The track will undergo what officials called "additional extensive testing" during the closure. The Stronach Group, the track's owner, announced late Tuesday evening it will conduct what it called "a comprehensive evaluation of all existing safety measures and current protocols," during the closure. 300

The White House on Monday will introduce the two turkeys up for a Presidential pardon this Thanksgiving — and will allow Americans to vote which for which one is declared the "National Thanksgiving Turkey."Last year, the Drumstick beat out Wishbone as the nation's Thanksgiving Turkey, beating out his buddy, Wishbone. President Trump later pardoned both turkeys, which now live in a farm at Virginia Tech in Blacksburg, Virginia.Watch the turkey introduction in the player above.     509

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 state auditor said Schwerman's backyard was overflowing with evidence. Many vendors had relationships with the district so he would have the items delivered to the maintenance garage and then he would take them to his house, authorities said.Schwermann has been indicted for theft in office and tampering with evidence, both third-degree felonies.  377

The shooting occurred just before 10 p.m. Sunday on the westbound side of SR-94 near Lemon Grove Avenue, according to California Highway Patrol officials. 154
