Irradiated Comet 3I/ATLAS: Green Glow and Hidden Tail
Here’s a breakdown of the facts presented in the text, focusing on the key details about comet 3I/ATLAS:
What is Comet 3I/ATLAS?
* It’s an interstellar comet, meaning it originated outside our solar system.
* It has a long tail (as shown in the provided image).
Recent Observations & Findings:
* Gemini South Observatory (Chile): A photo was taken in July showing the comet.
* Lowell Discovery Telescope (Earth): Qicheng Zhang observed the comet on October 31st (Halloween) and again recently.
* Diatomic Carbon Image: zhang released an image showing what the comet might look like to the naked eye.
* Radiation Crust: Preliminary research suggests the comet has developed a thick crust due to billions of years of exposure to space radiation.This crust could obscure its original composition and make it harder to determine its origins.
* Movement: The comet is currently moving northward from our outlook and is visible in the early morning as it rises above the horizon.
significance:
* Studying 3I/ATLAS could provide insights into other star systems, but the radiation crust may complicate this.
