Detail. JWST (NASA, ESA, CSA, STScI, D. Milisavljevic (Purdue University), T. Temim (Princeton University), I. De Looze (University of Gent))'s NIRCam image: Cassiopeia A (Cas A) in in near-infrared light. Red, green, and blue were assigned to 4.4, 3.56, and 1.62 microns. (image released December 10, 2023)

That's more than just a pretty picture. Well, part of a pretty picture.

It's our latest look at the Cassiopeia A supernova remnant. Webb's high-resolution cameras are showing details that scientists have never seen before....

...That's what I started talking about this week.

But the Cassiopeia A supernova's underwhelming appearance, or maybe non-appearance, reminded me of famines, coffeehouses, and other malign menaces.

So here's what I had, Friday afternoon:

More at A Catholic Citizen in America.

(Latest NIRCam image from Webb Telescope: highest resolution look so far at the supernova remnant Cassiopeia A. I also talk about coffeehouses.)

The Memorare

By Helen Gonsalves -

This popular prayer, a favorite of many Catholics, dates back to the 15th century and takes its name from the first Latin word of the prayer, "memorare," which means "remember." The Memorare is of unknown authorship, although it has been attributed to St. Augustine (354-430), St. John Chrysostom (c. 347-407) and, with more reason, to St. Bernard of Clairvaux (c. 1090-1153). St. Bernard's sermons on Mary were famous, and it was his Cistercian monks in the monastery of Citeaux in the 12th century who popularized the name "Our Lady" for Mary. The Memorare has also been attributed to the French cleric Claude Bernard (1588-1641), known as the "poor priest" of Paris, whose homilies contain passages that echo its words. No matter who wrote this prayer, it was Father Bernard who did much to popularize it, teaching it in hospitals and prisons, where Mary's intercession was effective in working miracles of grace. The first manuscript of the Mem

'Greater Love: Richie Fernando SJ', a joy-filled Filipino missionary

 I haven't been able to post for more than a week as I was giving an eight-day directed retreat to eight sisters of the Missionaries of Charity near Manila. While I had some access to the internet it was rather slow. I had intended to make a post here on the murder of Fr Fausto Tentorio PIME , a 59-year-old Italian priest, in the Diocese of Kidapawan, Mindanao, on Monday 17 October. I will save that post for a later date. As I was looking for a video about Father Fausto I came across one about Brother Richard Michael 'Richie' Fernando SJ, a Filipino Jesuit scholastic who died while trying to prevent a troubled and disabled young man in Cambodia from throwing a grenade. That was in 1996 - on 17 October. Father Fausto gave his life exactly 15 years later. I remember the mixture of sorrow and pride I felt when I read of the death of Brother Richie, pride as a missionary in the Philippines that a young Filipino seminarian had given his life so spontaneously in order to sav

Why Modesty Is Not Subjective

Hi there, ya'll!  The modest fashion world is one very diverse place.  Even among Catholics, the definition of "modest apparel" can vary greatly from person to person.  Recently I joined a Facebook group that advertised itself as a haven for Catholic women of all ages to share ideas for modest style and makeup and was hoping to learn more about modesty from my fellow Catholic sisters.  After a few days of being a member, though, I sadly left the group feeling a bit discouraged.  No two members seemed to agree on ANY aspect of modesty whatsoever, and the prevailing theme of the whole group was that modesty is subjective, it means something different for each woman and each woman gets to decide what she considers is "modest".  One woman very emphatically declared that she wears bikinis every summer to the beach and doesn't feel that this violates the virtue of modesty in the least.  The same woman also announced that she was never going to caution her d
