This Scrollable Map of the Universe Reminds Us How Tiny We Really Are

It’s a bit unsettling to scroll through this website scientists made to detail the observable universe. I highly recommend doing it.

When you open up Johns Hopkins University Professor Brice Ménard’s «map of the observable universe,» you’re met with a geometric diagram overflowing with thousands of rainbow freckles, each neatly organized by color. At the bottom of this diagram lies an unnerving phrase.

«You are here.»

One negligible, barely visible dot on this graph represents our entire Milky Way galaxy — a realm with billions of stars besides our own sun, and one we occupy such a small percentage of I don’t even want to attempt writing it out.

With a single pixel, Ménard stunningly puts into perspective the cosmic brevity of everything we’ve ever truly known as human beings.

«This map, representing galaxies just as little dots, allows the viewer to basically understand different scales at the same time,» Ménard said in an overview of the interactive mechanism. «Seeing the vastness of the universe — it’s quite inspiring.»

Scrolling around the 200,000 galaxies in the map — placed in accurate, relative positions to one another — is calming because it reframes how inconsequential the footprint we place in the universe is. It’s disturbing for precisely the same reason.

It draws a distinct parallel with Carl Sagan’s famous quote about Voyager 1’s breathtaking image of Earth from 1990, «Pale Blue Dot.»

«Look again at that dot. That’s here. That’s home. That’s us,» Sagan said. «On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam.»

Though if you’re blown away by the deceptively concise magnitude of Ménard’s map, consider how it doesn’t even account for every galaxy in the universe. In reality, NASA estimates there are something like a hundred billion galaxies unfolding eternities beyond our own.

We’d need an unfathomable level of observable universe cartography to encapsulate the full breadth of the cosmos.

Slice of our universe

Along with a cadre of scientists, Ménard used data mined over two decades by what’s known as the Sloan Digital Sky Survey.

«Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries,» Ménard said. «But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like.»

Once you click «explore the map» under the Milky Way galaxy label, you arrive at a screen prompting you to «scroll up to travel through the universe.» That such a sentence even exists underscores just how far technology has come.

«From this speck at the bottom,» Ménard said, «we are able to map out galaxies across the entire universe, and that says something about the power of science.»

Even more impressive is how, as you follow the prompt, a ticker at the bottom left of the screen shows you how many billions of years back in time you’ve scrolled. Meanwhile, the dots go from gradients of pale blues to yellows to oranges to reds, ultimately retreating to a cool midnight hue.

«Each dot is a galaxy shown with its apparent color,» the page reads. «Spiral galaxies are faint and blue. Our galaxy, the Milky Way, is a blue spiral.»

Elliptical galaxies are shown as yellowish and brighter, while reddened speckles indicate realms that have grown distant enough for the light they emanate to stretch and appear to us on Earth as crimson blurs.

Further back 9 billion years, the map exhibits vivid blue spots to represent quasars rather than galaxies. These are extreme jets of light spewing out from the guts of black holes sitting at the center of certain galaxies.

Basically, it’s really hard to see galaxies from this era of cosmic history, reddened to the point of near-invisibility, but quasars are bright enough to act like flashlights. Their brilliance shines across the universe, revealing scenes otherwise shielded by darkness and softened with distance.

But beyond even those quasars lies a splotch of blackness — evocative of the mysteries lurking beyond the red end of the electromagnetic spectrum. Infrared waters.

«We encounter an epoch during which the universe is filled with hydrogen gas that prevents the propagation of visible light we could observe today. This epoch is called the «dark ages,'» the page reads.

NASA’s magnificent James Webb Space Telescope is such a big deal because it’s built to find secrets hidden in this region invisible to human eyes. Constructed with an army of high-tech infrared sensors, it’s working on detecting galaxies from near the beginning of time stuck in a limbo we cannot see with our minds or machines.

With each Webb discovery, hopefully maps like this one will become populated where their empty spaces currently sit.

And at the very, very top of the page, a marbled photo of the edge of the observable universe. The first flash of light emitted post-Big Bang, nearly 14 billion years ago. The Cosmic Microwave Background.

«We cannot see anything beyond this point,» the map concludes after you scroll back to the beginning of existence. «The light travel time to us is greater than the age of the universe.»

