A new study from MIT found that climate change will make space junk pile up—causing ripple effects across everything from weather tracking to broadband internet to national defense. A photo composite ...

The invisible forces erupting from our Sun create a chaotic environment extending far beyond what most people imagine. Space ...

Given the mounting number of objects in orbit, this is likely to be a more regular occurrence. It's costly in terms of damage ...

For decades, satellites passing over Earth's north and south poles have experienced a flow of ions from the upper atmosphere into space. Dubbed the 'polar wind', the source of this flow had eluded ...

Scientists using the James Webb telescope observed a distant exoplanet with an atmosphere of soot and diamonds, challenging ...

JWST observations of the ultra-hot super-Earth exoplanet TOI-561 b provide the strongest evidence to date for an atmosphere surrounding a rocky planet beyond our Solar System.

Our planet is massive, and the surrounding space is even more massive. Despite that, scientists say that the amount of space junk pollution around our planet could poison the upper atmosphere and have ...

Mars is blanketed by a thin, mostly carbon dioxide atmosphere — one that is far too thin to keep water from freezing or quickly evaporating. However, geological evidence has led scientists to conclude ...

The secret has been hiding in plain view for 40 years. But it took the insight of a veteran astronomer to pull it all together within a year, using observations of Saturn from NASA’s Hubble Space ...
