Generally (without considering many other factors which may be involved) the closer the latitude is to the poles [i.e. the absolute value of the latitude is greater], the longer the sunset. (see table at this pdf (last page) and this piece of mail for more factors) Therefore: Latitude at NY, NY = 40.7 Latitude at Jerusalem, IL = 31.78 NY, NY is closer to ...

First, it may not be valid to assume that creation was bound by the laws of science as we now understand them. Why should we assume that the very first plants grew by photosynthesis in the same way that plants do now? Or if we do, why not assume that the primordial light created on the first day was enough to produce this effect? But setting all that ...

I think I remember learning in elementary school that the Moon and the Sun had, as they have now, the same angular diameter when viewed from the Earth, and they also had coronas of equal size, so their total sizes, including coronas, were equal. When the Moon complained about their equality, literally in terms of a "crown" (which a corona resembles and which ...

Rambam, Hilchos Yesodei Hatorah Chapter 3. From Chabad.org Halacha 1 The spheres are called the heavens, the firmament, the habitation, the skies. There are nine spheres. The closest sphere is the sphere of the moon. The second sphere, which is above it, is the sphere which contains the planet Kochav (Mercury). The third sphere, which is above ...

The Shulchan Aruch (OC in the 220's) lists a bunch of natural phenomenon that get special blessings including: Strong rains after an extended drought Blossoming fruit trees Meteors Comets Earthquakes Lightning Thunder Strong winds Seas Rivers (possibly only the four mentioned in Genesis 2) Uniquely tall mountains Uniquely tall cliffs Deserts Rainbows The ...

Orchot Rabbeinu 1 p 93 quotes the Steipler that no bracha is said on a solar eclipse because it is a Siman Ra', a bad omen as outlined on Sukkah 29a and in this question. In the book Shaar HaAyin (7:6 footnote 13), the author quotes the Shevet HaLevi as leaving the issue in doubt.

The explanation referenced in my answer here (I'm still looking for the underlying source - it must be in some maamar or sicha) seems to indicate that the "diminishment" is closer to your second possibility - though focusing not so much on the moon's waxing and waning, but on the fact that it is not self-luminous but receives its light from the sun. (Is ...

I wonder if maybe they misinterpreted the source from which they got the times. Suppose that the original said "ליל שני" or the like; that would properly mean "the night leading into Monday" (i.e., Sunday night), but the printers of your chumash may have misunderstood that to mean Monday night. Out of curiosity, then, can you post several months' worth of ...

For question 1: The blessing is addressed to Hashem ("Who created the heavens with His word... Blessed are You, G-d, Who renews the months"), not to the moon. Where's the avodah zarah there? It's no different than the blessings on other natural phenomena, such as rainbows, notable mountains, etc, where we look at the object while praising Hashem. [That ...

The MA holds that we split up the 12 hours of a day from Alot HaShachar (the beginning of day) to Tzeit HaKochavim (the end of the day). The Gra holds that the 12 hours are split from sunrise to sunset independent of what is considered day or night. All agree that noon must be when the sun is highest in the sky. (This can be proven from the gemara that says ...

This might simply have been a confusion of units. Sizes.com claims that a Russian verst is equal to 500 sazheni, but a Moscovy verst is 1000 sazheni. The sazhen was fixed at 7 English feet (2.134m) in both systems way back during the 1700s in Peter the Great's rule. In 397:1, the Aruch HaShulchan says that specifically, he is talking about the Russian ...

YDK's answer perpetuates the common misconception that it is the ellipticity of the Earth's orbit that causes the latest sunset not to fall on the longest day. But this is not true. The primary cause of the phenomenon is the obliquity of the Earth's axis, that is, the fact that the Earth is tilted with respect to its orbit around the sun. The ellipticity ...

Per Torah.org Contemporary poskim debate whether taking a photograph of the sun or the moon is similar to drawing a flat image. Several rule stringently on this issue. There is an Igros Moshe Orach Chaim 5 - 9:6 that discusses this, however I am not able to find it online. Minchas Yitzchok 10:72 seems to prohibit it, however says it may be ...

I could theorize that according to R. Firrer, the 'halakhic Earth' would be defined as anywhere that one is still subject to the Earth's gravitational field. Actually reading the article, however, implies that either 1. as soon as something is not touching Earth, it is no longer governed by its halachos (which, as you point out, is ridiculous) or 2. anything ...

The Rambam himself addresses your question. He writes the following in Moreh Nevuchim regarding the science in the Gemara: Moreh Nevuchim (3:14): אל תדרוש ממני להתאים את כל ענייני האסטרונומיה שהם ציינו אל המצב כפי שהוא, כי המתמטיקה היתה לקויה באותם זמנים. והם לא דנו בזאת מבחינת שהם מוסרים אמרות אלה מפי הנביאים, אלא מבחינת שהם היו חכמי אותן תקופות ...

