Post navigation NASA scientists have discovered a large mass buried beneath the surface of the moon. It is estimated to be around 1.5 miles deep and is composed of a material denser than expected that is also emitting heat. This could help scientists further unlock the mysteries of the moon’s formation and internal structure. Heavy rains caused flash flooding throughout the Northeast on Tuesday morning. This is the result of multiple storms that are happening at once. There has also been additional flooding caused by overflowing rivers and streams.
