Reflection Paper

I always keep wondering what if there are some humans like us in other planets. It may possibly be true. If there’s an earth-like there must possibly a human-like. What if the there’s an aliens in the other planets? Is there a human in another planet? Many questions bear to my mind after watching that video. In this video segment adapted from NOVA, learn about the hunt for Earth like planets outside our solar system that may harbour life. Astronomer Geoff Marcy explains the challenges of finding infinitesimally small planets orbiting huge, very bright stars. By monitoring the light from distant stars, sensitive instruments can detect the very slight dimming that occurs when objects, such as orbiting planets, in front of them. The video also introduces us to NASA’s Kepler space telescope, launched in 2009 to discover Earth-sized planets and determine how many of the billions of stars in our galaxy have such planets. The video features real satellite imagery as well as simulations. In the race to find another Earth, scientists have just hit a major milestone. In a NASA teleconference yesterday, a team of astronomers announced that they’ve discovered a planet in a far-away solar system that’s the most Earth-like yet—almost certainly rocky, and at the right temperature for oceans of liquid. As the day goes by, the scientist discovers a lot of many things from the universe. How does it look like 500 years from now? What are those things that they might discover sooner or later? How does it feel to live to the other planets? And so on and so forth.
