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

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 ...

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 ...

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 Chang'e 5 mission employed Lunar Orbit Rendezvous (LOR), a method similar to the Apollo missions, involving separate modules for lunar descent, ascent, and Earth return, achieving efficient fuel ...

‘Oumuamua, the first interstellar object detected within our solar system, exhibited unusual characteristics including an extreme shape and non-gravitational acceleration, prompting diverse hypotheses ...

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) ...
