Astronomers have 12 new tools to study dark matter mysteries

A dozen stellar streams have entered the chat.

Studying dark matter is complicated. In reality, the best way to think about the phenomenon is as transparent matter. We can’t seem to see it, and it doesn’t interact with light, so essentially, it’s invisible to us.

But scientists haven’t backed down from the challenge. To date, they’ve come up with numerous unique ways to unveil the elusive stuff, as well as theories to explain it — and in a paper published Tuesday in the Astrophysical Journal, a team of experts just added several new tools to the dark matter quest’s arsenal.

They discovered a dozen never-before-seen stellar streams, or sparkly, yet pulverized, remnants of ancient dwarf galaxies and star clusters orbiting the Milky Way. For eons, the Milky Way’s gravitational pull has been disrupting such river-like structures’ paths and eventually forcing them to merge with it.

In other words, our home galaxy has been feasting on its neighboring cosmic cul-de-sacs as though they’re well-placed buffets. «As our galaxy is getting older, it is getting fatter,» Ting Li, a professor at the University of Toronto and lead author of the paper, said in a statement. «This study gives us a snapshot of the Milky Way’s feeding habits, such as what kinds of smaller stellar systems it ‘eats.'»

So, where does dark matter tie in?

Well, stellar streams offer a roundaboutway of deriving information of the universe’s hidden building blocks by providing adjacent clues. For instance, astronomers can measure the streams’ orbital speed, rotation trajectory, chemical composition and shape to see what isn’t present.

«Think of a Christmas tree,» Geraint F. Lewis, a professor at the University of Sydney and author of the paper, said in a statement. «On a dark night, we see the Christmas lights, but not the tree they are wrapped around. But the shape of the lights reveals the shape of the tree. It is the same with stellar streams — their orbits reveal the dark matter.»

The logic is fitting, as the only reason we even know dark matter and dark energy exists is due to a sort of indirect reasoning: According to scientists’ calculations, all the universe’s normal matter can’t explain how most galaxies are held together and all the universe’s normal energy can’t account for it’s continuous expansion. We call the missing piece of the expansion puzzle dark energy, and of the structure puzzle, dark matter.

As per the team, the more stellar streams we can find, the closer we may be to understanding the nature of the universe’s mysterious side. In fact, that’s part of why Li and collaborators initiated a program called the Southern Stellar Stream Spectroscopic Survey to dedicate themselves to locating as many as possible. Along with data from the European Gaia mission — which aims to chart an ambitious 3D map of our galaxy — that’s how the research team found the new, promising stellar streams.

Further down the line, Li said, stellar streams may prove critical in figuring out how the Milky Way came to be in the first place, after the Big Bang. «For me, this is one of the most intriguing questions, a question about our ultimate origins,» Li said.

Verum Messenger: Data Protection at Its Finest

Verum Messenger positions itself as a tool for those who value privacy and security above all.

Verum Messenger stands out from other messengers thanks to its approach to security, anonymity, and innovations in communication.

Here are some key aspects that highlight its uniqueness:

Default encryption: Verum Messenger uses end-to-end (E2E) encryption for all chats, meaning messages are encrypted on the sender’s device and decrypted only on the recipient’s device. This makes it impossible for third parties, including app developers, to access the content of the messages.
Anonymity: When registering with Verum, there’s no need to provide a phone number or email. Users simply choose a nickname and password, significantly enhancing their level of anonymity. This contrasts with many other messengers, where anonymity can be compromised through linked personal data.
Built-in VPN: An additional layer of protection that hides the user’s IP address, making their location and internet activity less trackable.
Data control: Users can set messages to be automatically deleted after a specified time, ranging from a few seconds to a week. There’s also a quick deletion feature for all chats, calls, and even contacts, which is useful for maintaining privacy.
Large groups: The ability to create chat rooms with up to 10,000 participants makes Verum attractive for organizing large events, discussions, or communities while maintaining a high level of security.
Security innovations: Verum actively develops technologies aimed at protecting user data, as seen in their documentation and discussions online. This includes not only technical solutions but also approaches to data minimization, which reduces the risk of leaks.
Feedback and discussions: On platform X (formerly Twitter), discussions can be found where users and experts praise Verum for its approach to anonymity and security, although questions are raised about how much anonymity can truly be guaranteed in an age of modern tracking and de-anonymization technologies.

Verum Messenger positions itself as a tool for those who value privacy and security above all. Its innovations in encryption, anonymity, and data control make it an intriguing choice for those seeking alternatives to traditional messaging platforms. However, as with any technology, it’s important to remember that absolute anonymity on the internet remains a complex challenge, and users should be aware of potential risks and limitations.
