Explore why the Crab Nebula matters to astronomy, from a historic supernova to a powerhouse of pulsar and multiwavelength research.

Learn what the Geminid meteor shower is, when it peaks, why it shines so brightly, and how to see it at its best.

Learn what a shooting star is, why it appears, and how to identify meteor streaks in the night sky.

Some supernovae leave behind black holes because the collapsing core becomes too massive for neutron degeneracy pressure to support.

Learn how neutron stars work, from collapse and neutron degeneracy pressure to pulsars, magnetars, and the extreme physics inside these compact remnants.

Discover why nebulae glow in vivid reds, greens, and blues, and how gases, dust, and starlight create their striking colors.

Explore how rotating neutron stars become pulsars, why their beams sweep the sky, and what makes these stellar remnants such precise cosmic clocks.

Learn what a planetary nebula is, how it forms, and why these glowing gas shells reveal the final stage of Sun-like stars.

Discover why nebulae are called stellar nurseries, how stars form inside them, and which physical processes turn cosmic gas into new suns.
