Which celestial object is a remnant of a massive star that has undergone a supernova explosion?

  1. Black Hole

  2. Neutron Star

  3. White Dwarf

  4. Supernova


Correct Option: A
Explanation:

A black hole is the collapsed core of a massive star that has undergone a supernova explosion. It possesses immense gravitational pull, causing spacetime to curve and preventing anything, including light, from escaping.

  2. Sirius

  3. Alpha Centauri

  4. Vega


Correct Option: A
Explanation:

Proxima Centauri, a red dwarf star, is the closest star to our solar system, located approximately 4.2 light-years away.

Which astronomical phenomenon occurs when a star explodes, releasing enormous amounts of energy and matter?

  1. Supernova

  2. Black Hole Formation

  3. Neutron Star Collision

  4. Solar Flare


Correct Option: A
Explanation:

A supernova is a powerful explosion that occurs when a massive star reaches the end of its life. It releases vast amounts of energy and matter, including heavy elements like gold and uranium.

What is the name of the cosmic microwave background radiation, a remnant of the early universe?

  1. Big Bang Echo

  2. Cosmic Microwave Background

  3. Dark Energy Radiation

  4. Galactic Radiation


Correct Option: B
Explanation:

The cosmic microwave background radiation is the leftover radiation from the Big Bang, the event that is believed to have created the universe. It provides valuable insights into the early moments of the universe's existence.

Which celestial body is known for its distinctive red spot, a giant storm that has been raging for centuries?

  1. Jupiter

  2. Saturn

  3. Mars

  4. Venus


Correct Option: A
Explanation:

Jupiter, the fifth planet from the Sun, is famous for its Great Red Spot, a colossal storm that has been observed for over 300 years.

What is the name of the dwarf planet that was once considered the ninth planet of our solar system?

  1. Pluto

  2. Eris

  3. Haumea

  4. Makemake


Correct Option: A
Explanation:

Pluto, once classified as the ninth planet, was reclassified as a dwarf planet in 2006 due to its unique orbital characteristics.

  1. Galaxy

  2. Star Cluster

  3. Nebula

  4. Black Hole


Correct Option: A
Explanation:

A galaxy is a vast collection of stars, gas, and dust bound together by gravity. Our solar system resides in the Milky Way Galaxy.

What is the name of the largest planet in our solar system?

  1. Jupiter

  2. Saturn

  3. Uranus

  4. Neptune


Correct Option: A
Explanation:

Jupiter, the fifth planet from the Sun, is the largest planet in our solar system, both in terms of mass and volume.

Which astronomical phenomenon occurs when a star collapses under its own gravity, creating a dense remnant?

  1. Supernova

  2. Black Hole Formation

  3. Neutron Star Collision

  4. Solar Flare


Correct Option: B
Explanation:

Black hole formation occurs when a massive star collapses under its own gravity, creating a region of spacetime where gravity is so strong that nothing, not even light, can escape.
