Refractor telescopes use specialised lenses to gather and focus light into an image, displaying a magnified sky view. In contrast, reflector telescopes use curved mirrors to reflect light onto the ...

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...

The primary objective of this spacewalk is to replace critical hardware and repair the Neutron star Interior Composition Explorer (NICER) X-ray telescope. Listen to Story Williams and Hague will ...

He invented the first refracting telescope allowing him to observe the motions of the planets and was the first even to attempt measuring the speed of light. His work on motion helped his predecessor, ...

With three spectacular cosmic events happening, January is the perfect time to pick up a telescope. We've rounded up the best telescopes for beginners, to suit a range of budgets. January is ...

Stephen McAllister, a physics teacher from Port Glasgow, went viral last year after snapping stunning photos of space using his phone and an £80 telescope from Aldi. Now, using his trusty setup ...

Researchers used the James Webb Space Telescope, a collaboration of NASA and its European and Canadian counterparts, to find that the ancient pulse, like a cosmic flashlight, had lit up never ...

Of all the mysteries that the massive James Webb Space Telescope has seen so far in the early universe, one of the strangest are objects that astronomers now call "little red dots." Like the ...
