Titan: The Earth-Like Moon with Alien Seas

Image
 In my previous blog, I shared about Ganymede, the largest moon of our solar system.And here I am with the second largest moon, and the largest moon of Saturn - Titan, which is just 2% larger than Ganymede. A World Hidden in Haze Titan, a moon wrapped in where rivers flow,rains fall and seas glisten. I feels like Earth - until you realise those rivers and seas are not made of water, but liquid methane and ethane.Like Earth, Titan's atmosphere is mostly composed of nitrogen with traces of methane. It is also thought to have a subsurface ocean of water. Its surface, sculpted by wind and rain, shows dunes that stretch for thousands of kilometers,dunes made not of sand, but of dark hydrocarbon grains. There are mountains, valleys, and even evidence of cryovolcanoes, which may spew icy water instead of molten lava. Titan is not a frozen, dead world; it is active, evolving, and alive with strange processes. Titan passes in front of Saturn(Image credit:NASA) What We've Discovered? For...

Ganymede:The largest moon of the entire Solar System

Image
Ganymede, one of the largest moons of Jupiter, is the largest moon in the entire Solar System. Spacecraft images show that its surface is a mix of two types of terrain: 40% of the surface is covered by highly cratered dark regions, and the remaining 60% is covered by light-grooved terrain.   Image of the dark side of  Ganymede. Image credits: NASA Existence of Saltwater Ocean Scientists have strong evidence suggesting the existence of an underground saltwater ocean beneath Ganymede's surface, which may contain more water than all the water on Earth's surface. This ocean is estimated to be 60 miles (100 kilometers) thick, which is 10 times deeper than Earth's ocean. It is believed to be located beneath a 95-mile (150-kilometer) thick crust of mostly ice. Additionally, several mineral salts and organic compounds have been found on the surface. Possibility of an Oxygen Atmosphere Scientists also share the possibility of having a thin layer of oxygen on its surface. Daytime sur...

Europa-A Ocean World of our Solar System

Image
Europa, also known as Jupiter II is the smallest Galilean moons orbiting Jupiter. It is the sixth-largest moon of the solar system with radius 1560.8 kms. It was discovered more than 400 years ago by Galileo Galilei. Europa (Image credit:NASA) Water in Europa Scientists assume that a salty Ocean lies beneath Europa's icy crust. During a process known as tidal heating,Jupiter and it's moons stretch and squish each other enough to warm them.Thus,it maintains the liquid state of the ocean.Also,it creates melted pockets, or lakes,throughout the moon's outer shell. In 2014 and 2016,humble spotted possible water plumes erupting off the Europa's surface. This could be an excellent target for the upcoming Europa Clipper mission. Europa Clipper Mission  Europa Clipper Mission (previously known as Europa Multiple Flyby Mission) is an interplanetary mission. It has been planned for launch in 2024 to carry out a detailed survey of Jupiter's moon Europa and investigate whether i...

Venus May Have Supported Life Billions of Years Ago….

Image
Venus, the second planet from the sun also known as "Earth's twin" and the avatar of Parasu Rama. The Air pressure of the venus is 90 times greater than that on Earth. Temperatures are hot enough to melt lead. The atmosphere is composed of toxic carbon dioxide and sulphuric acid. In other words, like a hell…. Yet billions of years ago, things were different on the planet. Venus resembled similar to our planet: liquid water oceans, white fluffy clouds, a place for life to potentially call home. In 1978, NASA's Pioneer Venus spacecraft found evidence that the planet may have once had shallow oceans on its surface.  An artist's representation of the planet Venus with water on its surface. (Image credit: NASA) How did venus change from an "Earth-like" planet to the hot, hellish place it is today? Billions of years ago, our sun was smaller and dimmer, and Venus was perfectly fine, chilling out. But as the sun aged it got brighter and hotter. Venus started t...
