European researchers are developing miniaturized space propulsion technology that is propellant-free and based on ...

It's got solar flares and massive eruptions that fire fast-moving, charged particles deep into our solar system. "Without that activity, we would not exist. That activity is really necessary for life ...

Space can surprise even those who spend their lives studying it. People often think of our solar system as just a few planets and a bunch of empty space. Yet new observations suggest we have been ...

The discovery doubles the known number of these mysterious celestial objects across our solar system that resemble asteroids but zip through space like comets, albeit without the “tail” comets ...

(NASA/JPL/Space Science Institute) Saturn, by contrast, is practically defined by its extensive rings. It seems likely that, outside the Solar System, rings could be common, given the large number of ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The Christian Science Church, and we’ve always been transparent about that. The Church publishes the ...

“It’s a relic of the environment the solar system was born out of,” Rankin says of the interstellar medium. Within it are energetic atomic fragments called galactic cosmic rays, as well as ...

Solar panels can save money on electric bills, but a solar panel system requires a steep upfront investment — $30,000 for the average system including installation ...

The work joins other studies that have proposed interstellar flybys to explain eccentricities in the orbits of certain objects in the solar system. The solar system is approximately 4.6 billion ...

The orbits of the planets around the Sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since ...

Solar inverters are a necessary but often forgotten part of a home solar panel system since they convert sunlight into usable electricity for your home appliances. Without a solar inverter ...

The residential clean energy credit can help you to recoup as much as 30% of the cost of solar panels. Many, or all, of the products featured on this page are from our advertising partners who ...
