But after his [appearance](http://time.com/3964238/yuri-milner-breakthrough-listen/) with Russian billionaire Yuri Milner on Monday to announce [Breakthrough Listen](http://www.breakthroughinitiatives.org/), the new $100 million initiative looking for signs of intelligent life, the famous physicist seems to have at least partially reconsidered. Hawking famously revealed his worry that any aliens advanced enough to contact earth would be “looking to conquer and colonize whatever planets they could reach” during a 2010 episode of the miniseries _Into the Universe with Stephen Hawking._ And he clearly hasn’t changed his mind completely. “If you look at history, contact between humans and less intelligent organisms have often been disastrous from their point of view, and encounters between civilizations with advanced versus primitive technologies have gone badly for the less advanced,” he told reporters at the Breakthrough announcement. “A civilization reading one of our messages could be billions of years ahead of us. If so, they will be vastly more powerful, and may not see us as any more valuable than we see bacteria.” Still, he said, the initiative is of special importance in a moment when humanity’s [achievements](http://time.com/3958195/pluto-new-horizons-survives/) in [space](http://time.com/3948364/moon-landing-apollo-11-margaret-hamilton/) are in the [spotlight](http://time.com/3920486/philae-comet-lander-hibernation-awake/). “We are alive. We are intelligent. We must know,” he said of the search for life beyond earth. Breakthrough Listen will provide funding explicitly for the search for extraterrestrial life, scanning the million stars closes to Earth and portions of 100 neighboring galaxies but _not_ for sending messages or signals to communicate with that life, an important distinction for scientists like Hawking, who are concerned with the possible consequences of contact. Instead, a second program, Breakthrough Message, will host a competition in which anyone can submit ideas for potential interplanetary messages. ## Transcript [ MUSIC ] What does it mean for a galaxy to be the most distant confirmed galaxy in the universe? The numbers are staggering. Here's what you need to know. [ NOISE ] [ MUSIC ] It's official name is Zagnd5296, but it's better known as the most distant galaxy ever discovered. A light year is the distance light travels in on e year, which comes out to 9. 4605284 times ten to the 15 meters. In simpler terms, it's about 9. 5 trillion kilometers, or about 6 trillion miles. Multiply that by 30 billion. And that's how far away ZAGND5296 is, and what exactly is the galaxy? It's a collection of stars that's part of the structure of the universe. The incredible distance between us and that farthest away galaxy means that we are just now seeing what it was like 13 billion years ago. Because that's how long it took for the light from the galaxy to reach telescope's sensors. It's so far away, that it required two of the world's most powerful telescopes for astronomers to make observations. The Hubble Space Telescope, and the Keck Telescope. We can treat this galaxy like a fossil, something that gives us a glimpse of the evolution of galaxies. It's a hint of what the universe was like at the young age of 700 million years old, a mere five percent of it's current age which is estimated to be 13. 8 billion years. Some notable things about this particular galaxy include a tiray of producing stars, and a shroud of hydrogen gas surrounding it, which scientists haven't found in the modern universe. We'll learn more about this galaxy with the introduction of the next generation James Webb space telescope in 2018, which will have more than 17 times the light gathering power of the Hubble. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3967126/stephen-hawking-seti-extraterrestrial-life-breakthrough/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3967126/stephen-hawking-seti-extraterrestrial-life-breakthrough/"},"headline":"Stephen Hawking Endorses New Hunt for Alien Life, Despite Fear of Being 'Conquered and Colonized'","datePublished":"2015-07-22T07:20:53.000Z","dateModified":"2026-08-04T08:05:52.210Z","description":"\"We are alive.
