Astronomers have detected the most massive neutron star ever, and it almost shouldn't even exist.Neutron stars are the smallest in the universe, with a diameter comparable to the size of a city like Chicago or Atlanta. They are the leftover remnants of supernovae. But they are incredibly dense, with masses bigger than that of our sun. So think of the sun, compressed into a major city.In the case of the newly detected neutron star, dubbed J0740+6620, it's 333,000 times the mass of the Earth and 2.17 times the mass of the sun. But the star is only about 15 miles across. It's 4,600 light-years from Earth.This is close to the limit of how much mass a compact object can contain before it crushes itself into a black hole.The neutron star itself is rapidly spinning, which is called a pulsar because they send out beams of radio waves from each magnetic pole. The beams mimic the sweeping motion of a lighthouse beam, hence the name "pulsar."Pulsars act like atomic clocks because they regularly pulse, so astronomers can use them to study space and time.The star was detected by the 1098

Apple is widely expected to unveil its latest lineup of iPhones at a closely watched media event on Tuesday.But don't hold your breath for an iPhone that's foldable, 5G capable or radically different from the models released last year. Here's what Apple is likely to announce instead:iPhone predictions: Apple will likely show off three new high-end iPhones — the iPhone 11 Pro, the iPhone 11 Pro Max and the iPhone 11 — replacing its XS, XS Max and XR models, respectively.Rumored features: The new phones may include a faster processor, improved Face ID and a new camera system with three cameras on the back. The devices will likely look nearly identical to last year.Software updates: Apple announced in June that iOS 13 will feature a dark mode to save on battery life, a way to silence unknown callers and a tool that allows you to swipe to type, rather than lifting your fingers.Other hardware products: Apple may also integrate artificial intelligence capabilities and built-in sleep tracking into the Apple Watch. The rumor mill also suggests updates for MacBooks, iPads and Apple TV hardware.What not to expect: A 5G iPhone. That will likely come in 2020. 1177

As unrest spread across dozens of American cities on Friday, the Pentagon took the rare step of ordering the Army to put several active-duty U.S. military police units on the ready to deploy to Minneapolis, where the police killing of George Floyd sparked the widespread protests. That's according to three people with direct knowledge of the orders who did not want their names used because they were not authorized to discuss the preparations. Soldiers from Fort Bragg in North Carolina and Fort Drum in New York have been ordered to be ready to deploy within four hours if called.The troops could be used in addition to 500 Minnesota National Guard troops called up on Thursday. 693

AT&T announced this week that its streaming TV service DirecTV Now has increased prices and reduced its offering of channels.When the service launched in late 2016, it was seen as an affordable alternative to cable. For those who signed up for the service in its early days, a monthly fee was good for nearly 100 channels. But the service's launch was plagued by sluggish and inconsistent service. But starting in April, the pricing and number of offerings will change. The cheapest option for DirecTV Now will be the DirecTV Now Max package, which offers 40 channels for a month. For more, consumers get 10 added channels, which includes Cinemax and regional sports networks. DirecTV Now's price increase is part of a trend of streaming services increasing prices. 793
