Hidden rift valley discovered beneath West Antarctica reveals new insight into accelerating Scientists have discovered a one mile deep rift valley hidden beneath the ice in West Antarctica, which they believe is contributing to ice loss from this part of the continent. Experts from the Universi...
Tidy close-match star system holds planetary pinball clue A trio of planets orbiting a sun-like star has the most similar layout to our solar system yet seen. The discovery supports the idea that planets emerge from relatively flat discs of material encircling stars and, at first, orbit neatly in t...

A Dew Shield is a hollow plastic, plastic/foam, or aluminium cylinder that slides onto the front of your scope. It has the advantage of blocking stray light (e.g. from your neighbour's porch light) and adding weight to the front of the scope which helps balance heavy items mounted on the scope's rear...
New clues to the early Solar System from ancient meteorites In order to understand Earth's earliest history--its formation from Solar System material into the present-day layering of metal core and mantle, and crust--scientists look to meteorites. New research from a team including Carnegie'...
