Mysterious object seen speeding past sun could be 'visitor from another star system'

If its origins are confirmed, the asteroid or comet, named A/2017 U1, will be the first object known to come from elsewhere in the galaxy, say astronomers A false-colour image of the object, which appears as a faint point of light in the centre. The streaks are stars, caused by the telescope tracking the object. A mysterious object detected hurtling past our sun could be the first space rock traced back to a different solar system, according to astronomers tracking the body. While other objects have previously been mooted as having interstellar origins, experts say the latest find, an object...

Why Would Anyone Invest in Interstellar Travel?

Alien, Avatar and Passengers are science fiction blockbusters with one thing in common. No, it’s not the earnings of the lead actors but the business model that underpins the plot. Each movie has a premise that involves long trips into space to transport something to or from Earth. In Alien the crew of the ship is towing a refinery back home. The refinery has been stocked with materials extracted from another planet. The concept of resource exploitation is revisited in Avatar, where the exomoon Pandora is mined for a mineral that has enormous value on Earth. Passengers has a related...

Does NASA Have Any Practical, Real-World Options For Achieving A Manned Interstellar Flight?

If movies are to be believed, NASA interstellar flight capability is just around the corner. Unfortunately, the reality of the situation is a bit different. Most people seem to vastly underestimate the incredible distances between the stars, and for NASA to traverse these distances will require either remarkably advanced propulsion technologies or new ways of thinking about exploration. The Challenge for NASA Interstellar distances are so vast as the virtually beggar the imagination. The distance to the nearest star – Alpha Centauri – is over 25 trillion miles. That’s trillion with a T. And that’s just the nearest one. At...

NASA's Voyager I Enters Interstellar Space

NASA's Voyager I spacecraft has been steadily journeying away from the sun to the outer reaches of the solar system since its 1977 launch. As it travels farther out and enters a different region of the solar system, it's occasionally affected by coronal mass ejections -- shock waves caused from massive violent eruptions from our sun. There have been three of these space "tsunamis" since 2012, and the third one -- described by NASA on Monday -- has helped the space agency confirm something it posited in late 2013: that Voyager is the first Earth craft to travel into interstellar...
