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

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 ...

November presents a dynamic celestial calendar, with Mercury transitioning from the evening to morning sky and Venus's visibility diminishing throughout the month. The gas giants Jupiter, Saturn, ...

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 ...

The Biosphere 2 facility, specifically its Landscape Evolution Observatory (LEO), serves as a research platform to investigate how life transforms landscapes, ranging from local environments to ...

October features significant planetary phenomena, including two transits of Titan across Saturn and recurring tandem transits of Io and Europa across Jupiter's disk, often with their shadows. The ...

The article highlights current observational opportunities for asteroid 4 Vesta and the globular cluster M80, located in the constellation Scorpius. Optimal viewing is recommended southwest, ...

Voyager 1 and 2, launched in 1977, have traversed the heliopause and are currently in interstellar space, with Voyager 1 significantly farther from the Sun due to its higher velocity. The Oort Cloud, ...

The August full moon, also known as the Sturgeon Moon, reached its full phase at 3:55 A.M. EDT. Observing the full moon presents challenges due to its brightness, which can hinder dark adaptation and ...

NASA plans to deploy a 100kW nuclear reactor on the Moon by 2030, significantly increasing the power output from previous 40kW designs, driven by a desire to establish a sustainable human presence and ...

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 ...

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 ...
