Because 2020 was not so ‘unprecedented’, astronomers have learned that the Earth was actually thought to be about 2,000 light-years closer to Sagittarius A * supermassive black hole at the center of the Milky Way galaxy.
After all, our solar system scientists are hitting through space at seven kilometers per second rather than counting.
These new releases are thanks to a new and improved map of the Milky Way that was published this week and is based on observations collected over the past 15 years from the Astronomy Project of Japan.

A light-year equals 9.5 trillion kilometers, so while it may seem like it may end at the beginning, scientists insisted that Sagittarius A * really has no cause for alarm about the Earth’s archeological proximity.
Instead of spelling out impending doom, new modeling allows scientists to pinpoint the Earth’s position in galaxies with greater accuracy.
Our newly plotted Milky Way is the result of observations of telescopes across Japan, forming the radio astronomy project ‘Vera’. Founded in 2000, Vera means VLBI (very long baseline interferometry) exploration of radio astrology.
The project created a super-resolution resolution of 10 micro-arcseconds using ‘interferometry’ techniques to collect data from multiple telescopes across Japan – in other words, focused enough to identify a coin on the moon’s surface.
Japan’s National Astronomical Observatory on Thursday revealed that, by its own astronomers and other groups, a “Location and velocity map” Which they counted as the center of the galaxy.

Astronomers say the galactic center is 25,600 light-years from Earth – about 2,000 light-years from the International Union of Astronomical Union’s official distance of 2,700 light-years, which it was located in 1975.
And as the decline continued in 2020, the new map also led astronomers to discover that the Earth was actually rotating the center of the Milky Way at a slower speed of 220 km / s than 227 km / s.
Vera researchers are now trying to create more detailed maps of the region around the central supermassive black hole using telescope data from Japan, South Korea and China.
