Understanding solar activity is relevant because the physical phenomena that cause it cannot be studied on Earth, and also because it allows us to predict space weather. Solar storms (coronal mass ejections) carry large amounts of charged particles that form auroras...

The Sun may seem like a static object, resting in the center of the Solar System while the planets orbit around it. But this is not the case. Our star is constantly undergoing processes of change that release large amounts of energy. In fact, the stability of its...

When we look up at the night sky with our eyes, almost all of the bright spots we see twinkling are stars in our galaxy, the Milky Way. If the night is dark, we can also see faint spots of light. These are the galaxies closest to our own, the Andromeda Galaxy and the...

Students perform an investigation to measure the strength of gravity on Earth, either by measuring the acceleration of a falling object or by using Newton meters to weigh masses. They learn investigative skills as well as Newton’s classic model of gravity. Then...
