Telescope vs monocular: Which should I buy? Total lunar eclipse March 2025 — When and where to see the next 'Blood Moon' lunar eclipse What should I look for in a monocular for stargazing? How The Bad Batch became key to the Star Wars lore How to use monoculars for stargazing Gears ...
According to Einstein, gravity is a distortion of spacetime, the fabric of the universe itself. Mass warps space, like a bowling ball creates an indent on a bed sheet, and more massive objects like stars or black holes warp space with effects easily observed in a telescope – the b...
What Is Dark Matter? The Milky Way as captured by NASA's Spitzer Space Telescope.Credit: NASA, JPL-Caltech, Susan Stolovy (SSC/Caltech) Of all the sciences, physics is unique in that it can come to a broad consensus with math alone—very little tactile evidence required. Never has ...
Observations of a pulsar's rays using the VLT telescope in Chile showed evidence of a vacuum birefringence. This is an interesting feature of optics in which light passes through a special material layer before returning to the original conditions it had been before entering. As the light goes ...
NASA hopes it will see all the way back to when the first galaxies formed, nearly 13.6 billion years ago. And unlike Hubble, which sees mainly in thevisible waveband, JWST is an infrared telescope — a big advantage when looking at very distant galaxies. The expansion of the universe means...
