Andromeda’s Great Spiral Galaxy (M31) is located just 2.5 million light-years away and is the closest large spiral to our own Milky Way. It can be viewed with the unaided eye as a small, faint, fuzzy patch, but because its surface brightness is so low, casual stargazers will not be able to appreciate the galaxy’s impressive extent in planet Earth’s sky. Read more for a video showing what may happen when our galaxies collide.

This collision is predicted to occur in about 4.5 billion years and since the stars involved are far enough apart, it’s improbable that any of them will individually collide. However, some stars will be ejected from the resulting galaxy, nicknamed Milkomeda or Milkdromeda. These types of collisions are actually somewhat common on a universal scale, as Andromeda, is believed to have collided with at least one other galaxy in the past.

  • Computerized star locating telescope: The Celestron NexStar 127SLT is a computerized telescope that offers a database of more than 40,000 stars, galaxies, nebulae, and more. The telescope locates your object with pinpoint accuracy and tracks it.
  • Compact and portable: This telescope for adults and kids to be used together is ideal for weekend camping trips or excursions to dark sky sites. Its compact form factor makes it easy to transport and assemble just about anywhere.Optical Tube:Aluminum
  • Maksutov-cassegrain optical design: The NexStar 127SLT is the second-largest in the SLT family. The 127mm aperture gathers enough light to see our Solar System and beyond. View Saturn’s rings, Jupiter’s cloud bands, and the Moon in brilliant detail.
  • Fast setup with skyalign: Celestron’s proprietary SkyAlign procedure has you ready to observe in minutes. Simply center any 3 bright objects in the eyepiece and the NexStar SLT aligns to the night sky, ready to locate thousands of objects.
  • Bonus free starry night software: The NexStar 127SLT Computerized Telescope includes a free download of one of the top consumer rated astronomy software programs for an interactive sky simulation.
