At least two ingredients are needed to make jets — rotation and magnetic fields — and these produce the ubiquitous laserlike jets we see.

Stephan's Quintet, discovered in 1877 by French astronomer Edouard Stephan in the constellation Pegasus, exemplifies the enhanced detail observable through larger astronomical apertures. The group ...

Early December evenings feature Saturn in the northwest, displaying diminished brightness attributable to its greater distance from Earth and a narrowing of its ring system; telescopic observations ...

Celestron introduces the Moon Mission 100mm Tabletop Dobsonian, a 4-inch f/4 reflector telescope that includes two eyepieces, a finder scope, and a Moon filter, weighing 5.3 pounds with an optical ...

On November 25, Jupiter will be observable approximately 10° above the eastern horizon by 9 P.M. local time, positioned 7° south of Pollux and visible near Gemini's twin stars, Castor and Pollux.

NGC 7789 is an open star cluster situated in Cassiopeia, discovered by Caroline Herschel in 1783, and is also known by appellations such as "Caroline’s Haystack." This celestial object is a relatively ...

On November 22, Titan will transit Saturn. The Silver Sliver Galaxy (NGC 891), an edge-on spiral measuring 13’ by 3’ and glowing at magnitude 9.9, is observable 3.5° east of Almach (Gamma Andromedae) ...

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 ...

Black holes are regions of spacetime with gravity so strong that nothing escapes. Black holes grow by consuming nearby matter, slowing their eventual evaporation. Hawking radiation causes black holes ...

‘Oumuamua, the first interstellar object detected within our solar system, exhibited unusual characteristics including an extreme shape and non-gravitational acceleration, prompting diverse hypotheses ...

The origin of Earth's water is a long-standing scientific question, with differing isotopic ratios of deuterium to hydrogen (D/H) in Earth's oceans compared to the early solar system suggesting ...

Several planets, including Mercury, Mars, Venus, Uranus, Neptune, Saturn, and Jupiter, are visible this month. Saturn's moon Titan will cast its shadow on Saturn twice during July. Neptune will be ...
