More space news and info at: coconutsciencelab.com - just 114 miles from the newly-found Hiawatha impact crater under the ice of northwest Greenland, lies a possible second impact crater.

The 22-mile wide feature would be the second crater found under an ice sheet, and if confirmed, would be the 22nd-largest crater on Earth.

The second crater looks to be much older than Hiawatha, with features that are significantly more eroded, and it contains older ice than its neighbor.

Please rate and comment, thanks!
