The way a star flickers can shed light on the strength of gravity's pull on its surface, researchers say. And discovering more about a star's pull can yield key insights on its evolutionary state and on any planets that might orbit it, scientists added.

Galaxies no longer producing stars (quenched galaxies) have long puzzled astronomers with how they grow. Now Hubble Space Telescope and European Southern Observatory's VISTA have shown that larger galaxies stopped producing stars later in life.
01 August 2013, 09:01 AM ET
New observations from NASA's Hubble Space Telescope have helped astronomers solve a longstanding mystery about galaxy evolution. It turns out that ancient galaxies stopped forming stars at a smaller size than their younger cousins did.
