A Titan Discovery

NASA scientists are investigating the potential for life on Saturn's moon Titan, which has seas of liquid methane. Earth-like cell membranes cannot form there, but simulations suggest acrylonitrile could create stable membranes. NASA Goddard detected this molecule in Titan's atmosphere, indicating it might reach the surface. This discovery brings us closer to understanding life's possibilities in our solar system.

What makes Titan unique in the solar system compared to other celestial bodies?

• It is the largest moon of Jupiter.

• It has an atmosphere similar to Earth.

• It has liquid seas of methane.

• It has liquid seas of water.

Why can't Earth-like cell membranes form on Titan?

• The temperature is too high.

• There is no atmosphere.

• The liquid on Titan is methane, not water.

• There is too much sunlight.

Which molecule has been identified as a candidate for forming cell-like membranes on Titan?

• Carbon Dioxide

• Methane

• Water

• Acrylonitrile

What tool did NASA use to detect acrylonitrile in Titan's atmosphere?

• Voyager 1

• ALMA Observatory

• James Webb Space Telescope

• Hubble Space Telescope

How might acrylonitrile reach Titan's surface?

• Through volcanic eruptions

• Via meteorite impacts

• By solar winds

• Through rain
