AR2835: Islands in the Photosphere

Awash in a sea of incandescent plasma and anchored in strong magnetic fields, sunspots are planet-sized dark islands in the solar photosphere, the bright surface of the Sun. Found in solar active regions, sunspots look dark only because they are slightly cooler though, with temperatures of about 4,000 kelvins compared to 6,000 kelvins for the surrounding solar surface. These sunspots lie in active region AR2835. The largest active region now crossing the Sun, AR2835 is captured in this sharp telescopic close-up from July 1 in a field of view that spans about 150,000 kilometers or over ten Earth diameters. With powerful magnetic fields, solar active regions are often responsible for solar flares and coronal mass ejections, storms which affect space weather near planet Earth. via NASA https://ift.tt/2SHLVwF

Wikipedia article of the day for July 2, 2021

Wikipedia article of the day is Green rosella. Check it out: Article-Link Summary: The green rosella (Platycercus caledonicus) is a parrot native to the Australian state of Tasmania and some Bass Strait islands. The species was described by the German naturalist Johann Friedrich Gmelin in 1788. At up to 37Β cm (14.5Β in) long, it is the largest species in its genus. Its underparts, neck and head are yellow, with a red band above the beak and violet-blue cheeks. The back is mostly black and green, and its long tail blue and green. The female has duller yellow plumage and more prominent red markings, as well as a smaller beak. Found in a wide range of habitats with some form of tree cover, the green rosella is predominantly herbivorous, consuming seeds, berries, nuts, fruits, and flowers, but it may also eat insect larvae and insects such as psyllids. Nesting takes place in tree hollows. The green rosella is widespread across Tasmania, but the King Island subspecies has been classed as vulnerable.
