Observations of ten different exoplanet atmospheres could be the very beginning of a modern-day exoplanet HR diagram.
Today’s paper explores the galactic homes of superluminous supernovae — some of the brightest explosions in our universe.
Today we review a study searching for a way to measure the ages of stars in a galaxy. The quantity of long period variable stars gives information about the life cycle of a galaxy, and the authors explain that with their new technique it is possible to take the “pulse” of a galaxy.
What were the first galaxies in the Universe like? Current observations can only access a handful of these ancients. However, a new simulation has synthesized millions to better understand the galaxies of 13 billion years ago.
Although this planet is far from habitable, scientists have confirmed the presence of water vapor in the atmosphere of the WASP-12 system. What does this infer about its planetary atmosphere? Is this in agreement with other studies? The story is not as black and white as we might have thought.
Over the past decade the study of planetary debris at white dwarfs has become an increasingly exciting area. Observations of this debris have allowed us to make unique discoveries about the chemical composition of extrasolar rocky planets, as well as revealing the endpoints of the evolution of planetary systems very similar to our own…
