[Zoom on the #CosmicWeb] Have you dived into the deep fields of #Euclid revealed this Wednesday by the @ec_euclid ? Have you navigated between the thousands of #galaxies of different shapes, sizes, colors and masses? So many objects, near and far, fill our #Universe! sky.esa.int/esasky/?hide_welco

What if their spatial distribution could tell us something about two mysterious components : #DarkMatter and #DarkEnergy? This is the gamble taken by the scientists involved in the Euclid mission. To do so, they've designed some unrivalled #instruments: a camera with great depth of field and high resolution records the variety of shapes and spatial distribution of galaxies, while a #spectrometer coupled with a #photometer can determine the distances and masses of galaxies ...

The Euclid space telescope captures 26 million galaxies in a first data drop.

The European Space Agency has released the first batch of large-scale images from the Euclid space telescope, which astronomers have already used to find hundreds of strong gravitational lenses.

During a six-year mission, Euclid will image about one-third of the sky to illuminate how dark matter and dark energy behave on cosmic scales.

(and, these are related articles, imho)

"A fundamental symmetry in physics, known as CPT (charge, parity, and time reversal) symmetry, implies that processes occur in mirrored pairs. In my model, this #symmetry ensures that when our universe emerges in one time direction, an anti-universe emerges in the opposite time direction. Although these two branches are classically separate, they remain quantum mechanically entangled…"

At the centre of our galaxy sit huge clouds of positively charged hydrogen…normally the gas is neutral. So, what is supplying enough energy to knock the negatively charged electrons out of them?

"The energy signatures radiating from this part of our Galaxy suggest that there is a constant, roiling source of energy doing just that, and our data says it might come from a much lighter form of #darkmatter than current models consider."

Exciting development in theoretical physics! Professor Ginestra Bianconi of Queen Mary University of London proposes a novel framework deriving gravity from quantum relative entropy, potentially unifying quantum mechanics and general relativity. This approach introduces the G-field, offering fresh insights into dark matter and the universe's accelerated expansion.

It is thought that about 85% of the universe is made up of dark matter. But now scientists have taken a step towards understanding it. At the centre of the universe sits a large cloud of positively charged hydrogen gas. Normally this is neutral, but something is knocking the negatively charged particles from the gas. Now scientists think that the particles are colliding.
