SUMMARY:Next Generation of Io Science Workshop
DESCRIPTION:The goal of this workshop is to bring together interdisciplinary scientists to discuss outstanding science questions about Io — the most volcanically active world in the Solar System\, yet fundamental questions persist regarding its origin\, evolution\, present-day activity\, dynamic atmosphere\, and its complex interactions with the rest of the Jovian system. Io’s extreme activity makes it an important analog for understanding processes relevant to the early Earth and Moon\, and other tidally heated bodies across the cosmos. \n

SUMMARY:Lyrids Meteor Shower Peak
DESCRIPTION:Best seen from Northern Hemisphere\, with a lower hourly rate in the Southern Hemisphere\, Lyrids seem to stream from the Constellation Lyra. They actually derive from the debris trail of Comet C/1861 G1 Thatcher\, which has a period of 415 years. Can be “fireball” bright but usually lack persistent trains\, they travel ~49km/second and have a maximum rate (ZHR) of 18 per hour.
