A coronal hole is an opening in the sun's atmosphere where magnetic field lines swing open instead of looping back, allowing continuous solar wind to escape at speeds up to 2 million mph. Unlike solar...
Moons in the universe come in many different types, including collision moons (like Earth's Moon formed from a planetary impact), captured moons (like Triton orbiting Neptune backwards), asteroid moons (small bodies orbiting asteroids), ring moonlets...
A solar eclipse occurs when the Moon passes between the Sun and Earth, blocking sunlight and creating a temporary darkness; this phenomenon can only be observed from within the Moon's shadow. A camera obscura is...
Saturn's rings are composed of billions of tiny icy pieces ranging from sand-sized grains to house-sized objects, with most parts being only about 100 meters thick, making them nearly invisible when viewed from the side;...
The Euclid Space Telescope has discovered that the visible matter in the universe—stars, gas, and galaxies—is insufficient to explain the gravitational forces holding cosmic structures together, revealing that an invisible 'dark matter' skeleton shapes galaxy...
This educational video introduces children to fundamental space vocabulary and celestial concepts, covering space exploration tools like rockets, space shuttles, and telescopes; the solar system including the sun and eight planets (Mercury, Venus, Earth, Mars,...
Alaska's summer 2026 has been cooler than normal, with temperatures 1.3 degrees below average across most of the state, and the rainy season has started earlier than usual around July 12-13. The official forecast predicts...
Betelgeuse, a red supergiant star 640-700 light-years away, has dimmed again in a way that defies existing astronomical models, revealing that our understanding of dying star behavior remains incomplete; the star exhibits two overlapping pulsation...
Our solar system consists of the sun at the center with eight planets orbiting around it: Mercury (closest to the sun, smallest, one day equals 59 Earth days), Venus (hottest planet, yellow clouds, one year...
Astronomers initially estimated the age of interstellar comet 3I/ATLAS at 7 billion years based on its orbital path through the galaxy, but this was later revised to 10-12 billion years using two independent chemical clocks:...
The universe is structured as a three-dimensional web of voids and clusters, with our Milky Way galaxy located in a large cosmic void called the KBC void. This void is shaped by two opposing forces:...
India achieved a historic milestone with Skyroot Aerospace's Vikram-1 rocket successfully reaching a 453-kilometer orbit on its first attempt, marking the nation's first private sector orbital launch and demonstrating that a 100% Indian-designed, manufactured, and...
The Vera C. Rubin Observatory, equipped with the world's largest digital camera for astronomy, accidentally discovered asteroid 2025 MN45 during equipment testing before its official mission began. This asteroid, measuring approximately 710 meters across, spins...
The Voyager spacecraft, launched in 1977, are powered by Radioisotope Thermoelectric Generators (RTGs) that convert heat from plutonium-238 decay into electricity. These nuclear batteries, requiring no moving parts, provided 470 watts at launch but have...
Human space exploration has evolved through distinct stages: first, people used their eyes to observe celestial bodies like the Sun, Moon, and five visible planets (Mercury, Venus, Mars, Jupiter, Saturn); then telescopes revealed planetary details...
