Asteroid Vesta is like a giant anthill- VIDEO

Wednesday, 31 October 2012 22:11


In the magazine Nature, a team of astronomers, led by Thomas McCord from the Bear Fight Institute in Winthrop, USA, Carle Pieters from Brown University in Providence, USA and Christopher Russell from the University of California at Los Angeles, United States published an article, which is stated that the asteroid Vesta covered with a layer of small stones up to 2 meters thick. This explains the phenomenon of absence on the surface of the asteroid Vesta, signs of damage to its surface rocks from the solar wind, which was discovered by automatic station «Dawn». As reported these U.S. planetary scientists, over past 3.5 billion years, on the surface of the asteroid Vesta fell about 300 large asteroids with a diameter of 1 km to 10 km, and the rocks from which they are composed, with the impact smashed into little stones, that covered the surface of the asteroid Vesta as a layer of crumbs in the form of a giant blanket, up to 2 meters thick in some places, making the asteroid Vesta is like a giant anthill, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... vesta.html

The asteroid belt is a necessary condition for the emergence of life- VIDEO

Friday, 02 November 2012 14:10


In the magazine Monthly Notices of the Royal Astronomical Society: Letters appeared an article of group of scientists from the University of Colorado at Boulder and from STScI of Hubble in Baltimore, under the direction of Rebecca Martin and Mario Livio, where argued, that the width and location of the asteroid belt in the system of planets may be necessary and determining factor in the emergence and development a complex life forms on the planets of this systems. As also reported by the press service of NASA, the periodic collisions with asteroids can accelerate the evolution of complex forms of life, causing them to quickly adapt to changing environmental conditions. As reported Rebecca Martin and Mario Livio, only a very small number of known planetary systems have conditions, which could contribute to the emergence of complex life forms in the same way as it does on Earth, where the attraction of Jupiter made it impossible to form a new planet, but formed the asteroid belt, which perfectly fulfills the conditions, which are necessary for life on Earth, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... -belt.html

Dwarf planet Makemake has not of atmosphere- VIDEO

Thursday, 22 November 2012 12:10


In the Nature magazine was published an article of a group of scientists from the Institute of Astrophysics of Andalusia in Granada, Spain, under the leadership of Jose Ortiz, about the fact, that the radiation from a distant star NOMAD 1181-0235723, which took place against the background of a dwarf planet Makemake, helped to the Spanish astronomers found, that a dwarf planet Makemake has no atmosphere. Previously it was thought, that the atmosphere on the dwarf planet Makemake must be present, but, as reported by Jose Ortiz, the first new data about the properties of the planet Makemake refuted the expectations of scientists. Makemake dwarf planet discovered in 2005 by American astronomer Michael Brown, naming it in honor of the god of abundance Mac-make of the inhabitants of Easter Island mythology, Makemake is a large rocky body with a diameter of 1,400 km, the planet is located from the Sun at a distance 52 times farther, than the Earth. Study of the dwarf planet Makemake by group of scientists from the Astrophysical Institute of Andalusia in Granada were performed using a 16 ground-based telescopes, including the VLT, NTT and TRAPPIST, which are located in the La Silla observatory and Paranal in Chile, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... emake.html

NASA for the first time conducted a series of radar observations of asteroid 2007 PA8- VIDEO

Tuesday, 27 November 2012 14:01


Space agency NASA reported, that NASA scientists, using of the 70-meter radio telescope in Goldstone, California, USA, for the first time held a series of radar observations of asteroid 2007 PA8 during its last in the 21st century approach to the Earth. As reported, obtained data allowed to NASA scientists to accurately measure the orbit of the asteroid 2007 PA8 and even explore the details of its surface and more accurately calculate the period of rotation for the next 632 years. asteroid 2007 PA8 was opened at August 9, 2007 by LINEAR (Lincoln Near Earth asteroid Research), the size of the asteroid 2007 PA8 is 1.6-kilometers. As reported by NASA scientists, the resolution of the best images of asteroid 2007 PA8 was about 3.75 meters per pixel, which allowed to detect a craters, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... 7-pa8.html

NASA reported, that on 12 December 2012 at 06.40 GMT (10.40 Moscow time) Tautatis asteroid will fly near the Earth at a distance of 0.046 astronomical units (6.93 million kilometers) and on December 13, 2012 a Chinese vehicle "Chang'e-2" fly by at a distance of several hundred kilometers from the asteroid Tautatis and for the first time make pictures of the asteroid with a resolution of tens of meters. Tautatis asteroid (4179 Toutatis or 1989 AC) was opened in January 1989, the French astronomer Christian Pollas, Tautatis asteroid belongs to the group of potentially dangerous asteroids, but until 2196 the asteroid will not come close to the Earth closer, than 0.0198 astronomical units- 2.96 million kilometers. Form asteroid is wrong and elongate with 5.4 kilometers long, THE VIDEO:

Dawn probe discovered a river channels on the asteroid Vesta- VIDEO

Saturday, 08 December 2012 17:13


As reported the press service of the Jet Propulsion Laboratory of NASA, on the asteroid Vesta were discovered a mysterious channels, that are similar to river channels. According to Jennifer Scully from the University of California at Los Angeles, U.S., who led the team of scientists, which were decoding of pictures, that were taken by the probe Dawn, such channels, that we see on the Vesta- are not the usual examples of the following streams of dry material such as sand, which are observed on the Moon, but on the Vesta these sinuous channels are very similar to river beds, which left a flowing liquid, so how on Earth such similar channels, such as the Meteor Crater in Arizona, created by streams of liquid water. Scientists have not yet established the cause of formation of meandering channels on the asteroid Vesta, it is assumed, that these can be lava flows or traces of carbon dioxide, but did not receive signs of volcanic activity on the Vesta, so the true cause of these river beds on the asteroid Vesta must to be established, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... vesta.html

Asteroid 2014 KH39 from 3 to June 4, 2014 will fly at a distance of 438,480 km from Earth- VIDEO
Tuesday, 03 June 2014 23:59
In the night from Tuesday to Wednesday, at about midnight, the asteroid 2014 KH39 will fly to Earth at a distance of 438,480 kilometers, which is the distance in 1.14 times larger than the Earth-Moon distance. It will pass through the constellation Cepheus at a speed of about 11 km / sec, at the time of closest approach to Earth, it will be near the constellation Ursa Minor. Ideal conditions for observing this event will be in central Europe and Africa, but the brightness of the asteroid - 17, too small that it can be seen with amateur telescopes. Project virtual Telescope Project, under the leadership of Astrophysics Gianluca Masi, while convergence will provide pictures and comments in real time. 2014 KH39 was opened May 24 by automated project Mt. Lemmon Sky Survey. Further observations with this telescope and other apparatus, such as the Pan-starRS 1, set in Hawaii, helped determine its orbit and diameter - about 22 meters. Following the 2014 KH39, just five days, is relatively close to Earth will fly another 2014 HQ124 - at a distance of 3.3 times larger than the Earth-Moon distance . However, since the diameter of the asteroid - about 650 m, the brightness reaches the value +13.7. Observers from the Southern Hemisphere will be able to see it in 8 -inch telescopes and telescopes larger diameter at the time of passing through the constellation clock (Horologium) and Eridan (Eridanus), VIDEO:
