As to the above drama about mixing measuring units, the article says:
These images are also at least twice as sharp as what the Hubble Space Telescope (HST) can make because the 6.5m Magellan telescope is much larger than the 2.4m HST.
So there you go. Both measurements in Imperial European Units.
But then I read on, and was pretty stoked to see them discovering things like this.
MagAO was then used to map out all the positions of the brightest nearby Orion Trapezium cluster stars and was able to detect very small motions compared to older LBT data, a result of the stars slowly revolving around each other. Indeed, a small group of stars called Theta 1 Ori B1-B4 was proved to be likely a bound “mini-cluster” of stars that will likely eject the lowest mass star in the near future (see figure 4). This result has just been published in the Astrophysical Journal.
Nice! I'd love to see a time-lapse video over the course of the next million years watching this black sheep star get flung out of its little flock.
