Amazon CEO Jeff Bezos told reporters at the U.S. Space Symposium in Colorado Springs that he plans to sell $1 billion in Amazon stock every year and funnel the proceeds into his spaceflight company Blue Origin, CNBC reports. Blue Origin aims to start test flights with company pilots and engineers either this year or next, with a goal towards offering 11-minute commercial flights that enable passengers to experience weightlessness and see the curvature of the earth.

Why it matters: America's brightest entrepreneurial minds like Bezos and Elon Musk are investing enormous time and money into space flight. Musk's company SpaceX says it will fly private citizens around the moon next year, and both believe we can send a human to Mars within a decade and should ultimately aim to build a human colony there.

We've all heard about black holes, but no one has actually captured an image of one, including the event horizon — the edge of a black hole from which light can't escape. For the first time, scientists have put together a worldwide project called the Event Horizon Telescope in an attempt to finally get a look at a black hole, per Vox.

• The target: Sagittarius A, the presumed supermassive black hole that sits at the center of our galaxy, located about 26,000 light years away. For a sense of scale, trying to capture an image of Sagittarius A is like trying to snap a picture of a DVD on the moon, a University of Arizona astrophysicist told Vox.
• The plan: Point 8 giant radio telescopes located around the world at Sagittarius A for 10 straight days — in effect, creating a virtual Earth-sized telescope — in an attempt to generate enough data to get a look.
• The benefits: It could provide our best confirmation yet of Einstein's theory of relativity, and scientists might finally be able to test Stephen Hawking's theory that black holes lose mass over time.
