What the Earth belongs to is not only the Milky Way, but also a “monster” in the galactic world of extremely terrible proportions..
The bright band we still see in the sky is called “Galaxy” The entire galaxy that contained Earth was once thought to have this name. Milky Way, or Milky Way.
It is a spiral galaxy with a disk of light approximately 100,000 light years in diameter, belonging to the “monster” in the galactic world and reached this formidable size by swallowing many other galaxies.
However, studies in recent years have gradually proven this The Milky Way is actually much bigger with incredibly expansive structures outside the stellar halo called “Galaxy” that we still see.
Halo
The Milky Way is not only the “Milky Way” in our imagination, which has the shape of a thin disk, shining with dense stars, but is also surrounded by a halo composed of 2 inner and outer layers, this which can cause the actual diameter of the entire galaxy to extend to 2 million light years – (nh: UCSC/NASA/ESA/STScI).
One of these mysterious things is Hello Hellothat’s to say The halo surrounds the main light disk. Recently published research from the University of California, Santa Cruz (UCSC – USA) showed another surprising point: There’s more than just an aura.
According to Sci-News, the authors used data from the Next Generation Virgo Cluster Survey (NGVS) mission, led by Canada-France-Hawaii Telescope (CFHT) and identified 208 variable stars not located in the main stellar disk, but located in the halo.
More shocking, they are incredibly far from each other, with a distance from the center of the Milky Way ranging from 65,000 to 1.05 million light years.
This showsthe residence of stars in the Milky Way must be a disk with a diameter of up to 2 million light yearsalthough only the middle part of the disk, which is much denser in stars than the surrounding part, can be seen as a band of light coming from Earth, or a disk of light if observed from a planet in another galaxy .
These data also provide valuable information about the halo, a very faint structure, almost invisible and difficult to observe.
“We can use these variable stars as reliable trackers to determine distance. Our observations confirm theoretical estimates of halo size” – said Dr. Yuting Feng from UCSC, a member of the research team.
With this result, the complete Milky Way should have a diameter of up to 2 million light years. Thus, it seems to extend to the neighboring giant galaxy, Andromeda.
Perhaps these two galaxies have no distance because Andromeda is also a galaxy in the “monster”, can also have an open halo like the Milky Way.
This shows Milky Way and Fairy – Hey “monster” expected to collide violently within the next 2 million years – can actually touch each other in the present. The next two billion years is just the distance it takes for the two main bright disks to come together.
The Milky Way and Andromeda galaxies once swallowed up many other small galaxies and grew peacefully, reaching a size that is among the giants of the galactic world to this day. However, their collision is expected to cause great damage to both, as they are both equally giant, in which the Earth is in danger of being thrown out of the sky. “living area” of the solar system.
