What is the primary goal of the Gaia space observatory?

• To create a three-dimensional map of the Milky Way

• To find new galaxies beyond the Milky Way

• To study the atmosphere of Jupiter

• To explore the surface of Mars

How does Gaia determine the distance of stars?

• By comparing scans taken six months apart

• By observing their gravitational pull

• By analyzing their color

• By measuring their brightness

What causes the reddish-brown color at Charon's North Pole?

• Volcanic activity

• Tholins formed from cosmic radiation and UV rays

• Reflection of sunlight

• Presence of iron oxide

What is the relationship between Pluto and Charon's atmospheres?

• Charon has a thicker atmosphere than Pluto

• Pluto's atmosphere drifts to Charon and freezes

• Charon shares its atmosphere with Pluto

• Both have identical atmospheric compositions

What happened to the SpaceX Falcon 9 rocket on September 1st?
