In Historic Test, US Navy Shoots Down an Intercontinental Ballastic Missile
“In a historic test, a U.S. Navy guided missile destroyer shot down an intercontinental ballistic missile (ICBM) warhead aimed at a patch of ocean off the Hawaiian Islands,” reports Popular Mechanics: Once the missile launched, a network of sensors picked it up.

Does Jupiter’s moon Europa have geysers? If so, what’s their source?
If watery plumes do burst from Europa’s surface, they might originate not in the moon’s underground ocean, but instead in pockets of brine trapped in the moon’s crust. If that’s so, it could be a source of frustration for those who want to probe Europa’s ocean for possible life. Source: https://earthsky.org/space/jupiter-moon-europa-plumes-salty-water-in-crust…

Are there active geysers at Enceladus’ north pole?
Water-vapor geysers erupt from cracks at the south pole of Saturn’s moon Enceladus. Scientists using Cassini data now have evidence for fresh ice at the moon’s north pole, too. Could it be more geysers for this fascinating ice moon? Source: https://earthsky.org/space/fresh-ice-enceladus-north-pole-geologic-activity…
