Outer space may be cold and bleak and unspeakably huge, but at least it’s full of far-out objects with bonkers-sounding names like “blitzar,” “black dwarf,” and “dark energy star.” Set course for lava planet ASAP.
It’s a galaxy without reserves of star-forming matter.
Five galaxies sharing a compact space.
A literal hellworld.
A star no bigger than a large city, made of neutron matter that emits strong radio waves at regular intervals.
A pulsar that horned its way into the core of another star.
An energetic supermassive black hole at the center of a galaxy actively gobbling matter.
Fast Radio Burst
A neutron star with an extra-powerful magnetic field.
An unusual galaxy where most of the stars are contained in a ring far from the center of the galaxy.
After the Sun goes red giant, it will become a white dwarf. After the white dwarf expends its electron matter, it will go dark and become a black dwarf. This is trillions of years in the future and we will all be dead by then.
An old-timey term for an object too massive to be a planet and too small to be a star. We call them brown dwarfs now. Which is too bad.
When a star large enough to go supernova explodes, its core typically collapses into either a neutron star or a black hole. A blitzar is a neutron star that spins so fast it collapses into a black hole.
Relativistic Time Dilation
tauri might only feel like a few months to astronauts inside the ship, while Earth experiences it as a 4.3-year voyage.
A hot, luminous star that has lost nearly all of its hydrogen and is now burning and fusing helium.
Dark Energy Star
A really cool sounding object that probably doesn’t exist. A small group of physicists think black holes might not exist and the candidates we’ve discovered so far are actually weird, dense dark energy-producing stars.
Since they probably don’t exist, here’s a picture of a dog swimming instead. I’m sorry to have lied to you.
Primordial Black Hole
Theoretical intermediate-mass black holes that formed in the weird hot matter soup in the moments just after the Big Bang and now roam the universe silently, unseen.
A really, really, really bright, powerful supernova.
A seemingly rocky planet that’s actually a gas giant that had its atmosphere stripped away.
