⬆️ ⬆️ ⬆️ E adesso qualche notizia in più sulle Perseidi, le "stelle cadenti" di agosto: non si tratta di stelle che cadono ma di minutissima polvere di cometa, originata dalla Swift-Tuttle, una cometa periodica che passa ogni circa 133 anni (l'ultima volta nel 1992). A ogni passaggio la cometa, composta da roccia e ghiaccio, si consuma e lascia andare nello spazio gas e polveri che rimangono disseminate lungo l…

Engagement
20 posts held, back to 6 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 1 page 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 20 posts for this entry, the most recent from 7 August 2026. An engagement rate over an empty window would be a number about nothing.
Reaction mix
1 reaction across 1 post, in 1 kind.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| ❤ | 1 | 100.0% |
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 4 of the 20 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 1 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 20 most recent posts we hold, published 6 July 2026 to 7 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.

⬆️ ⬆️ ⬆️ E adesso qualche notizia in più sull'osservazione con lo Smart Telescope: Nel giardino dell'Osservatorio osserveremo tutti insieme proiettati su uno schermo alcuni oggetti del cosiddetto "cielo profondo" (ammassi stellari, nebulose, galassie) che solitamente non sono alla portata di cieli inquinati dalle luci come quelli dei centri cittadini o delle immediate vicinanze. Ci riusciremo, ovviamente in caso…

Showing the 12 most recent of 20 posts we hold for @osservatoriorighi. 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.
