AMTK 11 and 76 leading Amtrak Train 59, the southbound City of New Orleans through downtown Brookhaven, Mississippi with extra single level Horizon cars for a Polar Express Christmas Train on its way down to New Orleans on Sunday, December 2, 2018.
The train had to stop at the train station and do an inspection on one of the axles on AMTK 76 due to it having a wheel slip that was picked up on the defect detector near Milepost 772 up at Beauregard in Copiah County. It took about a 15 to 20 minute long delay before they got going again.

Tucked away in ESO’s La Silla Observatory in Chile, this humble telescope is one of three in the groundbreaking French ExTrA project, discovering stars with Earth-like planets in the Milky Way and probing their environments. But how do these triplets tell us so much about systems many light-years away?
When a planet orbiting its host star passes between it and the Earth, it blocks a small but detectable amount of light, similar to how the Moon blocks light from the Sun in a solar eclipse. ExTrA targets red dwarf stars, which are smaller than our Sun. This means that Earth-sized planets will block a larger proportion of their total light and are therefore easier to find.
Even better, ExTrA observes these red dwarfs across a range of colours to learn more about a planet’s atmosphere, using a method called spectroscopy. The best contenders can be studied in greater detail with ESO’s Very Large Telescope and the upcoming ESO’s Extremely Large Telescope, both located further north, to tell whether they may be viable to support life. So ExTrA may find new candidates for our first galactic neighbors!
