Why Shouldn’t You Touch a Meteor?
Meteorites, fragments of asteroids or comets that have fallen to Earth, are a fascinating and valuable scientific resource. However, despite their allure, it’s essential to exercise caution when handling meteorites, as they can be fragile and susceptible to damage. In this article, we’ll explore the reasons why it’s crucial to avoid touching meteorites and provide guidelines for handling these celestial bodies safely.
Oils and Microbes from Your Skin
One of the primary reasons why you shouldn’t touch a meteorite is that the oils and microbes from your skin can contaminate the surface of the meteorite. Fusion crust, the thin layer of melted rock that forms on the surface of meteorites during their descent through the Earth’s atmosphere, can be damaged or destroyed by human contact. This not only compromises the scientific value of the meteorite but also reduces its monetary value, as collectors and researchers are willing to pay a premium for uncontaminated samples.
Chemical Reactions and Rust
Meteorites are made up of a variety of minerals, some of which are reactive to human skin oils and sweat. Chemical reactions can occur when these minerals come into contact with the natural oils and acids present on human skin, leading to the formation of rust or other substances that can alter the meteorite’s composition. This can be particularly problematic for meteorites that are already fragile or prone to oxidation.
Contamination and Damage
When you touch a meteorite, you’re not just transferring oils and microbes to its surface – you’re also introducing potential contaminants that can damage the meteorite’s structure. Fingerprints, sweat, and dirt can all leave behind residue that can compromise the meteorite’s integrity, making it difficult or impossible to study or preserve.
Preservation and Storage
Meteorites are highly valuable scientific resources, and it’s essential to preserve them in their natural state to ensure their continued value. Proper storage and handling are crucial to maintaining the integrity of meteorites, and this includes avoiding contact with human skin and oils.
Handling Meteorites Safely
If you do need to handle a meteorite, there are some precautions you can take to minimize the risk of contamination and damage:
• Wear gloves: Latex or nitrile gloves can help prevent oils and microbes from transferring to the meteorite.
• Use a soft cloth: When handling meteorites, use a soft, lint-free cloth to prevent scratching or damaging the surface.
• Avoid touching the surface: Try to handle meteorites by the edges or through a protective sleeve to minimize contact with the surface.
• Clean and store carefully: Clean meteorites with a soft brush and mild soap, and store them in a cool, dry place to prevent oxidation and contamination.
Conclusion
Meteorites are fascinating and valuable scientific resources, but they require careful handling and preservation to maintain their integrity. By understanding the risks associated with touching meteorites, including contamination, chemical reactions, and damage, we can take steps to ensure their continued value and preservation. Remember to handle meteorites safely, using gloves, soft cloths, and protective sleeves to minimize contact with the surface. By doing so, we can protect these celestial bodies for future generations of scientists and collectors.
