An illustration of the binary star system J0658 highlights its massive hot subdwarf primary star and a mysterious, unseen companion. The two stars orbit each other every 0.32 days. The companion might be a white dwarf, leading to a Type Ia supernova or a double white dwarf merger, or a neutron star, potentially forming a binary pulsar system. Further observations are required to uncover the companion's identity and the system's evolutionary path.
New data from the Perseverance rover challenges the "Cold & Icy" theory, suggesting ancient Mars was drenched in persistent heavy rainfall for millions of years.
Mars today is a frozen desert. But 4 billion years ago, during the Noachian Epoch, it was a very different world. Evidence of river valleys and lake beds is undeniable, but the climate that created them is hotly debated.
An interstellar comet is speeding out of our solar system at 60 km/s. We missed the chance to launch directly. But we can still catch it—by diving into the Sun.
3I/ATLAS is the third interstellar object (ISO) ever detected. Like 'Oumuamua and Borisov before it, it's a visitor from another star system.
We need satellites to save the Earth, but launching them endangers space itself. A new model helps designers balance vital data against the risk of collision.
Earth-observation satellites are critical for tracking climate change and disasters. But with 11,800 active satellites and predictions of 100,000 soon, Low Earth Orbit (LEO) is becoming a junkyard.
