Strange Solar Gamma Rays Discovered at Even Higher Energies
There appear to be too many gamma rays coming from the sun. New higher-energy measurements reveal that this excess continues for a bit, then disappears — a cutoff that could help clarify what’s going on.
Sun’s Puzzling Plasma Recreated in a Laboratory
For the first time, researchers have created a scale model of the twisting loops of the sun’s magnetic field.
The Sun Is Stranger Than Astrophysicists Imagined
The sun radiates far more high-frequency light than expected, raising questions about unknown features of the sun’s magnetic field and the possibility of even more exotic physics.
Planets Found to Be Larger Than the Disks They Come From
The new finding is challenging established theories of how planets come to be.
What Is the Sun Made Of and When Will It Die?
If and when physicists are able to pin down the metal content of the sun, that number could upend much of what we thought we knew about the evolution and life span of stars.
Eclipse Hunter Reveals the Science That Can Only Be Done in the Dark
Even in the age of sun-observing satellites, astronomers like Jay Pasachoff still seek out total solar eclipses for the tales they can tell about our sun.
