CAPE CANAVERAL, Fla. — A pair of European satellites have created the first artificial solar eclipses by flying in precise and fancy formation, providing hours of on-demand totality for scientists.

Every 18 months or so, the Moon perfectly aligns with our view of the Sun, obscuring the face of the star. Although it lasts for a few minutes, a total solar eclipse is the perfect opportunity for ...

A pair of spacecraft just launched to create hundreds of artificial solar eclipses in orbit. The European Space Agency mission, called Proba-3, will allow scientists “to see an eclipse on demand,” as ...
