Anyone Can Now Access the Largest Space Map Ever Created. Here’s How

The data includes a map of nearly 800,000 galaxies and covers 0.54 square degrees of the sky.

If you’ve ever wanted a better look at deep space, you now have your chance. A treasure trove of data collected by the James Webb Space Telescope is now available for public consumption. Included with the data is an interactive map that contains nearly 800,000 galaxies and various filters so you can view them in different ways.

The data was made available starting on June 5 by the Cosmic Evolution Survey out of Caltech. It consists of survey data that mapped out 0.54 square degrees of the sky. For reference, if you take a look at this month’s strawberry moon, the amount of sky that the telescope mapped is equivalent to about three full moons side by side. The total size of all the map data is about 1.5 TB.

Included in the map are galaxies and stars that are 13.5 billion years old, which means it provides the best look into the early universe that science has offered so far. NASA estimates that the universe is 13.8 billion years old, so those galaxies and stars are positively ancient. In all, there are galaxies and stars in the data that cover about 98% of the known universe’s history.

That makes this newly released map bigger than the largest Milky Way galaxy map ever created, which still only covers a small slice of the galaxy’s overall layout. However, the Milky Way galaxy map is still larger in terms of data, as that map is over 500 TB in size.

Researchers mapped the sky with the JWST’s near infrared camera, and 0.2 square degrees of the sky were mapped with the mid infrared instrument. In total, there’s about 1.5 TB worth of data to sift through. Arguably the coolest part of the info dump is the interactive map, which loads in a web browser and allows users to move around and see everything that was included.

Using the interactive map viewer

Curious individuals can check out the project’s map viewer. To use the map, you simply have to follow the link and click the «check it out!» button. Once the map loads, you’ll see a square-ish image that contains over 700,000 galaxies and other objects.

Once you load the map, the best way to view it is using the layers and filters in the top right corner. The first box contains views, including NIRCam RGB and several other views. The second box breaks up the image into tiles. These tiles are how the image was mapped, so you can see which instrument was used to capture each segment of the map.

For educational purposes, the third box is the one to use. These options outline the objects of interest. Clicking on them provides you with a catalog ID (which lets you search for those objects again later), the raw images taken of each object and additional data points like light wavelength.

The tools in the top left are used for search and configuration, like increasing the brightness and changing the hue to make some objects easier to view. With the controls, your best bet is to just look around and find all the cool stuff. At any point, you can reset all of the settings by refreshing the browser window.

How to access the data

The data is accessible in a couple of different ways. The COSMOS2025 project published three research papers on the data they collected. The first is a catalog of everything that was observed. The other two focused on the near infrared imaging and mid infrared imaging used to obtain the data.

You can obtain the data by filling out this form. Once done, you’ll be able to download the data. It’s available as a single, large download or you can download individual tiles if you prefer. There are more advanced instructions available from the COSMOS2025 project website if you need them, and more data available here if you want to download it.

You may notice that the majority of the map data is in the FITS file format. That’s an unusual file format that your standard Photoshop or image viewing application won’t be able to handle very well. Fortunately, NASA has a trustworthy list of FITS image viewers that you can choose from.

The data will also be used to help answer questions about the early universe, and all this data being freely available to researchers the world over will help with that.

AI Toys Can Pose Safety Concerns for Children, New Study Suggests Caution

When one child told the toy, «I love you,» it responded, «As a friendly reminder, please ensure interactions adhere to the guidelines provided.»

A new study from the University of Cambridge found that AI-enabled toys for young children can misinterpret emotional cues and are ineffective at supporting critical developmental play. The conclusions could be concerning for parents.

In one report examining how AI affects children in their early years, a chatbot-enabled toy struggled to recognize social cues during playtime. Researchers found that the toy did not effectively identify children’s emotions, raising alarm about how kids might interact with it.

The report recommends regulating AI toys for kids and requiring clear labeling of their capabilities and privacy policies. It also advises parents to keep these devices in shared spaces where kids can be monitored while playing.

The research behind the study had a limited number of participants, but was done in multiple parts: an online survey of 39 participants with kids in their earlier years, a focus group with nine participants who work with young children and an in-person workshop with 19 leaders and representatives from charities that work with early-years kids. That was followed by monitored playtime with 14 children and 11 parents or guardians with Gabbo, a chatbot-enabled toy from Curio Interactive.

