Sudden catastrophic events are not unknown in Earth’s history. Large craters are evidence of past cosmic impacts. Widespread layers of volcanic ash are a testimony of massive volcanic eruptions. But when did these catastrophes occur and could they have impacted human history? Standard geological models place the largest catastrophic events many eons ago. So long […]
You might think of the asteroid belt between Jupiter and Mars as a assortment of space junk floating randomly in space. There are millions of asteroids of which more than 100,000 have been measured and mapped by astronomers. But analysis of those asteroids has shown that there are groups of asteroids that are related to one another and are referred to family members
Everything has an origin.* Some stories of origins are very simple (eg. the current island of Krakatoa from a volcanic blast recorded in history) while others are much more complex (eg. the Grand Canyon). The study of origins is the study and reconstruction of past events. We have eyewitness accounts of some events from the […]
How long would it take for falling dust to accumulate into a mound 2 1/2 miles tall? Answers in Genesis has commented (Wind, not water, may have built the Martian Mount Sharp) over the weekend on the same research article that I referenced in my post last week (NH Notes: Did Wind and Dust Create a […]
Previously we explored some meteorites that have been found on Earth that are very likely from Mars (Finding Mars on Earth). Only a small percentage of the meteorites found on Earth are from Mars with a few more (over 100) originating from the moon. The remainder presumably come from the far reaches of the […]
Maybe you missed it last week with all the excitement of the pictures from Curiosity and its analysis of the rocks on Mars (See my last post: Curious Geology: Stunning Images Reveal a Complex Mars) but there was another pronouncement of further evidence that watery processes were once active on Mars. Where did this evidence […]
There are millions of asteroids orbiting the solar system most of which are found in the asteroid belt between Mars and Jupiter. Studies of these asteroids, as part of an effort to assess the threats to earth, have allowed us to track and paths, sizes and rotational frequencies of over 1000 asteroids.
The Toba volcano is found near the center of Sumatra, Indonesia. It has been estimated that at least 2800 cubic kilometers of material was thrown into the air during the explosion or series of explosions. To put that in perspective the Krakatoa volcano threw just over 2 cubic kilometers of material into the air some of which circled the globe causing dazzling sunsets in Europe.
As a way of simplifying yesterday’s rambling entry I offer the following comparison of two meteorite impact craters. The first, Victoria Crater, is from Mars and the second, Amguid Crater, is in Algeria, Africa. Let’s compare the features and then ask if they can help us to evaluate the current young earth geology models and […]
How were the planets formed? While young earth creationists appear to be fairly unified in their convictions about the origin of the geological features of the earth, the question of how the planets and the moon came to appear as they do seems to be one for which there is little consensus among YECs other […]
Sometimes you run across an article so ridiculous you can hardly believe you just read it. Such is the case with a chapter of Walter Brown’s book “In the Beginning.” The whole book has significant problems but while I was delving a bit deeper into the origins of meteorites and asteroids and the appearance of […]
Another blog brought to my attention a recent daily news update from ICR that comments on the origins of Mercury. The latter article comments on recently published results of the MESSENGER spacecraft that is now orbiting the planet Mercury (Science abstract). That spacecraft is mapping the surface of Mercury with several instruments including X-ray fluorescence […]
