TED: The story of 'Oumuamua, the first visitor from another star system | Karen J. Meech

'Oumuamua, an interstellar object, was discovered by the Pan-STARRS telescope in 2017. It was named in honor of Hawaiian culture and is significant for its insights into the solar system's past. Observing 'Oumuamua posed challenges due to its rapid movement and fading brightness. Its unique shape and rotation suggest a complex origin. While its exact composition remains uncertain, it reflects red light similar to some comets. Future technologies may help detect such objects earlier, offering more opportunities for study.

How did the brightness of 'Oumuamua vary, and what does this indicate about its shape?

What was the significance of the Hubble Space Telescope's observations of 'Oumuamua?

What experiments were proposed to investigate whether 'Oumuamua could be artificial?

Discuss the implications of 'Oumuamua's visit for our understanding of the solar system.
