From the beginning of time, humans have been fascinated by the stars and the heavenly bodies. Even the term 'beginning of the time' is shrouded in mystery — how did the universe come into existence? Was there really a Big Bang? Are we the only smart ones in this vast universe?
The questions about space are endless, and well, it's too soon for them to stop.
The universe's backstory is vast and, not to forget, ever changing. As we delve into another era of space exploration, with the recent success of the SpaceX, it only seems natural that we sit back and enjoy the beauty of this frontier we call space.
So, here we are with yet another series of stunning space wallpapers in both HD and 4K. Some of these images may not be actual pictures, but are the result of an artist's creative imagination. As always happy exploring!

Did you know that a shooting star or a falling star, as it's known in some places, is not really a star? These are actually meteoroids – small pieces of space rocks – that burn up as they enter the Earth's atmosphere.
Nebulae or Nebula are the remnants of dead stars. The gasses and dust from dead stars mix together to form a Nebula - a cloud of dust. Did you know that Nebulae are never stationary and are always in motion?
Home to Sun, the Milky Way is a spiral-shaped galaxy. This galaxy has a whopping 200 billion stars! Interestingly, our Solar system is just a tiny speck on it and is 27,000 lightyears away from the center of the galaxy.
As opposed to the popular belief, one can't see a million stars at one glance. On a perfectly clear night, we can only see around 2,500 to 3,000 stars. This can mainly be attributed to the fact that the stars are not bright enough to be visible to the naked human eye.
Did you know that NASA's Hubble Space Telescope has discovered an intriguing dust structure enveloping a young star? This dust structure is said to be around 150 billion miles across and might be the result of the gravitational pull of an unseen planet.
If you ask me, this planet must be supermassive to yield such a massie gravitational pull.
As recently as March 2018, NASA's Hubble Space Telescope is reported to have found a relic galaxy near the Milky Way. Going by the name of NGC 1277, this galaxy is referred to as a relic since it used to churn out stars at an accelerated rate previously. However, it has now slowed down drastically.
It's estimated that the smallest galaxy in the universe may contain only a few hundred stars. Often dwarf galaxies are found clustered around bigger galaxies. The fewer number of stars areoften attributed to (again) the bigger gravitational pull of the bigger stars.
Did you know that hydrogen and helium are two of the major gases in space? Theoretically, it is often believed that a river of hydrogen may exist in the intergalactic space, though it's still not been proven.
Why leave out the place which gave birth to humanity? This is a view of Mother Earth taken from the International Space Station (ISS). Located approximately 254 miles above the surface of the Earth, the ISS orbits our blue planet at a whooping 17,000mph.
