A catalogue of 3,000 supernovae — the largest ever assembled — is challenging existing theories of dark energy
https://www.universetoday.com/articles/a-new-catalog-of-close-to-3000-supernova-challenges-theories-on-dark-energy
The most comprehensive catalogue of Type Ia supernovae ever assembled has produced new clues about dark energy, the mysterious force driving the universe's accelerating expansion — and some of those c

Astrum: *Scientists Say the Universe Could End in 30 Years*
"Scientists are predicting the end of the universe, and it could happen much sooner than we thought. For the first time, scientists have measured how dark energy is behaving right now, in the local universe, by measuring subtle shifts within our own solar system. How long do we actually have left? The answer might surprise you…"

The Beginnings of Man -Part 1
The nature of Man has evolved over millions of years, changed by environmental conditions, by the response of his instinctual nature and by the actions of his ego. Man’s inner characteristics are altogether different from the ancestral root which governs other species. Why then is he so different?https://tonyaholisticblog.com/2026/08/31/the-beginnings-of-man-part-1/

A DESI Milestone
Yesterday the Open Journal of Astrophysics published a paper by Porredon et al which will feature in the usual Saturday round-up. That paper, which is based on the First Data Release from the Dark Energy Spectroscopic Instrument (DESI) reminded me that I should mention that DESI recently reached an amazing milestone – it has now mapped the positions and redshifts of 47 million galaxies and quasars! There is a full press-release about this achievement here.
Here’s a little video showing how the survey works:

There are more videos and other graphics in the press release.
Here’s a nice picture showing a thin slice through the full survey that reveals the characteristic “cosmic web” of the large-scale structure of the Universe in all its glory:
This progress is great, but it really makes me feel old. Forty years ago, in 1986, I had just started my PhD. The state-of-the-art galaxy redshift survey slice then is shown in this plot, from de Lapparent et al 1986 (ApJLett 302, L1), one of the first papers I read as a research student (I got it in 1985 as a preprint), which contains just 1,100 galaxies:
It is worth mentioning that although DESI has now covered its original target area, it will continue until 2028. You can never have too many galaxy redshifts!

膨張宇宙理論を覆す大発見を目撃する──特集「THE WIRED WORLD IN 2026」

[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! https://sky.esa.int/esasky/?hide_welcome=true&hide_banner_info=true&hips=DES-DR2+ColorIRG&sci=false&layout=esasky&euclid_image=EDFS
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 ...

(Re-post)
Our new #EuclidConsortium website will be our main hub for communicating news & information about the #EuclidMission to the world.
Do you want a primer on the mission? Go to our Mission tab and read about the telescope, instruments, surveys, and simulations.

In July we will launch the #Euclid #spacecraft, but this week we already re-launched our #EuclidConsortium website:
It has been completely overhauled and now provides up-to-date primers on science, mission information, a Blog, press material, and a growing set of images. Visit us!
-
Happy to announce that the website of the #EuclidConsortium (@ec_euclid) has been re-launched with a complete structural, technical, and - most important - content overhaul: https://euclid-ec.org
For everything #EuclidMission #Euclid please have a look, there'll be blog-posts, infos or scientists and press, growing image galleries and so forth.

20 days exactly until opening of #Euclid's contractual launch window. 8 days until @ec_euclid annual meeting in Copenhagen. Less than half a year until we'll have science data.
And 1 day until we relaunch the
