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 ...

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 ...

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 ...

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 ...

The existence of "Planet Nine," a hypothetical planet in the outer solar system, is supported by indirect evidence such as the unusual clustering of orbits of extreme trans-Neptunian objects (ETNOs) ...

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 ...
