10 measurements spanning 32 days, net +14. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 1,484–1,507 and does not start at zero.

Engagement
18 posts held, back to 30 July 2026 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 2 pages of Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 18 posts for this entry, the most recent from 6 August 2026. An engagement rate over an empty window would be a number about nothing.
Reaction mix
36 reactions across 15 posts, in 9 distinct kinds. The most used accounts for 33.3% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 15 of the 18 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 36 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 18 most recent posts we hold, published 30 July 2026 to 6 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

۱۰ کتاب برای شروع نجوم؛ از اولین قدم تا درک بهتر کیهان
اگر بعد از دیدن مستندها دوست دارید نجوم رو جدیتر دنبال کنید، کتاب بهترین قدم بعدیه. این فهرست طوری چیده شده که از کتابهای ساده و عمومی شروع میشه و کمکم وارد مباحث عمیقتر میشه.
۱. کیهان (Cosmos) – کارل سیگن
اگر فقط قرار باشه یک کتاب بخونید، انتخاب همینه. کارل سیگن با زبانی ساده و روایتمحور، از تاریخ علم تا ستارهها، کهکشانها و جایگاه…
۵. The Planets
اگر به منظومه شمسی علاقه دارید، این مجموعه یکی از کاملترین گزینهها برای آشنایی با تاریخچه و ویژگیهای سیارههاست.
۶. Universe (BBC)
مستندی مدرن با تصاویر چشمنواز که چرخهی زندگی ستارهها و ساختار کیهان رو به شکلی ساده و دقیق روایت میکنه.
۷. Apollo 11
روایتی مستند از نخستین فرود انسان بر ماه، بر پایهی تصاویر آرشیوی واقعی و کمتر دیدهشده.
۸. For All Mankind
تجربهی مأموریتهای آپولو رو از زبان فض…

از کجا نجوم رو شروع کنیم؟
اگه به نجوم علاقهمندید اما هنوز مطالعهی جدی رو شروع نکردید، مستندها یکی از بهترین نقطههای شروع هستن. یه مستند خوب، علاوه بر انتقال مفاهیم علمی، تصویر روشنی از مقیاس کیهان، تاریخ اکتشافات فضایی و جایگاه انسان در جهان ارائه میده.
در ادامه، ۱۰ مستند پیشنهادی رو به ترتیبی آوردیم که از مفاهیم پایه شروع میشه و کمکم به موضوعات عمیقتر میرسه.
۱. Cosmos: A Spacetime Ody…
(پارت دوم)
● ممکنه که کیهان "تقارن C"رو نقض کنه.
تقارن C میگه که اگه یک ذره اسپین جهت ساعترو داره، پادذره هم باید همون اسپینرو داشته باشه.
در تعاملات ضعیف مثل فروپاشی رادیواکتیو، تقارن C نقض میشه یعنی ذرات و پادذرات، رفتار مخالف بهمدیگهای دارن.
● ممکنه که پروسههایی وجود داشته باشن در کیهان که تعداد باریونهارو عوض میکردن.
باریونها، ذراتی هستن که تقریبا هرچیزی که میبینیمرو تشکیل میدن مثل پروتونها و نوترو…

موضوع منتخب برنده:
"چرا جهان ما از ماده ساخته شده، نه پادماده؟ (اگه در لحظهی #مهبانگ، ماده و پادماده به مقدار مساوی تولید شده بودن، باید میلیاردها سال پیش همدیگه را نابود کرده باشن و چیزی جز انرژی باقی نمیموند. اما ما اینجاییم.) "
ما تا این لحظه، در کیهان، فقط مادهرو تونستیم تشخیص بدیم و در مقیاسهای بزرگتر، هنوز ندیدیم که پادماده، مادهرو نابود کنه و تا بحال، اجرام آسمانیایرو ندیدیم ک…
جوابهای سوالهای کوئیز رو میتونین در پستهای زیر پیدا کنین:
● شکر Erythrulose در کجا پیدا شد؟
● هدف ماموریت Dragonfly ناسا چیست؟
● بیشترین دمایی که سفینه آرتمیس ۲ درش آزمایش شد چقدر بود؟
● ماموریت آرتمیس ۲ چقدر طول کشید؟

Showing the 12 most recent of 18 posts we hold for @spaceastron. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Polls
The 4 polls we hold for this entry, as Telegram rendered them when we read the post. A poll’s figures keep moving after that, so each one is dated.
Shares as published. No per-option vote count is published by Telegram, so none is shown.
Percentages only — there are no per-option vote counts here, because Telegram publishes none. The public post preview gives each option’s share and a single voter total, and nothing else. Multiplying one by the other would produce a per-option tally that looks measured and is not: the shares are rounded to whole numbers before we ever see them. We print what was published and leave the column that does not exist empty.
The shares need not add up to 100. Rounding alone puts many polls at 99 or 101. A poll that allows more than one answer per voter runs well past 100 by design, and several here do. The bars are drawn against a fixed 100% track at each option’s own percentage rather than normalised to the total, so a poll that exceeds it shows that it does instead of being quietly rescaled.
Read from the 18 most recent posts we hold, published 30 July 2026 to 6 August 2026. Telegram labels each poll by kind — an anonymous poll, a quiz, a closed set of final results — and that label is reproduced rather than paraphrased.
Forward network
Republished by
Channels on the register that have forwarded this channel's posts into their own feed.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Mentions
Named by 4 registered channels — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
Appears in Telegram’s recommendations for other channels
The reverse of the list above, and a different kind of signal. This does not require this channel to have ever been asked about directly — each row below is a channel we DID ask Telegram about, whose Telegram-generated list happened to include this one. A channel can appear here with an empty list above it, because being named by someone else’s query is independent of having been queried itself.
کتابخونه صوتی @audiopersianlibrary · 39,806 Telegram ranks this channel #67 of 76 here — alongside 75 others — read 30 August 2026
This channel appears in 1 seed channel's Telegram-generated recommendation list in total. Each is Telegram’s list for THAT channel, not this one — see how this is measured.
