Some of the most interesting exoplanets discovered so far are the “super-Earths,” rocky worlds which are significantly larger and more massive than Earth but still smaller than the ice giants such as Uranus or Neptune. Since they are not present in our own Solar System, their existence elsewhere can provide valuable information about planetary formation … Read more
Saturn’s moon Titan is one of the murkiest places in the Solar System; its thick smog-like hydrocarbon haze in the upper atmosphere shrouds the entire moon, much like Venus’ perpetual cloud cover. Titan’s surface is completely hidden by this orange-ish haze, making it look rather bland and uninteresting. This unique environment may provide valuable clues … Read more
There is some good news for planet-hunters this week: The proposed K2 mission extension for the Kepler Space Telescope has been been approved by NASA. The approval, based on a recommendation from the agency’s 2014 Senior Review, means that the Kepler mission will have at least two more years to continue its search for exoplanets, … Read more
There was more exciting exoplanet news this week from the Kepler mission: the space telescope has confirmed 715 new exoplanets! This brings the current total number of such worlds to 1,766, of which 961 have been found by Kepler. There are still also 3,601 other Kepler planetary candidates awaiting confirmation.
Meteors flashing across the sky are a common sight here on Earth, but of course they are not limited to only our planet; these bits of rocky debris, smaller pieces of asteroids and comets known as meteoroids, can be found just about everywhere in the solar system (becoming meteors when entering and burning up in … Read more
For any future astronauts who land on Mars, there is one piece of advice that shouldn’t even need to be said: keep your helmet on! Mars has an atmosphere, like Earth, but it is much thinner than ours (and mostly carbon dioxide), and so is unbreathable by humans. However, evidence has continued to grow that … Read more
You may be familiar with the phrase “follow the water” when it comes to the search for life on Mars, and for good reason – any place on Earth where there is liquid water, there is life. So, logically, the best places to look for evidence of past or present life on Mars would be … Read more
