¿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2021 June 13 IFRAME: [2]https://player.vimeo.com/video/67995158?title=0&portrait=0 A Supercell Thunderstorm Over Texas Video Credit & Copyright: [3]Mike Olbinski; Music: Impact Lento (Kevin MacLeod, [4]Incompetech) Explanation: Is that a cloud or an alien spaceship? It's an unusual and sometimes dangerous type of thunderstorm cloud called a [5]supercell. Supercells may spawn damaging [6]tornados, [7]hail, [8]downbursts of air, or [9]drenching rain. Or they may just look impressive. A [10]supercell harbors a [11]mesocyclone -- a rising column of air surrounded by drafts of falling air. [12]Supercells could occur over many places on Earth but are particularly common in [13]Tornado Alley of the USA. [14]Featured here are four time-lapse sequences of a [15]supercell in 2013 rotating above and moving across [16]Booker, [17]Texas. Captured in the video are new clouds forming near the [18]storm center, [19]dust swirling on the ground, [20]lightning flashing in the upper clouds, all while the impressively [21]sculptured complex rotates ominously. Finally, after a few hours, as shown in the final sequence, dense [22]rain falls as the storm begins to die out.
