Very-long baseline interferometry (VLBI) is a technique in radio astronomy whereby multiple radio telescopes cooperate to bundle their received data and in effect create a much larger singular radio telescope. For this to work it is however essential to have exact timing and other relevant information to accurately match the signals from each individual radio
The solar system is home to many planets, meteors, satellites… and one asteroid that’s said to be worth an eyewatering amount. The Psyche asteroid was explored by a special spacecraft, and the reality may just blow your mind. First discovered in the 19th century, the huge mass of space matter has posed many questions for
Could humanity nuke an incoming asteroid to deflect it and save the Earth, disaster-movie style? A unique new impact simulation suggests that a nuclear option could be a viable last resort to avert an apocalypse. Researchers have recently found that space rocks can withstand much more stress than previously inferred from experiments and observations. Counter-intuitively,
The Green River’s dramatic route through Utah’s Uinta Mountains has puzzled geologists for more than a century. Now, a group of researchers from the United Kingdom and the United States claims to have identified the powerful subterranean force that pulled the river through the rock: a deep Earth process known as lithospheric dripping. Their findings
NASA’s Perseverance rover has completed its first-ever drive on Mars fully planned by artificial intelligence, the space agency announced. The demonstration, carried out on Dec. 8 and Dec. 10 of 2025, showed that generative AI could safely plan rover routes across Mars’ rugged terrain without manual input, automating a labor-intensive decision-making process typically performed by
The enormous storms of impenetrable clouds covering Jupiter’s surface make it nearly impossible for us to get a glimpse of what lies below. Any spacecraft attempting to get a closer look would be vaporized, melted, or crushed if it attempted to sail through. NASA’s Galileo spacecraft, for instance, went dark almost immediately when it intentionally
If humanity truly hopes to colonize the solar system, it must overcome a challenge arguably greater than any technological hurdle: human reproduction beyond Earth. The idea may sound like science fiction, but a group of experts says figuring out how to protect astronauts’ reproductive health—and even make babies in space—is a very real and urgent

After dark, look high in the east-southeast for a brilliant, steady point of light in Gemini — that’s Jupiter, shining at magnitude –2.6, brighter than any star in
Scientists have produced the most detailed map ever created of dark matter that runs throughout the Universe, revealing how it has influenced the formation of stars, galaxies, and planets. The research, which includes astronomers from Durham University in the UK, provides new insight into how this unseen substance helped draw ordinary matter together, forming galaxies
Should the weather be clear early on Tuesday morning, March 3, sky watchers across most of the Americas will have an opportunity to view one of nature’s most beautiful spectacles: A total eclipse of the moon. Unlike a total eclipse of the sun, which often requires a long journey to the path of totality, those
