Answers

A1. Hydrogen

Hydrogen fusion in the Sun's core produces the energy that powers its luminosity, and it has been the primary fuel since the Sun's formation around 4.6 billion years ago.

A2. 243 Earth days

Because Venus takes about 243 Earth days to complete one full rotation on its axis, which defines the length of a day on the planet.

A3. Blue

Because the atmosphere on Mars is much thinner than on Earth, allowing more blue light to scatter, making the sun appear bluer when viewed from there.

A4. Europa

Because it has a subsurface ocean beneath its icy crust, providing the potential for conditions suitable for life.

A5. Barred spiral galaxy

Because our galaxy has a central bar-shaped structure of stars and features spiral arms extending from it, distinguishing it as a barred spiral type.

A6. Nitrogen and methane

Titan's dense atmosphere is mainly nitrogen with significant methane, which contributes to the moon's methane rain and hydrocarbon lakes.

A7. Yuri Gagarin

Because Yuri Gagarin was the first human to complete a successful orbit of Earth.

A8. A galaxy of nougat!

The Milky Way contains over 200 billion stars and spans about 100,000 light-years across, making it a vast galaxy with a complex mix of stellar populations and cosmic dust.
