If you are asked which planet is closest to Earth, then what would be your answer? Your common sense may say that it's Venus or Mars. And, you may be right theoretically. But, actually, you're answer is not entirely true. The answer is Mercury. Strange, isn't it!

Imagine a life outside the blue planet, Earth, where there is no sunrise, no sunset! Well, we cannot but astronomers have some different words to say. They believe that most of the planets in our galaxy that have Earth-like temperatures may be suitable for humanity. Because their orbital period is the same as their period of rotation, these planets will always present the same face to their sun, just like we see the moon as it orbits the Earth.

A recent space research claims that the mystery orbits of unknown in the outermost reaches of our solar system are not caused by the hypothesised ‘Planet Nine'. The phenomenon can be explained by the gravitational force of small bodies orbiting the Sun beyond Neptune.

While most scientists across the globe believe that oxygen plays a key role for the existence of life; a new study contradicts the age-old thinking. The study claims that presence of oxygen and organic compounds on planets don't necessarily mean they can host life.

In an attempt to search alien life outside the earth, astronomers have detected water in the atmosphere of a planet 179 light years away.

While China is known for designing artificial celestial bodies, its new artificial sun has become the talk of global town. It’s been a few weeks that we learnt that experts in the country was making a fake moon, now we came to know that it’s an earth-based sun simulator which is producing temperatures of 100 million degrees Celsius.

NASA's planet-hunting telescope has discovered two earth-like planets beyond our solar system. The orbital telescope has been launched five months ago from Cape Canaveral, Florida and within a short time it has come up with such a big discovery. Now that the earth-like planet has been discovered, the question uproots like if life is possible out there.

The reason Pluto lost its planet status is not valid and is erroneous, scientists argued challenging previously held theories.

The conditions for life on planets entirely covered in water are more fluid than previously thought, which opens up the possibility of water worlds being habitable, according to a new study.

NASA's Spitzer Space Telescope, the youngest member of the "Great Observatory" programme, has completed 15 years in space.
