     On the surface of planets discovered by Clyde Tombaugh in 1930, it seems an area that resembles a "heart shape".

Heart-shaped area on Pluto

     Pluto which usually can be seen as a point of light, then we can see the picture as a 'close-up - closer - like today after the efforts of NASA for 9 years. 3 billion mile journey to the New Horizon spacecraft.

     Although the discovery of 'heart shape' is already making hearts vibrate because of amazement, the scientists behind the New Horizons said, "The best do not even arise."

     Tuesday, July 21 next week, the spacecraft was scheduled to be approaching the planet Pluto with the closest distance than ever achieved before. Thus, NASA hopes to get a clearer picture of Pluto and much more detailed than the picture they ever took.

     "Next, we will see Pluto from the closest distance, so most of the region to be imaged at a resolution of approximately 500 times better than what we see today," said Jeff Moore, a geologist, geophysicist and a leader of the imaging team at NASA Ames Research Center, in a press release.

Cities at Night: The World Project for Conscientious Light Pollution

     Speaking of pollution, we often just assume pollution pollution of air, water or soil. Actually there is one form of pollution that often we have neglected the light pollution. To follow up on the pollution level, various organizations, including NASA and ESA, join and create a project called "Cities at Night". The project aims to examine the level of light pollution in many cities in the world and examines the impact.

     The project "Cities at Night" involving astronauts and International Space Station (ISS) to take pictures and data on pollution in many cities in the world directly from space. From the data collected to date, there are some facts that quite surprising. The light emitted by a large class of mega cities, it still can be detected up to tens or even hundreds of kilometers from the city area. In addition, the researchers also found that several European countries are heavily indebted large enough turned out to have a high level of light pollution.

     The discovery certainly confirms that light pollution not only affects the environment, but also can be used as one parameter of economic conditions in a country or city.

     In certain circumstances, a fire can create a  dangerous tornado fire because it can spread the sparks.

     Craig Fluer, a firefighter in the US Forest Service, uploaded the records tornado occurrence of a fire in a fire in Idaho through Instagram.

     He explained that the twister rising until it reaches a height of about 30 meters. He said, "This criminal blew flames up to 30 meters into the air before passing forward, dropping debris and hot ash into our helmets."

     According to a report in National Geographic, the whirlwind of fire (firenado) is actually quite common, but rarely recorded. Tornado is similar to the incidence of 'dust hell', but different from the tornado (tornado) is bigger and powerful due to large rotation patterns that become hurricanes.

     'Dust hell' formed when the hot air near ground level soared rapidly through the low-pressure air bags cooler. When air is inflated, the air bend vertically and cause rotation.

     Warm air that comes from the base of the vortex then soar well thereby strengthening the rotation. In the event of a fire vortex, fire that first heating the air at the surface.

     Back to the events in Idaho, fires there had devoured an area of ​​more than 113 thousand hectares in southwest Idaho and southeast Oregon, and already there are dozens of wild horses that died. Cause of the fire itself has not been clear until now.
