โšก Quasars & Pulsars

The cosmic lighthouses and powerhouses of the universe โ€” brighter than galaxies, older than stars, stranger than imagination.

Quasars and pulsars are extreme objects powered by the most violent forces in the cosmos โ€” gravity, collapse, and supermassive black holes.

Their signals travel across billions of light-years, acting as cosmic time capsules from the early universe.

Quasar vs Pulsar: Whatโ€™s the Difference?

Quasar ๐Ÿ”ฅ Pulsar ๐ŸŽฏ
Type Supermassive black hole-powered object Highly magnetized rotating neutron star
Brightness Brighter than the Milky Way galaxy Seen as rhythmic radio/light pulses
Location Center of extremely distant galaxies Often in our Milky Way
Signals Energy jets & radiation Precise repeating pulses (like clocks)

Quasars

A quasar is powered by a supermassive black hole consuming matter at incredible speeds. As gas spirals inward, it heats up, releasing enormous amounts of energy โ€” sometimes forming jets that span millions of light-years.

The brightest known quasar emits energy equal to *600 trillion Suns*.

Pulsars

Pulsars are neutron stars โ€” the collapsed cores of massive supernova explosions. They emit beams of radiation from their magnetic poles, and as they spin, these beams sweep across Earth like a lighthouse.

Some spin faster than a blender motor โ€” more than 700 times per second.

Famous Examples

โœจ 3C 273 โ€” The First Quasar

Discovered in 1963 โ€” still one of the brightest and closest quasars.

๐ŸŽฏ The Crab Pulsar

Created from a supernova explosion seen on Earth in 1054.

๐ŸŒ€ PSR J1748โ€“2446ad

The fastest known pulsar โ€” spinning over 716 times per second.
