Trivia

Hard to believe

Record spin. It completes a full rotation in 2 milliseconds — faster than a kitchen blender, on an object heavier than the Sun.
Surface speed. Its equator is moving at roughly 11% of the speed of light. Spin it much faster and it would tear itself apart.
Better than a clock. Millisecond pulsars keep time so well that a network of them is being used as a galaxy-sized detector for gravitational waves — more stable over decades than the best atomic clocks.

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 82.1 — 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.
It has a partner. It orbits a companion star, and because its pulses are such a precise clock the orbit can be traced to extraordinary accuracy. A binary pulsar is how gravitational waves were first proven to be real, decades before one was directly detected.

Find it in the sky

Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.

About J1737-0314A

J1737-0314A is an epic pulsar. It spins once every 1.98 ms, has a dispersion measure of 82.1 pc cm⁻³ and carries a surface magnetic field around 440,170,739 G.

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.

How to see it

Like any astronomical target, J1737-0314A 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 J1737-0314A is an epic pulsar

J1737-0314A scores 54 points on Spacedle's rarity scale, which places it in the epic tier. Another 24 points would lift it into a rarer tier.

That score comes from 3 science badges — Pulsar, Millisecond pulsar and Binary 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.
