    It is possible the object creating the Tunguska event in Russia 1908 which knocked down 80 million trees over an area about twice the size of New York City was a fragment of a comet or asteroid. The International Asteroid Warning Network 2025 campaign to track Comet 3L/Atlas prepares the worlds observatories for the eventual time when a comet fragment has our number on it.

    Venus and Earth are similar in size, composition, density, and mass. Unfortunately, our sister planet Venus is an example of a place where green house gases have created an extreme situation. Venus's thick carbon dioxide atmosphere has a surface pressure 90 times that of Earth. It would crush a submarine. Additionally, the thick atmospheric blanket holds in the heat causing Venus's surface temperature to be 864 F, hot enough to melt lead.

    Just before noon on September 1st of 1859 Richard Carrington and Richard Hodgson were making sketches of clusters of sunspots when they were nearly blinded by an intense solar flare. 17.6 hours later a geomagnetic storm thought to be caused by a solar coronal mass ejection traveling at some 1,500 miles per second slammed into the magnetic field surrounding our home planet. We missed being hit with a such large coronal mass ejection by only 9 days in July of 2012. Next time we might not be that lucky.
