Hidden magma oceans could shield rocky exoplanets from harmful radiation

Deep beneath the surface of distant exoplanets known as super-Earths, oceans of molten rock may be doing something extraordinary: powering magnetic fields strong enough to shield entire planets from dangerous cosmic radiation ...

Two new exoplanets and the need for new habitable zone definitions

At the beginning of the exoplanet age, the goals were fairly simple. The first was to find as many of them as possible to flesh out our understanding of the exoplanet population. The second was to determine if any were in ...

NASA's Pandora telescope will study stars in detail to learn about the exoplanets orbiting them

On Jan. 11, 2026, I watched anxiously at the tightly controlled Vandenberg Space Force Base in California as an awe-inspiring SpaceX Falcon 9 rocket carried NASA's new exoplanet telescope, Pandora, into orbit.

Pandora, a keen-eyed satellite built to study exoplanets, readies for launch

Pandora, the latest in a long portfolio of University of Arizona's space science missions, has cleared its last major milestone on its journey into space. This week, Pandora—a satellite about the size of fridge—was mounted ...

To understand exoplanet habitability, we need a better understanding of stellar flaring

One of the main questions in exoplanet science concerns M dwarfs (red dwarfs) and the habitability of exoplanets that orbit them. These stars are known for their prolific and energetic flaring, and that's a problem. M dwarfs ...

Solar flares and stellar flares hit differently

The sun is not only our closest stellar neighbor, it's also the star we understand the most. As we've observed it over the centuries, we've learned that the sun is not an immortal constant. It goes through active and quiet ...

Five new planets and the battle for their atmospheres

One of the primary goals of the James Webb Space Telescope (JWST) is to detect atmospheres around exoplanets, to try to suss out whether or not they could potentially support life. But, in order to do that, scientists have ...

Using bent light to map complex planetary architectures

With new technologies comes new discoveries. Or so Spider Man's Uncle Ben might have said if he was an astronomer. Or a scientist more generally—but in astronomy that saying is more true than many other disciplines, as many ...

Why most exoplanets are magma worlds

In astronomy, there is a concept called "degeneracy." It has nothing to do with delinquent people, but instead is used to describe data that could be interpreted multiple ways. In some cases, that interpretation is translated ...

The solution to finding an atmosphere on TRAPPIST-1 e

The hunt is on for terrestrial exoplanets in habitable zones, and some of the most promising candidates were discovered almost a decade ago about 40 light-years from Earth. The TRAPPIST-1 system contains seven terrestrial ...
