NASA’s WFIRST Space Telescope Will Offer an Unprecedented Look at the Universe

You may have heard that it’s not smart to look directly at the Sun, and that’s for good reason—it’s pretty bad for you. But it turns out that stars can be problematic in a similar way when we’re looking out into space: their glare can stop us from seeing the stuff we want to see. […]

Space Elevator – Science Fiction or the Future of Mankind?

It’s hard to get to space As much as we all wish there were an easy, and affordable way to see our planet floating in the dark Right now, the only way is to become an astronaut or a billionare But there is a concept that might make it possible -while serving as the starting […]

Giant Leaps in Space Exploration with Nuclear Energy

– As we celebrate, 150th anniversary of Purdue, we have these four themes, and these four themes, actually, align perfectly with nuclear energy because it is about the future. The first theme is a space exploration. In order for a human to go on a long term mission in space, we can not use conventional […]

An Interstellar Mission Found Something Unexpected at Our Solar System’s Edge

Every 176 years, the four planets in our outer solar system present us with a rare opportunity. They’ll align in such a unique way, that it’s possible to use their gravitational forces to slingshot from one planet to the next. A PhD student figured this out back in 1965 during his summer job at the […]

Cosmic Queries – World Space Week with Neil deGrasse Tyson

– Hey YouTubers, up next, StarTalk Cosmic Queries, Space Week. (upbeat music) This is StarTalk. I’m your host, Neil deGrasse Tyson, your personal astrophysicist. And this is a Cosmic Queries edition where we are celebrating Space Week. That would be the first week of October. That happens to contain my birthday, I’m just sayin’. – […]

A Journey to the End of the Universe

What will happen to us in the next few hundred years? Or a thousand? How will the Universe end? How the heck should I know? Hey, nobody knows for sure, but we can gather all the existing theories together and find it out. Good thing we’ve got this time projector here to check it out […]

Interstellar Travel: Approaching Light Speed

Is interstellar travel doomed to remain in the realm of science fiction with faster than light travel and infinite improbability drives? Never mind warp speed, is light speed even possible? Technically no Light is massless and travels a little over 1 billion km/h Since spacecraft are not massless you need energy to accelerate as you […]

How Do Ion Engines Work? The Most Efficient Propulsion System Out There

People always ask me why we’re stuck with chemical rockets. Seriously, exploding a bunch of hydrogen or kerosene is the best we can do? Good news, there are other, exotic science fiction-sounding propulsion systems out there which use electromagnetic fields to accelerate atoms, allowing their spacecraft to accelerate for months at a time. I’m talking […]

Nuclear Space Propulsion

Nuclear thermal, we have been working nuclear thermal propulsion technology at a low level for years. This year the Space Technology Mission Directorate at NASA is picking it up in our Game Changing Development program and our focus right now on developing the fuel for a reactor, for a nuclear thermal propulsion system and so […]

Why Alien Life Would be our Doom – The Great Filter

Imagine NASA announced today that they found aliens. Bacteria on Mars, weird alien fish in the oceans of Europa, and also ancient alien ruins on Titan. Wouldn’t that be great? Well, no. It would be horrible news, devastating even. It could mean that the end of humanity is almost certain and that it might be […]
