Coma of the comet

The comet’s coma or head of the comet . is a fuzzy mist surrounding the actual nucleus of the comet. Including the tail, the coma is all we actually see, watching the comet from the Earth.

The shape and structure of the comet’s coma

The shape of the coma can vary from comet to comet and for the same comet during its passage, depending on its distance from the Sun and the corresponding quantities of dust and gas. Pale or bright comets producing little dust and often have a round shape, and comets that produce a significant amount of cometary dust have fan-shaped or parabolic shape.

This is due to released different-sized dust grains: those that are bigger are moving to the left along the trajectory of a cometary orbit, and the smaller particles are repelled from the Sun using light pressure.

Coma has 2 main components: gas-shell and shell dust. In fact, scientists believe that comets produce almost the same amount of gas and dust. Continue reading

Sport in space begins with a football in zero gravity

So, according to the company, Space Island Group, might look like orbiting the stadium. The game tourists in the ball channels could broadcast live .

Weightless — what is not a reason to invent a whole new class of sports? After all, space sports of one type or another, more than likely. Especially due to the rapid development of the private aerospace business and the increased number of space tourists. Is it any wonder that competition in zero-gravity invented today?

If we talk about professional cosmonauts or astronauts, sports games in orbit for them is obvious. Given the fact that in the future the crews of the expand, and the missions will be very long, like missions to the moon or Mars.

A peaceful “battle” with each other under conditions of zero gravity could help space travelers not only to diversify the flight, but also to maintain health, physical and mental. But for space tourists sport in space can be a great added attraction. Continue reading

Space probe approaching Pluto after 9 years

The NASA probe New Horizons close to Pluto and will be able to enter the planet’s atmosphere in July of this year

Span New horizons near Pluto in the artist’s impression of NASA.

The ship, which was launched back in 2006 has come nearer to the outer body at a distance that allows you to make high-quality pictures of its surface.

NASA may have to adjust its trajectory in case of detection of unknown cosmic bodies, reports Russia Today .

Apart from the modern equipment on Board the spacecraft is an urn with the remains of the discoverer of Pluto Clyde Tombaugh (1906-1997), CDs with a message to aliens, U.S. coins, flags and postage stamps. On Board the SPACECRAFT is the CD 434 738 names of people who participated in the campaign NASA “Send your name to Pluto” (Send Your Name to Pluto).

Task apparatus is the study of the atmosphere and the ground layers of Pluto, moreover, New Horizons will create a map of the surface of the farthest planet in our System. Continue reading
