Calendars, coincidence, and play

Sacred Space Astronomy avatarPosted on September 3, 2020 by Br. Guy ConsolmagnoSeptember 3, 2020
This entry is part 14 of 54 in the series And Then I Wrote

And then I wrote… it’s September and so the 2021 Calendars are available! Here are two more reflections from calendars of years past… And since these are meant to support our Calendar guild (click here to get a calendar!) I am not putting them behind the usual firewall… 2019 Calendar There are many coincidences in astronomy. The Moon’s size and location allows it to exactly eclipse the disk of the Sun. The visual juxtaposition of the stars Alcor and Mizar in the Big Dipper’s handle drew the attention of early telescopes to discover that Mizar was actually a double star (whose separation is just right for those early telescopes). The shapes of nebulae remind us of horses’s heads or dumbbells. And of course it’s mere chance that the nebulae themselves happen to be not only scientifically interesting, but also remarkably beautiful.  There’s no cosmic significance to it, really. Just coincidence. And yet…  In December 1988 I spent a week at the Jesuit retreat … Continue reading →

2021 Vatican Observatory Calendars

Sacred Space Astronomy avatarPosted on September 1, 2020 by Bob TrembleySeptember 1, 2020

The Vatican Observatory calendars have been a tradition since the year 2000! Each month, the calendar features a beautiful photograph of the heavens by some of the leading astrophotographers from around the world. The 2021 calendar features the works of: Mark Hanson, Stellar Winds Observatory, USA Damian Peach, UK Bernard Miller, USA R. Jay GaBany, USA Robert Gendler, USA Josef Pöpsel, Stefan Binnewies, Capella Observatory, Germany Johannes Schedler (chart32.de), Panther Observatory, Chile/Austria Bernhard Hubl, Austria Dario Giannobile, Italy Anthony Ayiomamitis, Greece J-P Metsavainio, Finland Tony Hallas, USA Adam Block, Steward Observatory – University of Arizona, USA   Here’s a taste of the beautiful images of the heavens in the Vatican Observatory 2021 calendar: For 21 years, the Vatican Observatory Guild has helped to support and promote our work through the distribution of the Official Calendar of the Vatican Observatory. Each contribution of $25 or more entitles a Guild Member to receive or give a copy of the 2021 Calendar.

Reflections on a calendar

Sacred Space Astronomy avatarPosted on August 27, 2020 by Br. Guy ConsolmagnoAugust 27, 2020
This entry is part 15 of 54 in the series And Then I Wrote

And then I wrote… in September our 2021 Calendars become available! What I suspect most people don’t notice is that on the back of every calendar is a little reflection that I write, based on a suggestion — often just a word — from Dr. Brendan Thomson, the volunteer who does all the legwork of putting these incredible calendars together. Over the next three weeks I though I would run the texts of these reflections from the calendars going back to 2016. If I can find earlier calendars I may add to this list! And since these are meant to encourage people to join our guild and get a calendar, I am not putting them behind the usual firewall… 2017 Calendar Why does the Vatican support an astronomical observatory? It’s a common question we get asked, and there are many simple answers.  The Observatory is a way of showing the Church’s support for science. It’s a way of demonstrating that, … Continue reading →

Own your own space-time continuum!

Sacred Space Astronomy avatarPosted on September 3, 2019 by Br. Guy ConsolmagnoSeptember 5, 2019
This entry is part 44 of 63 in the series Diary

So, last week Pope Francis met in a private audience with the sixteen members of the Vatican Observatory. We presented the Pope with the published proceedings of a recent workshop we’d held on Gravitation and Black Holes — how we understand the fabric of space and time warped together in the deepest regions of space. That meeting had included Nobel Prize winners and other notables from the field; the Pope had met them, too. But another gift that we gave the Pope tells a deeper story. We also offered him a copy of our 2020 astronomical calendar. Every year, the Vatican Observatory Foundation publishes a calendar full of glorious astronomical images and marking significant dates in the history of our science. It’s a way of raising money to help support our telescope and our outreach efforts. But hundreds of these calendars are also given away, for free, to inmates in San Quentin and other prisons. All the prisoners have to do … Continue reading →

From the Tablet: Why is Ash Wednesday So Late This Year?

Sacred Space Astronomy avatarPosted on March 6, 2019 by Br. Guy ConsolmagnoFebruary 5, 2019
This entry is part 66 of 191 in the series Across the Universe

This column ran in The Tablet for the new year’s issue of 2008, when Easter occurred remarkably early, on March 23. It was relatively early in 2016, on March 27th, when we ran it here. This year, it’s about as late as it can be! Early or late, the explanation is the same… and so probably worth running again. Why is Ash Wednesday so late this year? Contrary to popular conception, the Vatican Observatory doesn’t set the date of Easter. (We don’t cast horoscopes for the Pope, or evangelize UFOs, either.) But since Pope Gregory’s reform of the calendar in 1582 marked the beginning of the Vatican’s support for astronomy, we have a historical connection. Our calendars have always been marked by a confusion of days, planets, and gods. Even today, our week begins with the Sun’s day, followed by the Moon’s day and ending with Saturn’s Day. The month (think, “moonth”) was originally based on the 29.5 day period of the Moon, … Continue reading →

