The observation period features lunar appulses with Saturn, Neptune, and Uranus, complemented by transits of Jupiter's Galilean moons (Io and Europa) and their shadows across the gas giant's disk.

Star-forming galaxies, including ours, are rich in elements — and secrets. Stars come to life fastest in the early histories of such galaxies, but this process doesn’t last at such a high rate forever ...

A new extreme trans-Neptunian object (ETNO), designated 2023 KQ14 (Ammonite), has been discovered, representing only the fourth known sednoid – a class of ETNOs with highly distant and elongated ...

Mercury is currently observable as a bright –0.6 magnitude object in the predawn sky, though its visibility is rapidly decreasing as it approaches superior conjunction in late January. Optimal ...

Early understanding of the Milky Way's shape was limited by our internal perspective, initially assuming a typical spiral structure. In 2005, the GLIMPSE survey, utilizing data from the Spitzer Space ...

During their historic first crewed mission orbiting the Moon, the Apollo 8 astronauts Frank Borman, Jim Lovell, and Bill Anders performed a Christmas Eve broadcast, reciting the initial ten verses of ...

New James Webb Space Telescope (JWST) observations provide strengthened evidence for the presence of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) in the atmosphere of exoplanet K2-18 b, ...

Earth's orbit is an ellipse, not a perfect circle. Earth's distance from the Sun varies by about 3 million miles throughout the year. Earth's orbit's semimajor axis is approximately 93 million miles.

The collection documents various transient solar system events, including a dynamically tailed Comet Lemmon, a seven-planet alignment, and two distinct total lunar eclipses, one of which was ...

European regulators issued an Emergency Airworthiness Directive grounding specific Airbus A319, A320, and A321 aircraft after an "uncommanded and limited pitch down" incident on a JetBlue flight, ...

Hundreds of millions of debris fragments zip around Earth at speeds exceeding 15,000 mph, posing a constant threat to astronauts and spacecraft. Thanks to prohibitive costs, no one is bothering to ...

Apollo mission lunar samples provided crucial data, initially intended to test existing Moon formation theories (capture, co-formation, fission), but ultimately leading to the development of the Giant ...
