This Hot Jupiter Is Leaking Metal! SciShow News

The video explores the study of hot Jupiters, focusing on WASP-121b, a planet shedding metal gas due to its extreme heat. This phenomenon provides insights into planetary evolution. Additionally, a new 3D map of the Milky Way reveals its warped structure, using data from Cepheid stars to understand the galaxy's shape and distance measurements.

What makes hot Jupiters easier to detect compared to other exoplanets?

• They have a solid surface.

• They are smaller and cooler.

• They orbit far from their host stars.

• They are large and orbit close to their stars.

What is unique about the planet WASP-121b?

• It is colder than any other exoplanet.

• It orbits a G-type star.

• It has metal gas escaping its atmosphere.

• It is the smallest known exoplanet.

How does WASP-121b's proximity to its star affect its atmosphere?

• It makes the atmosphere more stable.

• It heats the atmosphere, causing it to expand.

• It cools down the atmosphere.

• It causes the atmosphere to shrink.

What method is used to map the Milky Way using Cepheid stars?

• Measuring their temperature.

• Observing their color.

• Tracking their brightness variation.

• Calculating their mass.

What did the new 3D map reveal about the Milky Way?

• It is shaped like a cube.

• It is perfectly flat.

• It is smaller than previously thought.

• It has a warped, S-shaped disk.

What might cause the Milky Way's disk to warp?

• The influence of solar winds.

• The presence of a black hole at its center.

• Gravitational interactions with nearby galaxies.

• The absence of dark matter.

How does the Milky Way's shape compare to other spiral galaxies?

• All spiral galaxies are perfectly flat.

• Only elliptical galaxies have warped disks.

• Most spiral galaxies, including Andromeda, have warped disks.

• It is the only galaxy with a warped disk.
