Sorry guys. I am a little busy these days. But stay tuned I will be back with a lots of amazing photos of cosmos. :)
Pluto in Enhanced Color : Pluto is more colorful than we can see. Color data and images of our Solar System’s most famous dwarf planet, taken by the robotic New Horizons spacecraft during its flyby in July, have been digitally combined to give an enhanced view of this ancient world sporting an unexpectedly young surface. The featured enhanced color image is not only esthetically pretty but scientifically useful, making surface regions of differing chemical composition visually distinct. For example, the light-colored heart-shaped Tombaugh Regio on the lower right is clearly shown here to be divisible into two regions that are geologically different, with the leftmost lobe Sputnik Planum also appearing unusually smooth. New Horizons now continues on beyond Pluto, will continue to beam back more images and data, and will soon be directed to change course so that it can fly past asteroid 2014 MU69 in 2019 January. via NASA

What are Perseid Meteors, and why should you be excited for them this year? Let us tell you!
The Perseid meteor shower is caused by debris from Comet Swift-Tuttle as it swings through the inner solar system and ejects a trail of dust and gravel along its orbit. When the Earth passes through the debris, specs of comet-stuff hit the atmosphere at 140,000 mph and disintegrate in flashes of light. Meteors from this comet are called Perseids because they seem to fly out of the constellation Perseus.
Last year, this meteor shower peaked during a bright “supermoon”, so visibility was reduced. Luckily, forecasters say the show could be especially awesome this year because the Moon is nearly new when the shower peaks on Aug. 12-13.
The best place to view the event is away from city lights around midnight. Under a clear, dark sky forecasters predict meteor rates as high as 100 per hour on peak night. So, get outside, look up and enjoy the show!
If your area has poor visibility on the peak night, we’ve got you covered! We’ll be hosting a live broadcast about the meteor shower from 10 p.m. EDT Wednesday, Aug. 12, to 2 a.m. Thursday, Aug. 13. In addition to footage from our live skycam, the program will highlight the science behind the Perseids, as well as our research related to meteors and comets. Tune in on NASA TV or our UStream Channel.
Cosmic lighthouse known as the Egg Nebula, which lies around 3000 light-years from Earth. The image, taken with the NASA/ESA Hubble Space Telescope, has captured a brief but dramatic phase in the life of a Sun-like star.

Today, August 19, is National Aviation Day! You might wonder why we’re celebrating National Aviation Day, let us tell you…
First, did you know that EVERY U.S. commercial aircraft and every U.S. air traffic control tower has NASA-developed technology on board? It’s true! Here at NASA, we’re invested in aeronautic research. Today’s air transportation system is an integral part of the U.S. and global economies.
It’s the primary mechanism for connecting countries across the world through moving people, as well as goods and services. You feel the impacts of aviation and the air transportation system everyday. Just about every product produced and purchased today has been touched by aviation in some way. Aircraft transport 17.7 billion tons of freight every year. While you may not have flown today, something you needed did.
Our aviation experts are dedicated to improving the design of airplanes so they’re more Earth friendly – less fuel use, lower pollution, less noise around airports. We also work with the Federal Aviation Administration to provide new tools to air traffic controllers for improving efficiency and reducing delays.
So, celebrate National Aviation Day with us! Spread Your Wings, take a photo, post it today and tag #SpreadYourWings and/or #NationalAviationDay. We may even pick your photo to highlight on our NASA web page!
I love space. I've been to space camp in Huntsville Alabama and I am planning on going every summer. I look forward to be an astronaut for nasa on the sls that is planned to be launched 2018. And the manned mission 2030. So yeah I won't let anything get in my way.
