Astronomers first discovered asteroid aura surrounding structures
Astronomers around an asteroid discovered celestial aura structure, the nike tn requin small bodies located between Saturn and Uranus, about 250 km in diameter
Beijing March 27, according to the British Nature magazine website reported that astronomers around an asteroid discovered celestial halo structure, the small bodies located between Saturn and Uranus, about 250 kilometers in diameter. Fengyun small bodies called Chariklo
, Is by far the smallest was found to have the aura of celestial bodies in the solar system just before that of Jupiter, Saturn, Uranus and Neptune were confirmed to have the aura. Aura is interesting celestial phenomenon, because it is generally considered to be the formation of planets toms shoes and satellites . the first stage it will be very difficult to maintain stability in the gravitational field around the material to be very small celestial Brad Gary Booth said:. So we originally envisaged the existence of the halo structure and quality probably about the size of celestial bodies. So this time around a celestial body was found in the quality of even the existence of such a small halo, really very surprised.
Chariklo belongs to a class of groups is called Centaur-type ray ban outlet store asteroids in the outer solar system, its orbit is unstable such a small celestial bodies, and displays the dual characteristics of asteroids and comets. Since they are usually very small, very dim and distant, astronomical research for such challenging. Brad Gary Booth's group was when this little celestial observations cover a distant background stars between June michael kors-sac Then you wil 2013 3 DATE stumbled its aura.
In toms the occultation process, the researchers observed stellar brightness as anticipated weakening. However, they also noted that the brightness of two smaller amplitude decrease occurs before a occultation occurs after another in occultation occurs. When observations from all over South America, seven telescopes were pooled analysis, the study group concluded: these two luminance signal is attenuated by two very narrow halo caused by its width and sac michael kors soldes 3 respectively 7 km km. The same technology has helped in 1977 discovered Uranus aura.
Brad Gary Booth said the aura around Chariklo discovery solves a mystery michael kors magasin about this celestial body. Earlier analysis of the spectra of mercurial the asteroid discovered its composition changes over time. Of ice and consisting of a halo, sometimes just the observer side face barbour france soldes Throat of the earth, sometimes it is the forward face of the observer, which is almost completely abercormbie outlet explain this anomaly previously found.
Francis De Miao (Francesca
DeMeo) is a planetary scientist at the Harvard-Smithsonian Center for ray ban sunglasses sale Astrophysics, he said the results convincing. She said: The removal of this possibility, it is difficult to use other ways to explain the observed phenomena. But how exactly is this aura formed is still a mystery. Astronomers speculate other small objects struck Chariklo, resulting in a lot of detritus is sputtering out, forming a halo structure. Other possibilities include: substance aura is as Chariklo's rotation is projectile out of the material, or this little day experience ever spontaneously releasing dust or ice particles in the process abercrombie uk store of moving its orbit, like a nike tn 2014 Users can work o comet that. These possibilities are currently
