Trivia

What makes it special

  • The Crab. The remains of a supernova that Chinese and Japanese astronomers recorded exploding in 1054 AD, bright enough to be visible in daylight for three weeks.

Hard to believe

  • Surface speed. Its equator is moving at roughly 1% of the speed of light. Spin it much faster and it would tear itself apart.

Handle with care

  • Its gravity. Surface gravity is around 190 billion times Earth's. A fall of one metre would end at roughly a tenth of the speed of light.

What it actually is

  • What it is. The collapsed core of a star that exploded: about one and a half Suns of matter crushed into a ball the size of a city, held up only by the refusal of neutrons to be squeezed further.
  • Reading the fog. Its dispersion measure is 56.8 — a count of the free electrons in every column of space between here and there. Those electrons slow the low-frequency pulses more than the high ones, and that lag is how its distance is worked out.

Find it in the sky

  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.
  • Best time of year. It stands highest in the middle of the night around December — that's when to go looking.

Standing on it

  • Why we can see it. We only know about it because its beam happens to sweep across the Earth. Most of the galaxy's pulsars are pointing somewhere else and are invisible to us.

About J0534+2200

J0534+2200 is an anomaly pulsar. It spins once every 33.392 ms, has a dispersion measure of 56.77 pc cm⁻³ and carries a surface magnetic field around 3.79×10^12 G.

The remains of a supernova that Chinese and Japanese astronomers recorded exploding in 1054 AD, bright enough to be visible in daylight for three weeks.

How to see it

Like any astronomical target, J0534+2200 is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.

Why J0534+2200 is an anomaly pulsar

J0534+2200 scores 97 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 23 points would lift it into a rarer tier.

That score comes from 2 science badges — Pulsar and The Crab Pulsar — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
