New planet discovered ?

The planet (left) is about five times the size of our Jupiter. European and American scientists say they have photographed a planet outside the Solar System for the first time. The European Southern Observatory group said the red image is the first direct shot of a planet around another star. The planet, known as 2M1207b, is about five times the size of Jupiter and is orbiting at a distance nearly twice as far as Neptune is from our Sun. The parent star and planet are more than 200 light-years away near the southern constellation of Hydra. There has been a lot of competition among astronomers to secure the first direct picture of an exoplanet. When the ESO group first released the picture last September there was doubt over whether the star and planet were gravitationally bound. But follow-up images taken at the Very Large Telescope facility in Chile show the two objects are moving together. “Our new images are quite convincing,” said Gael Chauvin, an Eso astronomer. “This really is a planet – the first planet that has ever been imaged outside of our Solar System,” he added.
Tough task
It is extremely difficult for current technology to detect exoplanets – let alone get a clear shot of one. All of the 130 or so exoplanets so far discovered have been found using indirect methods – looking for changes in the properties of stars (their brightness or way they move) that can be explained only by the presence of a planet. Now we have a direct observation, the Eso team says. The star has the uninspiring catalogue number 2M1207A. It is a brown dwarf, or “failed star” – an object whose mass of hydrogen and helium has failed to trigger the nuclear reactions that would make it shine brightly like normal stars. At the time of 2M1207b’s discovery, it was impossible to prove that the red speck caught in the original images was not a background object, such as an unusual galaxy or a peculiar cool star.
The new observations show with high confidence that the two objects are moving together and hence are gravitationally bound. “The two objects – the giant planet and the young brown dwarf – are moving together; we have observed them for a year, and the new images essentially confirm our 2004 finding,” said Benjamin Zuckerman, a University of California-Los Angeles (UCLA) professor of physics and astronomy. Anne-Marie Lagrange, another member of the team from the Grenoble Observatory in France, looks towards the future: “Our discovery represents a first step towards one of the most important holy grails of modern astrophysics: to characterise the physical structure and chemical composition of giant and, eventually, terrestrial-like planets.”
En wanneer zou Baobab deze exotische bestemming in de kleurrijke catalogus opnemen:drunk_tb:?Of moeten we daarvoor bij Summum zijn?

Ja ik dacht dat er iets fout ging, vandaar tweede poging….Nooit te oud om wat bij te leren!
Nou, volgens mij hoeven we daarvoor helemaal niet bij Baobab of Summum te zijn, maar kunnen we gewoon bij de webmaster rechtsreeks boeken.
Want hij weet volgens mij alles van dat soort bestemmingen. :smileywink_tb:

Ik mag van jullie niet eens alleen naar Tuvalu, dus er zal heel wat overtuigingskracht voor nodig zijn voordat iemand mee kan naar dit soort bijzondere bestemmingen….
Nou, maar denk erom ….. als wij niet mee mogen, gaat Nina ook niet mee hoor !! :kiss_tb:
Wie is Nina in vredesnaam ? :ohh_ee:
Ja, ja, ….. mijn naam is haas!!! :dunce_tb:
Weet je nog ??:
:tongue_tb:
Nou ik wil best wel mee naar Tuvalu hoor webmaster, laat maar weten wanneer:clap_tb:!!
Hanny, laat die hoop maar varen …. hij wil ons gewoon niet mee hebben !!
Maar goed, daar krijgt hij nog spijt van ….hij zou toch moeten weten wat ie dan mist, toch?
:doh_tb:
Nou ik mis toch niets met Nina aan mijn zijde :

Nou, dat weet je niet …… zo’n pakje zegt niet alles hoor! :tonguewink_ee:
