Jeff Bezos just made history this morning, he along with his Blue Origin Crew successfully completed its first-ever passenger launch to space in Van Horn, Texas. Inside the high-flying New Shepard 16 vehicle was his brother Mark Bezos, 82-year old aviator Wally Funk and 18-year-old Oliver Daemen.

HARVARD PROFESSOR SAYS ALIEN OBJECT VISITED US IN 2017—AND MORE ARE COMING
In his upcoming book published by Houghton Mifflin Harcourt, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth, Harvard astronomer Avi Loeb makes a provocative assertion: The mysterious “cigar-shaped object” that NASA dubbed “1I/2017 U1 ‘Oumuamua” was junk from an alien civilization.
Why a Mission to a Visiting Interstellar Object Could Be Our Best Bet for Finding Aliens
Life may exist elsewhere in the Milky Way galaxy, though try as they might, scientists have yet to detect any sign of it. Part of the problem has to do with the size of space; finding traces of organic substances or the waste signatures of alien megastructures isn’t easy at such cosmic distances. Fortunately, there’s the possibility that alien life will come to us in the form of interstellar objects.

We could move to another planet with a spaceship like this
Proxima b, our nearest neighboring exoplanet, is almost 25 trillion miles away. Even one of our fastest spaceships—the 31,600-mile-per-hour New Horizons—would take hundreds of thousands of years to get there. Assuming we can’t figure out how to warp space-time (seems unlikely, but fingers crossed), we’re still looking at a couple-hundred-year trip in the best-case scenario, which leads to the real problem: No human crew could survive the entire ride. Science-fiction writers have long floated so-called generation ships as a solution. Designers would outfit these interplanetary cruise vessels to support a community of adults and their children, and their children’s children, and their children’s children’s children…until humanity finally reaches a new celestial shore. Here’s our best guess for what it would take to sow the seeds of an extrasolar species.

Wild New Theory Suggests Radio Bursts Beyond Our Galaxy Are Powering Alien Starships
Since their discovery ten years ago, fast radio bursts have confounded astronomers. These intergalactic pulses of radio energy have defied explanation, but a new theory suggests a technological origin, whereby aliens use these beams to propel their ships through space. Extremely speculative stuff, to be sure, but it’s an idea worth pursuing given just how weird these pulses are.

What Is the Limit to How Far We Can Travel in Space?
Bad news, guys. There’s a limit to humanity. Even if we had the technology for interstellar space travel, we still wouldn’t be able to see most of the observable universe because we’re actually limited to only being able to go to a hundredth billionth of a percent of it. We’re stuck within our local galaxy group. That’s sort of depressing! But why is there a limit anyway? Kurzgesagt explains how it has to do with dark energy, and the nature of nothing, and how only so many things in the universe are gravitationally bound to us.

How Traveling to Deep Space In Cryogenic Sleep Could Actually Work
Our bodies aren’t meant for space. We require too much maintenance to speed through the stars. We need a steady supply of things absent from space — namely water, food and oxygen. We crave warmth but won’t find it in deep space, where the average temperature is -455 degrees Fahrenheit. Even if we could survive in an icy vacuum without sustenance, we’d probably go insane without distractions and room to move.
