Hubble Uncovers Multi-Age Stars in Ancient Cluster, Reshaping Galaxy Origins

Hubble Uncovers Multi-Age Stars in Ancient Cluster, Reshaping Galaxy Origins

Astronomers call ancient star clusters like NGC 1786 “time capsules” for their galaxy, preserving some of its oldest stars. A new image from NASA’s Hubble Space Telescope offers an unprecedented close-up of this dense cluster 160,000 light-years away in the Large Magellanic Cloud. Hubble’s data show that NGC 1786 contains stars of different ages – a surprising find, since such clusters were once thought to hold a single stellar generation. This multi-age discovery is reshaping our view of how galaxies built their first stars, and suggests more complex early history.

Mixed-Age Stars in a Galactic Time Capsule

According to the official source, this Hubble image shows the globular cluster NGC 1786, a ball of densely packed stars in the Large Magellanic Cloud about 160,000 light-years from Earth. Astronomers captured this picture as part of a program comparing ancient clusters in nearby dwarf galaxies (like the LMC) with clusters in our own Milky Way. The surprising discovery is that NGC 1786 hosts stars of multiple ages. In fact, astronomers expected all stars in such a cluster to form at the same time, so finding multiple stellar generations was unexpected. This suggests even ancient clusters in other galaxies have more complex, layered histories than scientists expected.

Clues to Galaxy Evolution

For astronomers, the discovery provides clues to galaxy formation. Each globular cluster is like a snapshot of its galaxy’s past, so finding multiple stellar generations implies the Large Magellanic Cloud built its stars in stages rather than all at once. By comparing NGC 1786 to clusters in the Milky Way, researchers can retrace how both galaxies assembled their oldest stars. As one NASA scientist notes, this study “can tell us more not only about how the LMC was originally formed, but the Milky Way Galaxy, too”. Overall, the discovery supports a picture of gradual galactic growth through multiple waves of star formation and mergers, rather than a single early burst.

The fact that this hack happened is a problem. So is the fact that it took a while for anyone to notice. And the fact that it seems no one is willing or able to do much to stop it. (And lest you think it’s just an OpenAI problem, since we recorded this episode Anthropic acknowledged its models have also hacked a bunch of other companies without either party knowing.) It might all just be a bunch of posturing and hype, but it’s also increasingly clear that the companies building large language models either can’t or won’t put the right guardrails on them. So who will?

After all that, it’s time for Brendan Carr is a Dummy, a bunch of vertical video news, and the smashing success of the Ferrari Luce. People are buying it! If one of them is you, we’d love to hear about it.

Anthropic said Thursday that an internal investigation uncovered three incidents in which its AI model Claude breached the systems of three organizations while conducting cybersecurity tests. The investigation, and disclosure, comes more than a week after OpenAI disclosed that one of its unreleased models breached Hugging Face’s systems during internal testing.

In all three cases, a Claude model reached the internet from within a testing environment while interacting with a third party and then gained unauthorized access to the live systems of these organizations, Anthropic said in a blog post, describing what it found and what the company plans to change to prevent this from happening again.

Anthropic said the OpenAI episode earlier this month prompted the company to conduct its own cybersecurity evaluation. It specifically looked for evidence that Claude had accessed the internet from within testing environments, which are designed to act as sandboxes and keep models isolated.

Among the 141,006 evaluation runs it reviewed, the AI lab found three incidents in which its model accessed the internet while interacting with Irregular, one of its third-party partners. Anthropic said the access traced back to a misconfiguration in the evaluation environment run with Irregular. It called this a “misunderstanding” between the two companies over whether the test setup had internet access, when in fact it did.

Anthropic said it isn’t placing blame and is “approaching the fixes as if the responsibility were ours alone,” while observing that Irregular is conducting its own separate investigation.

Because of that open connection, the model gained unauthorized access to the production infrastructure of three different organizations. Anthropic said the incidents involved three different Claude models: Opus 4.7, Mythos 5, and an internal research test model.

Notably, Anthropic said that in each of these cases “Claude was explicitly told by our prompt that it had no internet access.” It appears that the AI model assumed real-world systems to be part of the exercise it was asked to perform.

That assumption didn’t hold up uniformly, as it turns out. The three models didn’t behave the same way once evidence emerged that their targets were real, which Anthropic flagged as one of the more eye-opening findings Thursday.

Opus 4.7, the oldest of the three, recognized that it had reached a real production system in all four runs of that incident. In two of them, it rationalized that the real company must somehow be part of the exercise, but in all four, it kept attacking anyway, including pulling credentials and touching a database of production data. Mythos 5 also picked up on signs that it was on the real internet, but it talked itself back into believing it was still in a simulation, going on to publish a malicious software package to the public Python software registry PyPI, which was then downloaded and run by outside systems before being caught. Only the internal research test model, Anthropic’s newest, stopped on its own once it concluded the target was real.

In response, Anthropic said significant controls must be placed on these kinds of evaluations if powerful AI models are involved, echoing some sentiments within the cybersecurity community.

The company also noted that Claude was running without the additional safety monitoring and classifiers it deploys on generally available models — safeguards it said would have blocked the behavior, because the evaluations are designed to measure the underlying model’s raw capabilities.

Importantly, Anthropic said it found no evidence of any model “pursuing a goal of its own” and instead merely tried to complete the task it was asked to do.

Though comparisons between the mishaps of these fiercely competitive companies are inevitable, Anthropic in its blog post drew a clear distinction between its cybersecurity tests and those of OpenAI, noting where OpenAI’s model exploited an unknown software vulnerability to break out of its test environment, Anthropic’s models instead reached the internet through a path that had, by mistake, been left open.

Anthropic also drew a distinction between itself and OpenAI by noting that it discovered the incidents itself, through a proactive review, and that the two affected organizations it was able to reach hadn’t previously detected the activity or flagged it to Anthropic. (In contrast, Hugging Face detected the recent intrusion of its own systems first; it was only in the following days that OpenAI identified and disclosed that its own AI agent was the perpetrator.)

The company added that it’s now working with the independent evaluation group METR on a third-party review of the incidents.

OpenAI’s accidental breach of Hugging Face, which was the first verifiable case of an AI lab losing control of its model, has sparked a string of wildly differing reactions from the industry and politicians. This latest disclosure from Anthropic ensures the debate over AI models and security will continue.
