The solar system holds many secrets that scientists are still trying to unravel. To help shed light on these mysteries, researchers are turning to space rocks of all kinds that may hold clues to the lost story of our solar system’s past. This approach is already bearing fruit: In October 2023, NASA’s OSIRIS REx mission … Read more
Scientists have spotted the brightest and fastest-growing quasar ever seen — a monster black hole that’s devouring a sun’s-worth of material every day. The brightly burning object, named J0529-4351, weighs between 17 billion and 19 billion solar masses and is located 12 billion light-years from Earth — meaning it dates to a time when the … Read more
Astronomers have discovered that a tiny moon of Saturn, named Mimas, may harbor a hidden liquid ocean beneath its thick icy shell and may thus have the conditions for habitability. This shocking finding radically changes the definition of what an ocean moon can be, and could ultimately redefine our search for alien life on moons … Read more
Scientists are now inspecting snagged, bagged and tagged bits and pieces from asteroid Bennu, the cosmic mother lode delivered by NASA’s Origins, Spectral Interpretation, Resource Identification and Security — Regolith Explorer mission. Known in acronymic astro-speak as OSIRIS-REx, that seven-year-long voyage brought home the goods via a sample return canister that came to full stop … Read more
A detailed investigation of asteroid Ryugu samples has provided further evidence that the organic molecules which gave rise to life to our planet were brought here by ancient comets. These space rock samples were returned to Earth by Japan’s Hayabusa2 mission, which visited the spinning-top-like space rock Ryugu in 2018. Hayabusa2 spent around 18 months … Read more
Later this year, the European Space Agency (ESA) will launch the Proba-3 mission into orbit around Earth. This unique project’s twin spacecraft will align with each other to create frequent, artificial eclipses in space, which will give researchers near-unlimited access to studying the sun’s outer atmosphere, or corona, for the first time. An upcoming terrestrial … Read more
A roughly 3,000-year-old stone disk covered with enigmatic markings is actually an ancient celestial map marking the brightest stars in the night sky, researchers claim. The tire-size stone, which was discovered near an ancient hill fort in northeastern Italy a few years ago, features 29 carved markings on its front and back that may represent … Read more
In the 1930s, a Swiss astronomer named Fritz Zwicky noticed that galaxies in a distant cluster were orbiting one another much faster than they should have been given the amount of visible mass they had. He proposed than an unseen substance, which he called dark matter, might be tugging gravitationally on these galaxies. Since then, … Read more
Astronomers have accidentally discovered the first known intergalactic trail of stars. The gigantic “stellar stream,” which is around 10 times longer than the Milky Way, suggests that more of these structures could be lurking in deep space, a new study reveals. Stellar streams are elongated threads of gravitationally entwined stars that have likely been ripped … Read more
The strength of solar storms hitting Earth can vary dramatically over short distances, with places just a few dozen miles apart experiencing very different magnetic disruptions, new research finds. This could mean that some areas are more vulnerable to large solar storms than previously appreciated, study co-author Eija Tanskanen, the director of the Sodankylä Geophysical … Read more
