Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.

Pluto is Hades

I find it funny that, in roman mythology, the dwarf planet Pluto is named after Hades, god of the underworld. In mythology, Hades is hated and forces to rule the dreadful underworld as an outcast and Pluto is in the far back of the solar system. Away from the other terrestrial planets. How appropriate naming

Largest Known Object in the Universe

The largest structure in the universe is called the Hercules-Corona Borealis Great Wall or Great Gamma Ray Burst Wall. A gamma ray burst is the brightest electromagnetic event in the universe and is believed to be the result of dying stars within distant galaxies ultra-energetic explosion of gamma-ray radiation. The wall seems to be getting bigger and its existence boggles the minds of even scientists! Another object of similar magnitude is a supercluster which isn't even an object but rather a region of an absence of matter!

Nile River As Seen From Space

The Nile River at night taken by astronaut Scott Kelly aboard the International Space Station. The knots of bright light show areas of high population density. This was posted to Twitter as part of Kelly's Year in Space photo project.

Earth 2.0

This is an artist impression of a newly discovered planet 1400 light-years from us called Kepler 452b and its discovery by NASA's Kepler Space Telescope marks the first time scientists have found a rocky planet that appears to orbit a Sun-like star at nearly the exact same distance that our planet Earth orbits the Sun.

Astrophysicist Neil Degrasse Tyson gives us a brief history of the formation of the universe and how everything (including us) came to be. It's mind-boggling to believe how if it weren't for the birth of an undistinguished star born in an undistinguished region of an undistinguished galaxy in an undistinguished part of the universe we would probably not exist! Most of all did you know every one of our bodies' atoms is traceable to the Big Bang and the thermonuclear furnace within high-mass stars?! Also I agree with the notion we are born from the universe and we've been empowered by it to figure itself out!

Actual Building Blocks of Planets Spotted for First Time Ever

Never before have we seen the in-between stages of planet formation, that is when extremely fine dust forms larger pebbles that eventually coalesce into planets over billions of years. A star called DG Tauri that is 450 light years and just 2.5 million years old appears to have an extensive ring of these pebbles around it and offers a glimpse into the beginnings of planetary formation. The data was acquired using the e-MERLIN array, a collection of 7 telescopes across England that uses interferometry which mimics the observation power of a much larger telescope.

This is Neil deGrasse Tyson talking about how we are all made up of stars. What made you, made me, and everyone else. It is amazing how everything in the universe is all connected. Feel big when you look at the universe, not small.

Proof That You Can't Cry In Space

Contributed by Dom Harris

Since most of us have never been without gravity, it is hard to imagine how different things would be. This short video shows us how a water soaked washcloth looks when it is wrung out in space. The water simply stays on the cloth since gravity isn't pulling it to the ground.
