The journey of astronomical telescopes began in the early 17th century when Galileo Galilei crafted his first refracting ...

Curious about what lies beyond? Join me for an enlightening exploration of the profound relationship between science and the ...

These telescopes can be divided into two different types: Newtonians and Dobsonians. Newtonian reflectors are quite versatile and well-suited to astrophotography, but they require quite a lot of ...

Save over $110 off this Newtonian reflector telescope. We think the Celestron StarSense Explorer DX 130AZ is one of the best budget telescopes, and we rate it as the best overall for under $500.

For instance, in the 17th century, Newtonian optics viewed light as composed of particles. This perspective shifted in the 19th century with the wave theory proposed by Young and Fresnel.

Planets around other stars need to be prepared for extreme weather conditions, according to a new study from NASA's Chandra X ...

Newton was driven by the belief that the path to true knowledge lay in making observations rather than reading books. For example, rather than trust texts on optics, he experimented by sticking a ...

Back in the old days—the really old days—the task of designing materials was laborious. Investigators, over the course of ...

The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight ...

The first black hole that astronomers observed "turning off" just turned back on, releasing jets of hot gas into the cosmos.

As 2024 came to a close, the White House and Congress approved big giveaways to two subsets of state and local government ...

Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's edge.
