What is so special about the Pleiades? Most stars are single and separate from each other, but the Pleiades packs more than a handful into a compact bunch that stands apart from nearly everything else in the sky. The Pleiades is...
How many parsecs away is Pleiades? As detailed in a pair of articles here and here, ground-based methods had consistently shown that the Pleiades lie about 435 light-years (133 parsecs) away. How did we find the distance to Pleiades? NRAO asronomers...
How far apart are the 7 sisters? Now, astronomers have more precisely estimated the distance to be 444 light-years. Are Pleiades stars physically associated with each other? The Pleiades (Kartika) are particularly revered in Hindu mythology as the seven mothers of...
How long would it take to exit our solar system at light speed? In an hour, light can travel 671 million miles. Earth is about eight light minutes from the Sun. A trip at light-speed to the very edge of our...
How long would it take to travel to a different universe? It would take an infinite amount of time to traverse the universe. That’s because the universe will continue to expand whilst you are travelling, and so there are regions of...
How long does it take light to reach the edge of the universe? So if we simply wanted to know how long it would take light to reach the edge of the visible universe, the answer would be 47 billion years...
Will Earth ever leave the Milky Way? “It’s very unlikely,” Matteo Ceriotti, an aerospace engineer and space systems engineering lecturer at the University of Glasgow in the U.K., told Live Science in an email. However, as Ceriotti explained, “unlikely” does not...
How long would it take to get to the edge of our solar system at the speed of light? A trip at light-speed to the very edge of our solar system – the farthest reaches of the Oort Cloud, a collection...
How long would it take to exit our galaxy? The nearest galaxy: 749,000,000 (that’s 749 million) years. The end of the known universe: 225,000,000,000,000 years (that’s 225 trillion) years. Can we reach the end of our galaxy? So, to leave our...
Could we ever travel to another galaxy? The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that...
