Cosmic Facts
Explore mind-blowing facts about our universe in a quick scroll.
Jupiter's Great Red Spot is a massive cosmic storm that’s been raging for over 400 years — large enough to engulf Earth twice
A neutron star is so dense that just one teaspoon of its matter would weigh about 10 million tons — a mind-bending space phenomenon
The Hubble Space Telescope orbits Earth at 17,000 mph — capturing deep space galaxies every 95 minutes in breathtaking clarity
There are more stars in the known universe than grains of sand on all Earth’s beaches — a reminder of the vastness of space
The Sun makes up 99.86% of the total mass in our solar system — truly the gravitational heart of planetary motion
A day on Venus lasts longer than its year — 243 Earth days to rotate once versus 225 to orbit the Sun, due to slow planetary spin
Light from the Andromeda Galaxy takes 2.5 million years to reach us — offering a glimpse into the ancient universe and cosmic past
Saturn’s rings are made mostly of water ice and span over 170,000 miles wide — one of the most iconic wonders in space science
Black holes can warp time and space — with gravitational forces so extreme not even light can escape their event horizon
Earth’s magnetic field protects us from solar radiation — acting as a natural shield against harmful cosmic and solar particles

Quasi-Stellar Objects: The True Stellar Illusion
Quasi-Stellar Objects (QSOs) look like stars through small telescopes, but they’re not stars. They’re actually incredibly bright, energetic sources, powered by supermassive black holes at the centers of young galaxies.
The Cognitive Limits of Human Astronomy
Cognitive constraints are the extent to which the human mind can be stretched while trying to understand the things which are meaningless in our daily life
The Cosmic Brain Mystery: Are We Living Inside One?
The cosmic web is this massive structure where galaxies, clusters, dark matter, and gas stretch across the universe like a tangled spider’s web.
