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.

kepler-37b exoplanet

The Smallest Exoplanet Kepler 37b

Astronomers discovered a little exoplanet, which has less dimensions and weight, than the smallest planet Mercury in the solar system. The planet Kepler 37b moves around the star in Lira constellation every 13 days. It has 210 light years distance from the Earth. This planet is stone planet, and has approximately 427 Celsius temperature, because of that fact, there cannot go any speech about life.The moon-size Kepler 37b is so close to its parent star, at just 0.10 AU, that it likely has no atmosphere or liquid water on its surface.Kepler 37b was discovered by telescope “Kepler”. The $600 million Kepler mission launched in March 2009, and has found more than 2,740 candidate alien worlds so far.

Habitable Exoplanets catalog

Habitable Exoplanets Catalog

Scientists published habitable exoplanets catalog to list all the known planets in the galaxy that could potentially be habitable to life. The count is at seven so far, with many more to come, researchers said. When it was first released last year, it had two potential habitable planets. According to lead researcher Abel Mendez director of the University of Puerto Rico the team expected to add maybe one or two more in the catalog’s first year. The addition of five suspected new planets was wholly beyond anyone’s expectations. Mendez also said scientists are getting smarter about finding exoplanets, and the pace of discovery is increasing. The team expects to add new models in the coming year, which will affect the measurements on objects already in the catalog.

Rogue alien planet

Rogue Alien Planet CFBDSIR2149

Astronomer Philippe Delorme from the Institute of Planetology and Astrophysics of Grenoble in France and his team discovered  a potential rogue alien planet  CFBDSIR2149 using the Canada-France-Hawaii Telescope, wandering alone just 100 light-years from Earth, suggesting that such starless worlds may be extremely common across the galaxy.The free-floating object, called CFBDSIR2149, is likely a gas giant planet four to seven times more massive than Jupiter, scientists say in a new study unveiled today (Nov. 14). The planet cruises unbound through space relatively close to Earth (in astronomical terms; the Milky Way galaxy is 100,000 light-years wide), perhaps after being booted from its own solar system.

Scientists Have Discovered New Type of Alien Planet

Scientists have discovered a new type of alien planet.The standard-bearer for this new class of exoplanet is called GJ 1214b, which astronomers first discovered in December 2009.GJ1214b is a super-Earth orbiting a red-dwarf star 40 light-years from Earth in the constellation Ophiuchus (The Serpent Bearer). New observations from NASA’s Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. GJ1214b represents a new type of planet, like nothing seen in our solar system or any other planetary system currently known. To date, astronomers have discovered more than 700 planets beyond our solar system, with about 2,300 more candidates awaiting confirmation by follow-up observations but according to researchers GJ 1214b, is something new altogether. This so-called super-Earth is about 2.7 times Earth’s diameter and weighs nearly seven times as much as our home planet.
