Earth can be a model for detecting vegetation on exoplanets
Back in December 1990, during its flyby of Earth, NASA’s Galileo spacecraft, which studied the planet Jupiter and its moons, as well as several other Solar System bodies, pointed its instruments towards Earth, at the urging of Carl Sagan. And, it has found evidence of life on our planet. This can be a key to detect vegetation on exoplanets – which is a key to a possible i
In a paper published on Nature, researchers wrote “The Galileo spacecraft found evidence of abundant gaseous oxygen, a widely distributed surface pigment with a sharp absorption edge in the red part of the visible spectrum, and atmospheric methane in extreme thermodynamic disequilibrium. Together, these are strongly suggestive of life on Earth.”

A cosmonaut’s view, just after launching a tiny satellite into the orbit
On August 15, 2018, two Russian cosmonauts aboard the International Space Station performed one of the longest spacewalks in the history of space exploration. During the spacewalk lasting 7 hours and 46 minutes, Expedition 56 Flight Engineers Sergey Prokopyev and Oleg Artemyev manually launched four small technology satellites and installed a German-led animal-tracking project named Icarus onto the Russian segment of the space station. Two of the satellites were only the size of tissue boxes.

Top 18 Largest Islands on Earth
An island or isle is any piece of sub-continental land that is surrounded by water. It is believed that there are over 100,000 islands in the world. It’s difficult to put a figure to the exact number as there are different kinds of them in various water bodies including oceans, seas, lakes, and rivers.
