Hunt today unveiled a trio of new wheelsets amid a wider announcement around its plans for environmental sustainability. In short, this means that, in addition to a company-wide commitment to meet certain sustainability targets, three of the most popular wheelsets have undergone a redesign using recycled materials, less resource-intensive manufacturing processes, sustainability-focused specification choices and … Read more
A surprisingly low methane reservoir could explain how a planet around a nearby star became strangely puffy, according to new observations from the James Webb Space Telescope (JWST). The finding shows that planetary atmospheres can inflate to remarkable amounts without resorting to esoteric theories of planet formation, astronomers say. “The Webb data tells us that … Read more
Our solar system is a pretty busy place. There are millions of objects moving around – from planets to moons, to comets and asteroids. And every year we discover more and more objects (usually small asteroids or fast comets) calling the solar system home. Astronomers had found all eight of the major planets by 1846. … Read more

The artist’s conception of 126 planets in the latest TESS-Keck Survey catalog is based on data such as the planet’s radius, mass, density and temperature. Question marks represent planets that require more data for full characterization. Credit: WM Keck Observatory/Adam … 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

Astronomers have discovered an Earth-sized planet that is receiving so much radiation that its atmosphere has long since eroded away, leaving it barren. Life as we know it cannot exist on this sizzling world, but astronomers are interested in it for another reason: for the first time, they may be able to see the geology … Read more
WASP-193b, a new exoplanet, is 50% larger than Jupiter, but seven times less massive, with an extremely low density comparable to cotton candy. Discovered by WASP and confirmed by observatories in Chile, the formation challenges current planetary theories and requires further research. Credit: SciTechDaily.com This exoplanet is larger but seven times less massive than Jupiter … Read more
New evidence strongly suggests the existence of a Planet 9 on the edge of our solar system. Image via Solen Feyissa/Unsplash. New evidence for Planet 9 Evidence is growing that a planet the size of Neptune – Planet 9 – is hiding deep in the outskirts of our solar system. Researchers from Caltech, Université Côte … Read more
