🔭 Mercury, Moon, planets and meteors! In the night sky this April, the Moon makes its monthly rounds to pair up beautifully with several planets. A new Moon on April 20 may mean ideal conditions to spot the Lyrid meteor shower.
- From April 3-11, Northern Hemisphere observers can look low in the west after sunset for the best chance to spot Mercury
- Venus can be seen near the Pleiades star cluster April 11
- Find the Moon near Saturn in the east in the hours before sunrise on April 15-16. On April 25, the Moon and Mars pair up in the sky high in the West after dark
- The Lyrid meteor shower peaks on April 23, with best viewing between midnight and dawn
The Lyrids are named for the constellation Lyra, which is near the point in the sky where their meteors appear to come from, called the radiant. They're one of the oldest known meteor showers, with the first recorded sighting in China some 2,700 years ago. To observe them, find a comfortable spot away from bright city lights, get horizontal, and look straight up. You'll see the most meteors by looking slightly away from the origin point, which is near the bright star Vega.

Auroras are natural light shows caused by magnetic storms triggered by the Sun’s activity like explosive flares and coronal mass ejections (ejected gas bubbles). Solar winds carry the energetically charged particles from these events to Earth’s atmosphere.
When these particles seep through Earth's magnetosphere, a part of our atmosphere that protects us from solar and cosmic radiation, they cause substorms. These fast-moving substorm particles slam into our thin, high atmosphere, colliding with Earth's oxygen and nitrogen particles. As these air particles shed the energy they picked up from the collision, each atom starts to glow in a different color—causing the brilliant ribbons of light which weave across Earth's northern or southern polar regions.
Typically, auroras are visible closer to Earth’s poles, where the magnetosphere is generally weakest; however, when the Sun releases especially powerful solar storms, auroras can be seen further from the poles. Just that happened this past week when a powerful geomagnetic storm delighted skywatchers with auroras as far south as Virginia and Arizona!
Video description: The northern lights as seen from the International Space Station. The video begins with the green hues of the northern lights dancing across the skies of North America. The curvature of the Earth is visible where the auroras in the atmosphere meet the darkness of space. As the video continues it moves further southeast across North America, revealing the bright lights of cities across the midwest United States.
