featured frame are a house and electrical pole in the foreground, thick clouds in the lower atmosphere, a lightning storm on the horizon, distant red sprites and green aurora in the upper atmosphere, and distant stars from our local neighborhood of the Milky Way Galaxy. The spectacular image is thought to be only the second known case of sprites and auroras photographed together, and possibly the first in true color.
