Continuing our top 10 ranges, today we will write about top 10 largest cities in the world by land area.
Scientists have discovered a binary system of two dying stars, known as white dwarfs,which will be collide and birth to one new star. The newly identified binary system, designated SDSS J010657.39–100003.3, is located about 7,800 light-years away in the constellation Cetus, the Whale, and was discovered as part of a survey program conducted with the MMT Observatory on Mount Hopkins, Ariz.View More Dying stars will be reborn in one
According to director of the Institute of Astronomy RAS (INASAN) Boris Shustov, Solar system within its visible part detail “inventoried” and there are no unknown planets or other celestial bodies massive than the average asteroidView More Are there Unknown Bodies in the Solar System
In February on the Sun occurred the largest flare over the past 4 years.Things like that, known as X- class flare, they may even influence the communication on Earth.View More The Reason of X-Class Solar Flare
Tycho supernova, which is located about 13,000 light-years from Earth, formed when its parent star divided too much material from a nearby companion, forcing it to blow up in a massive thermonuclear explosion.View More Cause of the Explosion of Tycho Supernova
Asteroid 2010 SO16, discovered earlier telescope WISE, moves almost exactly on the Earth’s orbit and may be a “brother” of the Earth – one of a group of protoplanetary celestial bodies, from which it emerged, according to astronomers from the Northern Ireland Observatory Armag. Most asteroids near Earth (NEA), have very elongated orbits, SO16 but has a nearly circular orbit, and therefore can not converge to any other planet except Earth.Astronomers have decided to establish how stable the orbit of this asteroid, and how long it takes her.View More Astronomers Discovered the Asteroid with the Earth Like Orbit
After three flybys of Mercury over the last three years, the Messenger spacecraft is poised to settle into the first-ever orbit by a manmade object of the planet closest to the Sun.The goal of the mission is to provide scientists with data on Mercury unparalleled since the Mariner 10 spacecraft passed by three decades ago. And the more we understand about Mercury, NASA says, the more we’ll understand about how the other rocky planets in the solar system–Venus, Mars, and of course, Earth–formed and evolved.View More Earth Messenger Spacecraft Reaches Mercury Orbit
A University of Arizona engineering team led by Roger Angel has designed a new type of solar concentrator that uses half the area of solar (PV) cells used by other optical devices and delivers a light output/concentration that is over 1000 times more concentrated before it even hits the cells.View More Powerful Solar Telescope Developed by Arizona Engineering Team
