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

By looking at sun-like stars in their infancy, researchers have used a powerful telescope and a new bag of tricks to peer at planet-formation under way. The result: Three wildly different setups, suggesting our solar system is perhaps neither unique nor all that strange. picked by AutumnLotus 3 months 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 1 year ago

NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems. picked by Neiako 2 years 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

Enter your age and discover your age on other planets in our solar system. (Good link on here for building a scaled solar system too). Not completely updated: Pluto still a planet on this site. picked by ogri2003 1 year ago

Create your own system of planets. Change the direction and velocity of celestial bodies and keep them within your stars gravitational pull. Be sure to "select preset" at the top right & "set number of bodies" at bottom left. picked by ogri2003 1 year ago

Hundreds of millions — or even billions — of years after planets would have initially formed around two unusual stars, a second wave of planetesimal and planet formation appears to be taking place. "This is a new class of stars, ones that display conditions now ripe for formation of a second generation of planets, long, long after the stars themselves formed." picked by AutumnLotus 11 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 10 months ago

The Global Positioning System, relied on for everything from navigating cars and airplanes to transferring money between banks, may be threatened by powerful solar flares, a panel of scientists warned. picked by suebe 2 years ago

Using the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instruments on board NASA's Solar Terrestrial Relations Observatory (STEREO) spacecraft, a consortium of scientists has seen, for the first time, large waves of solar material sweeping past Earth. picked by AutumnLotus 12 months ago

Water has been identified for the first time in the atmosphere of a planet outside the Solar System. picked by AutumnLotus 2 years 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

In a find that sheds light on how Earth-like planets may form, astronomers this week reported finding the first evidence of small, sandy particles orbiting a newborn solar system at about the same distance as the Earth orbits the sun. picked by AutumnLotus 9 months ago

An image released today of a distant star and its potential planetary companion could go down in history as the first picture of a planet outside our solar system orbiting a sunlike star. picked by AutumnLotus 3 months ago

Chondritic meteorites have a similar chemical composition to the sun and are therefore reliable witnesses as to what the solar nebula, from which the planets formed, was composed of. This can be used to deduce what the Earth consists of chemically. However, ETH Zurich researchers have now discovered that strictly speaking this fundamental geological assumption is not true. picked by AutumnLotus 7 months ago

The fiery demise of a fifth rocky planet in our Solar System might have led to a flurry of asteroid impacts that pockmarked the Moon and Earth billions of years ago. picked by AutumnLotus 1 year ago

For the first time, astronomers think that they've found evidence of an alien solar system around a star close enough to Earth to be visible to the naked eye. picked by AutumnLotus 1 month ago

As humans look farther into the universe and discover more and more planets beyond the sun, many wonder how typical our own solar system is. Often astronomers in the planet-hunting business say discoveries of Earth-like worlds are just around the corner. But a new study indicates our setup may be rare indeed. picked by maxriter 5 months ago
