In Amiri’s calculations, Dyson spheres around white dwarfs tend to produce cooler, fainter thermal emission that peaks in the near- to mid-infrared, while M-dwarf cases can radiate more strongly but ...

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these ...

Stellar plasma can smear alien radio signals before they escape their star system, making them harder for astronomers to detect.
