The hottest planet ever discovered is charcoal black and makes even some stars seem cool. Scientists think the exoplanet absorbs nearly all the starlight that reaches its surface and then reradiates it back out into space as heat. picked by AutumnLotus 1 year ago

The new definition, proposed this week by the International Astronomical Union (IAU), basically says every round object orbiting the sun is a planet, unless it orbits another planet. Asteroid Ceres will become a planet. Pluto's moon Charon will become a planet, things could get really strange. picked by Jaxomlotus 2 years 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 9 months ago

Classic sci-fi film cut down to half an hour and given the feel of a Twilight Zone episode. Why? Because of the involvement of Rod Serling in both - and the whopping great twist! picked by TheStep 2 years 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

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

Two rocks found together in Antarctica are chunks of a dwarf planet that was smashed apart early in the solar system's history, detailed studies suggest. Other remnants of the proto-world may still be floating around in the asteroid belt, and might be identifiable by the spectrum of the sunlight they reflect. picked by AutumnLotus 7 months ago

The solar system's smallest planet has been shrinking at an unexpected rate, researchers announced on Thursday.

When NASA's Mariner 10 probe flew by Mercury in 1974 and 1975, it returned images of strange cliffs called 'scarps' that cut across all sorts of geological formations. That suggested that the planet's surface has contracted over time. picked by AutumnLotus 3 months ago

Astronomers have peered into the womb of a stellar disk to capture an image of material falling onto what could be a planet in an early stage of formation. picked by AutumnLotus 7 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 1 year ago

The tell-tale signature of the molecule methane in the atmosphere of the Jupiter-sized extrasolar planet HD 189733b has been found with the Hubble Space Telescope. Under the right circumstances methane can play a key role in prebiotic chemistry – the chemical reactions considered necessary to form life as we know it. picked by AutumnLotus 7 months ago

Astronomers have discovered what may be the smallest alien planet yet — a rocky ``SuperEarth'' only four times heavier than our home planet. picked by AutumnLotus 4 months ago

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 7 months ago

Our planet is changing before our eyes, and as a result, many species are living on the edge. Yet Earth has been on the edge of habitability from the beginning. New work shows that if Earth had been slightly smaller and less massive, it would not have plate tectonics-the forces that move continents and build mountains. And without plate tectonics, life might never have gained a foothold on our wor... read full post picked by AutumnLotus 9 months 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

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.
