A new 20-year NASA timelapse taken from space shows in just a few minutes how life on Earth shapes the planet year by year.

Several satellites were used between September 1997 and September of this year, to compile the data. However, there are indices provided to judge the post and understand what is the exact state of biosphere on planet Earth.

Werdell said the visualization shows spring coming earlier and autumn lasting longer in the Northern Hemisphere. On the other hand, a fleet of Earth-observing satellites tracked the spread of the newly green vegetation.

Employee of the jet propulsion laboratory of NASA renyu Hu said that on one of the exoplanets in the star system 55 Cancer can be the atmosphere, its composition and characteristics similar to earth.

Mill said he was badly beaten by police when they arrested him in 2008 and used a bloodied mugshot of himself as the cover of his "DC4" mixtape.

The new video reveals in startling detail the changes our land and oceans have experienced over the past two decades.

Using data gleaned from observations of rising sea surface temperatures, NASA researchers have been able to show that phytoplankton growth is becoming increasingly impeded, indicating that less carbon dioxide - the greenhouse gas most responsible for runaway climate change - is being absorbed by the microorganisms.

As per NASA, these discoveries point to important questions about how ecosystems will respond to the change in climate and changes in human interaction with the land. The changes in temperature have resulted in more green matter in the Arctic; the shrubs have extended beyond their typical range as areas become warmer than they were in past years. Though NASA is known primarily for its space missions, the agency focuses extensively on Earth science, too, training a variety of satellites down toward our own planet. However, cutting-edge satellite technology is capable of tracking subtle changes on both land and ocean's surface and allows scientists to routinely analyze consequences.
