SpaceX hauled a classified payload into orbit for the U.S. government’s spy satellite agency Wednesday from Vandenberg Space Force Base in California, accomplishing another successful launch and landing on the second of three Falcon 9 rocket missions planned this week.
In February 2016, scientists with the Laser Interferometer Gravitational-Wave Observatory (LIGO) confirmed the first-ever detection of a gravitational wave event. Originally predicted by Einstein’s Theory of General Relativity, GWs result from mergers between massive objects – like black holes, neutron stars, and supermassive black holes (SMBHs). Since 2016, dozens of events have been confirmed, opening a new window to the Universe and leading to a revolution in astronomy and cosmology.
North Korea released some pictures they say come from their recent missile test. The missile they tested—the intermediate-range Hwasong-12—can reach the U.S. territory of Guam. According to most North Korea observers, the country hopes the tests will bring the U.S. back to the negotiating table.

Stars form inside vast collections of molecular hydrogen called molecular clouds, sometimes called stellar nurseries or star forming regions. Instabilities in the clouds cause gas to collapse in on itself, and when enough material gathers and the density reaches a critical stage, a star begins its life of fusion.
