Across its entire fields, Euclid revealed today 15 000 strong lensing candidates.

Together, they make up the largest-ever catalogue of strong cosmic lenses, bigger than all previous catalogues combined.

Today’s dataset (below) only covers about 14% of the total sky area Euclid will survey.

The full Data Release 1, to come in mid-2027, will build on today’s release and add more crucial parts to the cosmic puzzle, including observations of weak lensing, among others.

Stay tuned!

To think – 900 million galaxies. Imagine if they each bought just one of my books.

Here is a zoom through some of @ec-euclid.bsky.social 's strong gravitational lenses - also a tribute to the late Yannick Mellier, a pioneer of gravitational lensing, visionary scientist, driving force behind the Euclid mission (made by ELSA member @stephenserjeant.bsky.social) 🔭

I was intrigued by uncover_26185, in my JWST news page. It happens to be in ABELL2744, a busy spot. Some lensing is visible.

Van Gogh painted 'Starry Night' of stars in the Hyades cluster, Venus, & a waning crescent moon. Stars in the Hyades were also those whose apparent positions were shifted by gravitational lensing during 29 May 1919 total solar eclipse – providing 1st proof for Einstein's Theory of General Relativity

Y’ALL THIS IS SO COOL!!! The Euclid space telescope had their first data release today and amongst the 900 million galaxies they observed they found a TON of these strong gravitational lens systems-over 15,000 candidates! Here are a few:

I'm not so sure that gravitational lensing will give answers to dark matter & energy as suggested but this data from the EU Euclid mission is terrific

Strong lensing allows scientists to ‘weigh’ individual galaxies, including their invisible dark matter, and explore how the Universe is expanding.

With spectroscopy, they can determine which materials are present in a galaxy, and also measure its distance.

Abell 2744 is a massive foreground cluster, so its gravity can magnify and stretch background galaxies into arcs. That lensing can reveal very distant objects, though it also distorts their apparent shapes.

They used telescopes but it could be possible with a bright enough star in the right place during a total solar eclipse to see a gravitational lensing event.

Lots of ifs but not impossible
