NASA’s Curiosity rover has discovered evidence that an ancient Martian lake had the right chemical ingredients that could have sustained microbial life forms for long periods of time – and that these habitable conditions persisted on the Red Planet until a more recent epoch than previously thought.
One of the best annual meteor showers occurs this coming weekend.
What is the coldest place on Earth? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night.
Oceans are such vast and often overwhelming subjects. Because of their sheer scope in size, the discussions that are often had regarding seas and different discoveries within it, can be both mind boggling and intriguing. There are enormous mysteries in the depths of the oceans. While some of these phenomena have been explained by analysts and experts, there are still some interesting occurrences underwater that can’t really be rationalized. Sailors from all around the world have witnessed and experienced a variety of incredible ocean phenomena. Below is a list of the top 10.
Could Comet ISON possibly still be alive? The latest high-resolution images available from the STEREO spacecraft are still showing some remains of the comet, although each day seems to show less and less activity.
What the heck is that giant exoplanet doing so far away from its star? Astronomers are still trying to figure out the curious case of HD 106906 b, a newly found gas giant that orbits at an astounding 650 astronomical units or Earth-sun distances from its host star. For comparison, that’s more than 20 times farther from its star than Neptune is from the sun.
This is an artist’s conception of a young planet in a distant orbit around its host star. (Photo: NASA/JPL-Caltech) A giant planet that has been found orbiting its star at 650 times the average Earth-Sun distance has stirred immense confusion in the minds of US astronomers, making them question planet formation theories. The planet – […]
Gravity. The average person probably doesn’t think about it on a daily basis, but yet gravity affects our every move. Because of gravity, we fall down (not up), objects crash to the floor, and we don’t go flying off into space when we jump in the air. The old adage, “everything that goes up must come down” makes perfect sense to everyone because from the day we are born, we are seemingly bound to Earth’s surface due to this all-pervasive invisible force.