The Gemara in Chagiga 16a mentions not staring at a rainbow (for too long). It represents (is similar to?) the glory of Hashem and (along with not staring at the king) is considered disrespectful to enjoy the view. כל שלא חס על כבוד קונו רתוי לו שלא בא לעולם: מאי היא ר' אבא אמר זה המסתכל בקשת רב יוסף אמר זה העובר עבירה בסתר מסתכל בקשת דכתיב {יחזקאל א-כח} ...

A quick search of discussions on the web seems to point to there being no particular bracha and that Oseh Ma'aseh B'reishit is not called for, for a solar eclipse. As a kal vachomer, I would say that if there is nothing said for the still infrequent but more spectacular solar eclipse, then for the transit, why would there be? This site suggests other textual ...

While researching another answer, I came across a comment by R' Yonasan Eibeschutz (in Yaaros Devash), that the Gemara's expression ליקוי חמה isn't referring to eclipses at all, but to sunspots. (He doesn't seem to say what ליקוי לבנה might mean in this context. But I guess, according to his explanation, that it would also mean some kind of short-term ...

2) We say Just as I can not touch you so should my enemies not be able to touch me. ... and (b)We debunked the idea that we can't touch the moon in 1969. It's poetry, not a statement of technological capability. If you stand outside looking at the moon, hundreds of thousands of miles away and yet a distinct object, with the possibility of enemy attack ...

Tikkunei Zohar (introduction, 4b, passim) associates these with the verse (Ex. 3:15, זה שמי לעלם וזה זכרי לדר דר - "This is My name forever, and this is My remembrance for all generations." The reference there is to the Four-Lettered Name of Hashem, י-ה-ו-ה. Each of the terms in that verse ("My Name" and "My remembrance"), then, relates to one half of that ...

Aish pathways says the blessing Oseh Ma’aseh Veraishit is said upon seeing spectacular mountains, deserts, lightning, earthquakes, hurricanes, astronomical phenomena, and impressive bodies of water. The Wikipedia entry for Aurora is titled “Aurora (astronomy)”. Thus the bracha Oseh Ma’aseh Veraishit seems right. But CYLOR. Edit: In the light of ...

As far as I know, "Shachar" - is a name of a star. When it get placed somewhere in the sky - halachikaly the day begins. I've just found out here that Venus is named Shachar.

R' Gil Student cites the Ibn Ezra “[T]he beginning of each individual’s year is from the moment he was born, and when the sun returns to the same point at which it was earlier, the person completes one full year” (['Iggeret HaShabbat, chapter 1]p. 21). Nevertheless, insofar as there are halachic implications, R' Student understood the Bar Mitzvah to ...

To solar cycle represents continuity and consistency. The lunar cycle represents rise and fall, והחיות רצוא ושוב. The two cycles don't inherently mesh, and it takes the actions of people (as represented by Beis Din which sets the leap year) to combine the two. See here for a similar expression of this idea. In terms of lessons in Avodas Hashem, there are ...

Probably (though you can never be sure with questions like these) you're referring to Rashi's comments on "כי היא חכמתכם ובינתכם לעיני העמים", "this shows your wisdom and understanding in the eyes of the nations" (Devarim 4:6), where Rashi quotes the Gemara in Shabbos (75): איזו חכמה ובינה שהיא לעיני העמים הוי אומר זה חישוב תקופות ומזלות What is ...

from here, quoting R. Isaac of Homil (a hebrew biography can be found here): The moon, when she was first created, was a glistening jewel. She did not merely reflect light, but rather transformed it and brought out its inner beauty, much as a precious stone glistens with a secret, hidden light all its own. In her own way, the moon was greater than the ...

Rashi in Bereishis, chapter 1, Verse 14 on "והיו לאתת" mentions this issue of a bad omen from the eclipse. He says: והיו לאותות: כשהמאורות לוקין סימן רע הוא לעולם, שנאמר (ירמיה י ב) מאותות השמים אל תחתו, בעשותכם רצון הקב"ה אין אתם צריכין לדאג מן הפורענות: When there is an eclipse of the luminaries it is a bad sign for the world, as it is said: "Do ...

The verse immediately following Joshua's miracle states: וְלֹא הָיָה כַּיּוֹם הַהוּא, לְפָנָיו וְאַחֲרָיו, לִשְׁמֹעַ יְהוָה, בְּקוֹל אִישׁ: כִּי יְהוָה, נִלְחָם לְיִשְׂרָאֵל.‏ And there was no day like that before it or after it, that the LORD hearkened unto the voice of a man; for the LORD fought for Israel. (Joshua 10:14) So it would seem it ...
