CNN —A decade-long survey of the night sky has revealed a mysterious new type of star astronomers are referring to as an “old smoker.”These previously hidden stellar objects are aging, giant stars located near the heart of the Milky Way galaxy. This illustration shows an eruption occurring in the swirling disk of matter around a newborn star. They help the newborn star in the middle to grow, but make it harder for planets to form. Infrared images show a red giant star, located 30,000 light years away near the center of the Milky Way. Understanding how the old smokers release elements into space could change the way astronomers think about the way such elements are distributed across the universe.

Where This Summer Was Relentlessly Hot The planet just experienced its hottest months on record, and by a large margin, scientists said. Some areas, including northern Canada and some of Greenland, show temperatures more than 6 degrees Fahrenheit (3.3 degrees Celsius) above average. Phoenix, which is known for its extreme heat, shows temperatures more than 2 degrees Fahrenheit (1.1 degrees Celsius) above average. The global map spins to South America, where average daily temperatures were higher than normal for much of the continent. Areas of Sudan and Ethiopia show temperatures greater than 6 degrees Fahrenheit (3.3 degrees Celsius) higher than normal.

CNN —Parts of South America are sweltering under abnormally hot temperatures – despite being in the depths of winter – as the combination of human-caused climate change and the arrival of El Niño feed into extreme winter heat. “This temperature is the highest recorded in this period in all of Chile,” a spokesperson for the Meteorological Directorate of Chile told CNN. Ivan Alvarado/ReutersIn Argentina, some places reached highs of 38 degrees Celsius (100.4), according to the country’s national meteorological service. This smashed the previous record for that day of 24.6 degrees Celsius (76.3 Fahrenheit) set in 1942. For comparison, New Orleans’ average high the first week of February is also 18 degrees Celsius, and the city has never been above 28.3 degrees Celsius in the first week of February.
