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 ...

Christian Doppler (1803-1853) studied mathematics, physics, and astronomy, eventually holding academic positions including a professorship and the inaugural directorship of the Institute of Physics in ...

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 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 ...

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, ...

3I/ATLAS is an interstellar object, originating outside our solar system. It's traveling much faster than previously observed interstellar objects. Scientists believe it may have formed in a different ...

‘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 ...

I wake up to a chime from my smartphone. Bleary-eyed, I check it — and jolt awake upon seeing an automated email from the MeerKAT radio telescope in South Africa. The subject line reads: “AT 2018xxx ...

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 ...
