Mercury, the closest planet to the Sun, has been heavily bombarded by meteorites throughout its history, similar to other rocky planets in our solar system. Its surface is covered with impact craters, some of which are quite large and ancient. Due to Mercury’s lack of a significant atmosphere, incoming meteorites do not burn up, resulting in frequent and intense impacts. Notable examples include:

Caloris Basin: One of the largest known impact craters in the solar system, the Caloris Basin spans about 1,550 kilometers (960 miles). It was likely formed by an asteroid impact during Mercury's early history.

Kuiper Crater: A relatively small but well-preserved crater, named after the astronomer Gerard Kuiper, is about 60 kilometers (37 miles) in diameter.

Hokusai Crater: Another large crater on Mercury, measuring 114 kilometers (71 miles) in diameter, with bright rays of ejected material extending over much of the planet.

Mercury's surface is thought to have experienced more impacts than Earth's, Mars', or Venus' due to its proximity to the Sun, which pulls in more meteoroids and comets. These impacts have significantly shaped the planet's geological history and surface evolution.

The Outer Solar System Supplied a Surprising Amount of Earth’s Water
In a recent study published in Science, a team of researchers at Imperial College London examined 18 meteorites containing the volatile element zinc to help determine their origin, as it has been long hypothesized that Earth’s volatiles materials, including water, were derived from asteroids closer to our home planet. However, their results potentially indicate a … Continue reading ""

MAKING SPIDER SILK
Bible Study / Daily Devotional
Daily Devotions
Average reading time is about 5 and a half minutes
AN AMAZING FACT: One of the most amazing materials in nature is the light, flexible, yet incredibly strong compound spiders use to catch unsuspecting insects. It’s spider silk. Pound for pound, the threads produced by these little arachnids can hold more weight than the most sophisticated manufactured materials. The silk in a spider web is an extremely strong substance that has a tensile strength of 300,000 pounds per square inch and is both stronger and lighter than compounds based on steel.

For a long time people have known about the impressive properties of spider silk, and some have dreamed of being able to create it, perhaps the way that the ancient Chinese learned to produce silk from silkworms. But unlike the gentle silkworm, spiders are aggressive, territorial, and not easily domesticated. Up until now all attempts to synthesize spider silk have failed, but a new venture involving gene-splicing is showing considerable promise.

A Canadian company, Nexia Biotechnologies, appears on the verge of manufacturing a substance similar to spider silk through a surprising method, using the milk of goats. Researchers put the spider silk gene into milk animals, since there are close anatomical similarities between the silk-producing glands of spiders and the milk-producing glands of these mammals. The scientists spliced the spider silk gene into cells taken from the mammary glands of goats. The silk genes worked with amazing efficiency in the mammary cells, and Nexia scientists were soon producing high-quality spider silk.

Now the challenge will be to mass breed these transgenic goats and extract the pure silk protein from the milk and spin it into fabric. If the new stock of genetically altered goats produce as expected, Nexia will have the beginnings of a spider-silk dairy. The product, called “BioSteel,” may soon be used for a variety of applications, from medical sutures to artificial tendons or ligaments. It could be used to create lighter and stronger bulletproof vests, and even for the coatings of space stations to protect them from micro-meteorites.

It’s interesting to consider how many of man’s inventions have been plagiarized from the amazing creatures God has designed. The most amazing fact is that many people think all these wonders of nature have evolved by chance!
