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 ...

NGC 7662, a planetary nebula colloquially known as the Blue Snowball, is located within the northern region of the constellation Andromeda, approximately 4.5° east of the star Omicron Andromedae.

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 ...

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 ...

Robert Aitken, born in 1864, overcame childhood health challenges, including progressive deafness, to earn a B.A. in mathematics in 1887 and subsequently teach mathematics and astronomy. He embarked ...

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 ...

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 ...

Asteroid 40 Harmonia will reach opposition at 10 A.M. EST on January 1st, becoming observable with binoculars or a telescope in Gemini, positioned approximately 2.5° southeast of Mebsuta. Observation ...

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 ...

The article details the observation of NGC 2264, designated as the Christmas Tree Cluster, on December 24. This celestial object is identified as a magnitude 3.9 combination open cluster and ...

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 ...
