Discussion and news about planets, exoplanets, and astrobiology
Comparison of "habitable zone" of Kepler 22 system and our solar system (NASA/Kepler) Today sees the announcement that one of the "candidate" planets listed from NASA's Kepler mission back in February is now confirmed, and it's a key one...
What lies beneath such turbulent skies? (NASA/JPL) Gas giant planets are among the most beautiful and awe-inspiring worlds. In our own solar system we've long gazed at Jupiter's extraordinary swirling atmosphere, where stormy circulations like the Great Red Spot persist for centuries...
This is not a comet, it's Curiosity on its way to Mars This, I guarantee, is a view of NASA's Curiosity rover embarking on its 250 day trip to Mars that you may not have seen before...
Mars Pathfinder launches in 1996 Starting this Saturday, a 24 day window of opportunity opens for the launch of NASA's Mars Science Laboratory, now also known as the Curiosity rover.
Greetings Earthling Ok, so this is really entirely for entertainment, and you should check out the excellent all-octopus-all-the-time blog Octopus Chronicles right here at Scientific American for genuine insight, but I couldn't resist posting this video that seems to be on its way to viral fame...
Life, Unbounded is preparing a series of posts on exoplanets, one a day for five days - this planetary menagerie will contain some of the most fascinating, but unsung, "heroes" of exoplanetary science ...
Want to reach for the stars? Sometimes one gets a sinking feeling. Here we are on the cusp of so very many things in science, from finding other Earths, to understanding the extraordinary organisms right under our noses, and even detecting the fundamental particles that help build all that we see...
[Every so often Life, Unbounded allows itself a little more speculative leeway, a little bit of armchair musing, this post is very much in that vein, and yes, it was written on a Mac] Exhibit A Like many scientists of my generation the first time I experienced Steve Jobs was through the almost magical interaction with a mouse, a crisply black and white screen, and Mathematica.As a budding astronomer back in the early 1990's most of my computational needs were taken care of by a hulking great machine called a VAX...
The Ghost of Astrobiology Past The range of topics relevant to astrobiology is pretty staggering - from microbial populations, chemistry, geo-chemistry, geobiology, climate, non-linear systems, solar system exploration, robotics, planetary science, exoplanets, astrophysics, and even cosmology...
Astronomical Clock in Prague (Maros Mraz) Sitting below the swirling leaves and darkening skies of New York today I realized that yet again our planet is roaring up on perihelion at 30 kilometers a second...
