Happy Space Science Saturday!
The Bubble Nebula, shown in this image, is also known as NGC 7635. It is approximately 7 light years across and the star forming this nebula is about 45 times more massive than the Sun. The bubble’s surface is expanding outward and meets with cold gas on one side which causes an asymmetry that makes the star appear off-centre.

Happy Space Science Saturday!
The Lyrids meteor shower peaks on the night of April 22–23, bringing up to 18 meteors per hour! One of the oldest recorded meteor showers, the Lyrids come from debris left behind by Comet Thatcher. While the radiant is in the constellation Lyra, meteors can appear anywhere in the sky. So find a dark spot, give your eyes time to adjust, and look up.
For the best views in Toronto, head out after midnight when the sky is darker and the radiant is higher.

Happy Space Science Saturday!
As part of NASA’s Artemis program, Artemis II recently completed its historic crewed lunar flyby, the first since the Apollo era, sending astronauts around the Moon and back to Earth. This mission is testing critical systems needed for future lunar landings, including Artemis III.

Happy Space Science Saturday! The Cat's Eye Nebula, also known as NGC 6543, was one of the first, and one of the most complex, planetary nebulae ever discovered! It is estimated to be 1,000 years old. Planetary nebulae are named for their round shape, which made them appear to look like planets when viewed through early telescopes, but they are actually expanding gas thrown off by stars in their final stages of evolution.
