Observations of dim galaxies lensed by foreground clusters provides a way of measuring the progression of reionization.
Well, let’s have a drink and see if that helps us figure things out.
NASA’s TESS spacecraft has launched! Today’s paper predicts how many exoplanets it will find.
Statistical confirmation of long-period, low SNR candidates should be taken with a grain of salt. The reliability is too low to confirm individual systems without followup observations and the 99% confidence validation of Kepler-452b is likely closer to 90%.
Oscillations at the center of the Sun have been observed for the very first time. What do they mean for the rotation of the Sun?
The light from a star is not constant, it varies as the layers of hot material move back and forth, clump and disperse. Most of these vibrations are visible, detectable, and well understood. But some bizarre new vibration is happening in stars, for which we have no clear path to an explanation.
