New Results from Philae, and the Perseids Meteor Shower!

The video discusses Comet 67P's approach to the sun and the findings from the Philae lander, which faced landing challenges but discovered complex organic molecules. It also covers Comet Swift-Tuttle's orbit and its role in the Perseids meteor shower, highlighting the potential for future close encounters with Earth.

What was the main challenge faced by the Philae lander during its mission on comet 67P?

• It failed to detach from the Rosetta orbiter.

• It bounced and landed in a shaded area, limiting its power supply.

• It was destroyed upon impact with the comet's surface.

• It was unable to collect any data due to a malfunction.

What significant discovery did Philae make about the surface of comet 67P?

• The surface is covered with metallic compounds.

• The surface has a soft layer over a hard layer, with organic molecules present.

• The surface is smooth and featureless.

• The surface is entirely made of ice.

What unusual compounds did Philae discover on comet 67P?

• Complex carbon-containing compounds

• Simple sugars

• Radioactive isotopes

• Heavy metals

What is the significance of Comet Swift-Tuttle in relation to meteor showers?

• It causes the Leonids meteor shower.

• It is responsible for the Perseids meteor shower.

• It has no connection to meteor showers.

• It causes meteor showers only in the Southern Hemisphere.

What was the concern regarding Comet Swift-Tuttle's orbit in the 1990s?

• It was moving away from the solar system.

• It could potentially collide with Earth in 2126.

• It might collide with Mars.

• It was losing its tail.
