About Nights on Earth

Hello, I'm Phil Mosby and I created Nights on Earth.

Photo: Hanging one of my hexagon clusters at the JWST Mission Operations Center, my proudest moment!

I am an astro/landscape photographer and fine-art print maker by trade, but I'm also an amateur space enthusiast, and a programmer who has been writing code and creating websites for over 20 years, professionally and for my own projects.

I have been taking photos of the night sky professionally for over 7 years, however it wasn't until 2021 that I finally created the first version of my Nights on Earth Wall Calendar & Stargazer's Guide to the Night Sky, a project that I had been dreaming about and planning for many years.

The calendar was a big hit with both space and photography lovers and quickly gained a small local following. I was thrilled with the reception, but I always knew that there was much more potential to the project than a static calendar calibrated to my home town. I had to find a way to generate a custom calendar for each user, using data calibrated to their location, to give it the maximum amount of value.

Many years of toil and thousands of lines of code later, I am thrilled to finally be offering the 2025 version of my Nights on Earth calendar with astronomical times customized to each user's location!

In the process of developing and designing the custom calendar software, I also started creating this website, with the intention that (almost) all of the same information that is available in the printed calendar should also be freely available online. I am very proud of what it has become, and excited to continue developing it over the coming years.

If you'd like to support this project, please consider purchasing a custom 2025 Wall Calendar calibrated to your lcoation anywhere on earth, alongside 13 gorgeous nightscape or deep space photos! They make awesome gifts for any space lover, and the proceeds are what make it possible for me to spend my time creating things like this website and my nightscape photos. Thank you to all who have purchased a calendar or print over the years I couldn't do this without you!

If you have any feedback or questions, feel free to reach out to phil@phil.camera.

Credits, Further Reading, and Thanks

Nights on Earth is powered by a hand-curated database of astronomical events that I've been compiling for the last 4 years, alongside real-time data from several free and paid APIs or generated on the fly based on the best available calculations.

You'll see links to the websites that I use to research this information throughout the calendar, those links will lead to more specific information about the astronomical events that they're related to. Every one of these websites is worth bookmarking and thoroughly perusing.

The websites, tools, and services that have been most instrumental to the research and development of this project are:

I happened on this calendar from a Facebook ad and bought a five pack for our sons and their in-laws as well as one for me of course.

I thought she would enjoy the astronomical data, and she did! Great service too...

Bought a Night Sky calendar for a friend who lives in the Texas Hill Country, where "the stars at night are big and bright". I thought she would enjoy the astronomical data, and she did! Great service too, when I first ordered it went to my old address (my bad probably) and Phil responded quickly and sent me another.

Thank you, Read MoreRead Less

Marilyn T., Beaumont, Texas, January 2024

And many of my clients love learning about the month’s astrological events at a glance.

I love this calendar! The previous inspirational quote calendars in my work space have been replaced every year now with your calendar. Nothing quite reminds of us of the majesty of life as the Milky Way over our usual earthly views. And many of my clients love learning about the month’s astrological events at a glance. I use past years’ images to frame as gifts and decorations. Thank you for the incredible work you put into the photography and information!

Much gratitude. Read MoreRead Less

Beautiful work, great print quality--just an exceptional calendar. Read MoreRead Less

Julie Gilson, 07/13/2023

I love astronomy and it's so satisfying not having to look up on Google about the day

This year has been eventful and I've never used a calendar before this year. It's nice to look back and see those events. I've been able to plan my days better. Even the little things like knowing when to take my dog out before it gets dark. I love astronomy and it's so satisfying not having to look up on Google about the day, it's right on the calendar. The pictures are beautiful and the random facts that I've added too my arsenal daily is satisfying. Read MoreRead Less

I love the layout of each day and the facts, and most of all the photos!

Your calendar is the most amazing calendar I've ever owned. I love all things to do with outer space and I've always especially loved keeping track of meteor showers and other space events.

With your calendar, I don't even have to look up dates or anything! They're just right there for me to be excited about. I love the layout of each day and the facts, and most of all the photos!

You take astonishing photos my friend, and I get excited whenever I have to flip the calendar to a new month and see another beautiful photo!

I am so excited to order next year's! Keep it up! Read MoreRead Less

Thank you so much for taking the time to do this. Your photos are amazing.

My son was just telling me to check and see if you were going to make one for 2023! We both really enjoyed your 2022 calendar, even though we don’t have darkness in the summer where we live. Thank you so much for taking the time to do this. Your photos are amazing. Read MoreRead Less

Joleen R., Facebook Comment, 10/25/2022

I have the 2022 calendar and I love it!

I have the 2022 calendar and I love it! The pictures are amazing and all of the astronomical info is super helpful. I use it to plan camping trips around the best stargazing times and to plan daily outdoor activities since it gives sunrise / sunset times. I will definitely be ordering a 2023 for myself and a few more for Christmas gifts. Read MoreRead Less

This will be my third, and I use it daily as my astro bible!

Just a quick note of thanks for the work I know you put into your fabulous calendar! This will be my third, and I use it daily as my astro bible! I've only been shooting nightscapes for a couple years, so your work is invaluable to me. Thank you for your commitment to this wonderful and beautiful resource! Read MoreRead Less

TR Barnard, 10/20/2022

This IS the night sky calendar you're looking for!

Holy cow! This is one beautiful piece of form and function! Every page is elegantly laid out with gorgeous imagery and loads of useful night sky condition information! All calendars have moon phases, but this one clearly and conveniently indicates a waning moon with a clever dark sky graphic on the appropriate days, making optimal dark sky viewing sessions easy to plan at a simple glance! Very cool! 😎 Upon closer inspection there is sun & moon, rise & set times for everyday. Meteor showers, conjunctions, and eclipses all there. Even planet AND Milky Way visabilty! Whoa! Creator really went above and beyond with this one! Maybe too much so as it continues FULLY ILLUSTRATED into first quarter of 2022! You really get more than your money's worth on this one. Only reservation I have would be I wish it were a little bigger, maybe 14x14". Text is a bit small and hard to read for us older folk and images really deserve to be that much more showcased. Really hope this calendar series continues because it's my new go to! Great job, Phil Mosby. You are a rock Star! Read MoreRead Less

Amazon User, 1/1/2021

The pictures in this calendar are works of art

You don't have to be an astronomy fan to enjoy this calendar. Every single photo is amazing. If you do want to know what there is to see in the night sky that can be answered by this calendar too. I highly recommend this for yourself and it also makes a great gift. Read MoreRead Less

Amazon User, 11/2/2020

Awesome & Perfect gift!

These calendars are beautiful and educational! They have a ton of info about star gazing, but also artistically captures the night sky and Tahoe landscape—seriously, what could be better? I have several pieces from this artist, but having a calendar is like having a new piece of art each month. This year all my family members are getting one for x-mas! Read MoreRead Less
