The most mysterious object ever detected in our solar system.

In 2017, Pan-STARRS telescope discovered 'Oumuamua—the first confirmed interstellar object. It was already leaving when we found it, tumbling through space at 196,000 mph.

Then something strange happened: it accelerated. Objects don't just speed up in space without reason. Comets accelerate when they release gas (outgassing), but 'Oumuamua showed no gas emissions.

Harvard astronomer Avi Loeb proposed a controversial explanation: it could be an alien light sail—a thin, artificial structure propelled by starlight. Other scientists suggested natural explanations (hydrogen ice, nitrogen ice), but none fit perfectly.

We'll never know the truth. 'Oumuamua is now beyond our reach, traveling into interstellar space.

🌌 'Oumuamua's complete story & the alien hypothesis:    • 3I/ATLAS: NASA's New Interstellar Comet | ...  

What made it accelerate?
Unknown. Possibilities include:
Outgassing we couldn't detect
Reflective surface acting as light sail
Unusual composition (hydrogen or nitrogen ice)
Artificial origin (most controversial)

Why couldn't we study it better?
We discovered it AFTER it passed the Sun. By the time we realized it was interstellar, it was already leaving. We had weeks to observe before it became too faint.

Will we see another?
Yes. 2I/Borisov visited in 2019, 3I/ATLAS in 2024. Vera Rubin Observatory will detect many more.

'Oumuamua remains one of astronomy's most debated objects.
