Flash of the supernova

Astronomers confirmed the disappearance of star in flash supernova

Researchers from several American scientific centers, including university of California, presented results of supervision over a place of flash of supernova M51 in a galaxy. Supervision was conducted with help of Hubble telescope, rather small automatic telescope on a surface of planet. Flash of the supernova was noticed on May 31, 2011 and it was seen only by owners of big telescopes as visible brightness of a star reached only to 12. Astronomers received a range of radiation supernova and by absence in it characteristic lines of hydrogen determined accident type: IIb. It means, that the disappearance of star was with a certain partner, who drew on itself considerable part of a hydrogen cover then the part, which has remained and consisting mainly from helium.

Protostars discovered by Hershel telescope

Telescope Hershel Found Young Protostars

In frames of NASAs’ mission of European Space Agency (ESA), the astronomers found some youngest stars in the Orion Molecular Cloud Complex . These stars were discovered by some astronomers from different observatories from Sweden and Germany. These astronomers collaborated in the European Space Agency (ESA) mission for understanding the formation of new stars. The discovery gives the chance to scientists to understand the formation of the star. The star comes to life from the gravitational collapse of gas and dust clouds. Finding the protostars in the earliest time, poses a challenge. For a long time the astronomers had observed the Orion Molecular Cloud Complex, but had not found any new forming star, until the Herschel telescope observed the region. Herschel found the protostars by infrared, long-wavelength light, which can shine through the clouds.

Exoplanet HR8799c

HR8799c Exoplanet Atmosphere contains Water Vapor

In the atmosphere of an alien planet HR8799c, which distance from the Earth is approximately 130 light years, the astronomers found vapor of water and carbon monoxide. The astronomers say that in the HR8799c planet, there is no methane, which is a gas that indicates life. The astronomical measurements, which the astronomers did during their observations, are the most precise measurements, which the astronomers have ever made outside of our solar system. Astronomers have founded over 1000 planets beyond our solar system since 1990. Among them the HR8799c is the huge planet. The mass of HR8799c, is approximately seven times more that the mass of Jupiter, which is the largest planet in our solar system. It circles a star with three other planets.

Solar System nearest Star Systems

Solar System nearest Star Systems

It seems that astronomers may have new chance to search exoplanets. The new star system, which was discovered 1917 and approximately 6.5 light years away from our solar system, is the third nearest to our solar system. The new stars are brown dwarfs- cool, dim objects. The pair of stars has chemical properties and high temperature. This kind of objects, often, referred as a “failed stars”. This “failed stars” doesn’t have enough mass for crushing by gravity, which would allow the thermonuclear reactions to ignite the hydrogen. The astronomer from the Penn State University Kevin Luhman, during the studying a map of the sky, which obtained from NASA’s satellite, discovered, that one of the stars has a rapid motion. The astronomer extrapolated the movement of star back in time and discovered, that it was really captured.

Gas giant HD 10056 source:NASA/ESA Hubble Space Telescope

Astronomers are witnessing Planet Forming Inside Gas Cloud Surrounding the Star HD 10056

HD 10056 is the young star which is near to the Earth about 335 light years. The astronomers, who are studying the HD 10056 star, think, that they are witnessing the birth of a giant from gas. This giant will be three times larger than Jupiter. If this discovery is confirmed, it will change the understanding of people, regarding the comparing the theories of scientists, with direct observations of new planets.

Pluto new satellites

People Voted for new Names for the Satellites of Pluto

In 2011 and 2012 the group of astronomers by leadership of Mark Showalter discovered twonew satellites of Pluto. These are the forth and fifth satellites of Pluto. The dimensions of P4 are from 13 up to 34 km, and the P5 are form 15 up to 24km. According to rules of the International astronomical union, the satellites have to receive the names from Greek-Roman mythology, which is connected with underground kingdom of Aida. The discovers offered 12 mythology names, and everyone can vote for the name, which likes to him. In the voting totally participated 450 people, from them 174,000 voted for Volcano (the Roman God of underground fire), and 99,400 voted for Cerberus (the three-headed dog guarding a gate of the underground world).

Galaxy NGC660

Unusual Galaxy Photographed from Gemini Observatory

Astronomers from Observatory “Gemini” received the most detailed to date image of the unusual galaxy NGC 660, relating to a rare class of polar galaxies. The galaxy NGC 660 is located at a distance of 40 million light years from Earth near the constellation Pisces. It is as if two separate star clusters: the spiral and lenticular. Such galaxies are called polar – they rotate the outer ring over the poles of the internal cluster. In addition, NGC 660 is the only other known polar galaxies in which the center has an old lenticular congestion. All polar galaxies are a result of the interaction of two separate star clusters. Some of them can be formed by the collision of two galaxies formed (for example, a galaxy can be formed by a merger in the future, with the Milky Way Andromeda).

Explosion on Jupiter

Explosion on Jupiter Captured Amateur Astronomers

American amateur astronomers Dan Peterson and George Hall  recorded a explosion on Jupiter caused by the fall of a large meteorite. Dan Peterson watched the gas giant with the twelve-inch amateur telescope. On Monday at 11:15 GMT, he discovered explosion on Jupiter, which took about 1.5-2 seconds. Scientists estimate that it caused the fall of a meteorite with a diameter of about 10 meters. The fall of large meteorites and explosion  on Jupiter – not very rare. Until 2010, they were recorded in 2009 and 1994.
