  3. Imagine the Universe!

    Travel Time. The Voyager spacecraft is traveling away from the Sun at a rate of 17.3 km/s. If Voyager were to travel to the center of our Galaxy, it would take more than 450,000,000 years to travel the 8 kpc. If it could travel at the speed of light, an impossibility due to Special Relativity, it would still take over 26,000 years to arrive!

  5. How fast are we traveling through space?

    How fast are we traveling through space? A person on the equator rotates around the Earth at approximately 1,660 kilometers per hour. In contrast, a person at the North or South Pole has a rotational speed of zero and effectively turns on the spot. A person's rotational speed decreases as they move from the equator toward the pole; for instance ...

  6. The Milky Way Galaxy

    Using infrared images from NASA's Spitzer Space Telescope, scientists have discovered that the Milky Way's elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Previously, our galaxy was thought to possess four major arms. The annotated artist's concept illustrates the new view of the Milky Way.

  10. Milky Way

    The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.. The Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years), [10] but ...

  12. Our Motion Through Space Isn't A Vortex, But Something Far ...

    There are literally trillions of large masses in our Solar System, all orbiting around the galactic center on timescales of hundreds of millions of years. But there's a viral video, parts 1 and 2 ...

  13. How, exactly, does planet Earth move through the Universe?

    Although the Sun orbits within the plane of the Milky Way some 25,000-27,000 light years from the center, the orbital directions of the planets in our Solar System do not align with the galaxy at all.

  14. Our Fascinating Universe

    We inhabit a galaxy known as the Milky Way, which contains hundreds of billions of stars. How did we arrive at this point, and what is our future? These conc...

  15. galaxy

    Galaxies move through space with velocities of the order of a several 100 km per second; small velocities for small groups (~100 km/s; e.g Carlberg et al. 2000) and large velocities for rich clusters (~1000 km/s; e.g Girardi et al. 1993).. In addition to this so-called "peculiar velocity", galaxies also also carried away from each other due to the expansion of the Universe, at a velocity ...

  16. Intergalactic travel

    Intergalactic travel is the hypothetical crewed or uncrewed travel between galaxies.Due to the enormous distances between the Milky Way and even its closest neighbors—tens of thousands to millions of light-years—any such venture would be far more technologically and financially demanding than even interstellar travel.Intergalactic distances are roughly a hundred-thousandfold (five orders ...

  17. Milky Way Galaxy Facts

    The Milky Way moves through space at a velocity of about 552 kilometres per second (343 miles per second) with respect to the Cosmic Microwave Background radiation. The Milky Way's central core contains a supermassive black hole. It is commonly referred to as Sagittarius A*. It contains the mass of about 4.3 million Suns.

  18. Our Milky Way Galaxy: How Big is Space?

    Light zips along through interstellar space at 186,000 miles (300,000 kilometers) per second (more than 66 trips across the entire United States, in one second). Multiply that by all the seconds in one year, and you get 5.8 trillion miles (9.5 trillion kilometers). Just for reference, Earth is about eight light minutes from the Sun.
