Is it enough for a planet to be in a habitable zone for life to exist? Any planet standing there would have to receive strong radiation from its parent star. It will eventually melt the planet’s atmosphere. (But the thick clouds on Venus reflect solar radiation, which is why they shine). The movement of molten…
Galaxies can be classified into three main types: elliptical, spiral, and irregular. Hubble’s morphological classification is a more detailed taxonomic method. Since the Hubble method classifies galaxies only on the basis of shape, it ignores the rate of star formation in Starburst galaxies and the number of active galaxies. Elliptical. (Elliptical galaxy) The Hubble taxonomy…
The age of the earth is 454 crore years. During this time, the earth has undergone unimaginable changes. Many times the earth shone on its face. For example, 300 million years ago, there were no oceans on earth today, only oceans. And a single continent. At that time, there was only the super continent of…
Astronomers studying celestial objects such as planets have revealed eight classifications based on mass systems. Billions of objects have been discovered in space, and astronomers make such discoveries every year. Planets are some of the most common celestial objects, and the most studied. Astronomers have come up with various classifications used to classify the planets….
For centuries, people have looked up at the night sky and wondered about what they see and beyond. Over time, with the development of the study of space and astronomy, scientists slowly began to answer these questions, naming different objects in space and predicting certain astronomical events. For those unfamiliar with the study of astronomy,…
Satellites are launched into space to perform a specific mission, and are specially designed to perform the required function. A satellite is a man-made object that is placed in orbit to fulfill a specific mission. Also known as man-made artificial satellites, they are different from natural moons, such as the moon. Different moons are classified…

Two years ago, on April 20, 2019, scientists received a unique radio signal from Alpha Centauri, 4 light years away from us. After much study, scientists arrived on December 20, 2020, concluding that it was more likely to be an alien signal. There are many valid reasons to come to such a conclusion. One of…
The heart of the world’s tallest creature, the giraffe, has many features. The giraffe’s neck is up to 6 feet high. This means that the brain is located at a height above the body. Pumping blood to the brain, which is located at such a height, is a laborious task. That is, it must pump…
Fossils trapped for over 50 million years in the pastry-puff rock formation – technically known as flysch – along a 13-kilometer stretch of land on the western coast of Gipuzkoa have earned this place a spot in the European Geoparks Networks. Like a book written in stone, each stratum of flysch contains a 60-million-year-old chapter…
