Actual Astronomy - The Observer's Calendar for April 2026

Author: 365DaysOfAstronomy.org April 2, 2026 Duration: 23:03

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan who enjoy teaching astronomy classes and showing the public views through their telescopes. actualastronomy@gmail.com

 

This month in episode 528 we talk about 3 Comets, two of which may end up being very bright. We also touch on some colorful double and carbon stars. There are many spring spirals we help listeners find as well as the Lyrid Meteor shower. This month the Moon pairs with Spica, Antares and the planets and at mid-Month a very young moon is visible for some listeners.

 

Gamma Leonis - Colorful double star

02 - Full Moon - Spica and Moon less than 4° apart

03 - Morning Targets:

- Mercury Greatest Elongation 28° from Sun in morning sky - Spring elongations are a disappointment for Mercury

- Long Period Variable star max for R Serpentis

05 - Spot Sirius unaided eye before sunset this week. 88 Leonis colorful double star

06 and later - NGC 2903, large 9th mag. spiral in Leo

M48 - 6th mag. open cluster well placed at the meridian

Moon and Antares at dawn less than 4° apart

08 - NGC 3521 - well placed 9th magnitude spiral galaxy in S. Leo

09 - Carbon Star TU Geminorum is best

10 & later - Last Quarter Moon and Lunar X visible and 10th magnitude comet hanging out in Ursa Major

Mid-April - Moon, Mercury, Neptune, Mars, Saturn all congregate in morning sky - they are LOW

17 - New AND ***** Very Young Moon visible 14.5hrs old for us here in Canada, 6th magnitude so a real challenge but west of us esp. West coast it'll be 17hrs old… that's very doable

18 - Venus and Moon under 5° apart

22 - Lyrid Meteors - ZHR 18 - best in pre-dawn skies

23 - Last quarter Moon & Hipparchus ray visible on Moon

24 - Mons Pico & Pico Beta (the "Brothers Pico") visible south of Plato

Long period variable carbon star SS Vir @ 11:00 pm

25 - Moon occults Regulus this evening, 6:45pm for extreme S Canada & USA

25 - Eastern Mare 9:00 pm & Eyes of Clavius 9:00 pm

26 - Lunar Straight wall

Imagine a daily conversation about the cosmos, where each sunrise brings a fresh perspective from a different corner of the globe. That’s the essence of The 365 Days of Astronomy. Born from the spirit of the 2009 International Year of Astronomy, this enduring project has evolved into a genuine community effort, releasing a new episode every single day. You won’t hear the same host each time; instead, the microphone passes to astronomers, educators, enthusiasts, and scientists, each sharing their unique passion and expertise. This structure means the tone and topic can shift wonderfully from one day to the next-you might delve into the mechanics of a black hole on Tuesday and then explore ancient celestial myths on Wednesday. The consistent thread is a shared wonder for the universe, presented in accessible, bite-sized pieces. Managed by Avivah Yamani and edited by Richard Drumm, this daily podcast is a production of the Planetary Science Institute, sustained by listener support. It’s a calendar of the cosmos, offering a daily moment of reflection and discovery that proves you don’t need a telescope to have your perspective shifted. Tuning in regularly builds a habit of cosmic curiosity, connecting the vastness of space to the rhythm of our own days.
