Sirius, the brightest star in the night sky, is actually a binary star system. Sirius a is main-sequence star and sirius b is a white dwarf. Nearly all the visible light we see from sirius comes from sirius a. But when we photograph the system with x-ray light, as shown here, sirius b is the brighter of the two stars. Why?.

b would be the answer

pretty sure it's false

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
