Quiz Answer Key and Fun Facts

1. Which is the closest active galaxy to the Milky Way?

Answer: Centaurus A

Centaurus A is the nearest active galaxy to us. Its distance from earth is nearly 11 million light years. An active galaxy is a galaxy that has a highly luminous core and emits intense radiation.

2. Which of these stars has a surface temperature less than our sun's surface temperature?

Answer: Betelgeuse

Betelgeuse is a red supergaint star having a surface temperature of below 3500�C while surface temperature of our sun is 5500�C. All others are blue, hot stars.

3. Which is the brightest nebula in the night sky?

Answer: Orion

The Orion nebula is the brightest nebula in the night sky. Located in the sword of the constellation Orion, it is easily visible to the naked eye. It is a diffused nebula where new stars are born.

4. Name the black hole located in the center of our galaxy.

Answer: Sagittarius A

Sagittarius A is a supermassive black hole present in the center of our galaxy. This black hole has estimated to have a mass of 3 million solar masses. It is nearly 30000 light years away from us.

5. Which is the most distant object that a normal naked human eye can see in the night sky?

Answer: Andromeda galaxy

The Andromeda galaxy is the farthest object to be seen with naked eyes. It is nearly 2.2 million light years away from us. It is a spiral galaxy and also one of the closest galaxies in space.

6. The word Schwarzschild radius is related to which celestial body?

Answer: Black hole

The Schwarzschild radius, also known as event horizon, is the boundary of a black hole after which nothing even light can escape. A black hole whose mass is equal to sun has a Schwarzschild radius of 30 km.

7. Which type of celestial body is Gliese 229b?

Answer: Brown dwarf

Gliese 229a is a brown dwarf. This brown dwarf was discovered in 1995. A brown dwarf, also known as failed star, is a type of celestial body which is larger than Jupiter but not large enough to be a star because its core temperature doesn't is not high enough for nuclear fusion to take place and start releasing energy.

8. What type of nebula is the Horsehead Nebula?

Answer: Dark

The Horsehead Nebula is an example of dark head nebula. Dark nebulae are masses of obscuring matter that have no nearby star to illuminate them. Depending on their size, they can obscure quite a number of stars behind them.

9. Which celestial body has a super massive black hole in its center?

Answer: Quasars

Quasars are highly luminous radio galaxies and the most luminous objects in the universe. They are bright because in the center of every quasar, there is a supermassive black hole. Quasars are usually very far away from us: the nearest one is 13 billion light years away from our Earth, so it is difficult to study them.

10. Which star is also known as Zeta Orionis?

Answer: Alnitak

Alnitak or zeta orionis is the fifth brightest star in the constellation Orion. It is a blue supergiant star with an absolute magnitude of -5.25. It is about 800 light year away from Earth. It is also one of the star in Orion belt.
