In 1990, its primary mission over, Voyager 1 was instructed to point its camera at Earth, or the Pale Blue Dot, 6 billion kilometers away. VOYAGER 1 has been beaming data to Earth since 1977.

Cause of Elevated A1c Levels. The higher your blood sugar levels and the longer your blood sugar remains high, the more excess sugar is present in the blood and the more opportunities this excess sugar has to bond to hemoglobin.
For individuals who have not been diagnosed with diabetes, higher-than-normal hemoglobin A1c values in the range of 5.7 percent to 6.4 percent may indicate an increased risk for developing diabetes. A hemoglobin A1c level above 6.5 percent will generally lead to a diagnosis of either type 1 or type 2 diabetes.
