Around the Solar system
Top 5 for the day
Automatic interplanetary scouts NASA, the European space Agency and others currently collecting information about our Solar system. Right now the spacecraft are in orbits of Sun, mercury, Venus, Earth, Mars, and Saturn, flying to other small space objects.
Thanks to the astronauts and to all automatic mechanical scouts in space, we have the opportunity to see “family” Photos of our Solar system.
Recover in the journey.
For a start look at our Earth. It looks like Moscow, when the ISS passes over the territory of Ukraine, February 2, 2015. Scientific evidence indicates that Earth formed from the solar nebula about of 4.54 billion years ago. Presumably life appeared on Earth about 3.9 billion years ago, i.e. during the first billion after its occurrence.
So it looks from space, the Salt flat of Uyuni — dried salt lake in the South of the desert plain Altiplano, Bolivia at an altitude of about 3 650 m above sea level. The inner part is covered with a layer of salt thickness 2-8 m During the rainy season salt marsh covered with a thin layer of water and turns into the world’s largest mirror surface.
New York, August 25, 2014.
A Part Of Europe. Lights are out in people’s homes on the plains and in mountain valleys, on 7 February 2015.
Glaciers near greizerstein and Chile, on 27 January 2015.
Partial solar Eclipse, October 23 2014.
Went on mercury — the closest planet to the Sun in the Solar system. It is the smallest planet of terrestrial group. Conditions are harsh: the temperature on mercury’s surface ranges from -180 to +430 °C.
The surface of mercury is also in many respects reminds lunar — it is much katerinovka. The crater van Eyck, named after a Danish artist. Its diameter is 235 meters.
One of the most anticipated space events of the past year is the passage of comet C/2020 A1 Siding Spring near Mars in October 2014. This comet approaching the red planet at a minimum distance of 138 thousand km, which is very close. For comparison, our Moon is at a distance of 384 thousand km and geostationary satellites hang in 40 000 kilometres from the surface.
Curiosity Rover on Mars, November 23 2014. This is the fourth farthest from the Sun and seventh in size planet in the Solar system; the mass of the planet is 10.7% of the mass of the Earth. Sometimes Mars is called the “red planet” because of the reddish hue of the surface, attached to it by iron oxide.
The surface of Mars and the Curiosity Rover (the dot in the center). The picture was taken with multifunctional automatic interplanetary station Mars Reconnaissance Orbiter.
Martian landscapes. It is the highest on Mars and the highest known in the Solar system, mount Olympus. Olympus is about 27 km height relative to the base.
Comet 67P/Churyumov — Gerasimenko. The picture was taken on November 22, 2014 from a distance of 30 km the Index of 67P means it is a 67 short-period (orbital period around the Sun less than 200 years) comet. According to recent estimates, the mass of the comet is about 10 billion tons.
2 March 2004 launched the spacecraft “Rosetta”, whose main objective is to study the comet Churyumov — Gerasimenko. The machine reached the comet in summer 2014. It separated from the lander “Fily” landed on 12 November 2014 at 19:05 GMT.
Comet 67P/Churyumov — Gerasimenko. The picture was taken on 10 December 2014 from a distance of 20 km.
Comet 67P/Churyumov — Gerasimenko. Comet Churyumov — Gerasimenko was opened October 23, 1969 by Soviet astronomer Klim Carumonam.
Comet 67P/Churyumov — Gerasimenko on 31 January 2015. In the publications of the ESA form the nucleus of the comet was compared with a toy rubber duck.
We are near Jupiter on 24 January 2015. Here you see three of its largest satellites. Jupiter is a gas giant and the fifth planet from the Sun, largest in Solar system. Its radius is equal to 71.4 thousand km, which is 11.2 times the Earth’s radius and mass at 2.47 times the total mass of all other planets in the Solar system put together (317.8 times the mass of Earth). The mass of Jupiter only 1 000 times less than the mass of the Sun itself.
Europe — the sixth moon of Jupiter. The surface consists of ice and is one of the smoothest in the Solar system; it contains very few craters, but many cracks. Very apparent youth and smoothness of the surface have led to the hypothesis that water is under the ocean.
A Saturn, on 23 August 2014. In the background you can see its rings. The sixth planet from the Sun and second largest planet in the Solar system after Jupiter. Saturn consists mainly of hydrogen, and the wind speed on the surface in some places can reach 1800 km/h.
Rings of Saturn — system of flat concentric formations of ice and dust. The thickness of the rings is extremely small compared to their widths (from 7 to 80 thousand kilometers above the equator of Saturn) and ranges from one kilometer to ten meters.
Saturn Of Mimas. Having a size of about 400 kilometers, is the twentieth-largest satellite in the Solar system. A distinctive feature of Mimas is the huge impact crater Herschel, 130 km diameter, named in honor of the discoverer satellite. Probably far in the past with Mimasa faced a huge asteroid and formed the crater. The kick, apparently, nearly split the satellite. and the diameter of the crater is almost one third of the diameter of Mimas.
A large vortex of Saturn at its North pole. dimensions 2 000 km in diameter, the speed is 150 meters per second.
Titan is the largest moon of Saturn, the second largest satellite in the Solar system (after Jupiter’s Ganymede), is the only one, besides Earth, body in the Solar system for which we prove the existence of liquid on the surface. Titanium also exceeds the size of the planet mercury, though it is inferior for mass. The force of gravity on it is about one-seventh of the earth. The mass of Titan is 95 % of the mass of all of Saturn’s moons. The temperature at the surface minus 170-180 °C.
View from the orbit of Saturn. A bright dot is Uranus, the seventh farthest from the Sun, the third diameter and the fourth mass. Falls into the category of “ice giants”. Uranus is heavier than Earth 14.5 times. It is the coldest planetary atmosphere in the Solar system with a minimum temperature of -224 °C. the wind Speeds on Uranus can reach 250 m/s (900 km/h).
And this is our star — the Sun. October 8, 2014 it looked particularly devilish.
NASA timed the five-year anniversary of the solar dynamics Observatory (SDO) to release several videos, one of which is a timelapse with “everyday” life of the Sun for five years. Each frame contains a still image captured with an interval of eight hours. Over the same time SDO received more than 200 million the 2600 terabytes (2.54 PB):
