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

On December 9th, Neptune will attain its stationary point at 7 P.M. EST, marking the conclusion of its retrograde motion. The ice giant will be situated near Saturn and the Circlet of Pisces in the ...

Mercury's visibility is noted to be improving, appearing 7° high an hour before sunrise with a magnitude of –0.3 and a 54% illuminated disk. The planet is approaching its greatest western elongation, ...

The primary observational focus is Jupiter, featuring a transit of its moon Ganymede and its associated shadow. Prior to the transit, Ganymede and Europa will execute a close alignment and pass east ...

On December 3, the Moon reaches perigee, its closest orbital point to Earth, followed by a Full Moon (the December Cold Moon) at 6:14 P.M. EST. This event is identified as a Super Moon, concluding a ...

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 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 ...

Lacerta is a faint constellation located near Cygnus and Cepheus. The star cluster NGC 7243 is near Lacerta's brightest star and is visible with binoculars. NGC 7243 appears as a fuzzy patch of light ...

The Minor Planet Center (MPC) initially classified a near-Earth object (NEO), designated 2018 CN41, as a newly discovered asteroid based on observations from citizen scientists. This was later ...

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 ...
