Consider the following statements about Sun Corona - 1. The Sun’s corona is the outermost part of the Sun’s atmosphere. 2. Corona can be viewed during a total solar eclipse Which of the above statements is/are correct? Correct Answer Both 1 and 2

The correct answer is Both 1 and 2.

In News

  • Scientists have recently discovered tiny flashes of radio light emanating from all over the Sun, which they say could help in explaining the long-pending coronal heating problem.
  • The data was collected with the help of the Murchison Widefield Array (MWA) radio telescope.
  • What is it?
    • The radio lights or signals under study result from beams of electrons accelerated in the aftermath of a magnetic explosion on the Sun.
    • These observations are the strongest evidence till date that the tiny magnetic explosions, originally referred to as ‘nanoflares’ by eminent American solar astrophysicist Eugene Parker.

Key Points

  • The Sun’s corona is the outermost part of the Sun’s atmosphere. Hence, Statement 1 is correct.
  • The corona is usually hidden by the bright light of the Sun's surface.
  • That makes it difficult to see without using special instruments. However, the corona can be viewed during a total solar eclipse. Hence, Statement 2 is correct.

The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.

The following sentences form a paragraph. The FIRST and SIXTH sentences of the paragraph are given. The rest of the sentences are numbered as B, C, D, ad E, which are not in proper order. Read the sentences and place them in chronological order. National Solar Mission is one of the eight missions set up of National Action Plan on Climate change (NAPCC) that was released on 30 June 2008. With this ambitious target, India will become one of the largest Green Energy producers in the world, surpassing several developed countries. Government stepped up India’s solar power capacity target under the Jawaharlal Nehru National Solar Mission (JNNSM), by five times, reaching 1,00,000 MW by 2022. The target will principally comprise 40 GW Rooftop and 60 GW through Large and Medium Scale Grid Connected Solar Power Projects. The new targets were approved in June 2015. During recent times with improvement in technology and scaling up production capacities, solar energy has become cost-competitive and targets seem to be more viable now.
In the following question, out of the four alternatives, select the alternative which will improve the underlined part of the sentence. In case no improvement is needed, select “No improvement”. When the Sun, the Moon, and the Earth are aligned in a straight line or an almost straightly configuration, such that the Moon comes between the Sun and Earth blocking the rays of Sun from directly reaching the Earth, we witness a solar eclipse.
