NGC 7023: The Iris Nebula

As flimsy cosmic petals, these clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of the constellation Cepheid. Sometimes called the Iris Nebula and duly cataloged as NGC 7023, is not the only nebula in the sky to evoke the imagery of flowers.

This extraordinary image shows the range of colors and symmetries of the Iris Nebula in great detail. Among Iris , dusty nebular material surrounds a hot young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. The Central filaments of the dusty clouds glow with a faint reddish photoluminescence caused by dust grains become radiation ultraviolet invisible star in visible red light.

Scientists recommend sailing the seas of Titan

The concept of a new mission to discover Saturn's largest moon is a machine capable of driving on the surface of Titan on the wheels, and then turn the boat and walk with blades and propeller on hydrocarbon seas second largest satellite solar system.

The mission of "Cassini-Hyuygens" Titan is actively studied in the 2000s, was able to stay a short time on the surface of its seas.

The new mission, called Titan Lake In-situ Sampling Propelled Explorer will land in the middle of the largest lake in Titan's called Sea Ligei will float to the coast, along the way making scientific measurements. The expedition will last from six months to a year.

Shock waves are concerned the solar system

The planets of our solar system could have formed at different times, with the participation of shock waves coming from the sun, according to an astronomer.

This theory presumes that the Earth is one of the youngest of the planets in the solar system, along with Mercury, Venus and Mars.

Curiosity found Martian river on mars

New NASA rover Curiosity discovered that, most probably, is the bed of a dried-up Martian flow indicating that the surface of the Red Planet once flowed a stream depth of about a meter.

Photos taken by the rover, found in layers of rock outcrops large, rounded stones. Their shape suggests that the stones were transferred water on the planet's surface over long distances.

Solve the mystery of the magnetic anomalies asteroid Oljato

Asteroid 2201 Oljato moving surrounded by the orbit of Venus shows a slightly extraordinary behavior. Past observations point to the associated magnetic phenomena, but new data from the unit Venus Express, show that the magnetic anomaly is suddenly no longer appear.

Team member mission Venus Express Dr. Christopher Russell explains the behavior of asteroid Oljato follows:

Vesta may be a tiny planet

Deep melancholy surrounding the asteroid Vesta, may indicate that the message has a complex structure, a characteristic not of asteroids, and to the planets, according to a new study.

Researchers led by Debra Butskovski (Debra Buczkowski) Applied Physics Laboratory of Johns Hopkins University in Laurel, Maryland, noted that grooves that extend to the surface of Vesta, are no cracks in the form of the letter V, which are usually formed on the surfaces of asteroids in the result their collision with other space objects, and so-called grabens - areas of the cortex, which fell on the level of the rest of the surface tectonic fault lines, so that the form of education closer to the letter U. 

Get the most accurate picture of Pluto, made with Earth

The planet, dwarf planet or Kuiper Belt objects, so what's the difference? The main thing that astronomers the most detailed picture to date of Pluto ever do with ground-based observations.

And that's how they got it:

They did a series of pictures of Pluto and Charon, using a newly developed camera called Differential Speckle Survey Instrument (DSSI), which is mounted on an 8-meter telescope of the Gemini North, located in Hawaii.
