3I/ATLAS Returns with a New Colour
3I/ATLAS has become visible again to Earth-based telescopes and has shown a colour change for the third time, surprising scientists worldwide. This interstellar object now displays a faint bluish tint.
Visibility and Observation
After being hidden from view as it passed behind the Sun near Mars, 3I/ATLAS is back on astronomers' radars. Its changing colours have intrigued researchers and sparked discussions on social media due to its unusual properties.
Colour Changes and Significance
- Originally, 3I/ATLAS appeared red in colour.
- Upon approaching the Sun, it shifted to a deep blue hue, even appearing "distinctly bluer than the sun."
- Now, the object shows a faint blue shade for the third time.
Scientific Understanding
3I/ATLAS defies easy classification. It is known as the third interstellar object observed in our galaxy. By definition, interstellar objects are asteroids or comets that originate outside the solar system, traveling through interstellar space.
"3I/ATLAS' blue colour has raised eyebrows because it somewhat confirmed that it's not a comet."
Continued Research
The unusual characteristics of 3I/ATLAS keep scientists studying its nature, which remains largely mysterious beyond its origin and interstellar classification.
Author's summary: 3I/ATLAS continues to bewilder scientists by changing from red to blue hues multiple times, challenging our understanding of interstellar objects.
