scientists have suggested that the planet Kepler-62f might be habitable for life. If that’s so‚ it could open up a legion of other theories suggesting life exists on other systems surrounding Earth. Judging by NASA’s history with lying‚ they very well could have known about aliens for years. Let’s hope they’re not dangerous. POTENTIAL LIFE SURROUNDING EARTH A group of astronomers is suggesting that the planet called Kepler-62f may be habitable. The distant planet is approximately 1‚200 light-years

NASA has identified many planets outside our solar system. According to the article “Out of this world‚” the organization has discovered over twelve hundred thousand exoplanets throughout the Milky Way Galaxy. The TedX video “Are we Alone” explained that there are millions of planets in our universe. Astronomers discovered these planets by measuring the brightness of distant stars over time. Moreover they measured the brightness using advanced telescopes such as the Kepler. If the brightness fluctuates

It seems so natural to be myself these days‚ so I don’t regularly think about what I have been through to be who I am today. I am not certain of how many more mountains will take place in my life for me to climb‚ but I only know that I am ready to climb them because of the ups and downs I’ve climbed in the past.

Uranus Uranus Uranus is the seventh planet from the Sun and has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Though it is visible to the naked eye like the five classical planets‚ it was never recognized as a planet by ancient observers because of its dimness and slow orbit. It was the first planet to be discovered in modern history. It was discovered in 1781 by Sir William Herschel (Encyclopedia: Uranus (planet)) and expanded the known boundaries of

is‚ and the luminosity of Gliese 581 is .2 percent of the Sun’s luminosity. From this information‚ we know that Gliese 581 is a very dim star! There are three confirmed and two other possible planets that orbit Gliese 581. Each of these five planets are close to the star and have a circular orbit. The planets orbiting Gliese 581 were named in the order they were discovered and are named Gliese e‚ Gliese b‚ Gliese c‚ Gliese g‚ and Gliese d. The mass of Gliese 581e is 1.9 times the mass of Earth‚ Gliese

Universes ‚ I would first check to see if it’s a habitable planet. This planet should orbit a star that remains stable in output for billions of years. The star shoud provide brightness and warmth to the planet‚ be the energy source that lets plants make food to feed organisms. It is also important in that it will create seasons‚ weather patterns‚ oceanic currents and even sleep patterns for most living organisms. However‚ the planet should be a distance from the star that results in it achieving
