Along those lines, there was an article in Scientific American a few months back about the "voids" in the universe (the dark spots in the above map) where there is almost nothing at all (except dark energy, which is mostly constant) for truly vast distances. They are understudied but may be extremely important to understanding the evolution of the universe.

Do you think you could find it?

How Analyzing Cosmic Nothing Might Explain Everything
Huge empty areas of the universe called voids could help solve the greatest mysteries in the cosmos

Computational astrophysicist Alice Pisani put on a virtual-reality headset and stared out into the void—or rather a void, one of many large, empty spaces that pepper the cosmos. “It was absolutely amazing,” Pisani recalls. At first, hovering in the air in front of her was a jumble of shining dots, each representing a galaxy. When Pisani walked into the jumble, she found herself inside a large swath of nothing with a shell of galaxies surrounding it. The image wasn't just a guess at what a cosmic void might look like; it was Pisani's own data made manifest. “I was completely surprised,” she says. “It was just so cool.”

The visualization, made in 2022, was a special project by Bonny Yue Wang, then a computer science undergraduate at the Cooper Union for the Advancement of Science and Art in New York City. Pisani teaches a course there in cosmology—the structure and evolution of the universe. Wang had been aiming to use Pisani's data on voids, which can stretch from tens to hundreds of millions of light-years across, to create an augmented-reality view of these surprising features of the cosmos.

Study reveals when the first warm-blooded dinosaurs roamed Earth

Were dinosaurs warm-blooded like birds and mammals or cold-blooded like reptiles? It’s one of paleontology’s oldest questions, and gleaning the answer matters because it illuminates how the prehistoric creatures may have lived and behaved.

Challenging the prevailing idea that they were all slow, lumbering lizards that basked in the sun to regulate their body temperature, research over the past three decades has revealed that some dinosaurs were likely birdlike, with feathers and perhaps the ability to generate their own body heat.

However, it’s hard to find evidence that unquestionably shows what dinosaur metabolisms were like. Clues from dinosaur eggshells and bones have suggested that some dinosaurs were warm-blooded and others were not.

A new study published in the journal Current Biology on Wednesday suggested that three main dinosaur groups adapted differently to changes in temperature, with the ability to regulate body temperature evolving in the early Jurassic Period about 180 million years ago.

The Xuntian space telescope hasn't even been launched into orbit yet, and already the Chinese are claiming bragging rights over it:

Chinese astronomers say their new space telescope will outdo Hubble

Most unfortunate:

China’s giant Xuntian space telescope faces further delay until late 2026

Euclid is swiftly coming into its own alongside the James Webb space telescope:

Euclid space telescope captures dazzling new images of the cosmos: "Never seen anything like it"


Messier 78, a vibrant star nursery enveloped in interstellar dust, ESA

A mind-boggling number of shining galaxies, a purple and orange star nursery and a spiral galaxy similar to our Milky Way: new images were revealed from Europe's Euclid space telescope on Thursday.

It is the second set of images released by the European Space Agency since Euclid launched last year on the first-ever mission to investigate the mysteries of dark matter and dark energy.

"The never-before-seen images demonstrate Euclid's ability to unravel the secrets of the cosmos and enable scientists to hunt for rogue planets, use lensed galaxies to study mysterious matter, and explore the evolution of the universe," the European Space Agency said in a statement.

Scientific data from Euclid was also published for the first time in the six-year mission, which aims to use its wide view to chart two billion galaxies across a third of the sky.
