德国上空的流星与极光

A night sky filled with stars is colored partly purple by an aurora. Also visible are several streaks which are meteors in this image composite. In the foreground is a field and lone tree. Part of the tree slants at the nearly the same angle of the meteor streaks. Please see the explanation for more detailed information.

A night sky filled with stars and the band of our Milky Way galaxy is shown also filled with many streaks. The short streaks are all coordinated and together indicate a flow from the top of the image to the bottom. In the foreground at the bottom of the frame is Stonehenge. Please see the explanation for more detailed information.

2023年8月9日 Meteor Shower: Perseids from Perseus Credit & Copyright: Petr Horálek / Institute of Physics in Opava Explanation: This is a good week to see meteors. Comet dust will rain down on planet Earth, streaking through dark skies during peak nights of the annual Perseid Meteor Shower. The featured composite image was taken during the 2018 Perseids from the Poloniny Dark Sky Park in Slovakia. The dome of the observatory in the foreground is on the grounds of Kolonica Observatory. Although the comet dust particles travel parallel to each other, the resulting shower meteors clearly seem to radiate from a single point on the sky in the eponymous constellation Perseus. The radiant effect is due to perspective, as the parallel tracks appear to converge at…

2022年8月7日 Meteor before Galaxy Image Credit & Copyright: Fritz Helmut Hemmerich Explanation: What’s that green streak in front of the Andromeda galaxy? A meteor. While photographing the Andromeda galaxy in 2016, near the peak of the Perseid Meteor Shower, a small pebble from deep space crossed right in front of our Milky Way Galaxy’s far-distant companion. The small meteor took only a fraction of a second to pass through this 10-degree field. The meteor flared several times while braking violently upon entering Earth’s atmosphere. The green color was created, at least in part, by the meteor’s gas glowing as it vaporized. Although the exposure was timed to catch a Perseid meteor, the orientation of the imaged streak seems a better match to a meteor from…

2021年9月28日 Night of the Perseids Video Credit & Copyright: Vikas Chander & Dorje Angchuk; Music: Tea Time via PremiumBeat Explanation: Have you ever experienced a meteor shower? To help capture the wonder, a video was taken during the peak of the recent Perseid meteor shower above the Indian Astronomical Observatory in Hanle, India, high up in the Himalayan mountains. Night descends as the video begins, with the central plane of our Milky Way Galaxy approaching from the left and Earth-orbiting satellites zipping by overhead. During the night, the flash of meteors that usually takes less than a second is artificially extended. The green glow of most meteors is typically caused by vaporizing nickel. As the video continues, Orion rises and meteors flare above the 2-meter…

2021年9月24日 Perseid Outburst at Westmeath Lookout Image Credit & Copyright: Pierre Martin Explanation: This year an outburst of Perseid meteors surprised skywatchers. The reliable meteor shower’s peak was predicted for the night of August 12/13. But persistent visual observers in North America were deluged with a startling Perseid shower outburst a day later, with reports of multiple meteors per minute and sometimes per second in the early hours of August 14. The shower radiant is high in a dark night sky in this composite image. It painstakingly registers the trails of 282 Perseids captured during the stunning outburst activity between 0650 UT (02:50am EDT) and 0900 UT (05:00am EDT) on August 14 from Westmeath Lookout, Ontario. Of course the annual Perseid meteor shower is associated…

2021年8月16日 Perseid Meteor, Red Sprites, and Nova RS Ophiuchus Image Credit & Copyright: Daniel Korona Explanation: This was an unusual sky. It wasn’t unusual because of the central band the Milky Way Galaxy, visible along the image left. Most dark skies show part of the Milky Way. It wasn’t unusual because of the bright meteor visible on the upper right. Many images taken during last week’s Perseid Meteor Shower show meteors, although this Perseid was particularly bright. This sky wasn’t unusual because of the red sprites, visible on the lower right. Although this type of lightning has only been noted in the past few decades, images of sprites are becoming more common. This sky wasn’t unusual because of the nova, visible just above the image…
