Tomorrow, 23 May, 12:00 CEST, #ESA and the @ec_euclid will present 15 papers, including first #astronomy results:
5x #ESAEuclid reference papers about the main mission, the instrumentation, and related cosmological simulations
10x Early Release Observation #science papers, ranging from ... near to far
At the same time ESA will make 5 new ERO images public and the underlying science images. This programme was observed before the start of Euclid's main survey.
1112 authors for a space mission 🛰️ reference paper seems ... adequate 🤷🏽😯😁
We, the @ec_euclid will publish five main reference papers aimed at the astronomy community about the #ESAEuclid mission, the #Euclid instruments, both cosmology and other astronomy science possibilities, as well as the cosmological simulations used to test all procedures.
Available coming Tuesday, 23 May, 12:00 CEST (and on arXiv a few hours later). Stay tuned!
Expect new images and first science results from #ESAEuclid coming Thursday, 23 May. Five new stunning images, first ten science papers plus five #Euclid reference publications.
There will be broadcast by #ESA as well as press and paper releases by ESA and us. Stay tuned!
What is #ESAEuclid? It's a physics experiment and an #ESA space mission 🛰️ - but foremost it's a project imagined, designed, built, and operated by more than 2000 scientists, engineers, and technicians 👩🔬 👨💻 👩🔧.
We are now starting a series of #blog-posts showcasing a cross-section of the people behind #Euclid
You might recently have heard about ice buildup on #ESAEuclid's mirrors? 🧊 This was expected from experience with previous missions also for #Euclid and "de-icing" procedures were developed before launch and now refined. They involve warming up mirrors by a few 10°C. 🌡️
#ESA has now carried out the first de-icing campaign - and Euclid gained 15% of sensitivity within a few minutes. ✅
All the background, links to #ESA info, and an interview here:
#Euclid is a #space#telescope 🛰️ to escape #Earth's atmosphere, absorbing infrared-radiation and creating wobbly images. But space also has "weather". Given the currently active #sun 😎 and warnings of "geomagnetic storms" here's an intro blog post into "space weather" 🌪️ and how it affects the #ESAEuclid satellite.
We wish everyone around the globe a good start into 2024. The closing year 2023 marked a central milestone for us, the successful #launch and #commissioning of #ESAEuclid.
2024 will surely provide new challenges, but foremost the start of our #science sky surveys! In the next 12 months #Euclid will observe more than 2000 square degrees of the sky with hundreds of millions of #galaxies and #stars. The data floodgates will open - and amazing science will result!
Wow, a week ago #ESA released the first full-colour images from our #ESAEuclid mission. We ourselves are still impressed, but apparently so were others 😯. We collected a number of media reactions on our website:
Today I'm attempting #Heidelberg-#Madrid by #rail in one day. 6 trains from #tram to #TGV. Made train no 1 at 6:39. ETA in Madrid is 23:45.
Biggest challenge might be the regional train to Mannheim. Due to illness of personnel at least 1 of the 3 trains I could take simply isn't running, which means that one of the others will be crowded and hence delayed ...
And if you want to know what work lies behind creating our #ESAEuclid first full-colour images - and actually all science images in the future - here's an explainer video from our Youtube channel:
Now that our own excitement 🥳 about the #ESAEuclid Early Release Observation images, well, not subsides, but has changed from "we'll soon have great images" to "I want to go back to ESA Sky and browse some more", we notice that we aren't alone.
#ESA's webstory about the image release has already had more than 250,000 visitors, let's see if (or when 😉) we'll exceed the #JWST first image release (300,000):
🔭 🌌 Die ersten Bilder der ESA-Mission #Euclid sind da! 🤩
#ESAEuclid liefert erstmals Aufnahmen aus den nahegelegenen Regionen unseres Universums und beweist damit: Sonde, Teleskop und wissenschaftliche Instrumente bereit sind für die Erforschung der Dunklen Materie und Dunklen Energie im Weltall. 🛰️
Deutschland ist über die Deutsche Raumfahrtagentur im DLR an der Mission beteiligt.
< 14 hours to go before we see the first full-color images from the ESA Euclid space telescope.
In its quest to study dark matter, Euclid will make a 3D-map of the cosmos by observing billions of galaxies out to 10 billion light-years, across more than a third of the sky.
5 images will be released in a ceremony that will include discussions by mission scientists at ESA’s Space Operations Centre in Darmstadt, Germany.
Another remarkable image from the Euclid release is this one of spiral galaxy IC 342. Nicknamed the ‘Hidden Galaxy’, it is difficult to observe because it lies behind the central disc of our Milky Way galaxy, 11 mil light years away, obscured by intervening dust, gas and stars.
Observation time: 5 hours
Instruments: VIS and NISP
Size: 8800 x 8800 pixels
Although difficult to observe, IC 342, aka the ‘Hidden Galaxy’, has been imaged before. This image was taken in 2006 in visible light using the 64-megapixel Mosaic-1 digital imager on the Mayall 4-meter telescope at the Kitt Peak National Observatory in Arizona.
The image was released in Feb 2007 in Washington, DC, at the opening of “The Night: Why Dark Hours Are So Important,” a two-day symposium hosted at the Carnegie Institution.
