So any object closer than 32.6 light-years has an apparent magnitude brighter than its absolute magnitude. For any object farther away, the absolute magnitude is brightest. — Michael E. Bakich ...

In many astronomy textbooks magnitude "bins" usually categorize star brightness. Any star that, for example, falls between magnitude 1.50 to 2.49 would be designated as "second magnitude." ...

The race to connect the world through satellite internet has created an unexpected casualty: our view of the cosmos. A new ...

In astronomy, the apparent magnitude scale allows us to compare how bright stars and other celestial objects appear in the night sky. While this scale uses negative numbers to indicate brightness, ...

Scientists largely use the moment magnitude scale to categorize earthquakes’ strength and size in a way that’s more accurate than the long-used Richter scale, the US Geological Survey says.

The scale has no upper limit, but no fault long enough to generate a magnitude 10 earthquake is known to exist, according to USGS. In some cases, earthquakes can be so small as to have a negative ...

Under 5.0 magnitude: These tend to be I-V on the MM scale. Anything in this intensity range does not generally cause considerable damage. On the higher end, shaking may be felt by many, and ...

What does “moment magnitude” mean, ... The moment magnitude scale, as it is known, replaced one developed by an American seismologist, Charles Richter, that was used until the 1970s.
