2023年12月28日 Jupiter and the Geminid Image Credit & Copyright: Gaurav Singh Explanation: For a brief moment, this brilliant fireball meteor outshone Jupiter in planet Earth’s night. The serendipitous image was captured while hunting meteors under cold Canadian skies with a camera in timelapse mode on December 14, near the peak of the Geminid meteor shower. The Geminid meteor shower, asteroid 3200 Phaethon’s annual gift, always arrives in December. Dust shed along the orbit of the mysterious asteroid causes the meteor streaks, as the vaporizing grains plow through our fair planet’s upper atmosphere at 22 kilometers per second. Of course Geminid shower meteors appear to radiate from a point in the constellation of the Twins. That’s below and left of this frame. With bright Jupiter on…

2023年12月9日 Pic du Pleiades Image Credit & Copyright: Jean-Francois Graffand Explanation: Near dawn on November 19 the Pleiades stood in still dark skies over the French Pyrenees. But just before sunrise a serendipitous moment was captured in this single 3 second exposure; a bright meteor streak appeared to pierce the heart of the galactic star cluster. From the camera’s perspective, star cluster and meteor were poised directly above the mountain top observatory on the Pic du Midi de Bigorre. And though astronomers might consider the Pleiades to be relatively close by, the grain of dust vaporizing as it plowed through planet Earth’s upper atmosphere actually missed the cluster’s tight grouping of young stars by about 400 light-years. While recording a night sky timelapse series, the…
冰岛上空的火流星
2023年9月16日 Fireball over Iceland Image Credit & Copyright: Jennifer Franklin Explanation: On September 12, from a location just south of the Arctic Circle, stones of Iceland’s modern Arctic Henge point skyward in this startling scene. Entertaining an intrepid group of aurora hunters during a geomagnetic storm, alluring northern lights dance across the darkened sky when a stunning fireball meteor explodes. Awestruck, the camera-equipped skygazers captured video and still images of the boreal bolide, at its peak about as bright as a full moon. Though quickly fading from view, the fireball left a lingering visible trail or persistent train. The wraith-like trail was seen for minutes wafting in the upper atmosphere at altitudes of 60 to 90 kilometers along with the auroral glow. Tomorrow’s picture: Magnified…

2023年8月23日 The Meteor and the Galaxy Credit & Copyright: Jose Pedrero Explanation: It came from outer space. It — in this case a sand-sized bit of a comet nucleus — was likely ejected many years ago from Sun-orbiting Comet Swift-Tuttle, but then continued to orbit the Sun alone. When the Earth crossed through this orbit, the piece of comet debris impacted the atmosphere of our fair planet and was seen as a meteor. This meteor deteriorated, causing gases to be emitted that glowed in colors emitted by its component elements. The featured image was taken last week from Castilla La Mancha, Spain, during the peak night of the Perseids meteor shower. The picturesque meteor streak happened to appear in the only one of 50 frames…
