What's Up This Week?
 
Hello skywatchers!

Spring skywatching is in full swing and this week offers a little bit of everything.

From a close pairing of the moon and the red supergiant Antares to the return of Saturn in the predawn sky and Venus climbing higher in the evening, there are plenty of reasons to look up. 

Elsewhere in this issue, we're showcasing a beautiful roundup of April's full moon rising around the world, along with a behind-the-scenes feature revealing how a single astrophotographer created the breathtaking space imagery seen in the end credits of Hail Mary and the story behind how it all came together.

Here's what to watch for in the nights ahead.

Clear skies,

Monday, April 6: Moon near Antares 
(Starry Night)
Monday, April 6: Moon near Antares 

The moon passes close to Antares, the red supergiant marking the heart of Scorpius. While the occultation favors southern skies, northern observers can still catch the pair low before dawn. 

 
Tuesday, April 7: Moon at apogee 
(Starry Night)
Tuesday, April 7: Moon at apogee 
The moon reaches apogee at 6 a.m. EDT (1000 GMT), appearing slightly smaller and dimmer. This softer light is ideal for spotting detail along the lunar terminator.
 
Wednesday, April 8: Saturn returns (predawn)
(Starry Night)
Wednesday, April 8: Saturn returns (predawn)
Saturn reappears in the morning sky, low on the eastern horizon about 30-60 minutes before sunrise.
 
Thursday, April 9: M13 in Hercules
(Starry Night)
Thursday, April 9: M13 in Hercules

Look northeast after 9 p.m. for M13, the Great Globular Cluster — one of the finest deep-sky targets, easily visible in binoculars. 

 
Friday, April 10: Last quarter moon & galaxies 
(Starry Night)
Friday, April 10: Last quarter moon & galaxies 
The moon reaches its last quarter phase, bringing darker evening skies. It is a great time to hunt galaxies like M81 and M82 in Ursa Major.
 
Saturday, April 11: Venus climbs higher 
(Starry Night)
Saturday, April 11: Venus climbs higher 
Venus crosses into the northern sky and becomes easier to spot after sunset, shining brightly low in the west.

Notable moon phase this week: Last quarter moon

The moon reaches its last quarter phase on April 10. At this phase, the moon appears half illuminated with its western side lit. It rises around midnight and lingers in the daytime sky. With less glare than earlier in the week, the evenings leading up to this phase offer improving conditions for spotting deep-sky objects like galaxies and star clusters.

Constellation spotlight:
 
UNIVERSE, UNSPECIFIED - 2025/04/02: (EDITORS NOTE: Image is a digital composite.) (EDITOR'S NOTE: Image is a digital composite.) Messier 81, in Ursa Major, is one of the most visible spiral galaxies in the sky. It forms a physical pair with its neighbor, M82, and is the dominant galaxy in the M81 group.
M81 is likely about 12 million light-years away, has a diameter of at least 70,000 light-years, and its mass has been estimated at around 250 billion Suns.
A few hundred million years ago, a close encounter occurred between M81 and its smaller neighbor, M82, during which the latter was dramatically deformed.
M81 is still gravitationally interacting with Messier 82. The interactions have stripped away some hydrogen gas, leading to the formation of filamentary gas structures in the group. In addition, the interactions have also caused some interstellar gas to fall into the center of Messier 82, leading to strong star formation activity.

Constellation spotlight: Ursa Major

This week, turn your gaze north to find Ursa Major, home to the famous Big Dipper asterism. Use the "pointer stars" at the edge of the Dipper's bowl to locate Polaris, the North Star. But don't stop there! Ursa Major also hosts a wealth of deep-sky treasures, including the galaxy pair M81 (Bode's Galaxy) and M82 (Cigar Galaxy), both excellent targets for binoculars and small telescopes under dark skies.
