What's Up This Week?
Hello Skywatchers!

This week brings a mix of midnight and pre-dawn delights. It begins with Tuesday's third quarter moon, perfect for deep sky observing in the evenings. Then, early risers are rewarded with graceful planetary meetups: a crescent moon pairs with Saturn and Neptune on Thursday, followed by a stunning trio with Venus joining the scene on Friday. Whether you're a night owl or an early bird, the skies have something special in store.

Here's what to watch for this week.

Clear skies,

Tuesday, May 20 — Third Quarter Moon

Thursday, May 22 — Crescent Moon Meets Saturn and Neptune
(Starry Night)
Early risers will see the waning crescent moon near Saturn in the eastern sky. Neptune is nearby, but a tough catch unless you're in southern latitudes with darker skies.

Friday, May 23 — Moon Between Venus and Saturn
(Starry Night)
A stunning trio! The crescent moon shines between Saturn and dazzling Venus before dawn. Try capturing the scene with a scenic foreground. Venus lingers longest as sunrise approaches.

Notable Moon Phases This Week

My favorite moon phase to look out for this week will be the third quarter moon on May 20. It will rise around midnight local time and set around midday so you'll be able to catch a glimpse of it in both the night and daytime sky.

NASA resurrects Voyager 1 thrusters after 20 years
(NASA)
NASA engineers have miraculously revived the Voyager 1 interstellar probe's backup thrusters - components that hadn't been used since 2004 and were long considered fully defunct. This remarkable feat became necessary because the spacecraft's primary thrusters, which control its orientation, have been degrading due to residue buildup. If its thrusters fail completely, Voyager 1 could lose its ability to point its antenna toward Earth, therefore cutting off communication with Earth after nearly 50 years of operation.

Norway is the third country to join the Artemis Accords so far in 2025. A signing ceremony to welcome Norway took place today (May 15) at the Norwegian Space Agency in Oslo, with Norway's Minister of Trade and Industry Cecilie Myrseth signing on behalf of the Norwegian government.

Payload fairing fail delays Australia's 1st orbital rocket
(Gilmour Space Technologies)
We'll have to wait a bit longer for the first-ever launch of an Australian orbital rocket. Queensland-based company Gilmour Space had aimed to debut its Eris rocket today (May 15), but a problem with the vehicle's payload fairing scuttled that plan. "Last night, during final checks, an unexpected issue triggered the rocket's payload fairing. No fuel was loaded, no one was hurt, and early inspections show no damage to the rocket or pad," Gilmour Space said via X this afternoon.

Scientists witness highest-energy 'ghost particle' ever seen
(KM3NeT)
Earlier this year, an underwater detector in the Mediterranean Sea found the most energetic neutrino to date. And scientists are still talking about it because, well, this discovery could be a really big deal. Not only could this neutrino, also known as a "ghost particle," have been fleeing a gamma-ray burst or a supermassive black hole, but it could also have been produced by an ultra-powerful cosmic ray interacting with the cosmic microwave background (CMB).
