Questions: Which of the following statements about the Crab Nebula is FALSE? Please select the best choice from the available options. the neutron star inside shows clear evidence of slowing down just a little bit in its rotation we can detect a pulsar inside the nebula using both radio waves and visible light the nebula still puts out more energy (at all wavelengths) than 100,000 Suns it is the remnant of a supernova explosion first seen on Earth in 1054 AD inside, there are a number of newly formed massive stars (O and B type stars)

Solution Steps

We need to determine which statement about the Crab Nebula is false. The statements are:

1. The neutron star inside shows clear evidence of slowing down just a little bit in its rotation.
2. We can detect a pulsar inside the nebula using both radio waves and visible light.
3. The nebula still puts out more energy (at all wavelengths) than 100,000 Suns.
4. It is the remnant of a supernova explosion first seen on Earth in 1054 AD.
5. Inside, there are a number of newly formed massive stars (O and B type stars).

1. Neutron Star Rotation: The neutron star (pulsar) inside the Crab Nebula is known to be slowing down in its rotation over time. This is a well-documented phenomenon.
2. Pulsar Detection: The Crab Pulsar can indeed be detected using both radio waves and visible light, among other wavelengths.
3. Energy Output: The Crab Nebula emits a tremendous amount of energy, more than 100,000 times that of the Sun, across all wavelengths.
4. Supernova Remnant: The Crab Nebula is the remnant of a supernova explosion that was observed on Earth in 1054 AD.
5. Newly Formed Massive Stars: The Crab Nebula is not known to contain newly formed massive stars (O and B type stars). It is primarily composed of the remnants of the supernova explosion and the pulsar.
