Are planets still being formed?

The video discusses the discovery of Earth-like planets orbiting a pulsar neutron star, a remnant of a supernova explosion. These planets were detected using precise Doppler shift measurements. The formation of these planets post-explosion suggests that planet formation is a robust process, indicating a vast number of planets in the Milky Way galaxy.

What is a pulsar neutron star?

• A star that has exploded in a supernova and is rapidly rotating.

• A star that is similar to our Sun.

• A star that is in the process of forming.

• A star that has not yet exhausted its fuel.

How did Alex Volchen detect the planets around the pulsar?

• By using infrared telescopes.

• By detecting gravitational waves.

• By measuring the Doppler shift in the neutron star's beam.

• By observing the brightness of the star.

What does the existence of planets around a pulsar suggest about planet formation?

• Planets cannot survive a supernova explosion.

• Planet formation is a robust process that can occur even after a supernova.

• Planets can only form around stars like our Sun.

• Planet formation is a rare process.

What happened to any planets that existed before the star became a pulsar?

• They remained unchanged.

• They were incinerated and swept away.

• They became part of the star's core.

• They were absorbed by the star.

What does the discovery of planets around pulsars imply about the number of planets in the Milky Way?

• The number of planets is equal to the number of stars.

• Planets are only found around pulsars.

• There are fewer planets than stars.

• There are likely more planets than stars in the Milky Way.
