Orion Separation

The human-rated crew capsule is on the way to the moon after a seemingly picture-perfect launch on the maiden flight of NASA’s Space Launch System moon rocket.

Want a closer look? These two galaxies are thought to have existed 350 & 450 million years after the big bang (left to right). Unlike our Milky Way, these first galaxies are small and compact, with spherical or disk shapes rather than grand spirals.

‍This discovery suggests that stars might have started forming earlier than expected, perhaps as soon as 100 million years after the big bang. Follow-up observations with Webb’s spectrographs will confirm the distances of these 2 galaxies & help us learn more.

Why Don't We Shoot Nuclear Waste Into Space?

Here in the Kurzgesagt labs we test very important ideas to see what happens when you blow things up or play with black holes. Many of you suggested that we look into an idea that sounds reasonable: Shooting nuclear waste into space. It is one of those concepts that seems like an easy fix for one of the main problems with nuclear energy. But it turns out this idea is not just bad but horribly bad and it gets worse the longer you think about it.

TIMELAPSE OF THE ENTIRE UNIVERSE - 13.8 Billion Years in 10 Minutes (1080p)

Watch on YouTube

It can be difficult to fathom how long 13.8 billion years is. The more you watch this video, the more it sinks in just how stunningly old the universe is, and how magnificently tiny we humans are in the grand scheme. I hope seeing this experiment in humility makes you ponder the vast, unwitnessed ages that have passed before we came along, and the brevity of our existence in comparison.

TIMELAPSE OF THE FUTURE: A Journey to the End of Time (1080p)

Watch on YouTube (4K)

How's it all gonna end? This experience takes us on a journey to the end of time, trillions of years into the future, to discover what the fate of our planet and our universe may ultimately be.

We start in 2019 and travel exponentially through time, witnessing the future of Earth, the death of the sun, the end of all stars, proton decay, zombie galaxies, possible future civilizations, exploding black holes, the effects of dark energy, alternate universes, the final fate of the cosmos - to name a few.

This is a picture of the future as painted by modern science- a picture that will surely evolve over time as we dig for more clues to how our story will unfold. Much of the science is very recent and new puzzle pieces are still waiting to be found.

We WILL Fix Climate Change!

Our home is burning. Rapid climate change is destabilizing our world. It seems our emissions will not fall quickly enough to avoid runaway warming and we may soon hit tipping points that will lead to the collapse of ecosystems and our civilization.

While scientists, activists and much of the younger generation urge action, it appears most politicians are not committed to do anything meaningful while the fossil fuel industry still works actively against change. It seems humanity can’t overcome its greed and obsession with short term profit and personal gain to save itself.

And so for many the future looks grim and hopeless. Young people feel particularly anxious and depressed. Instead of looking ahead to a lifetime of opportunity they wonder if they will even have a future or if they should bring kids into this world. It’s an age of doom and hopelessness and giving up seems the only sensible thing to do.

But that’s not true. You are not doomed. Humanity is not doomed.
