Oh, No!

It’s not just the globe; it is the whole universe!

Astronomers at Ohio State University have taken the mean temperature of cosmic gas at different distances and ages, and found that it’s roughly 10 times hotter today than it was 10 billion years ago.

Here’s the link at New Atlas, but I am sure it is (fill-in-the-blank’s) fault.

Why was I looking up?

May 7, 2012

On May 5 the full moon achieved it closest approach to the earth at midnight.  This has been called a super moon and is explained here.

I drove to a high spot with an unobstructed view and gazed toward what was (I hoped) east.  And  soon a ghostly white and very large full moon rose up from the horizon.  I was surprised at how fast the moon rose – actually a function of how fast the earth is spinning.  It was pretty impressive.  I was not as impressed by my photos of the event, so I found the one above which is better.

I actually went outside later that night (3:00 am) and the moon was so bright that it made the trees cast very distinct shadows on the ground.

I read that the tides are higher at these times, as well, but living on Lake Erie with a tidal range of inches, it did not make much difference.

Here are the figures: the distance between the Moon and the Earth varies from around 356,400 km (at perigee) to 406,700 km (at apogee.)
