Ancient asteroids 'found' in solar system

Astronomers have identified three ancient asteroids which they claim are among our Solar System's oldest objects.

Astronomers Find Oldest Known Asteroids

Researchers from the University of Maryland have recently discovered three asteroids that appear to be roughly 4.55 billion years old, dating back to the formation of the Solar System. The scientists say that the asteroids have survived relatively unchanged since that time, and make good candidates for future space missions. "'The fall of the Allende meteorite in 1969 initiated a revolution in the study of the early Solar System,' said Tim McCoy, curator of the national meteorite collection at the Smithsonian's National Museum of Natural History. 'I find it amazing that it took us nearly 40 years to collect spectra of these [CAI-rich] objects and that those spectra would now initiate another revolution, pointing us to the asteroids that record this earliest stage in the history of our Solar System.

Astronomers Locate Solar System Very Similar To Our Own

Smivs writes "Astronomers from St Andrews University in the UK have discovered a planetary system which looks much like our own. Dr Martin Dominik told BBC news: 'We found a system with two planets that take the roles of Jupiter and Saturn in our Solar System. These two planets have a similar mass ratio and similar orbital radius and a similar orbital period. The newfound planetary system, which orbits the star OGLE-2006-BLG-109L, is more compact than our own and is about five thousand light-years away. The OGLE planets were found using a technique called gravitational micro-lensing, in which light from the faraway planets is bent and magnified by the gravity of a foreground object, in this case a another star.'"

Need an Idea for a Solar System School Project? Build a Scale Model of the Solar System

Everyone seemed to enjoy the answer to my daughter's question, "what's the biggest star?", so I thought I'd give you another insight into space science at the Cain household. A couple of months ago, we built a scaled map of the Solar System. I thought I'd share my process and resources with you, and throw in a few cute pictures of the kids. So come on, let's build a solar system in your neighborhood.

Hot Water Sanitizable USP Quality Reverse Osmosis / EDI Water Purificaiton System

The Mar Cor Purification USPure system is a standard single skid design that includes pretreatment, Reverse Osmosis (RO) & Electrodeionization (EDI) on one integrated skid for fast installation & startup. The validatable system offers a pre-designed space saving layout that is cost effective and assures the reliable production of USP grades of water. The complete system provides for sanitary piping & instrumentation from the RO outlet through to the EDI outlet. The entire system is controlled by a PLC based control system. Two designs are available for sanitization either hot water or chemical. Each system is manufactured under strict Quality Control procedures conforming to ISO 9001:2000. To assure the system is ready for fast startup in your facility, each system is factory acceptance wet tested (FAT) prior to shipment.

Smallest Planet Outside Our Solar System Found

mikkl666 writes "Following the recent story about the discovery of the youngest planet outside our solar system, Spanish researchers now report that they found the smallest exoplanet observed so far. The planet, known as GJ 436c, was found by analyzing distortions in the orbit of another, larger planet, and its radius is only about 50 percent greater than the Earth's. The scientists are confident that their new method will lead to a series of further discoveries: 'I think we are very close, just a few years away, from detecting a planet like Earth.' You can also reference the the original paper online for further details."
