Moon is younger than first thought

Improved age data for the Moon suggests that it is much younger than previously believed according to scientists presenting at a Royal Society discussion meeting entitled Origins of the Moon this week (23 September). Professor ...

Solar system's youth gives clues to planet search

Comets and meteorites contain clues to our solar system's earliest days. But some of the findings are puzzle pieces that don't seem to fit well together. A new set of theoretical models from Carnegie's Alan Boss shows how ...

ALMA: World's largest ground-based space array to open in Chile

In a super-arid desert at an altitude of 5,000 meters, with almost no humidity or vegetation, the world's largest ground-based astronomy project opens for business on Wednesday ready to probe the universe with unprecedented ...

Unlocking the mystery behind Saturn's moonlets

(Phys.org)—Research by Loughborough University physicists casts new light on Saturn's moonlets – and could help solve some of the mysteries surrounding planet formation.

The water reservoir in a young planetary system

(PhysOrg.com) -- Astronomers once thought that the process of star formation was more-or-less controlled by the simple coalescence of material by gravity, leading eventually to a new star. But they have come to realize that ...

Rocky planets could have been born as gas giants

When NASA announced the discovery of over 1,200 new potential planets spotted by the Kepler Space Telescope, almost a quarter of them were thought to be Super-Earths. Now, new research suggests that these massive rocky planets ...

Measuring the clumpiness of proto-planetary disks

(PhysOrg.com) -- The process of star formation, once thought to involve just the simple coalescence of material under the influence of gravity, actually entails a complex series of stages, with the youngest stars assembling ...

Assumptions about exo-oceans

Some estimates indicate that 25% of Sun-like stars have Earth-like planets. A new study now shows that these planets are almost certain to have oceans if they are located in the right temperature zone around their host stars.

Back to the roots of the solar system

(PhysOrg.com) -- Planets form in disks of dust and gas that surround young stars. A look at the birth places means a journey into the past of the earth and its siblings. Now, astronomers have been able to obtain detailed ...
