An object with the appearance of a "new star" was discovered on Wednesday from Japan remains vigilant observers and astronomers around the world with reports that his brilliance continues to increase and has been spotted without the aid of telescopes. Although many think that it is a "supernova", ie the explosion of a star much more massive than the Sun, it is another type of stellar explosion known as "nova," the Astronomical Society of the Caribbean (SAC) . Koichi Itagaki, Japanese amateur astronomer noticed a "bright star" which did not appear in images captured the day before. Subsequent observations made from other parts of the planet that confirmed that this is a nova. The SAC said the blast was captured by several astrophotographers from Puerto Rico. The organization explained that a nova occurs in binary stars (double) when a star is a normal and our Sun, while its companion is a "white dwarf". Scientists have observed that in this type of stellar pairs, the proximity between the two stars causes the white dwarf to obtain or "stealing" gas from the normal star, when hydrogen is closer to the surface of the white dwarf, the gases reach such high temperatures that literally an explosion occurs. "In this type of event that explodes is the gas cloud that approached the white dwarf and the star itself," added the college. Astronomers have analyzed the light of the nova and calculated that the ejected gas explosion at a speed of 4.5 million miles per hour. The explosion has been called "Nova Delfini 2013", as this is visible in the constellation Delphinus (the Dolphin). Continues to increase its brilliance Observations from different parts of the world suggest that the "Nova Delfini 2013" continues to increase its brilliance and some sky enthusiasts have indicated that from places without light pollution, the nova is beginning to be visible without the aid of binoculars or telescopes. She is portrayed from Puerto Rico The organization has attracted hundreds of spectacular astronomical images from the Island explained that through binoculars, the new nova looks very similar to a "bright star", but said that at least from urban Puerto Rico, is not yet visible eye due to excess existing lighting. Juan Gonzalez Alicea, one of the SAC astrophotographers, captured an image of the explosion in the sky from his home in Peñuelas. Look at the photo:
