NASA | Coming Soon: Closest Approach

The video discusses a dynamic system involving a pulsar orbiting a star, highlighting its unique long orbit and acceleration over the past decade. As the pulsar passes close to its binary companion, significant gamma ray emissions are expected, which will be observed using Fermi's tools. The video emphasizes the need for extensive data collection and system commands for operation.

What is unique about the pulsar's orbit mentioned in the video?

• It is the shortest orbit ever recorded.

• It is the fastest orbit ever observed.

• It is the longest orbit ever observed.

• It is the most elliptical orbit ever recorded.

What is notable about the binary companion star in the system?

• It is the oldest star in the galaxy.

• It is the dimmest star in the galaxy.

• It is the largest star in the galaxy.

• It is one of the brightest stars in the galaxy.

How long has the pulsar been accelerating?

• 5 years

• 10 years

• 15 years

• 20 years

What is expected to happen when the pulsar passes through the companion star's disc?

• A massive solar flare will occur.

• The pulsar will stop accelerating.

• A black hole will form.

• Significant gamma ray emissions will be observed.

Which instrument will be used to observe the gamma ray emissions?

• Chandra X-ray Observatory

• Hubble Space Telescope

• Fermi Gamma-ray Space Telescope

• James Webb Space Telescope
