What was Galileo famous for?

Galileo was a natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method. He also made revolutionary telescopic discoveries, including the four largest moons of Jupiter.

How did Galileo contribute to astronomy?

Galileo’s contributions to astronomy include manufacturing excellent telescopes for his time period, studying the moon, discovering four of Jupiter’s brightest moons, discovering that Venus goes through phases similar to the moon (which influenced astronomers to transition away from Aristotelian celestial physics), and …

Which country first found water on moon?


What is Moon made up of?

Under the surface. Like the Earth, the moon boasts a crust, mantle and core. Deep inside of its interior, the moon may have a solid iron core surrounded by a softer, somewhat molten liquid iron outer core. The outer core may extend as far out as 310 miles (500 km).

How many seas are on the moon?

The traditional nomenclature for the Moon also includes one oceanus (ocean), as well as features with the names lacus (lake), palus (marsh), and sinus (bay). The last three are smaller than maria, but have the same nature and characteristics.

Can the moon support life?

Potential for Life? The Moon’s weak atmosphere and its lack of liquid water cannot support life as we know it.

Can we breathe on the moon?

The Moon doesn’t have an atmosphere or air for humans to breathe. But its surface – which is covered by a substance called lunar regolith (Moon dust!) – is almost 50% oxygen.

What if the moon didn’t exist?

Without the moon, tides would be weaker, affecting the tidal ecosystems for which tidal mixing and flow are important sources of energy. But this seems more like a quantitative effect, not the huge qualitative effect we’d get from a much faster spin.

What if the Earth stopped spinning?

If the Earth were to stop spinning on its axis, gradually the oceans would migrate towards the poles from the equator. You could travel around the Earth on the equator and stay entirely on dry land—ignoring the freezing cold on the night side, and the searing heat on the day side.

Can the whole world see the moon?

A: No, everyone sees the same phases of the Moon. (People north and south of the equator do see the Moon’s current phase from different angles, though. If you traveled to the other hemisphere, the Moon would be in the same phase as it is at home, but it would appear upside down compared to what you’re used to!)

Is the moon upside down in Australia?

In Australia, the Moon is “upside down” from the point of view of northern hemisphere viewers. We see a jolly man’s face in the full moon, while their guy looks a bit alarmed. The dark and light patches on the Moon’s surface are reminders of its hectic past.

Is the moon upside down?

It’s upside down in the sky, relative to what you’d be used to in the Northern Hemisphere. Likewise, if you’re used to a Southern Hemisphere sky, moving to the Northern Hemisphere will turn the Moon upside down relative to what you’re used to.
