Researchers have unearthed three of the universe’s most ancient stars, residing right within our galactic neighbourhood. Three stars circling the Milky Way’s halo came into existence 12 to 13 billion years ago. Situated in the Milky Way’s expansive “halo” — the encompassing cloud of stars encircling the primary galactic disk — these stars were identified…
The new planet, named WASP-193b, appears to dwarf Jupiter in size, yet it is a fraction of its density. Image Credit: K. Ivanov Astronomers have uncovered a remarkable discovery in our Milky Way galaxy: a colossal, ethereal planet encircling a distant star. Detailed in the latest issue of Nature Astronomy, this finding offers a…
Researchers working with the Curiosity rover have discovered new evidence that there was a habitable environment on Mars billions of years ago. The study is published in the Journal of Geophysical Research: Planets. Curiosity discovered large amounts of manganese oxide in Gale Crater rocks that were once part of an ancient lake. This mineral is…
Illustration of an active quasar. New research shows AI can identify and classif… Artificial intelligence and machine learning have become ubiquitous, with applications ranging from data analysis, cybersecurity, pharmaceutical development, music composition, and artistic renderings. In recent years, large language models (LLMs) have also emerged, adding human interaction and writing to the long list of applications. This…
An asteroid dubbed “Lucy’s baby” after a NASA spacecraft discovered it is orbiting another asteroid last November is,, in fact,, a solar system toddler—just 2–3 million years old, a Cornell-led research team estimates using novel statistical calculations. The team derived the age of Selam, a “moonlet” circling the small asteroid Dinkinesh in the main asteroid belt between…
This magnetar is a highly magnetized neutron star. This artist’s illustration shows…. The Milky Way has a missing pulsar problem in its core. Astronomers have tried to explain this for years. One of the more interesting ideas comes from a team of astronomers in Europe and invokes dark matter, neutron stars, and primordial black holes…
This illustration provided by NASA depicts Voyager 1. The most distant spacecraft … NASA has finally heard back from Voyager 1 again in a way that makes sense. The most distant spacecraft from Earth stopped sending back understandable data last November. Flight controllers traced the blank communication to a bad computer chip and rearranged the…
