What are solar storms and the solar wind? 3 astrophysicists explain how particles coming from the Sun interact with Earth

Space weather isn’t referring to rain clouds that float through the galaxy. Instead, it’s caused by massive explosions of particles that shoot out from the Sun.

How do astronomers know the age of the planets and stars?

Measuring the ages of planets and stars is tricky. An observational astrophysicist describes the subtle clues that provide good estimates for how old different space objects are.

Massive flare seen on the closest star to the solar system: What it means for chances of alien neighbors

Astronomers just measured the largest flare ever from Proxima Centauri, humanity’s closest neighboring star. These flares could be bad news for life trying to develop on a planet orbiting the star.
