12 posts held, back to 9 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 12 posts for this entry, the most recent from 31 July 2026. An engagement rate over an empty window would be a number about nothing.
207 reactions across 12 posts, in 7 distinct kinds. The most used accounts for 43.5% 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 12 of the 12 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 207 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 12 most recent posts we hold, published 9 July 2026 to 31 July 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.
A paid reaction is a reader spending Telegram Stars — bought with money — on a post by @openobservations. Telegram publishes the count on the public post preview alongside ordinary reactions, and this register reads it there. It is the only figure on this site that measures money moving rather than attention.
Stars are not reactions, and the two are never added. They are rendered in the same strip on Telegram and counted in the same shape, but one is a tap and the other is a purchase. The reaction totals and the engagement rate elsewhere on this page exclude every figure in this section, and no rate here is computed against a reaction count.
This is not revenue, and we publish no currency figure. What a Star costs a reader and what it pays a channel are different numbers, Telegram takes a share we cannot observe, and the terms have changed. Converting a Star count into money would be an estimate dressed as a measurement, so the count is where we stop.
Counted over the 12 most recent posts we hold for this entry, published 9 July 2026 to 31 July 2026. Star counts above 1,000 reach us in Telegram’s short form and carry the same three-significant-figure rounding as everything else on this page.
Друзья! Сегодня вечером встречаем поочередно восход Луны и Сатурна. Посмотрим, как терминатор (граница дня и ночи) медленно перемещается по Морю Кризисов - древнему ударному кратеру на поверхности Луны, погружая его в тень. Сатурн взойдет немного позже и будет доступен для наблюдения ближе к полуночи. Встречаемся на центральной площади Начало наблюдений в 22.45 Локация здесь

Это серебристые облака. Они формируются на высоте 80 километров на самой границе земной атмосферы. Видны они только летом, поскольку в это время года на такой высоте самые низкие температуры, что позволяет концентрироваться кристаллам льда. Серебристые облака образуют волокнистые структуры, которые довольно быстро меняют свою форму из-за постоянного движения. Они интересны тем, что светятся на фоне темного неба, пос…

Арт-объект "Послушайте!" Название работы отсылает к стихотворению В. Маяковского "Послушайте! Ведь, если звезды зажигают — значит — это кому-нибудь нужно?..". В своем произведении поэт использует символику звездного неба для обозначения высшего начала в жизни и ее метафизической цели. Маяковский трактует звезды в рамках гуманитарной парадигмы, наделяя их появление на вечернем небе особым, надматериальным значением.…

Друзья! Сегодня опять немного посмотрим Сатурн и остальное из доступного на том же месте. Начало в 00.10. Отпишитесь в комментах, кто пойдет, поскольку начинаем поздно и хотелось бы точно знать, имеет ли смысл ждать гостей)

Друзья! Приглашаем вас в субботу, 22 августа, в арт-кафе Бали, где пройдет наша лекция "Вселенная в объективе". На встрече за чаем посмотрим фотографии, вошедшие в историю астрономии, и поговорим об их научном, культурном и эстетическом значении для человечества. После лекции - наблюдения в телескопы Начало в 19.00 Локация здесь Вход свободный Изображение: Закат Солнца на Марсе. Снимок марсохода Spirit, 2005

Работа художницы Марии Колосковой, которую она создала для нашей выставки, посвященной теме космоса. Соотношение цветов отображает здесь процентное распределение массы во вселенной: белый - темная энергия, черный - темная материя, цветные элементы - обычное вещество, из которого состоит мир вокруг нас. Белый цвет символизирует недостаточность понимания в современной науке того, что представляет из себя темная энерг…

Showing the 12 most recent of 12 posts we hold for @openobservations. 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.
Stars beside a post are paid reactions — Telegram Stars, bought with money and spent on that post. They are a different unit from reactions and are never added to them, here or anywhere else on this page.
Republished by
Channels on the register that have forwarded this channel's posts into their own feed.
Republishes
Channels on the register whose posts this channel has forwarded.
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.
Named by 3 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.
Names
Channels on the register whose handles appear in this channel's posts.
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.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 4 September 2026 — this entry's latest reading, not the date you are reading this.
