Does sound travel in space?
✨No, we cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel✨

What's inside a blackhole?
✨While they may seem like a hole in the sky because they don't produce light, a black hole is not empty, It's actually a lot of matter condensed into a single point. This point is known as a singularity✨

Will the Universe Ever End?
✨The universe had a definite beginning, called the Big Bang. It's ending is more like the "long, slow expansion". The truth is, the universe is slowly dying as it expands and grows and gradually cools. It will take billions and billions of years to cool completely and stop its expansion✨

How Many Stars Can We See at Night?
✨That depends on many factors, including how dark the skies are where. In light-polluted areas, people see only the brightest stars and not the dimmer ones. Out in the countryside, the view is better. Theoretically, with the naked eye and good seeing conditions, an observer can see around 3,000 stars without using a telescope or binocular✨

✨The dust sculptures of the Eagle Nebula are evaporating. As powerful starlight whittles away these cool cosmic mountains, the statuesque pillars that remain might be imagined as mythical beasts. Featured here is one of several striking dust pillars of the Eagle Nebula that might be described as a gigantic alien fairy. This fairy, however, is ten light years tall and spews radiation much hotter than common fire. The greater Eagle Nebula, M16, is actually a giant evaporating shell of gas and dust inside of which is a growing cavity filled with a spectacular stellar nursery currently forming an open cluster of stars. This great pillar, which is about 7,000 light years away, will likely evaporate away in about 100,000 years✨

Where does space begin? How high is the atmosphere?
Have you ever wondered, where does space begin? Exactly how high is the atmosphere? How far up do you have to go before you're in space? What separates the Earth from space? We get asked these questions all the time, and the answer relies on understanding…
How Long Does a Star Live?
✨Compared to humans, stars live incredibly long lives. The shortest-lived ones can shine for tens of millions of years while the old-timers can last for many billions of years. The study of star's lives and how they are born, live, and die ls called "stellar evolution", and involves looking at many types of stars to understand their life cycles✨
