NASA | Fermi Detects First Gamma-ray Pulsar in Another Galaxy

The video explores the Milky Way and the Tarantula Nebula, focusing on gamma ray emissions. It highlights the discovery of the gamma ray pulsar J0540, which challenges previous beliefs about gamma ray sources. The Fermi Gamma Ray Space Telescope's advancements have improved gamma ray detection, revealing new insights into cosmic rays and their behavior in star-forming regions. This discovery suggests a need to revisit our understanding of cosmic ray production and movement.

What is the Tarantula Nebula known for in the context of gamma rays?

• Being the largest nebula in the universe

• Having the most stars in the Milky Way

• Producing the most gamma rays in the LMC

• Being the closest nebula to Earth

What was the initial belief about the source of gamma rays in the Tarantula Nebula?

• They were from the sun

• They were from black holes

• They were a byproduct of star formation

• They were from alien technology

Which pulsar was discovered to be the most luminous gamma-ray pulsar?

• Crab Nebula Pulsar

• Pulsar J0540-6919

• Pulsar J0537-6910

• Vela Pulsar

What was a significant finding about the gamma-ray emissions from the Tarantula Nebula?

• They were mostly from a single pulsar

• They were due to solar flares

• They were caused by a supernova

• They were from a nearby black hole

How did Fermi's Large Area Telescope improve its ability to detect gamma rays over time?

• By increasing its size

• By collecting more gamma rays and improving data analysis

• By moving closer to the sources

• By using a new type of lens