A note on the date of Easter

Sacred Space Astronomy avatarPosted on April 2, 2018 by Br. Guy ConsolmagnoApril 2, 2018
This entry is part 28 of 63 in the series Diary

Horst Rademacher,  a seismologist at U C Berkeley, wrote to friends of mine there last weekend, asking about the date of Easter: May I bother you with a question, which is probably trivial for astronomers like you to answer. However neither Peggy nor I could find an answer anywhere. Here is the question: Tomorrow (Apr 1) is Easter. According to the classic definition Easter always falls on the first Sunday after the first full moon after the vernal equinox. That makes sense, because today is full moon, which is the first full moon after the beginning of spring. And tomorrow is Sunday, hence Easter. However, today’s full moon occurred at 5:37 am PDT. Let’s assume, the full moon would have occurred at 5:37 pm PDT. Applying the definition above from a purely California perspective, tomorrow would still be Easter. However, if we were in the Netherlands, in Germany or in the Vatican for that matter, this assumed full moon would … Continue reading →

Across the Universe: Redating Easter?

Sacred Space Astronomy avatarPosted on January 18, 2018 by Br. Guy ConsolmagnoMay 30, 2018
This entry is part 160 of 191 in the series Across the Universe

This column first ran in The Tablet in January 2016 The archbishop of Canterbury Justin Welby has recently [2016] announced discussions to redefine the date of Easter. Pope Francis and various leaders of Eastern churches have also expressed interest in a common date that all churches would celebrate together. Easter was originally the Sunday following Passover, the first full moon of the Hebrew year. But the start of the Hebrew year varied from year to year. Jewish months, 29 days long, mirror the phases of the moon, and so every three or four years an extra month is needed to keep that lunar calendar in phase with the seasons. After the destruction of the Temple in AD 70, there was no central Jewish authority to determine when to add that month. Instead, Jews of the Diaspora relied on a Greek formula (devised in 432 BC by Meton) to add seven intercalary months over a repeating 19 year cycle. It was … Continue reading →

Calendars!

Sacred Space Astronomy avatarPosted on September 1, 2017 by Br. Guy ConsolmagnoMay 19, 2018
This entry is part 29 of 63 in the series Diary

Happy September the first… and happy Calendar Day! Yes, the official Vatican Observatory Foundation calendar is now available for sale: These calendars have been a tradition for more than ten years. Every month has an excellent astrophotograph, donated to us for our use, by some of the best amateur astrophotographers in the world. The 2018 calendar features work by Damian Peach from the UK (who did the cover photo above), Bernard Hubl from Austria, J-P Metsavainio from Finland, Adam Block from the University of Arizona… and more. Twelve… no, make that, fourteen fantastic images. (Counting the cover, and January 2019.) The calendar itself contains a delightfully eclectic selection of astronomically significant dates. And probably one or two typos, even though Dr. Brendan Thomson (who puts this together for us every year) and I must have proofread it at least three times each. Tell us of a typo and I will send you a cookie. Update: the 2018 calendars are no … Continue reading →

Across the Universe: Fast changes

Sacred Space Astronomy avatarPosted on June 22, 2017 by Br. Guy ConsolmagnoMay 30, 2018
This entry is part 130 of 191 in the series Across the Universe

This column first ran in The Tablet in June 2013 Summer began [in 2013] on Friday morning, 21 June, at 5:14 am GMT…in the northern hemisphere, of course; south of the equator, it’s winter. [The summer solstice 2017 in Northern Hemisphere occurred at 4:24 am GMT on Wednesday, June 21.] This definition is based on the precise orientation of the Earth in its orbit. The Earth is tilted relative to its orbit, and like a gyroscope its spin axis stays pointed in the same direction, year round. In a convenient coincidence for navigators, our north pole is pointed near the star Polaris. Polaris is not directly above the Sun; it’s directly above Earth’s tilted spin axis. In June, the Earth is in the part of its orbit where it’s on one side of the Sun, and Polaris is on the other side. The northern half of the Earth, tilted towards Polaris, is also tilted towards the Sun; that’s why it gets warmer. The … Continue reading →

2016 Calendars are available!

Sacred Space Astronomy avatarPosted on July 29, 2015 by Br. Guy ConsolmagnoJuly 29, 2015
This entry is part 17 of 63 in the series Diary

  Every year, the Vatican Observatory Foundation publishes a calendar featuring fantastic astronomical images from amateurs around the world… and noting dates of particular interest to astronomers. They can be purchased online here… This year’s calendar is out, and it looks great. (OK, so as proofreader I missed a couple of glitches, which immediately made themselves obvious as soon as I opened up the printed version. Nothing as bad as a couple years ago when we got Galileo’s birthday wrong!) On the back, I always write a pithy little paragraph or two that nobody reads. As a freebie for readers of The Catholic Astronomer, here’s what I put there this year: A few years ago, a couple of cosmologists who styled themselves as atheists attempted to show that there was “no need for God” to start the universe, at the moment popularly known as the Big Bang. They proposed thatthat a quantum fluctuation in the zero-energy vacuum field of the … Continue reading →
