What is the Lyman-alpha forest?
The Lyman-alpha forest is a series of absorption lines in the spectra of distant quasars caused by intervening hydrogen clouds in the intergalactic medium. It helps astronomers study the distribution of matter in the universe.

See lessWhat is a solar system's habitable zone?
The habitable zone, or Goldilocks Zone, is the region around a star where conditions might be right for liquid water to exist on the surface of a planet, making it potentially suitable for life.

See lessWhat is a Cepheid variable star?
A Cepheid variable star is a type of star that fluctuates in brightness with a regular period. These stars are important for measuring astronomical distances because there is a well-defined relationship between their pulsation period and luminosity.

See lessWhat is a neutron star merger?
A neutron star merger occurs when two neutron stars in a binary system spiral towards each other and collide. This event can produce gravitational waves, heavy elements, and gamma-ray bursts

See lessWhat is a gravitational lens?
A gravitational lens is a phenomenon where the gravity of a massive object, like a galaxy or black hole, bends and magnifies the light from objects behind it, allowing us to observe distant and faint galaxies.

See lessWhat is a rogue planet?
A rogue planet is a planetary-mass object that does not orbit a star and instead drifts through interstellar space. It may have formed around a star and been ejected or formed in isolation.

See lessWhat is the difference between a galaxy and a star cluster?
A galaxy is a vast system of stars, gas, dust, and dark matter bound together by gravity. A star cluster is a group of stars that are gravitationally bound to each other and are often found within a galaxy.

See lessWhat is the heliosphere?
The heliosphere is a vast bubble of solar wind and magnetic fields surrounding the solar system. It marks the boundary where the solar wind meets the interstellar medium.

See lessWhat is a blue supergiant?
A blue supergiant is a massive star in the later stages of its evolution. It is much hotter and more luminous than a red giant and is blue due to its high surface temperature.

See lessWhat is a gamma-ray burst?
A gamma-ray burst (GRB) is an extremely energetic explosion observed in distant galaxies, characterized by a brief but intense burst of gamma-ray radiation. GRBs are thought to result from events like the collapse of massive stars into black holes or the merging of neutron stars.
