Supernumerary Rainbows over New Jersey

Supernumerary Rainbows over New Jersey

Copyright: John Entwistle Yes, but can your rainbow do this? After the remnants of Hurricane Florence passed over the Jersey Shore, New Jersey, USA in 2018, the Sun came out in one direction but something quite unusual appeared in the opposite direction: a hall of rainbows. Over the course of a next half hour, to […]

Saturn at Night

Saturn at Night

Copyright: Saturn is still bright in planet Earth’s night skies. Telescopic views of the distant gas giant and its beautiful rings often make it a star at star parties. But this stunning view of Saturn’s rings and night side just isn’t possible from telescopes closer to the Sun than the outer planet. They can only […]

NGC 6744: Extragalactic Close-Up

NGC 6744: Extragalactic Close-Up

Copyright: Beautiful spiral galaxy NGC 6744 is nearly 175,000 light-years across. That’s larger than the Milky Way. It lies some 30 million light-years distant in the southern constellation Pavo, with its galactic disk tilted towards our line of sight. This Hubble close-up of the nearby island universe spans about 24,000 light-years or so across NGC […]

Lynds Dark Nebula 1251

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

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

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

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

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

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

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

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

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

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 […]
