The planet Venus, which is known as the ‘morning’ and the ‘evening’ star was named after the Roman goddess of love and beauty. Venus is sometimes referred to as Earth’s sister planet because they share some similarities. They are almost identical in size, mass, density, and volume. Also they are made out of the same nebula(a diffuse mass of interstellar dust and gas).
One of the most beautiful and also rare things that you will ever be able to see is the aurora. Anyone who has had the chance to see this wonderful site has been truly amazed and in awe. The Aurora is a bright glow that is observed in the night sky, usually in the polar zone. For this reason some scientists call it a “polar aurora” (or “aurora polaris”). In northern latitudes, it is known as the aurora borealis, which is named after the Roman goddess of the dawn, Aurora, and the Greek name for north wind, Boreas.
In 1705 Edmond Halley predicted, using Newton’s formulated laws of motion, that the comet, which was seen in 1531, 1607, and 1682 would return again in 1758. The comet did indeed return as predicted and was later named in his honor, even though he was not alive to see it himself. The average period of Halley’s orbit is 76 years but it is impossible to always calculate the dates of its reappearances by simply subtracting multiples of 76 years from 1986.
Nighttime clouds were detected for the first time on the planet known as Mars help to keep the planet’s surface warm after sunset when temperatures usually drop, a new study suggests. The nocturnal clouds are about five times thicker than their daytime counterparts and stay close to the ground, almost the way a fog does.
In 1666, Isaac Newton took the first step toward trying to understand visible light when he passed sunlight through a rainbow prism and watched it break into a kaleidoscope of colors. Just like the wavelength differences between various parts of the electromagnetic spectrum, the array of colors comprising visible light are made of waves that have different lengths between successive crests or troughs. Red waves are the longest and violet waves are the shortest.
