Source: Pixabay/CC0 Public Domain Tachyons are hypothetical particles that travel at speeds greater than the speed of light. These superluminal particles are the “enfant terrible” of modern physics. Until recently, they were generally considered as entities that did not fit into special relativity. However, an article recently published in Physical assessment D by physicists from … Read more
Source: Pixabay/CC0 Public Domain According to a study by the University of Michigan, up to 60% of objects near Earth could be dark comets. These are mysterious asteroids that orbit the sun in our solar system and probably contain or once contained ice. These asteroids could have been one of the routes for delivering water … Read more
Astronomers have discovered a previously unknown pair of potential satellite galaxies orbiting the Milky Way. The locations of these dwarf galaxies suggest that hundreds of other unknown miniaturized galaxies could be hiding around us — potentially challenging our understanding of the galaxy’s edges. A satellite galaxy is a group of stars, either in a circular … Read more

A newly discovered exoplanet, estimated to have a remarkably moderate surface temperature, is suddenly one of the most intriguing objects in our immediate sky. This Venus-sized rocky world passes by a red dwarf star, offering astronomers a rare opportunity to investigate whether such planets can maintain their atmospheres and possibly support life. How will time … Read more
Mars’ moon Phobos could be a comet — or at least part of it — that was captured by the Red Planet’s gravity long ago, according to a new preprint study based on previously unpublished images. For years, researchers have puzzled over the origins of Phobos and its twin brother, Deimos. Some have theorized that … Read more
On September 29, 2022, NASA’s Juno spacecraft made its closest flyby of Europa, coming within 355 kilometers of the frozen surface of Jupiter’s moon. The close-up view of Europa revealed incredible details of the moon’s chaotic terrain, suggesting the icy crust is not where it once was. The images also showed a newly discovered feature … Read more
