About J1907+0919
J1907+0919 is an anomaly pulsar. It spins once every 5,198.346 ms and carries a surface magnetic field around 7.00×10^14 G.
The most magnetic object known in the universe — it could wipe a credit card from halfway to the Moon.

Trivia
What makes it special
- Magnetar. The most magnetic object known in the universe — it could wipe a credit card from halfway to the Moon.
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.
- Do not approach. Inside a thousand kilometres its field would pull the atoms in your body into thin needles and shut down every chemical reaction keeping you alive. It is lethal long before its gravity is.
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.
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.
- Best time of year. It stands highest in the middle of the night around July — 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.
By the numbers
- Density. A sugar-cube of its core would weigh about a billion tonnes — as much as every car on Earth put together.

How to see it
Like any astronomical target, J1907+0919 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 J1907+0919 is an anomaly pulsar
J1907+0919 scores 82 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 38 points would lift it into a rarer tier.
That score comes from 2 science badges — Pulsar and Magnetar — 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.
