Approximate launch date project venera-D

"In this project, we are currently conducting research and development. The launch will be in 2020-2025, "- said the head of the Federal Space Agency.

Under the "Venera-D" will send two to Venus orbiter and a lander. After the failure of the mission "Phobos-Grunt" in the fall of 2011, this project, like many others ("Mars-Nat", "Mercury-P", "Venera-D", "Spectrum-RGM" and "Spectrum-UFM") is under threat. Even report the closure of projects, but that information was later refuted.

Scientists have built-up a geological map of Venus

U.S. and Russian planetary scientists developed the first complete geological map of Venus and presented it to the third Moscow Solar System Symposium on Space Research Institute (IKI) RAS.

"The map has helped us to find out what life in the earth, there were two periods of Venus - tectonic and volcanic his descendant. According to our calculations, the" morning star "is quite young - the average age of rocks on the surface is about 500 million years," - said one of the authors cards, Mikhail Ivanov of the Institute of Geochemistry, Vernadsky (Vernadsky).

The supernova remnant Simeis 147

This structure, also referred to in catalogs as Sh2-240, covers an area of ​​nearly 3 degrees on the sky (the equivalent of 6 full moons). The mentioned field corresponds to an actual diameter of about 150 light-years, since the debris cloud is at an estimated distance of 3000 years-light. The bright star that dominates the right side of the image is El Nath (Beta Tauri), located toward the boundary between the constellations of Bull (Taurus in Latin) and the Charioteer (Auriga in Latin), on a point of land almost exactly sky opposite to the galactic center.

Declassified U.S. military specifications UFO

National documentation of the United States for the first time published the secret blueprints flying saucer, which was developed in the 1950s for the U.S. Air Force. The device is called Project 1794 (the "Project 1794").

According to the posting of the document dated June 1, 1956, a UFO was designed for vertical takeoff and landing and had a speed of three to four Mach numbers (from 3200 to 4300 kilometers per hour). Altitude flying saucers - over 30 kilometers, and the maximum range - about 1800 kilometers.

Planetary Nebula Abell 39

Let's look at a planetary nebula nearly perfect spherical shape, whose name Abell 39 (Abell 39).

Today in our galaxy "Milky Way" is known more than 1500 planetary nebulae that are astronomical substance consisting of ionized gas shell and the central star - a white dwarf. Planetary nebulae are fast in astronomical terms the phenomenon, which lasts only a few tens of thousands of years. For comparison, the life of the parent star is a few billion years.

The universe is increasing, what threats the Earth

NASA Jet Propulsion Laboratory reported that the astronomers who work with the Space Telescope, "Spitzer", were able to conduct a more accurate calculation of the rate of increase in the history of astronomy. In other words, this swiftness is called the Hubble constant.

We live on a small planet Earth, but this does not preclude our interest in the rest of the world. But to know the size of this huge, compared to us, the world, to find out what the age and expansion rate of the universe has. More recently, you can also add the concept of "acceleration of the expansion." But the accelerated expansion of the universe, you can still stick to the linear Hubble law.

Draconid meteor shower reaches peak activity on Monday

Draconid meteor shower on Monday to reach peak activity, although this time, astronomers do not expect a "star storm" as last year, but it is possible that this meteor shower will present scientists surprises. Meteors occur when the atmosphere and there are burn microscopic dust particles. Meteor streams or Star rain associated with the passage of the Earth through the dust, who reserves the comet.
