This Galaxy Is 99% Dark Matter—and Basically Invisible

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass. Because it’s so abundant, astronomers believe it should explain many unsolved mysteries surrounding the cosmos, including an extraordinary dim galaxy “hiding” in plain sight.

Last summer, astronomers vetted candidates for so-called dark galaxies, or a rare class of galaxies with remarkably low surface brightness. The paper on the findings, published in The Astrophysical Journal Letters, surmised that so-called “dark galaxies” should have “some of the most extreme properties among all known galaxies.”

And today, NASA shared high-resolution images of one such galaxy, CDG-2. If the astronomers’ hypothesis is correct, CDG-2 would be among the most heavily dark-matter-filled galaxies ever identified.

“Seeing” the invisible

Again, dark matter doesn’t interact with light. However, astronomers infer its presence from dark matter’s gravitational influence on surrounding objects. Often, this refers to unseen mass that seems to be driving galaxies, planets, stars, and supernovas—you name it—to appear a certain way.

Simply put, if dark matter didn’t exist, many of the models scientists use to understand the cosmos would break down. Although scientists have yet to directly detect dark matter, dissenters have also yet to find an alternative that explains things better. So the consensus, at least for now, is that dark matter exists.

Hints of an invisible galaxy

CDG-2 lies within the Perseus galaxy cluster, a section of the universe filled with globular clusters, or tightly bound units filled with millions of stars. Accordingly, this neighborhood is known for its particularly rich population of densely packed stars.

Then, Hubble noticed a close collection of four globular clusters among the bunch. When Hubble, ESA’s Euclid, and the Subaru Telescope in Hawaii collectively took a closer look, astronomers noticed a faint glow circling the area—leading them to wonder if the whole thing was actually just one galaxy.

The researchers behind the study conducted a statistical analysis of the galaxy, finding that the four clusters likely are part of a single galaxy—and a dark one at that.

“This is the first galaxy detected solely through its globular cluster population,” David Li, the study’s lead author and an astronomer at the University of Toronto, said in a NASA release.

A crowded neighborhood

According to the researchers, CDG-2 has a luminosity equivalent to roughly 6 million Sun-like stars, with the globular clusters contributing around 16% of that total. In terms of mass, however, 99% of the galaxy’s mass appears to be dark matter.

The “normal” matter in CDG-2—primarily hydrogen gas for star formation—was likely stripped away by the dense population of galaxies inside the Perseus cluster, the scientists said. But even if CDG-2 isn’t necessarily a dark galaxy, it’s still an odd one, the researchers said, and would be an ideal candidate to study and test theories on clustered star formation and its potential implications, according to the paper.

Either way, it looks like astronomers have no shortage of things they’re counting on dark matter to prove.

reports, Vivo has started preparations for launching its S series phones back in India with the release of the Vivo S2 smartphone. While Vivo hasn’t officially confirmed a release date, some reports indicate the phone could launch on August 6th, with sales expected to begin on August 11. This would mark the revival of the S series of phones in India following the debut of the Vivo S1 phone back in 2019. Reports have also given an early look at its design while revealing details about its expected specifications, color options, and launch plans.

Expected Specifications and Camera Features

Leaks suggest the Vivo S2 will feature an OLED display with a refresh rate of up to 120Hz. The phone may use the MediaTek Dimensity 7360 chipset, built on a 4nm process. Reports also suggest the phone will come in 8GB + 128GB and 8GB + 256GB variants. On the camera front, the Vivo S2 is tipped to include a 50MP Sony main sensor. Some information also suggests that the phone would be capable of recording videos in 4K quality through both front and rear cameras.

According to some recent leaks, the Vivo S2 would come with a sleek design. It would have a 3D curved display with narrow borders and a punch-hole selfie camera at the center of the device. On the back side, there would be a camera module in the shape of a pill with two big rings and an LED flash. Unlike many smartphones, the camera module matches the rear panel color for a more seamless finish. Vivo could offer the phone in Sapphire Blue, Regal Bronze, and Silk White. Its design closely resembles the Vivo X300 FE. Vivo has not shared any battery details yet. However, one report suggests the Vivo S2 may pack a 7,000mAh battery. This information is still based on leaks and awaits official confirmation.

Expected Price of Vivo S2

The Vivo S2 could target India’s premium mid-range smartphone market. It might cost anywhere between ₹40,000 and ₹50,000, though Vivo has not yet officially announced its pricing. Some leaks also reveal internal listing prices, but they may differ from the final retail price. On launch, the Vivo S2 will challenge the OnePlus Nord 6 and the Motorola Edge 70 Pro smartphones. It will also take on the Realme 16 Pro series and Vivo V70 FE.

Before Denis Villeneuve came aboard as the next James Bond movie director, another intriguing project was sitting in his potential “to-do” pile: an adaptation of Nuclear War: A Scenario, Annie Jacobsen‘s 2024 book that uses extensive interviews and research to examine, minute by minute, what would happen if nuclear war broke out. Her latest book sounds very much in that same vein; it’s titled Biological War: A Scenario, and though it’s just been released today, it’s already been scooped up for adaptation.

Variety reports that Patrick Macmanus (the creator of Peacock’s Devil in Disguise: John Wayne Gacy) secured the rights to a television adaptation for his production company; he and Jacobsen will co-create and serve as executive producers on Biological War.

The book takes a close look at the seconds, minutes, hours, and days after the release of a microscopic agent that could bring down civilization if it’s allowed to spread across the globe. And it’s a weapon, not unlike The Stand‘s Captain Trips, so presumably the show will include a heavy government-military aspect to things as well.

“What begins with a routine day leads to the end of the world six days later,” Macmamus told Variety. “But it isn’t ultimately a nihilistic show. Yes. There’s the dark excitement and exploration of the apocalypse. But there’s a parallel story of the instinct to protect and rebuild. A celebration of community and family. The wish-fulfillment of starting the human experiment over again in the hopes of getting it right this time around.”

The Variety piece mentions the potential Villeneuve adaptation of Nuclear War, so maybe we’ll get to see that on screens eventually too. So far, there’s no streamer or network locked in for Biological War, but the trade writes “the television adaptation will be taken out to buyers in the upcoming weeks.”
