Halloween is an astronomy holiday and spooky shapes always seem to lurk in planet Earth's night skies. In fact, near the center of this telescopic view toward the constellation Cassiopeia these swept-back interstellar clouds IC 59 (left) and IC 63 look ghostly on a cosmic scale.

Can you see the bat? It haunts this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. Оценка: 5.0 [голосов: 1]
How many bright tails does Comet Lemmon have? Two. In the featured image it appears to have three, but why? The reason is that the zigzagging brown filament is a persistent meteor train that by luck appeared in front of the distant comet C/2025 A6 (Lemmon). Оценка: 5.0 [голосов: 1]
Halloween's origin is ancient and astronomical. Since the fifth century BC, Halloween has been celebrated as a cross-quarter day, a day halfway between an equinox (equal day / equal night) and a solstice (minimum day / maximum night in the northern hemisphere). Оценка: 5.0 [голосов: 1]
A mere 390 light-years away, Sun-like stars and future planetary systems are forming in the Rho Ophiuchi molecular cloud complex, the closest star-forming region to our fair planet. The James Webb Space Telescope's NIRCam peered into the nearby natal chaos to capture this infrared image at an inspiring scale. Оценка: 5.0 [голосов: 1]
A star forming region cataloged as NGC 2264, this beautiful but complex arrangement of interstellar gas and dust is about 2,700 light-years distant in the faint but fanciful constellation Monoceros, the Unicorn. Seen... Оценка: 5.0 [голосов: 1]
What are these little red dots (LRDs)? Nobody knows. Discovered only last year, hundreds of LRDs have now been found by the James Webb Space Telescope in the early universe. Although extremely faint, LRDs are now frequently identified in deep observations made for other purposes. Оценка: 5.0 [голосов: 1]
В лунном океане Бурь расположен хорошо заметный ударный кратер Коперник. Он находится в центре этого телескопического портрета, запечатлевшего свет и тени на Луне. Картинка создана сложением видеокадров, снятых 14 апреля в 3:30 по Всемирному времени, когда лунный терминатор – граница между днем и ночью – проходил через середину кратера диаметром в 93 километра.
