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

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 ...

A new study proposes that Venus was a "steam world" from its early formation, with surface temperatures too high to support liquid water oceans, contrary to previous hypotheses of a potentially ...

On November 26, Jupiter will execute a passage south of Pollux. Dwarf planet 1 Ceres will achieve a stationary point at 6 P.M. EST in Cetus, subsequently shifting from retrograde to prograde motion, ...

On November 27, Saturn will reach a stationary point in the constellation Aquarius, visible at magnitude 0.9 and positioned 40° high in the southern sky at 8 P.M. EST, with a waxing Moon in close ...

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 ...

Primordial nucleosynthesis during the early universe generated hydrogen, helium, and minor lithium-7 before the cosmos cooled, halting further fusion. Stellar interiors synthesize elements up to iron ...

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 ...
