Takeaways

• 😀 Uranus has a day that lasts 17 hours, 14 minutes, and 24 seconds, but due to its tilt, its year lasts 21 Earth years.
• 😀 A star named Lusi, located 50 light-years from Earth, is essentially the largest diamond ever discovered in space, made almost entirely of carbon.
• 😀 Neutron stars are the densest objects in the universe, with gravity 2 billion times stronger than Earth's.
• 😀 Sound cannot travel in space because it requires a medium (air or molecules) to vibrate, and space is a vacuum.
• 😀 Kelt-13b is the hottest planet known, with temperatures reaching 4,300°C due to its proximity to its massive star.
• 😀 Mars' moon Phobos will eventually be torn apart by gravitational forces, potentially forming a ring around the planet in 30-50 million years.
• 😀 The rings of Saturn were formed gradually and are categorized alphabetically based on the order of their discovery.
• 😀 The Sun, a yellow dwarf star, is halfway through its life cycle and will eventually become a red giant, swallowing Mercury, Venus, and Earth before shrinking into a white dwarf.
• 😀 The lack of gravity in space can cause astronauts' spines to stretch by up to 3%, but this is temporary when they return to Earth.
• 😀 The Moon’s surface is uneven, with one side having more mountains due to Earth’s gravitational influence, making it thinner on the side visible from Earth.

Q & A

What is unique about the planet Uranus and its rotation?

Uranus has an unusual rotation as its axis is tilted by about 98°. This causes one day on Uranus to last 17 hours, 14 minutes, and 24 seconds, while a year on Uranus equals 21 Earth years.

What is significant about the star Lusi?

Lusi is considered the largest diamond ever discovered. It is a star located 50 light-years away, and its core is made of crystallized carbon, making it an extraordinary object in space.

What are neutron stars, and why are they important in space studies?

Neutron stars are incredibly dense remnants of massive stars. Despite their small size, about the size of a small city, their mass is 1.5 times that of our Sun. The gravity on these stars is two billion times stronger than Earth's.

Why can’t we hear sound in space?

Space is a vacuum, meaning there are no air molecules to transmit sound waves. Hence, sound cannot travel through space, making it impossible to hear anything in the vast expanse between stars and planets.

What is the planet Kelvin b known for?

Kelvin b is the hottest known planet, with temperatures reaching up to 4300°C. Its extreme heat is due to its proximity to its star, Kelt Main, which is much hotter and larger than our Sun.

What is Mars' unique feature regarding its moons?

Mars has two moons, Phobos and Deimos. However, in 30-50 million years, the gravitational pull of Mars is expected to destroy Phobos, potentially forming a ring around Mars.

How does the Sun impact the Earth's atmosphere and life?

The Sun's winds, known as solar winds, interact with Earth's atmosphere, causing phenomena like auroras. The Sun's energy is also crucial for sustaining life on Earth.

What happens to astronauts' bodies in space?

In the low gravity of space, astronauts' bodies can grow up to 3% taller due to the stretching of their spines. However, this effect is temporary, and their bodies return to normal once they are back on Earth.

Why does the Moon always show the same side to Earth?

The Moon always shows the same side to Earth because it rotates at the same speed as it orbits Earth, meaning one rotation takes as long as one orbit around our planet.

What is the significance of the space debris surrounding Earth?

There are over 500,000 pieces of space debris, including rocket parts and dead satellites, orbiting Earth at speeds of 28,000 kilometers per hour. This poses a risk to spacecraft and satellites.
