✨A spacesuit weighs approximately 127 kg on the ground without the astronaut in it but in the microgravity environment of space, a spacesuit weighs nothing✨

✨Almost all of ordinary matter (99.9% of it) is empty space. If you took out all of the space in our atoms, the entire human race (all 7 billion of us) would fit into the volume of a sugar cube.

But the fact is that the density of that sugar cube will be extremely high and could weigh up to five billion tons✨

✨Active galaxy NGC 1275 lies at the heart of the Perseus Galaxy Cluster, it has huge filaments of gas that extend out from the core. They look like the tentacles of an immense galactic octopus and are 20,000 light years long, and just 200 light years wide. They are held in place by powerful magnetic fields from the massive central black hole✨

✨Famous globular cluster M13 has 100,000 stars packed into a space 150 light years across. The centre of this cluster is so crowded that it’s thought that stars crash into each other forming new suns called “blue stragglers”✨

Why Dark matter is called dark?

✨Dark matter is called dark because it does not appear to interact with the electromagnetic field, which means it doesn't absorb, reflect or emit electromagnetic radiation, and is therefore difficult to detect✨

How we know that dark matter exists?

✨Dark matter is known to exist through the gravitational effect it exerts on visible matter in the universe✨

✨The scientific term whereby one galaxy gravitationally disturbs another is called galaxy harassment✨

✨The Big Bang happened everywhere at once.

The universe has no center or edge, and every part of the cosmos is expanding. That means if we run the clock backward, we can figure out exactly when everything was packed together—13.8 billion years ago.Because every place we can map in the universe today occupied the same place 13.8 billion years ago, there wasn't a location for the Big Bang: Instead, it happened everywhere simultaneously✨

✨Our solar system travels through the Galaxy at 251 kilometres per second, as it orbits around the Milky Way’s centre. The Milkyu Way is so vast that even at this speed it takes 225 million years to do one orbit✨

Dark Energy

✨Dark energy is the name given to the mysterious force that’s causing the rate of expansion of our universe to accelerate over time, rather than to slow down. Dark energy does behave like Einstein’s anti-gravity force, but its nature and origin remain unknown. Recent observation of supernova have produced a value for an acceleration that implies a universe that is about 68% dark energy. One explanation for dark energy is that it is a property of space✨
