Gravitational waves leave a detectable mark, physicists say

New research shows that gravitational waves leave behind plenty of 'memories' that could help detect them even after they've passed.

Gravitational forces in protoplanetary disks may push super-Earths close to their stars

more »
Astronomers found that as planets form out of the chaotic churn of gravitational, hydrodynamic -- or, drag -- and magnetic forces and collisions within the dusty, gaseous protoplanetary disk that surrounds a star as a planetary system starts to form, the orbits of these planets eventually get in synch, causing them to slide -- follow the leader-style -- toward the star.

New clues about how ancient galaxies lit up the Universe

more »
NASA's Spitzer Space Telescope has revealed that some of the Universe's earliest galaxies were brighter than expected. The excess light is a by-product of the galaxies releasing incredibly high amounts of ionizing radiation. The finding offers clues to the cause of the Epoch of Reionization, a major cosmic event that transformed the universe from being mostly opaque to the brilliant starscape seen today.
