The researchers weren't necessarily looking for this neutron star. Rather, it was happenstance as they searched for gravitational waves."At Green Bank, we're trying to detect gravitational waves from pulsars," said Maura McLaughlin, study author and Eberly Distinguished Professor of physics and astronomy at West Virginia University. "In order to do that, we need to observe lots of millisecond pulsars, which are rapidly rotating neutron stars. This is not a gravitational wave detection paper but one of many important results which have arisen from our observations."They were able to measure its mass because of a white dwarf companion star that warped the space around both stars. This warping acted as a way to accelerate the pulsar's pulses through space. They could learn the mass of the white dwarf and neutron star this way through the "Shapiro Delay.""Neutron stars are as mysterious as they are fascinating," said Thankful Cromartie, a graduate student at the University of Virginia and Grote Reber pre-doctoral fellow at the National Radio Astronomy Observatory in Charlottesville, Virginia. "These city-sized objects are essentially ginormous atomic nuclei. They are so massive that their interiors take on weird properties. Finding the maximum mass that physics and nature will allow can teach us a great deal about this otherwise inaccessible realm in astrophysics."Due to their mysterious nature, astronomers still want to answer more questions about neutron stars and this unique one could help them. They want to know if crushed neutrons become a type of "superfluid," what the breakdown looks like and where the actual tipping point lies when gravity takes over."The orientation of this binary star system created a fantastic cosmic laboratory," said Scott Ransom, study co-author and an astronomer at the National Radio Astronomy Observatory. "Neutron stars have this tipping point where their interior densities get so extreme that the force of gravity overwhelms even the ability of neutrons to resist further collapse. Each 'most massive' neutron star we find brings us closer to identifying that tipping point and helping us to understand the physics of matter at these mind-boggling densities." 2221

The?Allied Pilots Association?(APA) and Lion Air's operational director claim Boeing's operational manual for the MAX 8 did not contain adequate information about the MCAS system."We don't receive any information from Boeing or from (the) regulator about that additional training for our pilots," Zwingli Silalahi, Lion Air's operational director told CNN on November 14. Both the pilot and co-pilot of Flight 610 were experienced, the airline has said, with 6,000 and 5,000 flight hours respectively.Boeing stood by the aircraft's safety record. "We are confident in the safety of the 737 MAX. Safety remains our top priority and is a core value for everyone at Boeing," a spokesperson said.The parents of one passenger is suing Boeing,alleging the 737 MAX 8 had an unsafe design. The suit alleges Boeing failed to communicate a new safety feature that hadn't existed in previous 737s.Boeing released an operational bulletin on November 6, a week after the crash, warning all airlines abou

The prosecution cited footage of Stockley rummaging through a bag in the back of the police vehicle. That was when Stockley retrieved the weapon, they argued. Prosecutors also pointed to the fact that Stockley's DNA had been found on the weapon. 245

The San Diego Association of Governments (SANDAG) announced the completion of the second bridge in the San Diego River Double Track project. Construction began in fall 2016, with the first bridge opening for rail traffic in 2018. 229

The study said 15,914 people died in motor vehicle crashes in August during a five-year span from 2012 to 2016, ranking it as the deadliest driving month of the year. Of the 15,914 deaths, 505 fatalities happened on Aug. 2.During August 2017, Floridians drove in the most congested traffic conditions of any state, said the study. Drivers in Florida spent 16.3 percent of their time idling in traffic last August. Congested traffic is the leading cause of crashes, said the report. Other leading contributing factors to crashes include hard braking and suddenly speeding up.Nationwide’s data said Friday between 9 a.m. and 4 p.m. is the most aggressive time of the week for drivers. During this timeframe, drivers’ habits show more instances of hard braking and faster accelerations than any other time of the week. 840
