What is space debris?
Space debris, also known as space junk, refers to defunct human-made objects in orbit around Earth, including spent rocket stages, derelict satellites, and debris from collisions and explosions. Space debris poses a risk to active satellites and spacecraft and has become a growing concern for spaceRead more

Space debris poses a risk to active satellites and spacecraft and has become a growing concern for space agencies and operators.
See lessWhat is a coronal mass ejection (CME)?
A coronal mass ejection (CME) is a massive expulsion of plasma and magnetic field from the Sun's corona into space, often associated with solar flares and solar prominences. CMEs can cause geomagnetic storms and disrupt satellite communications and power grids on Earth.

See lessWhat is the Drake Equation?
The Drake Equation is a probabilistic formula used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy, taking into account factors such as the rate of star formation, the fraction of stars with planets, and the likelihood of life developing on thosRead more

See lessWhat is cosmic inflation?
Cosmic inflation is a theoretical rapid expansion of the early universe believed to have occurred within the first fraction of a second after the Big Bang, explaining the large-scale homogeneity and isotropy of the universe.

See lessWhat is a gamma-ray burst?
A gamma-ray burst (GRB) is an intense and short-lived burst of gamma-ray radiation observed in distant galaxies, thought to be associated with supernova explosions or the merging of neutron stars.

See lessWhat is a black dwarf?
A black dwarf is a hypothetical stellar remnant that results from the cooling and fading of a white dwarf over billions of years. No black dwarfs are believed to exist yet, as the universe has not existed long enough for white dwarfs to cool to this state.

See lessWhat is a neutron star?
A neutron star is an extremely dense and compact stellar remnant formed when a massive star undergoes a supernova explosion and collapses under its own gravity, packing the mass of several suns into a sphere roughly the size of a city.

See lessWhat is a white dwarf?
A white dwarf is a dense stellar remnant formed when a low to medium-mass star exhausts its nuclear fuel and sheds its outer layers, leaving behind a hot, compact core composed mainly of electron-degenerate matter.
