Halley's comet appears evey

69 years
81 years

Correct Answer

A. 76 years

Explanation

Halley's Comet is a famous periodic comet that appears in the Earth's sky approximately every 76 years. It was first recorded in ancient times and has been observed throughout history. The comet's orbit takes it far into the outer solar system, and it only comes close enough to Earth for us to see it about once every 76 years. This long orbital period is due to the gravitational influences of the planets in our solar system.

Strange objects called ...............have huge black holes at their centres

Correct Answer
quasars

Explanation
Quasars are strange objects in the universe that have huge black holes at their centers. These black holes are incredibly massive and actively accrete surrounding matter, emitting a tremendous amount of energy in the process. This energy release makes quasars some of the brightest objects in the cosmos. They are believed to be powered by the intense gravitational forces exerted by the black holes, causing the surrounding material to heat up and emit radiation across the electromagnetic spectrum. Quasars are important objects for studying the early universe and understanding the nature of supermassive black holes.
