Lynds Dark Nebula 1251

Copyright: Stefano Attalienti Stars are forming in Lynds Dark Nebula (LDN) 1251. About 1,000 light-years away and drifting above the plane of our Milky Way galaxy, the dusty molecular cloud is part of a complex of dark nebulae mapped toward the Cepheus flare region. Across the spectrum, astronomical explorations of the obscuring interstellar clouds reveal […]

Earthset from Orion

Copyright: ght billion people are about to disappear in this snapshot from space. Taken on November 21, the sixth day of the Artemis 1 mission, their home world is setting behind the Moon’s bright edge as viewed by an external camera on the outbound Orion spacecraft. The Orion was headed for a powered flyby that […]

A Double Star Cluster in Perseus

Copyright: Tommy Lease Few star clusters this close to each other. Visible to the unaided eye from dark sky areas, it was cataloged in 130 BC by Greek astronomer Hipparchus. Some 7,000 light-years away, this pair of open star clusters is also an easy binocular target, a striking starfield in the northern constellation of the […]

The Butterfly Nebula from Hubble

Copyright: Stars can make beautiful patterns as they age — sometimes similar to flowers or insects. NGC 6302, the Butterfly Nebula, is a notable example. Though its gaseous wingspan covers over 3 light-years and its estimated surface temperature exceeds 200,000 degrees C, the aging central star of NGC 6302, the featured planetary nebula, has become […]

Airglow Ripples over Tibet

Copyright: Jeff Dai Why would the sky look like a giant target? Airglow. Following a giant thunderstorm over Bangladesh in late April, giant circular ripples of glowing air appeared over Tibet, China, as pictured here. The unusual pattern is created by atmospheric gravity waves, waves of alternating air pressure that can grow with height as […]

Artemis 1 Moonshot

Copyright: John Kraus When the Artemis 1 mission’s Orion spacecraft makes its November 21 powered flyby of the Moon, denizens of planet Earth will see the Moon in a waning crescent phase. The spacecraft will approach to within about 130 kilometers of the lunar surface on its way to a distant retrograde orbit some 70,000 […]

The Protostar within L1527

Copyright: The protostar within dark cloud L1527 is a mere 100,000 years old, still embedded in the cloud of gas and dust that feeds its growth. In this NIRCam image from the James Webb Space Telescope, the dark band at the neck of the infrared nebula is a thick disk that surrounds the young stellar […]

Wolf’s Cave Nebula

Copyright: Gianni Lacroce The mysterious blue reflection nebula found in catalogs as VdB 152 or Ced 201 really is very faint. It lies at the tip of the long dark nebula Barnard 175 in a dusty complex that has also been called Wolf’s Cave. At the center of this deep telescopic view, the cosmic apparitions […]

NGC 7380: The Wizard Nebula

Copyright: Ioan Popa What powers are being wielded in the Wizard Nebula? Gravitation strong enough to form stars, and stellar winds and radiations powerful enough to create and dissolve towers of gas. Located only 8,000 light years away, the Wizard nebula, featured here, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, […]

Flying Saucer Crash Lands in Utah Desert

Copyright: A flying saucer from outer space crash-landed in the Utah desert after being tracked by radar and chased by helicopters. The year was 2004, and no space aliens were involved. The saucer, pictured here, was the Genesis sample return capsule, part of a human-made robot Genesis spaceship launched in 2001 by NASA itself to […]

Eclipse in the City

Copyright: Stan Honda A darker Moon sets over Manhattan in this night skyscape. The 16 frame composite was assembled from consecutive exposures recorded during the November 8 total lunar eclipse. In the timelapse sequence stars leave short trails above the urban skyline, while the Moon remains immersed in Earth’s shadow. But the International Space Station […]

Blood Moon, Ice Giant

Copyright: Ryan Han On November 8 the Full Moon turned blood red as it slid through Earth’s shadow in a beautiful total lunar eclipse. During totality it also passed in front of, or occulted, outer planet Uranus for eclipse viewers located in parts of northern America and Asia. For a close-up and wider view these […]

Total Lunar Eclipse

Copyright: The beginning, middle, and end of a journey through planet Earth’s colorful umbral shadow is captured in this timelapse composite image of a total lunar eclipse. Taken on November 8 from Kitt Peak National Observatory this eclipse’s 1 hour and 25 minute long total phase starts on the right and finishes on the left. […]

The Asymmetric Nebula Surrounding Wolf-Rayet Star 18

Copyright: Alex Woronow Why does the nebula around the star WR-18 shine brighter on one side? Also known as NGC 3199, this active star and its surrounding nebula lie about 12,000 light-years away toward the nautical southern constellation of Carina. The featured deep image has been highly processed to bring out filamentary details of the […]

Galaxies: Wild’s Triplet from Hubble

Copyright: How many galaxies are interacting here? This grouping of galaxies is called the Wild Triplet, not only for the discoverer, but for the number of bright galaxies that appear. It had been assumed that all three galaxies, collectively cataloged as Arp 248, are interacting, but more recent investigations reveal that only the brightest two […]
