Rambam repudiates astrology, writing that only fools believe in astrology (Hil. Akum 11:16): וּדְבָרִים הָאֵלּוּ כֻּלָּן דִּבְרֵי שֶׁקֶר וְכָזָב הֵן וְהֵם שֶׁהִטְעוּ בָּהֶן עוֹבְדֵי כּוֹכָבִים הַקַּדְמוֹנִים לְגוֹיֵי הָאֲרָצוֹת כְּדֵי שֶׁיִּנְהֲגוּ אַחֲרֵיהֶן. וְאֵין רָאוּי לְיִשְׂרָאֵל שֶׁהֵם חֲכָמִים מְחֻכָּמִים לְהִמָּשֵׁךְ בַּהֲבָלִים אֵלּוּ וְלֹא ...

Although rabbinic literature has yet to discuss death on Mars, the issue of being wholly buried underground, and the various complications to that happening (e.g., state requirements for burial in a coffin, a corpse under water, a buried corpse with limbs above ground, etc.), have been discussed. My theoretical answer depends on the work of the Rambam, the ...

It says in Sanhedrin 59b כי הא דרבי שמעון בן חלפתא הוה קאזיל באורחא, פגעו בו הנך אריותא דהוו קא נהמי לאפיה, אמר: (תהלים ק"ד) הכפירים שאגים לטרף. נחיתו ליה תרתי אטמתא, חדא אכלוה וחדא שבקוה. איתיה ואתא לבי מדרשא, בעי עלה: דבר טמא הוא זה או דבר טהור? - אמרו ליה: אין דבר טמא יורד מן השמים. בעי מיניה רבי זירא מרבי אבהו: ירדה לו דמות חמור מהו? - אמר ליה יארוד ...

The Shulchan Aruch in Yoreh Deah 179 siff 1 says we may not ask astrologers or use lotteries (to figure out the future). The Ramma quoting the Beis Yosef explains the reason is the Torah says תמים תהיה עם ה׳ אלהיך. In the next siff, the Ramma informs us from tshuvos Rashba (hamiyuchos liRamban) that if someone is somehow aware that a certain act is ...

Rashi on the Gemara that says אין מזל לישראל (Shabbos 156a), says: אין מזל לישראל - דעל ידי תפלה וזכות משתנה מזלו לטוב There is a modern Jewish hashkafa that the Zodiac can have an effect on our lives, but we have the ability to "get out of it". אין מזל לישראל means that Jews can be beyond their mazal, and are not bound to it.

In regards to time bound mitzvos in general Rabbi Menahem Kasher ruled that “The situation on the moon [or Mars] is equivalent to the north and south poles; therefore posit a 24-hour day, with alternating periods of 12 hours day and 12 hours night regardless of the presence or absence of light from the sun”. quoted here. The same would presumably be true ...

I'm not aware of any references in the Chumash itself, but the only two passages in the entire Tana'kh that may be relevant to your question, to my knowledge, are (JPS): Yeshayahu 40:22 "It is He that sitteth above the circle of the earth." (Rashi links this verse to 44:13, which speaks of a carpenter using a "compass") Iyov 26:7 "He stretcheth out the ...

In the linked article, Rabbi Aryeh Kaplan sources and discusses opinions on both sides of the argument, bringing various proofs and questions. Chasdai Crescas says aliens can exist, Yosef Albo said there cannot be any other beings with free will, apparently the only objection with believing in aliens centers around this issue of free will. Rabbi Kaplan also ...
