That Starry Night Sky? It’s Full of Eclipses

That Starry Night Sky? It’s Full of Eclipses

And astronomers can, in a sense, “see” eclipses among other systems of planets orbiting their parent stars. In this case, the eclipse is a tiny drop in starlight as a planet, from our point of view, crosses the face of its star. That crossing, called a transit, can register on sensitive light sensors attached to … Read more

Discovery Alert: a Long Year for a ‘Cold Saturn’

The decades-long hunt for exoplanets – planets around other stars – has so far yielded more than 5,500 that are confirmed to be scattered across the Milky Way, which likely contains hundreds of billions. But the prevailing detection method turns up relatively few “long period” planets, those with years lasting 50 days or more. This … Read more

Discovery Alert: Glowing Cloud Points to a Cosmic Collision – NASA Science

Even within our own solar system, scientists have seen evidence of giant, planetary collisions from long ago. Remaining clues like Uranus’ tilt and the existence of Earth’s moon point to times in our distant history when the planets in our stellar neighborhood slammed together, forever changing their shape and place in orbit. Scientists looking outside … Read more
