Discovered on July 1, 2025, this comet does not follow a classical orbit around the Sun, but a so-called hyperbolic ...

Newton's theory of gravity posited instantaneous gravitational attraction, successfully predicting planetary orbits. Einstein's special relativity challenged this, necessitating the development of ...

Observations from the European satellite Gaia allow for the refutation of a controversial alternative theory and support the ...

NASA's Hubble Space Telescope has a treasure trove of stunning cosmic images showcasing various forms of galaxies, stars, and other space objects. The space agency recently released an image flooded ...

Pennsylvania’s largest amusement park is adding a new attraction in 2025. Hersheypark is adding the Twizzlers Twisted Gravity attraction when it opens the park next year. In the just over minute-long ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

Gravity may feel like one of the most familiar forces, but it’s actually among those we understand least. We know our current model of gravity is inconsistent with quantum mechanics. It also fails to ...

It's fun to think about how we know stuff. For instance, the sun has a mass of about 2 x 10 30 kilograms. That is such an enormous mass that it's difficult to comprehend. And if it's so difficult for ...

In 1797 Henry Cavendish, one of Great Britain’s leading scientists, built a contraption to weigh the world. At the time, Earth’s mass was unknown, as was its composition. Was it mostly solid rock? Did ...
