NASA creates ultimate time-lapse of life on Earth

NASA creates ultimate time-lapse of life on Earth

Researchers claim that the atmosphere of this mysterious planet could contain nitrogen, water and even oxygen molecules that are found in our atmosphere, too. The density of the planet similar to ours, says renyu Hu, and has a rocky structure.

This fall marks 20 years since NASA has continuously observed not just the physical properties of our planet, but the one thing that makes Earth unique among the thousands of other worlds we've discovered: Life. It orbits its star so closely that it's tidally locked, meaning that the same side of the planet always faces its star.

However, due to the intense heat from its host star and its inability to maintain liquid water, the exoplanet doesn't have the potential to support life, the study said.

Dr. Del Geniois now leads a NASA interdisciplinary initiative to find alien life and understands his efforts will also involve rooting through the vastness of space to sort out the spots that might best host living things.

The "cold" side is still quite toasty by Earthly standards, with an average of 1,300 to 1,400 degrees Celsius, and the hot side averages 2,300 degrees Celsius. Isabel Angelo, first author of the study and a senior at the University of California, Berkeley, worked on the study as part of her internship at JPL and adapted Hu's model to 55 Cancri e.

Some scientists also believe that the planet's surface has flowing lava and its interior is filled with a large amount of diamonds.

After comparing the changes in brightness, the researchers realised an atmosphere with volatile materials could best explain the temperatures.

Called a "Super Earth" because it's roughly twice the size of our planet, 55 Cancri e is mighty hot.

Based on data from NASA's Spitzer telescope scientists previously speculated that the planet may be largely covered in lava.
