Man is a product of circumstances and environment. Hari Singh was just a boy of fifteen but was an experienced and fairly a successful hand. Circumstances made him a thief. In spite of being no use to Anil, he was retained to work for him. They say old habits die hard. After all, a thief couldn’t leave stealing and cheating. He made a rupee every day from the buying of the day’s supplies. However, Anil was not a fool. He knew everything and also all about the theft. But he was kind, large-hearted and full of human sympathy. He taught the unfortunate boy to write his name. Ile also promised him to write sentences and add numbers. This left a deep impression on the boy-thief. lie started realising that education could bring him respect and money.
Hari Singh breached Anil’s trust but Anil was all forgiving and compassionate. In the heat and excitement of theft, Hari Singh forgot about education. Then came the true realisation and transformation. The boy-thief realised that the only man who could help him was the man he had robbed a few hours ago. Then he realised the value of education that could give him respect and more money than he could get by stealing. He realised where he should go. Large-hearted Anil not only forgave him but also gave him a fifty-rupee note, and promised to pay him regularly.

Black holes are one of the strangest things in the Universe. They don’t seem to make any sense at all. It is an enormous amount of matter packed into a minimal area. To better understand, think of a star ten times more massive than the Sun packed into a sphere approximately the size of New York City.
There are four types of black holes as follows:
- Stellar
- Intermediate
- Supermassive
- Miniature

Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case, the Earth's shadow hides the Moon from view. A solar eclipse happens when the moon passes in between the earth and the sun. A lunar eclipse happens when the earth passes in between the moon and the sun. During a solar eclipse, the moon partially or fully hides the sun's rays for a few minutes.

- Solar eclipse: For a solar eclipse to occur the moon should be between the earth and the sun. Occurs once in 18 months
- Lunar eclipse: For a lunar eclipse to occur the earth should be between the sun and the moon. Occurs twice a year

Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or "star-forming regions", collapse and form stars.
- Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores.
- Aside from our Sun, stars appear as dots of light in the sky. Each and every one of them is light-years away from us and much brighter than our own star, the Sun.
- Stars are the building blocks of galaxies and in a sense life as we know it.
- Our galaxy the Milky Way contains an estimated 300 billion stars alone.
- Observations concluded that stars with high mass usually have shorter life spans. They nonetheless last for billions of years in general.
- Stars are usually birthed in hydrogen-based dust clouds called nebulae.
- Stars are classified by their spectra and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. This is known as the Morgan–Keenan (MK) system.
- The majority of all stars in our galaxy and even the Universe are main-sequence stars. Our Sun is a main-sequence star, and so are our nearest neighbors, Sirius and Alpha Centauri A.
- The majority of stars, at least until now observed, are typically red dwarf stars.
- Many stars come in pairs. They are binary stars that orbit a common barycenter.
- Stars have life cycles based on their initial mass.
- Stars do not twinkle. This is usually caused by Earth’s turbulent atmosphere instead.
- As far as the human eye can tell, there are no green stars. At least, we can’t perceive them.
- With the naked eye, we can perceive around 2.000 – 2.500 stars.

Stars are celestial objects that can produce their own light. They are extremely hot and extremely large. They are mostly made up of hydrogen gas with a little helium in them. The sun is also a star; the sun’s energy and light play one of the key roles in sustaining all forms of life on earth.
