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.

#Hubble in a death spiral that could end as early as 2028 without a reboost
The post on Bluesky by #astronomer #JonathanMcDowell is a stark reminder that Hubble is heading back to Earth, possibly sooner than previously thought, as its orbit decays.
Hubble was launched into #LEO in 1990, in bay of Space Shuttle Discovery. While it remains capable of pointing its instruments and returns breathtaking imagery over more than three decades in orbit, it cannot raise its altitude

Happy Space Science Saturday!
On April 3, 2026, Mercury will reach its greatest elongation west, appearing at its farthest apparent distance from the Sun in the morning sky. This is one of the best opportunities to spot the innermost planet, which is usually lost in the Sun’s glare.
You can start looking now through early April. Mercury will be visible low in the eastern sky shortly before sunrise and will continue to improve as it approaches elongation over the next week.
Because Mercury stays so close to the Sun, it can be tricky to observe, but this upcoming window offers one of the best morning viewing chances of the year.
Safety first: Never point binoculars or a telescope anywhere near the Sun, and do not try to observe Mercury while any part of the Sun is above the horizon.
