Magnetar Trivia Questions

How much do you really know about Magnetar? Below are 8 true or false statements. Click each one to reveal the answer and explanation.

1.

A magnetar's surface can experience starquakes that crack its crust, releasing huge energy bursts.

Click to reveal answer ›

Easy
✓ TRUE

Starquakes occur when the intense magnetic field stresses the crust, causing fractures that unleash powerful X-ray and gamma-ray flares.

2.

Magnetars can emit bursts of energy that outshine entire galaxies in a split second.

Click to reveal answer ›

Medium
✓ TRUE

Magnetar flares release gamma rays brighter than a galaxy for milliseconds, making them among the most energetic events in space.

3.

If a magnetar passed within 100,000 miles of Earth, it would wipe out all life by crushing our planet.

Click to reveal answer ›

Medium
✗ FALSE

The magnetic field would disrupt electronics and cause auroras, but the crushing effect is negligible at that distance—tidal forces are the real threat.

4.

Magnetars are a type of neutron star with the most powerful magnetic fields in the universe.

Click to reveal answer ›

Medium
✓ TRUE

Magnetars are indeed neutron stars with magnetic fields trillions of times stronger than Earth's, the most intense known.

5.

Magnetars spin faster than any other known astronomical object.

Click to reveal answer ›

Medium
✗ FALSE

Pulsars can spin hundreds of times per second, while magnetars typically rotate once every few seconds—much slower.

6.

A magnetar's magnetic field is so intense it can warp the shape of atoms into thin rods.

Click to reveal answer ›

Hard
✓ TRUE

Atoms under a magnetar's field become compressed into cylindrical shapes, a phenomenon called 'magnetic deformation.'

7.

All neutron stars eventually become magnetars as they age.

Click to reveal answer ›

Hard
✗ FALSE

Only about 10% of neutron stars become magnetars; the rest remain ordinary pulsars or cool into dead stars.

8.

A magnetar's magnetic field can strip information from a credit card from halfway across the galaxy.

Click to reveal answer ›

Hard
✗ FALSE

While incredibly strong, magnetic fields weaken with distance; a magnetar's field can only affect objects within a few thousand kilometers.
