Today Chandra is studying Terzan 5, a globular cluster of stars located about 19,000 light-years from Earth. Globular clusters are roughly spherical collections of tens of thousands to millions of stars that are tightly bound by gravity and found in a wide variety of galaxies.โจ
Lyrebirds are Australian birds most notable for their superb ability to mimic natural and artificial sounds from their environment (and other environments, if it's the case)

Today Chandra is pointed into Draco. Nearby in the sky is NGC 6338 โ 2 groups of galaxies slamming into each other at about 6.4 million kilometers per hour. One of the most violent collisions of this type ever seen, it's producing temperatures near 20 million degrees Celsius.๐ฅ
