The comet could be older than our solar system. The comet is also distinct because nickel vapor was detected in the gas surrounding it.

CNN’s Tom Foreman breaks down what we know about the interstellar comet that originated outside our solar system.

Interstellar comet 3I/ATLAS baffles scientists, brightening 7x faster and turning blue. A Harvard expert suggests its strange path is a 'possible hint of design'.

Harvard Professor Avi Loeb discusses the mystery surrounding the 31/ATLAS comet and explains his argument that it has a 40% chance of being alien technology.

Physicist Michio Kaku is warning about the AI-generated deepfakes, which exploit his image to push the idea the comet '3I/ATLAS' is an alien spacecraft that poses a potential threat.

Almost 50 years after the WOW! signal stunned astronomers in Ohio, 3I/Atlas reappears in the same sky region, raising questions about extraterrestrial activ

They also noted that iron was not detected alongside the nickel, an uncommon pattern in comets. Rahatgaonkar and Seligman suggested that the nickel may be locked in molecules that break apart easily under sunlight, releasing the metal at low temperatures.

Comet Lemmon can be found west of the Big Dipper, beyond bright star Arcturus, while Comet SWAN is moving towards Saturn, and is presently beneath Altair, the bright star at the tip of the famous Summer Triangle. The best time to look is 90 minutes after sunset.
