    About 12 billion years ago, an enormous galaxy was home to 300+ billion suns...but suns "quickly" stopped forming there. The scientists used spectroscopic observations to measure this galaxy (XMM-2599) and determine its distance.

    Sebastian Otero (AAVSO staffer) used NASA's TESS data to determine that Theta Carinae is the brightest heartbeat star known thus far. It's the central star of the southern open cluster IC 2602, visible with the naked eye at V= 2.74. Below: tet Car light curve of NASA'S TESS data