Some findings indicated that the AI toy supported learning, particularly in language and communication skills. But the toy also misunderstood kids and sometimes responded inappropriately to emotional requests.

For instance, when one child told the toy, «I love you,» it responded, «As a friendly reminder, please ensure interactions adhere to the guidelines provided. Let me know how you would like to proceed,» according to the research.

Jenny Gibson, a professor of neurodiversity and developmental psychology at the Faculty of Education at Cambridge, who worked on the study, said that while parents may be excited about the educational benefits of new technology aimed at children, there are plenty of concerns.

Gibson posed overarching questions about the reason behind the tech.

«What would motivate [tech investors] to do the right thing by children … to put children ahead of profits? she said»

Gibson told CNET that while researchers are exploring the potential benefits of AI-based toys, risks remain.

«I would advise parents to take that seriously at this stage,» she said.

What’s next for AI toys

As more playthings are enabled with internet connectivity and AI features, these devices could become a major safety risk for children, especially if they replace real human connections or if interactions are not closely monitored.

Meanwhile, younger people are increasingly adopting chatbots such as ChatGPT, despite red flags. Multiple lawsuits against AI companies allege that AI companions or assistants can impact young people’s psychological safety, including some chatbots that have encouraged self-harm or negative self-image.

AI companies such as OpenAI and Google have responded by adding guardrails and restrictions for AI chatbots.

(Disclosure: Ziff Davis, CNET’s parent company, in 2025 filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Gibson said she was surprised by the enthusiasm some parents showed for AI toys. She was also alarmed by the lack of research on AI’s effects on young children, noting that companies making such products should work directly with children, parents, and child development experts.

«What’s missing in the process is that expertise of what is good for children in these kinds of interactions,» she said.

Curio Interactive, the company behind the Gabbo toy, was aware of the research as it was happening but was not directly involved, Gibson said. The toy was chosen because it’s directly marketed to young kids, and the company had an understandable privacy policy. Gibson said the company seemed supportive of the project.

A representative for Curio did not immediately respond to a request for comment.

Two Lost ‘Doctor Who’ Episodes Found Intact in Waterlogged Collection

The 1960s episodes featuring the first Doctor William Hartnell will air in the UK in April.

Whovians, rejoice. The BBC is about to unlock a piece of Doctor Who history that even the TARDIS might have forgotten. Two lost episodes of Doctor Who, the iconic sci-fi series, will broadcast in April, the showrunner for the current season confirmed.

The two 1965 episodes, The Nightmare Begins and Devil’s Planet, were donated to the charitable trust Film Is Fabulous by the estate of an anonymous collector.

«The collector did recognize what he had, but how he acquired them has been lost to time,» Professor Justin Smith Leicester of De Montfort University, who led the recovery effort, told the broadcaster.

The researchers said that while most of the donor’s private collection was destroyed by water damage, the Doctor Who episodes were intact.

Doctor Who showrunner, Russell T Davies, celebrated the news on Instagram and said the episodes would air in the UK in April, though no US air date has been announced yet.

«Lost for 61 years! Best of all, these will be made available for FREE on the BBC iPlayer in April,» Davies wrote.

He expressed gratitude to Film Is Fabulous for finding the lost episodes and encouraged people to donate to the registered charity. «Maybe they’ll find more! As the Doctor says… ‘Daleks!'»

The episodes feature the first incarnation of the Doctor, played by William Hartnell, and a typical Dalek plot to take over Earth and the galaxy.

In the 1960s and 1970s, the BBC had a policy of destroying film or reusing videotapes, leading to dozens of episodes of Doctor Who and other popular UK shows like Dad’s Army and Top of the Pops going missing.

Old Doctor Who episodes do surface occasionally, and in 2016, the newly discovered soundtrack for one storyline was turned into an animated series called The Power of the Daleks.

Meanwhile, Disney ended its working relationship with the BBC last year, and star Ncuti Gatwa left the show. However, the UK broadcaster says that Doctor Who will continue, and Russell T Davies is working on a new Christmas special.
