Planet Earth, the Solar system . and all the stars visible to the naked eye are in the milky Way Galaxy . which is a spiral galaxy with a jumper with two distinct sleeves starting at the ends of the jumper.
This was confirmed in 2005 a space telescope named the Lyman Spitzer, which showed that the centre bar of our galaxy is larger than previously thought. Spiral galaxy barred spiral galaxy barred (“bar”) of bright stars emerging from the center and crossing the galaxy in the middle. Spiral branches in these galaxies begin at the ends of the crosspieces, whereas in normal spiral galaxies, they come directly from the kernel. Observations show that about two thirds of all spiral galaxies have a bar. According to existing hypotheses, the jumpers are centers of star formation, supporting the birth of stars in their centers. It is expected that through orbital resonance, they are passed through a gas of spiral branches. This mechanism provides a flow of building material for the birth of new stars. Milky Way along with the Andromeda galaxy (M31),Triangle (M33), and more than 40 smaller galaxies-satellites, form the Local Group of Galaxies, which, in turn, is part of the Virgo Supercluster. “Using infrared images from NASA Spitzer telescope allowed scientists to discover that the elegant spiral structure of the milky Way has only two prevailing sleeves from the ends of the Central bar of stars. Previously it was thought that our galaxy has four main hoses “. Continue reading
Matt Taylor – the adventures of Rosetta
Caught the comet British astrophysicist Matt Taylor told the guests of the festival 360° about the Rosetta mission. about why study comets in General, and about their own role in this Grand project. We have selected a few interesting quotes from Kinot-speech for those who for some reason missed the lecture or watched the broadcast.
About comets in General
I will tell you about their history, about their view on what the Rosetta mission, because I am only a small part of a huge team. So why do we study comets?
This film, created by Polish Studio Platige Image jointly with ESA] was released shortly before docking of the probe Philae from the comet. Its task is to explain the purpose of our mission. We hope to learn more about the evolution of the Solar system – where did we come from? Therefore, it is important to understand how on Earth there was water.
Here’s what we know about comets after all observations. Their Central core is very small if to compare with the “tail” of dust and gas that the comet emits. Continue reading
Russia will fly into space on a nuclear engine. Go work on the creation of such a transport and energy module. This was stated by the head of Roscosmos Vladimir Popovkin in a holiday interview to “Rossiyskaya Gazeta”. Today, the country celebrates the Day of cosmonautics. Popovkin said that it is a compact machine with a capacity of one megawatt, the modules will be used in the composition of the inter-orbital tugs and even for interplanetary missions. Mass no analogues in the world.
Yuri Yurievich, what do you think? How realistic is it to create such a setup? How it would function?
Karash: to Create it, of course, real. As far as using it for interplanetary flights – it makes sense. With regard to inter-orbital tug – it is like flying on Boeing-474 from Moscow to Kaluga. I need to use nuclear installation does not see. But if you work its action somewhere within the Earth, then it certainly makes sense. In General, the use of nuclear thrust for interplanetary missions is the most promising.Suffice it to say that the company estimates MSNW (it’s an American company that, together with universitatsstra Washington now developing the nuclear rocket engine), with the use of this type propulsion system flight to Mars and back can be placed in the interval from 30 to 90 days.
