The Sun rising above the Arctic plain (H. D. Nygren, NOAA Corps.) As our spinning globe of rock and metal tracks its steady path around the Sun, we find ourselves crossing once again through the winter solstice, the point at which Earth's northern pole is pointed as far from our fierce stellar parent as it can be (this year at a coordinated universal time of 5.30 am on December the 22nd, almost the same as 5.30 am Greenwich Mean Time).
A strange chemical reaction Imagine, if you will, a planet with atmosphere, oceans, rocks and life. On this planet, most chemical reactions are either slow and geophysical, or quick and biological but very localized.
Warning: Exoplanets may appear less massive than they really are (images used: Eysteinn Guðni Guðnason and NASA/Kepler) Exoplanets can be confusing things.
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.
