Hot Jupiters probably no longer there and intensely bright star outshines galaxy

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - An intensely bright star between Earth and a distant galaxy steals the spotlight in a new image from the Hubble Space Telescope that was originally aimed at the galaxy in the background. See article.
g Abodes - New research indicates that most of the “hot Jupiter” planets that have been discovered beyond our solar system were likely destroyed by their stars long ago. The study provides new insight into the formation and evolution of planetary systems and will help astrobiologists determine where to search for habitable, extrasolar worlds. See article.
g Life - We have a long way to go in understanding climate change, but we do know that complex interactions between plants and the climate of Earth go well beyond the Carbon Cycle. Studying the links between life and climate will aid in understanding life's future on Earth. See article.
g Intelligence - As children in Western cultures grow, they learn to place numbers on a mental number line, with smaller numbers to the left and spaced further apart than the larger numbers on the right. Then the number line changes to become more linear, with small and large numbers the same distance apart. Children whose number line has made this change are better at remembering numbers, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. See article.
g Message - In the absence of knowledge of physical and cultural clues, communication between two species can be almost impossible — almost. See article. This article is from 1999.
