Edmund Halley opening date

Discoverer: named after Edmund Halley opening date: 1758 (first predicted perihelion) Alternate designations: comet Halley (Halley), 1P Orbital characteristics: Age: 2449400.5 (17 February 1994) Aphelion: 35.32.e. Perihelion: 0.586.e. The semi-major axis: 17, 8 and.e. The eccentricity repulsed: 0, 967 Orbital period: 75, 3 and the Inclination of the orbit to the Ecliptic plane: 162, 3 degrees Last perihelion: 9 February 1986 Next perihelion: 28 July 2061 g the Period of revolution around the Solar system: from of 74.4 to 79.2 years. The average value of 76 years. Thanks to a successful “visits” in 1986 to comet Halley spacecraft “VEGA-1 and VEGA-2” (USSR) Giotto (ESA), “Suisei” and “Sakigake” (Japan) scientists got the first pictures of the core and comprehensive information:

Unique comet

Leaving the Oort cloud, the Earth is approaching comet Catalina, consisting of primordial matter.

Comet C/2013 US10 Catalina has completed journey around the Sun and is now approaching Earth. The comet will fly at a distance of 108 million km from the planet. It can be seen with the naked eye or in binoculars 17 January 2016 in the area of the constellation URSA major, reports Global Science .

The comet opened in October 2013 with the help of automated search system, which was developed under the project called the Catalina Sky Survey, providing a view of the sky.

C/2013 US10 is one of the many comets are in the Oort cloud, located at a distance of 50-100 thousand astronomical units.

Experts believe that the cloud is material left from the formation of the entire Solar system.

The first Catalina circled around the Sun took place at the end of November. Now the comet can be observed in the constellation of Virgo, however, this requires special optics. Continue reading

Do I need to be perfectly healthy to fly in space?

The main problems during space flight are considered motion sickness, fatigue, dehydration, loss of appetite and back pain

The astronauts can perform on the International space station not more than six months. And for good reason.

The loss of muscle and bone mass in zero gravity during this time is so great that the continued presence in space for humans is not possible.

Future space tourists will not go through the same tough training as cosmonauts and astronauts – how flying can affect their health?

In an article published by the British medical journal, argues that the district doctors in British clinics need to be prepared for the fact that in the near future, their patients will begin to wonder whether their body to move space travel.

Only a handful of doctors have sufficient knowledge in the field of space medicine to give expert advice. Continue reading
