Newfound tiny planet may be a glimpse of Earth’s ultimate fate!

In 1995, a cosmic question was answered from a ground based telescope. Astronomers found a faint signal hundreds of light years away. The telescope found an exoplanet orbiting a star in our galaxy. Exoplanets are worlds that exist outside of our solar system. These celestial bodies usually orbit their own stars. There are 4 classifications of exoplanets: Neptune-Like, Hot Jupiter, Super Earth, and Earth Analog. There is a method called spectroscopy with which the light from the star is analyzed with a special machine. Astrophysicists confirmed the presence of nearly 4,000 exoplanets in the Milky Way. A group of researchers has zeroed in on a planetary body closely orbiting a white dwarf. A white dwarf is a burned out star that’s on it’s death door. Scientists think that our sun will become a white dwarf in billions of years.

A big reason why humans study exoplanets is so we can learn more about the evolution of our own solar system. In addition, exoplanets may hold life and possibly be habitable. When a star is dying it expands, and the gravity rips apart everything near it which causes disks of debris. Scientists assume Earth will face the same fate. But there is a tiny bright; side if two exoplanets were to collide they could make a new stable planet. Maybe the planet could be habitable. I picked this article because I love space and new discoveries about it. I think it is important to know about; exoplanets they may contain extraterrestrial life.
