For the first time, astronomers have observed the initial phase in the formation of an earth-like planet. What astronomers observed was that a protoplanetary disk, or ring, around the binary star known as KH 15D, is composed of solid particles larger than what is usually observed in space. picked by AutumnLotus 6 months ago

Astronomers have discovered the first known planet to survive its "red-giant" phase, a period when an aging star expands and engulfs bodies orbiting it. The discovery of the gas-giant planet three times the size of Jupiter offers a look at the future of our own solar system and what will happen to the Earth when the sun grows old and collapses. picked by AutumnLotus 12 months ago

"Astronomers on Wednesday announced they had spotted the first planet beyond the Solar System that has water, the precious ingredient for life." picked by deepchill 1 year ago

Astronomers have announced the discovery of a fifth planet circling 55 Cancri, a star beyond our solar system. The star now holds the record for number of confirmed extrasolar planets orbiting in a planetary system. picked by AutumnLotus 10 months ago

Planet-seekers who have spotted 28 new planets orbiting other stars in the past year say Earth's solar system is far from unique and there could be billions of habitable planets. picked by AutumnLotus 1 year ago

Scientists at the Max Planck Institute for Astronomy in Heidelberg have discovered the youngest known extrasolar planet. Its host star is still surrounded by the disk of gas and dust from which it was only recently born. This discovery allows scientists to draw important conclusions about the timing of planet formation. picked by AutumnLotus 8 months ago

Leading astronomers declared Thursday that Pluto is no longer a planet under historic new guidelines that downsize the solar system from nine planets to eight. picked by jaxomlotus 2 years ago

Organic molecules – in the form of methane – have been detected on a planet outside our solar system for the first time. The giant planet lies too close to its parent star for the methane to signal life, but the detection offers hope that astronomers will one day be able to analyse the atmospheres of Earth-like worlds. picked by AutumnLotus 7 months ago

Astronomers said Wednesday that they had found a miniature version of our own solar system 5,000 light-years across the galaxy — the first planetary system that really looks like our own, with outer giant planets and room for smaller inner planets.

They also found signs of Elvis and Amelia Earhart. picked by mahler87 7 months ago

A team of amateur and professional astronomers has discovered a mammoth orb more than 13 times the mass of Jupiter that whips around its parent star in fewer than four days and is considered an "oddball" planet among its exoplanet relatives. picked by AutumnLotus 1 year ago

Water has been identified for the first time in the atmosphere of a planet outside the Solar System. picked by AutumnLotus 1 year ago

Planets may be present in a quadruple star system 150 light years from Earth, according to Spitzer Space Telescope observations. The system, called HD 98800, consists of two pairs of stars in which the partners in each pair orbit one another closely. The pairs themselves travel around each other on a very elongated path. picked by AutumnLotus 1 year ago

Astronomers with the Trans-atlantic Exoplanet Survey today announce the discovery of their third planet, TrES-3 in the constellation Hercules about 10 degrees west of Vega. The new planet was identified by astronomers looking for transiting planets — that is, planets that pass in front of their home star. picked by AutumnLotus 1 year ago

University of Arizona astronomers who are probing the oxygen-rich environment around a supergiant star with one of the world's most sensitive radio telescopes have discovered a score of molecules that include compounds needed for life. picked by AutumnLotus 1 year ago

A planet outside our solar system with a year roughly equal to Earth's has been discovered around a dying, red giant star. picked by AutumnLotus 1 year ago

Science fiction may soon become science fact. Astronomers at NASA's Jet Propulsion Laboratory have recently concluded that the upcoming planet-finding mission, SIM PlanetQuest, would be able to detect an Earth-like planet around the star 40 Eridani, a planet familiar to "Star Trek" fans as "Vulcan." picked by AutumnLotus 1 year ago

An international team of astronomers with the Trans-atlantic Exoplanet Survey announce today the discovery of TrES-4, a new extrasolar planet in the constellation of Hercules. The new planet was identified by astronomers looking for transiting planets – that is, planets that pass in front of their home star – using a network of small automated telescopes. picked by AutumnLotus 1 year ago

A team of astronomers says it may have spotted the youngest planet ever found, boasting an age of less than 100,000 years old, and perhaps as young as 1600 years old. They say it bolsters a controversial theory that planets form very quickly, like stars – but other astronomers say the massive object may not be a planet at all but a 'failed' star, which explains its speedy birth. picked by AutumnLotus 5 months ago

It is the rare gas giant planet that inhabits the outskirts of its solar system. Most are like our own Jupiter and prefer to stick close to their stars, a new study suggests. picked by AutumnLotus 1 year ago

Researchers have dated the earliest step in the formation of the solar system - when microscopic interstellar dust coalesced into mountain-sized chunks of rock - to 4,568 million years ago, within a range of about 2,080,000 years. The dates established by analyzing a particular type of meteorite, called a carbonaceous chondrite, which represents the oldest material left over from the formation of ... read full post picked by AutumnLotus 9 months ago
