Three Killed in Paris Shooting
A gunman in Paris, France has been apprehended after opening fire on Rue d’Enghien, a busy shopping street in Paris. The attack killed three people with one other in the hospital in critical condition and two with lesser injuries. Witnesses reported the shooter targeted a Kurdish community center as well as a restaurant and hair salon. There is no confirmed motive yet, however a Paris prosecutor reported the suspect in custody had been previously charged with racist violence in 2021, attacking a migrant camp in Paris with a sword. Anti-terrorism prosecutors are in contact with investigators, but there is no indication of terrorist motive. Paris police are advising people to avoid the area as part of the ongoing investigation.

Canada-United States
Winter Storm Brings Bitter Cold
Arctic storms are bringing dangerous impacts to Canada and the United States. Winter Storm Elliott, which has officially developed into a bomb cyclone, is already bringing blizzard conditions to the Great Lakes region after sweeping down through Canada, and is projected to bring continued dangerous weather for the eastern parts of both countries through the weekend. In the Appalachians and New England, strong wind gusts of up to 50 mph (80 km/h) have been reported. In response, airlines have canceled flights throughout the affected area. Beyond flights, many households in the United States have been experiencing blackouts, with power outages in North Carolina currently affecting over 150,000 people.

Space
Milky Way's Heart Discovered
Scientists with the Max Planck Institute for Astronomy (MPIA) have discovered a group of stars left over from the earliest history of the Milky Way, which some team members are referring to as the "poor old heart" of our home galaxy. Scientists determined the age of the stars by their metallicity - the amount of elements heavier than helium contained in the atmosphere of a star. Stars are massive nuclear fusion reactors, first compressing hydrogen atoms into helium atoms, however as stars age, the helium begins to be compressed into heavier elements. The presence and proportions of these heavier elements give off different spectrographic information detectable to scientists, and relative metallicity can be correlated to stars' varying ages. Using this information, aided by artificial intelligence (AI), scientists were able to identify the oldest stars in the galaxy, going back around 13 billion years.

Q: Of all the mountains that make up the Alps in Europe, which mountain is considered the most recognizable? (Hint: Each side of its peak points to one of the cardinal directions!)
A: Matterhorn
Matterhorn, meaning "peak in the meadows" in German, stands almost 15,000 ft (~4,600 m) tall on the Swiss-Italian border. The mountain formed millions of years ago when the African continental plate collided with the European plate, forcing the ground upwards, and the resulting pyramid-shaped peak aligned with the four cardinal directions - north, south, east, and west. The north side faces the Swiss Zermatt Valley, the south peak faces the Italian town of Brueil-Cervinia, the east faces Gornergrat Ridge in Switzerland, and the west overlooks the Swiss-Italian border. At the base of the mountain is an igloo resort, Iglu-Dorf, with interconnected rooms and tunnels, and home to the world's largest snow igloo. The first time Matterhorn was scaled to the top was in the summer of 1865. Out of the seven pioneers making their ascent, only three made it back, the other four in the crew fell to their deaths.
