Major Scientific Discovery on Extrasolar Planets. NATURE, the scientific journal, will publish on the 26 January 2006, a major paper on a discovery addressing extra-solar planets. The European Southern Observatory ESO contributed to this publication and has produced a Video Ne...

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...

It is only a matter of time before astronomers find an Earth-sized planet orbiting a distant star. When they do, the first questions people will ask are: Is it habitable? And even more importantly, is there life present on it already? For clues to the answers, scientists are looking to their home plan...

The researchers say that the discovery could be a sneak peek at the fate that awaits the Earth, some four or five billion years from now...

NASA researchers recently discovered the largest solid core ever found in an extrasolar planet, and their discovery confirms a planet formation theory. "For theorists, the discovery of a planet with such a large core is as important as the discovery of the first extrasolar planet around t...

Giant stars with planets often have smaller amounts of heavy elements than the Sun, say astronomers in the United States and Germany. This trend is surprising: it is opposite the one seen in planet-bearing main-sequence stars and suggests stars more massive than the Sun may give birth to planets in...

On March 26, 1859, a French medical doctor and amateur astronomer named Lescarbault claimed to have observed a planet closer to the sun than Mercury. He called it Vulcan, after the Roman god of fire. He calculated the planet's movements and sent the information onto Urbain Le Verrier, France's most...

Discovery of a new planetary system similar to the Solar System A group of European astronomers has discovered a planetary system with at least five planets, but it could have two more, around a sun-like star, HD 10180. The number of planets and their distances from the star makes this system resemb...

Huddled over a computer in his bedroom, Kevin Apps could barely believe what he had found. From his modest bungalow near Gatwick Airport, he had spent days poring over observations sent back to Earth by a telescope orbiting our planet. While Nasa had a team of more than 30 full-time scientists analys...