Southwest Airlines Says You Can’t Use Portable Chargers Inside Your Bags

There’s a new airline safety rule for everyone’s favorite travel tech because of the risk of fire.

Southwest Airlines is implementing a new safety policy, effective May 28, requiring passengers to keep portable phone chargers and power banks visible during flights when you’re charging a device. The airline will prohibit the use of these devices while they’re stored in carry-on bags or overhead bins, aiming to mitigate the risk of lithium-ion battery fires.

This policy change comes in response to a series of incidents involving overheating lithium-ion batteries. According to the Federal Aviation Administration, there have been 22 battery-related incidents on flights in 2025 alone, following a record 89 such events in 2024. Notably, a fire aboard an Air Busan flight in South Korea in January — suspected to have been caused by a power bank with deteriorated insulation — led to the evacuation of 176 people, including passengers and crew.

While the FAA and the Transportation Security Administration currently allow lithium-powered devices, like e-cigarettes and power banks, in carry-on luggage but prohibit them in checked bags, they do not mandate that portable chargers be kept in plain sight. Southwest’s new policy goes a step further, aligning with practices already adopted by some Asia-based carriers, including Singapore Airlines, AirAsia and all South Korean airlines, according to Reuters.

This move by Southwest Airlines reflects a growing concern in the aviation industry regarding the safe transport and use of lithium-ion batteries on aircraft. Passengers are encouraged to stay informed about airline policies and to handle electronic devices with care to ensure a safe travel experience.

«Southwest will introduce a first-in-industry safety policy on May 28 requiring customers to keep portable charging devices visible while in use during flight,» Southwest Airlines confirmed in a statement to CNET via email. «Using portable charging devices while stored in a bag or overhead bin will no longer be permitted. Nothing is more important to Southwest than the safety of its customers and employees.»

Sega’s Re-Released Games for Switch 2 Include Yakuza 0 and Puyo Puyo Tetris 2S

The first of Sega’s third-party games to hit the console are re-releases from consoles past.

As the Nintendo Switch 2 prepares to launch, its list of third-party games grows, including a trio of Sega and Atlus games that include classics and deep cuts. I got to play all three ahead of the Switch 2 release on June 5.

The three games — Yakuza 0: Director’s Cut, Puyo Puyo Tetris 2S and RAIDOU Remastered — are odd bedfellows that represent distinct eras and genres among Sega’s oeuvre. All three play well on the Switch 2, which is unsurprising given the console’s rumored PS4-equivalent performance but still reassuring given the original Switch’s limited capability.

Yakuza 0 is the marquee title of the trio for its role in the series — a prequel to the original Yakuza and de facto entry point for new players that details the origins of fan favorites Kazuma Kiryu and Daigo Dojima. In addition to the story, Yakuza 0: Director’s Cut includes a new mode, Red Light Raid, that lets you pick a character from a roster of Yakuza heroes and nobodies to brawl with successively harder rounds of enemy groups.

While dated compared with the sharp combat and graphics of the latest in the series, February’s Pirate Yakuza in Hawaii, Yakuza 0 is still a fantastic game and great to have on the new console. I only played it in docked mode, so I can’t say how the game plays in handheld with a 1080p and 120 frames per second display graphics cap.

Raidou Remastered: The Mystery of the Soulless Army is a deeper cut, the third game in the Devil Summoner series within the Megami Tensei franchise, which was originally released for the PS2 in 2006. Though the game has been refreshed for modern consoles (the game will also be out on PS5, Xbox Series X/S, PC and last-gen systems), it preserves the charm of the era’s games — one where very little is explained and players have to figure it out for themselves. (I had to have a certain solution to a puzzle spelled out for me.)

Starring the eponymous Raidou as a detective assisted by demons he captures and can use to investigate denizens of his town or summon for battle in real-time combat, the game is a little slower and less dense than today’s graphically-intense titles.

Puyo Puyo Tetris 2S is the opposite — a contemporary puzzle game first released in 2020 for current and last-gen consoles, the re-release preserves the bright colors and frantic gameplay with a few new multiplayer modes. In our preview, Sega paired up gamers for 2-vs-2 puzzler matches where we tried to stay out of each other’s way while clearing lines. For Switch 2, players can switch from Joy-Con mode to Mouse mode, which is precise enough but adds to the frenetic tension.
