HH 30
Also known as V1213 Tauri, is a protoplanetary disk over 300 light-years from Earth.
Vostok 1
The first manned spaceflight in human history. It took place on April 12, 1961, with Yuri Gagarin flying over 327 km (203 mi) into space.
Black Hole
Black holes are both fascinating and scary!
Light-year
This distance light travels over the course of one year.
White Hole
A white hole is the theoretical opposite of a black hole. Some theories postulate that some, though not all, black holes might have a white hole as a counterpart.
Pulsar
Pulsars are rotating neutron stars that with a strong magnetic field (see magnetars) that emit electromagnetic radiation out of their poles. As they rotate, the radiation can be…
Dark Star
A hypothetical star that was driven by annihilation of matter and dark matter rather than the typical nuclear fusion normal matter like in all known stars. If they ever existed,…
Wormhole
Hypothetical structure in spacetime that connects two points separated by an arbitrary distance. A wormhole could be a bridge between two black holes, or perhaps one between a b…
Hypothetical Star
A hypothetical star is speculated or theoretical type of star that has never been observed, but could exist even as alternatives to black holes.
Neutron Star
Neutron stars are the collapsed remains of stars that have experienced a supernova. The stellar matter that isn’t scattered into space collapses back into itself due to gravity…
Magnetar
Magnetars are a type of neutron star, which are characterized by an extremely powerful magnetic field and a tendency to rotate slightly slower (~0.1-0.5Hz) than typical neutron…
Q Star
Q stars, also called gray holes, are hypothetical stars made of exotic matter. They would be massive enough to capture almost all light, but some would still be able to escape.
