Beyond one of Orion's extended solar arrayslies dark, smooth, terrain along thewestern edge of the Oceanus Procellarum.Prominent on the lunar nearsideOceanus Procellarum,the Ocean of Storms, is the largest of theMoon's lava-flooded maria.The lunar terminator, shadow line between lunar night and day,runs along the left of this frame.The 41 kilometer diametercrater Mariusis top center, with raycrater Keplerpeeking in at the edge, just right of the solar array wing.Kepler's bright rays extend to the north and west, reaching thedark-floored Marius.By December 11, 2022 the Orion spacecraft hadreached its home world.The historic Artemis 1 mission ended with Orion's successful splashdown inplanet Earth'swater-flooded Pacific Ocean.

Vega and Comet 12P Pons-Brooks

Astronomy Picture of the Day Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2023 December 8 Vega and Comet 12P/Pons-Brooks Image Credit &Copyright:Dan Bartlett Explanation: On December 4, periodicComet 12P/Pons-Brooksshared thistelescopic field of viewwith Vega, alpha star of the northern constellation Lyra.Fifth brightest star in planet Earth's night,Vega is some 25light-years distant whilethe much fainter comet was about 21 light-minutes away.In recent months,outbursts have caused dramatic increasesin brightness for Pons-Brooks though.Nicknamed the Devil Comet for its hornlike appearance,fans of interstellar spaceflight have also suggestedthe distorted shape of this comet's large coma looks like theMillenium Falcon.A Halley-type comet, 12P/Pons-Brookslast visited the innerSolar System in 1954.Its next perihelion passage or closest approach to the Sunwill be April 21, 2024.That's just two weeks after the April 8 totalsolar eclipse path crosses North America.But, highly inclined to the Solar System's ecliptic plane,the orbit ofperiodic Comet 12P/Pons-Brookswill never cross the orbit of planet Earth.

Startrails over Beijing Ancient Observatory

Astronomy Picture of the Day Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2023 December 2 Startrails over Beijing Ancient Observatory Image Credit &Copyright:Jeff Dai(TWAN) Explanation: You can takea subway ride to visit thisobservatory in Beijing, Chinabut you won't find any telescopes there.Starting in the 1400s astronomers erected devices at theBeijing Ancient Observatorysite to enable them to accurately measure and track the positions ofnaked-eye stars and planets.Some of the large, ornateastronomical instrumentsare still standing.You can even see stars from the star observation platform today,but now only the very brightestcelestial beacons are visibleagainst the city lights.In this time series of exposures from a camera fixed to a tripodto record graceful arcing startrails,the brightest trail is actually the Moon.Its broad arc is seen behind the ancient observatory's brassarmillary sphere.Compare this picturefrom the Beijing Ancient Observatory taken in September 2023 toone taken in 1895.

Planet Earth from Orion

Astronomy Picture of the Day Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2023 November 18 Planet Earth from Orion Image Credit:NASA,Artemis I Explanation: One year agoa Space Launch System rocket left planet Earthon November 16, 2022 at 1:47am EST carrying the Orion spacecraft on theArtemis I mission, the first integrated test of NASA’s deep spaceexploration systems.Over an hour afterliftoff from Kennedy Space Center'shistoricLaunch Complex 39B, one of Orion'sexternal video camerascaptured this view of its newperspective from space.In the foreground are Orion's Orbital Maneuvering System engineand auxillary engines,at the bottom of the European Service Module.Beyond one of the module's 7-meter long extended solar array wingslies the spacecraft'sbeautiful home world.Making close flybys of thelunar surface and reaching aretrograde orbit 70,000 kilometers beyond the Moon, theuncrewed Artemis I missionlasted over 25 days,testing capabilities to enable human exploration of the Moon and Mars.Building on thesuccessof Artemis I,no earlier than November 2024the Artemis II missionwith a crew of 4 will venture around the Moon and back again.
