Aug 30 - Tracking Star Families, Hurricane Dorian

August 30 Tracking Star Families, Hurricane Dorian by:

A face-on view of star families - sibling stars born from a single cloud of gas - in our Milky Way galaxy, within 3,000 light-years of our sun (center of image). The Milky Way is 100,000 light-years wide. Stars in clusters today appear as dots. Co-moving groups - stars born together and still moving together in space - appear as thick lines. The diagram is based on data from the astoundingly useful second data release of the European Space Agency's Gaia mission. Read more.

Gaia tracks sibling stars in Milky Way Rather than leaving home young, as expected, star siblings are more likely to stick together in long-lasting, string-like star groups, according to a new study of data from ESA's Gaia spacecraft.

The new grant will boost Arecibo's ability to search for and analyze these objects - called NEOs - with the goal of protecting Earth. It comes on the heels of a $12.3M grant earlier this month, which was aimed in part at fixing damage to Arecibo's big dish from Hurricane Maria in 2017. Read more. What we're reading    From Associated Press … Florida braces for Hurricane Dorian Puerto Rico and the U.S. Virgin Islands got lucky as Dorian brushed past the islands leaving relatively minor damage. However, the National Hurricane Center said the Category 2 storm is expected to strengthen into a potentially catastrophic Category 4 with winds of 130 mph (209 kph) and slam into the U.S. on Labor Day Weekend, somewhere between the Florida Keys and southern Georgia - a 500-mile (805-kilometer) stretch that reflects the high degree of uncertainty this far out.

Year's closest supermoon today Today - August 30, 2019 - presents the closest new moon of the year, exactly a fortnight (about 2 weeks) before the year's farthest and smallest full moon on September 14, 2019.
