NGC 2442: Galaxy in Volans

Copyright: Mike Selby Distorted galaxy NGC 2442 can be found in the southern constellation of the flying fish, (Piscis) Volans. Located about 50 million light-years away, the galaxy’s two spiral arms extending from a pronounced central bar give it a hook-shaped appearance in this deep and colorful image, with foreground stars scattered across the telescopic […]

M78: Reflecting Blue in a Sea of Red

Copyright: Daniel McCauley In the vast Orion Molecular Cloud complex, several bright blue nebulas are particularly apparent. Pictured here in the center are two of the most prominent reflection nebulas – dust clouds lit by the reflecting light of bright embedded stars. The more famous nebula is M78, in the image center, cataloged over 200 […]

Orion’s Treasures over Snowy Mountains

Copyright: Włodzimierz Bubak; Text: Ogetay Kayali (MTU) Rising over a frozen valley in the Tatra Mountains, the familiar stars and nebulas of Orion dominate this wide-field nightscape. The featured deep photo was taken in southern Poland’s highest mountain range last month, where dark skies and alpine terrain combined to reveal both Earth’s rugged beauty and […]

NGC 55: A Galaxy of Nebulas

Copyright: Wolfgang Promper; Text: Ogetay Kayali (MTU) Can you see nebulas in other galaxies? Yes, some nebulas shine brightly enough — if you know how to look. Clouds of hydrogen and oxygen emit light at very specific colors, and by isolating them, astronomers and astrophotographers can reveal structures that would otherwise be too faint to […]

Phobos: Doomed Moon of Mars

This moon is doomed. Mars, the red planet named for the Roman god of war, has two tiny moons, Phobos and Deimos, whose names are derived from the Greek for Fear and Panic. These Martian moons may well be captured asteroids originating in the main asteroid belt between Mars and Jupiter or perhaps from even […]

Earthset from Orion

ght billion people are about to disappear in this snapshot from space taken on 2022 November 21. On the sixth day of the Artemis I mission, their home world is setting behind the Moon’s bright edge as viewed by an external camera on the outbound Orion spacecraft. Orion was headed for a powered flyby that […]

Planetary Nebula Abell 7

Copyright: Martin Pugh Very faint planetary nebula Abell 7 is about 1,800 light-years distant. It lies just south of Orion in planet Earth’s skies toward the constellation Lepus, The Hare. Posing with scattered Milky Way stars, its generally simple spherical shape about 8 light-years in diameter is revealed in this deep telescopic image. The beautiful […]

LDN 1622: Dark Nebula in Orion

Copyright: Chris Fellows The silhouette of an intriguing dark nebula inhabits this cosmic scene. Lynds’ Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only visible in long telescopic exposures of the region. In contrast, a brighter reflection nebula, vdB 62, is more easily seen just above the dusty dark nebula. […]

Barred Spiral Galaxy NGC 1365 from Webb

A mere 56 million light-years distant toward the southern constellation Fornax, NGC 1365 is an enormous barred spiral galaxy about 200,000 light-years in diameter. That’s twice the size of our own barred spiral Milky Way. This sharp image from the James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) reveals stunning details of this magnificent spiral in […]

Io in True Color

The strangest moon in the Solar System is bright yellow. The featured picture, an attempt to show how Io would appear in the “true colors” perceptible to the average human eye, was taken in 1999 July by the Galileo spacecraft that orbited Jupiter from 1995 to 2003. Io’s colors derive from sulfur and molten silicate […]

CTB 1: The Medulla Nebula

What powers this unusual nebula? CTB 1 is the expanding gas shell that was left when a massive star toward the constellation of Cassiopeia exploded about 10,000 years ago. The star likely detonated when it ran out of elements, near its core, that could create stabilizing pressure with nuclear fusion. The resulting supernova remnant, nicknamed […]

Jupiter from the Webb Space Telescope

This infrared view of Jupiter by Webb is illuminating. High-resolution infrared images of Jupiter from the James Webb Space Telescope (Webb) reveal, for example, differences between high-floating bright clouds — including the Great Red Spot — and low-lying dark clouds. Also clearly visible in the featured Webb image are Jupiter’s dust ring, bright auroras at […]

Apollo 14: A View from Antares

Apollo 14’s Lunar Module Antares landed on the Moon on February 5, 1971. Toward the end of the stay astronaut Ed Mitchell snapped a series of photos of the lunar surface while looking out a window, assembled into this detailed mosaic by Apollo Lunar Surface Journal editor Eric Jones. The view looks across the Fra […]

NGC 7023: The Iris Nebula

Copyright: Justus Falk These cosmic clouds have blossomed 1,300 light-years away in the fertile starfields of the constellation Cepheus. Called the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers. Still, this deep telescopic image shows off the Iris Nebula’s range of colors and symmetries embedded in surrounding fields […]

Plato and the Lunar Alps

Copyright: Luigi Morrone The dark-floored, 95 kilometer wide crater Plato and sunlit peaks of the lunar Alps (Montes Alpes) are highlighted in this this sharp telescopic snapshot of the Moon’s surface. While the Alps of planet Earth were uplifted over millions of years as continental plates slowly collided, the lunar Alps were likely formed by […]
