During a total lunar eclipse, the Moon remains faintly visible due to the refraction and scattering of sunlight by Earth's atmosphere. The color observed during totality (ranging from red to brown) is ...

January presents optimal viewing conditions for Jupiter, which reaches opposition on the 10th in Gemini at magnitude -2.7, offering its largest apparent diameter (47") and opportunities to observe ...

Because rogue planets don’t orbit a host star, they can’t be found using astronomers’ typical go-to methods: radial velocity or transits. (Radial velocity measures the way a star wobbles as an unseen ...

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.

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 ...

The article details a significant astronomical event: the transit of Jupiter's moon Io and its shadow across the gas giant's disk, observed overnight from December 27th into December 28th. The ingress ...

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 ...

Legendary astronaut James “Jim” Lovell, whose steady command during the harrowing Apollo 13 mission captivated the world, died Friday in Lake Forest, Illinois. He was 97. A veteran of four ...

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 ...
