"Great Spring Triangle visible this weekend in North America."

This weekend offers a great opportunity for stargazers in North America, as new spring constellations emerge in the night sky. The vernal equinox has brought equal amounts of day and night, marking the start of spring. Sky-watchers can look forward to seeing the Great Spring Triangle, formed by three bright stars: Arcturus, Spica, and Denebola. Arcturus is a red giant star located about 37 light years away, while Spica is further at 261 light years. The moon will be in its last quarter phase tonight, lighting up the constellation Sagittarius. This means that the moon won’t rise until midnight, allowing for around 10 hours of dark skies ideal for stargazing. One highlight this weekend is the constellation Corona Borealis, also known as the "Northern Crown." There may be a chance to witness an event called a nova. A dim star in this constellation, known as T Corona Borealis or the "Blaze Star," is expected to explode on March 27. If it does, it could shine up to 1,000 times brighter. For those trying to find Corona Borealis, look towards the high northwestern sky after sunset. Find the Big Dipper, then follow its handle to locate Arcturus. From there, look for the bright star Vega rising in the east. Corona Borealis is positioned between these two stars. Remember to check local star maps for more specific viewing information. Enjoy clear skies and happy stargazing!
