Is anybody home? Astronomers have pinpointed two planets orbiting a nearby star that meet pretty much every requirement for supporting life. They're almost exactly the same mass as the Earth, they are billions of years old (which means life could have had time to evolve), and they're orbiting their star at a distance that would support things like water flow and habitable temperatures.The two planets orbit Teegarden's star, an ancient star that is only 12-light-years away from the Earth. ("Only" is relative -- 12 light-years is equal to 70,540,000,000,000 miles.) Research on the planets and their sun, 621

Laverne Renz lives alone in her home near Pittsburgh. At 85-years-old, Renz is not as independent as she used to be, but she has plenty of energy.“I have to listen to her, or she’ll beat me up,” Renz jokingly said when asked about her caretaker, Rose Shenkel. The two have a playful relationship.But Shenkel is not always around, so Renz has a back-up caretaker.“Alexa, call Susie for me,” shouts Renz.She uses Amazon’s Alexa to make phone calls and to listen to her favorite music. Alexa is even setup to give Renz important reminders.“She reminds me when to take my medicine, when to eat my lunch. She reminds me of everything. She won’t leave me alone,” jokes Renz.But Shenkel said when she’s not there to keep Renz company, Alexa can step in.“It’s companionship for her. Artificial, but it’s companionship,” says Shenkel. “She spends a lot of time alone, so I think when Alexa comes on that perks her up, even when she wants to shut her up, it perks her up.”The technology can be more than just a voice to talk to. It’s also setup to be a lifesaver. 1065

It’s snow day in the nation’s capital. Washington, D.C. is just one of many places being hit by winter weather as Winter Storm Petra moves across the Midwest and eastern part of the country. Seven-year-old Elin Neuville and her father got the day off and took advantage of the snow by sledding all morning. But it wasn’t fun and games for many others. The weather went downhill overnight, bringing snow, sleet, and heavy rain across the country. More than 160 million people were impacted. The winter storm forced thousands of flights to be canceled, including more than 700 in and out of D.C. alone. Many passengers were left stuck at airports because of delays. “I've been up since about 5 or 6, just checking to see if my flight was going to be impacted and it wasn't. It wasn't until I got here it was delayed,” said one frustrated passenger. Flooding is a big concern in parts of the south. Nashville has already received more than a foot of rain. 966

It's looking more and more likely that the United States soon could face its first tropical threat in the young 2019 hurricane season.On Sunday, the National Hurricane Center increased the chance to 50% that a system could develop in the Gulf by the middle of the week. Depending on your computer model of choice, the ensuing system could pose trouble -- or worse -- from the Florida panhandle to southern Louisiana.While it's still too early to tell if this system will get strong enough to be named (that would be Barry, by the way), more interesting is "how" this could all come about.For the most part, meteorologists vigilantly scan the Gulf or Atlantic Ocean from June to November for signs that low pressure systems are developing with the potential to strengthen.Turns out that average date of 814
