Millenia ago, #Euclid constructed surprisingly airtight, axiomatic proofs for his book "The Elements," which are still taught today.

Similar logical doctrines CAN be applied to the HDL domain to prove (or refute) the presence of certain bugs without testing every individual case by brute force!

Does knowledge by aquisition trump knowledge by acquaintance? The point being pointed to does not depend on Euclid’s definition of it having no parts; if the reason for its being means it cannot exist without dimensions, properties and dispositions. #Euclid #Acquisition #Acquaintance #Philosophy #ThePoint #DialecticPrinciple #Oppositions https://mathcs.clarku.edu/~djoyce/java/elements/bookI/bookI.html

Euclid scopre il quasar più antico dell'Universo

#euclid @[email protected] @[email protected]

Euclid dell'Agenzia Spaziale Europea ha scoperto 31 dei quasar più antichi mai individuati. Due di questi nuclei galattici, giganti e abbaglianti e alimentati da buchi neri gargantuescamente grandi, sono i quasar più precoci mai osservati nella storia cosmica.

What is new in the Universe, is actually very old!

The European Space Agency’s Euclid space telescope has discovered 31 of the most ancient quasars ever found.

Two of these galaxy cores EUCL J172902.75+641018.1 and EUCL J125308.55+705432.3 are powered by gargantuan black holes, and are the earliest quasars yet observed in cosmic history.

Both lie just over 13 billion light-years away, and emerged during the Universe’s first 670 million years – just 5% of its current age. https://www.esa.int/Science_Exploration/Space_Science/Euclid/Euclid_discovers_the_most_ancient_quasar_in_the_Universe #EU #Euclid #SpaceTelescope #Space #Universe #Astronomy #Quasars #BlackHoles #Galaxy #CosmicHistory

An article published in the journal "Astronomy & Astrophysics" reports the discovery of 31 new primordial quasars, including the two oldest known so far. A team of researchers used observations conducted with ESA's Euclid space telescope as part of the Euclid Wide Survey to find quasars we see as they were when the universe was no more than 800 million years old.

With this first collection, #Euclid starts dominating the search for early Universe #quasars. This is no wonder: Euclid's wide survey provides unprecedented sensitivity at wavelengths into the near-infrared, which are key to identifying these rare accreting early black holes.

Forecasts predict that in Euclid data even earlier quasars should be found: likely beyond z=8 (650 million years after the Big Bang) and possibly even z=9 (550 million years).

Euclid dell’ESA immortala il cuore affollato della Via Lattea

#euclid @[email protected] @[email protected]

La missione Euclid ha pubblicato la foto più dettagliata del centro della nostra galassia, nella luce visibile. Con oltre 60 milioni di stelle, offre agli scienziati la possibilità di confermare l’esistenza di eventuali esopianeti individuati in questa regione e di misurarne la massa sfruttando le minime variazioni della luce stellare nel tempo.

@cnes alors, pourquoi #Euclid a été utilisé pour faire cette image ?
Je suis super content de cette utilisation, mais je ne comprends pas l'intérêt autre que de communication. 😁

Le télescope spatial #Euclid vient de réaliser la plus grande image haute résolution jamais obtenue du cœur de notre galaxie en lumière visible. En seulement 26 heures d'observation, Euclid a assemblé une mosaïque couvrant une portion du ciel équivalente à plus de 20 pleines Lunes vues depuis la Terre.

A year ago, #Euclid's first small data release 'Q1' provided data for 63 deg² of sky to the world. Now an 'Astronomy & Astrophysics Special Issue' has been published with 41 articles about and around this release:

https://www.euclid-ec.org/q1-special-issue-aa/

Many of these articles were made public as preprints at the time of the Q1 release, but since then we added about a dozen extra, and they are now all peer reviewed. Open access, open science.

Last week, we announced that ESA and the Euclid Consortium released a massive image of the Milky Way's heart. This 'Q2' data release contains images of 60 million stars. A great primer on this image comes from the EC's Chris Pattison:
