On a specified date, the Moon will pass 0.8° north of Venus and 1.3° north of Regulus (magnitude 1.4), with Venus and Regulus separated by less than 0.5°. This celestial trio will rise around 4:30 A.M ...

Data from NASA's Dawn mission, analyzed via thermal and chemical models, suggests Ceres possessed a long-lasting internal heat source driven by radioactive element decay. This heat source, reaching ...

SpaceX's Starship Flight 9, though achieving orbit, failed due to a damaged pressurization system diffuser on the main fuel tank, leading to a chain of events including payload door failure and loss ...

Temperature is a measure of the average energy of a collection of particles. (This is in contrast to kinetic energy, which is a measure of the energy carried by a single particle.) So, to answer a ...

The 9mm Nagler Type 7 eyepiece offers a mix of sharpness and correction for deep-sky objects. This new eyepiece presents an 82° apparent field of view. It is designed with comfort in mind for eyeglass ...

Shocked quartz, indicative of extreme pressure and temperature, was discovered at three prominent Clovis culture archaeological sites (Murray Springs, Blackwater Draw, Arlington Canyon). The presence ...
