Key Takeaways
- Interstellar comet 3I/ATLAS is behaving unexpectedly near the Sun
- It changed color, brightness, speed, and showed non-gravitational acceleration
- Scientists are puzzled by the absence of a tail and massive gas/dust cloud
- The object is currently visible from Earth through telescopes
The interstellar comet 3I/ATLAS continues to baffle scientists with its unusual behavior near the Sun. The object has demonstrated unexpected changes in color, brightness, and speed, along with non-gravitational acceleration that has researchers questioning their understanding of interstellar visitors.
Missing Tail and Gas Cloud Puzzle Scientists
Fresh images taken after 3I/ATLAS emerged from the Sun’s glare reveal a distinct lack of a cometary tail. Harvard scientist Avi Loeb has flagged this as a significant anomaly. According to Loeb, the absence of a massive cloud of gas and dust around 3I/ATLAS could reveal the object’s true nature.
“It needs to have a huge cloud of gas and dust around it if it is a comet,” Loeb stated. Latest observations from the R. Naves Observatory and Virtual Telescope Project confirm the missing tail, contrasting sharply with typical comets like solar system’s comet Lemmon which displays a lengthy tail.
Unexpected Speed Changes Near Sun
NASA data indicates 3I/ATLAS suddenly accelerated near the Sun, reaching speeds of approximately 244,620 km/hr. While NASA initially attributed this speed increase to the Sun’s gravity, scientists now question this explanation as they try to understand why the object moved away from the Sun in unexpected ways.
The 5-Billion-Ton Mystery
Scientists expected to see a massive cloud of dust and gas around 3I/ATLAS weighing approximately 5 billion tons, based on calculations of how much mass the object should have lost near the Sun. However, no such cloud has been detected, adding to the mystery surrounding this interstellar visitor.
How to Spot 3I/ATLAS
The interstellar comet is currently visible from Earth through binoculars and telescopes. Astronomy enthusiasts can use tracking tools like The Sky Live tracker to locate the exact position of this alien visitor before it vanishes from view.
