Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:g Abodes - Understanding the structure, dynamics, and chemistry of planetary atmospheres is key to exoplanetary science. It’s sobering to realize that as of now it is still an enormous challenge to model even the atmospheres of planets in our own solar system. Despite great advances, a variety of trickery has to be employed to simulate a swirling maelstrom like the Jovian atmosphere, pretending for example that it has a very different soupiness and energy transport in order to overcome computational demands. Modeling the atmospheres of gas giant exoplanets is even more in its infancy. Nonetheless, an intriguing result a couple of years ago came from Crossfield et al. and their study of how we see the infrared light varying in the planetary system of Upsilon Andromedae. Their Spitzer space telescope phase photometry (light seen as time passes) on Ups And reveals the glow emitted by the innermost, roughly Jupiter sized, planet around this F dwarf star (about 1.3 times the mass of the Sun). See article.g Life - They are tiny, ugly, disease-carrying little blood-suckers that most people have ...
