A 'Blood Moon' typically occurs during which event?
Correct Answer: B. Total Lunar Eclipse
A Blood Moon occurs during a Total Lunar Eclipse. The Earth's atmosphere scatters sunlight and projects reddish light onto the Moon. This gives the Moon a copper or red color.
The shape of the Earth is best described as?
Correct Answer: C. Geoid (Oblate Spheroid)
The shape of the Earth is described as a Geoid or Oblate Spheroid. It is slightly flattened at the poles and bulges at the equator. This is due to the centrifugal force of its rotation.
Which moon is believed to have a subsurface ocean of liquid water beneath an icy crust?
Correct Answer: C. Europa
Europa, a moon of Jupiter, is believed to have a vast subsurface ocean. This ocean exists beneath a thick crust of ice. It is considered one of the most likely places to find extraterrestrial life.
What happens during a 'Neap Tide'?
Correct Answer: C. Difference between high and low tide is minimum
During a Neap Tide, the difference between high and low tides is at its minimum. This occurs when the Sun and Moon are at right angles to each other relative to Earth. It happens during the quarter moon phases.
The 'Andromeda Galaxy' is the nearest major galaxy to the Milky Way. What type of galaxy is it?
Correct Answer: D. Spiral
The Andromeda Galaxy is a Spiral galaxy, similar to the Milky Way. It is the largest galaxy in our Local Group. It is on a collision course with the Milky Way.
The term 'Syzygy' refers to?
Correct Answer: A. Alignment of Sun, Earth, and Moon
Syzygy refers to the straight-line alignment of three celestial bodies. In the context of Earth, it usually involves the Sun, Earth, and Moon. This alignment causes eclipses and Spring tides.
Which planet rotates on its axis the fastest?
Correct Answer: C. Jupiter
Jupiter has the fastest rotation speed of any planet. It completes one rotation in just under 10 hours. This rapid spin causes the planet to bulge at the equator.
What is the primary component of the atmosphere of Mars?
Correct Answer: C. Carbon Dioxide
The atmosphere of Mars is composed primarily of Carbon Dioxide (about 95%). It is very thin compared to Earth's atmosphere. This thin atmosphere cannot retain much heat.
The 'Event Horizon' is associated with which celestial phenomenon?
Correct Answer: D. Black Hole
The Event Horizon is associated with a Black Hole. It is the boundary beyond which nothing, not even light, can escape the gravitational pull. It is often called the 'point of no return'.
Which organization is responsible for naming celestial bodies?
Correct Answer: C. International Astronomical Union (IAU)
The International Astronomical Union (IAU) is responsible for naming celestial bodies. It was founded in 1919. It defines the official names of stars, planets, and other space objects.
