Did you know? A large rocky body - known as #Theia - slammed into the early #Earth about 4.5 billion years ago. But where did Theia come from? A team of researchers in Germany and Chicago said that Theia likely originated closer to the sun than Earth. 🔭

This time of year is great for saying hello to everyone’s favorite #constellation: Orion the Hunter! Find #Orion now and enjoy it for months to come. No doubt, Orion is the easiest-to-identify of all constellations. Look for it in the eastern sky this month. 🌌🔭

If there's #life on #Mars today, scientists think it's likely underground. Researchers in China say they've found the 1st #caves on Mars potentially created by water. Could they be homes for life, now or in the past? 🦠🔴🔭
