Astronomers Spot a Ghostly Light Glowing Throughout the Solar System

Scientists used NASA’s Hubble Space Telescope to identify the presence of an unexplained glow amid the blackness of space.

The deep darkness of space might not actually be so dark in our solar system.

Astronomers analyzed over 200,000 images from NASA’s Hubble Space Telescope, making tens of thousands of measurements to try to locate a residual background glow in the night sky. The project is called SKYSURF, which is based at Arizona State University and involves researchers there and around the world.

The team harvested the data from the images and then subtracted the glow from planets, stars, galaxies and even ethereal zodiacal light, which is light reflecting off dust within our solar system.

After accounting for all this there was still a tiny bit of leftover glow or «ghost light,» which the researchers describe as equivalent to the glow of 10 fireflies spread across the entire night sky.

«We think it is a local phenomenon that is not from far outside the solar system,» ASU researcher Tim Carleton explained in a statement Thursday. «It may be a new element to the contents of the solar system that has been hypothesized but not quantitatively measured until now.»

A leading explanation is that the glow comes from a previously unaccounted for sphere of dust left behind by countless comets traveling through the solar system from all directions.

The discovery is documented in a handful of studies. Two have been published in the Astronomical Journal and another in Astrophysical Journal Letters.

One of the studies was led by Rogier Windhorst from ASU, who points out that over 95 percent of the photons in Hubble’s images come from distances on our side of the universe, less than 3 billion light-years from Earth.

«Since Hubble’s very early days, most Hubble users have discarded these sky-photons, as they are interested in the faint discrete objects in Hubble’s images, such as stars and galaxies,» Windhorst said. «But these sky-photons contain important information which can be extracted thanks to Hubble’s unique ability to measure faint brightness levels to high precision over its three decades of lifetime.»

And within that information, Windhorst and others may have just located a completely new piece of ethereal architectureunderlying our entire solar system. If you consider a faint but ubiquitous layer of dust to be architecture, that is.

Microsoft Is Eliminating Passwords in August: Here’s What You Need to Do to Prepare

Microsoft Authenticator has already stopped autofilling passwords, but the biggest change comes next month.

In June, Microsoft Authenticator stopped letting users create new passwords. In July, it turned off the autofill password function. And in August, the login app will stop supporting passwords entirely, moving to more secure passkeys, such as a PIN, fingerprint or facial recognition.

Attila Tomaschek, CNET’s software senior writer and digital security expert, says that passkeys are a safer alternative to the risky password habits practiced by 49% of US adults, according to a recent survey by CNET.

«Passwords can be cracked, whereas passkeys need both the public and the locally stored private key to authenticate users, which can help mitigate risks like falling victim to phishing and brute-force or credential-stuffing attacks,» Tomaschek said.

Using the same password for several accounts or adding personal hints can be a convenient way to remember your login. But that puts you at a big risk for scammers, identity theft and fraud. Here’s more on Microsoft’s plan for eliminating passwords and how to make the switch to passkeys before August.

When will Microsoft Authenticator stop supporting passwords?

Microsoft Authenticator houses your passwords and lets you sign into all your Microsoft accounts using a PIN, facial recognition like Windows Hello, or other biometric data like a fingerprint. Authenticator can be used in other ways, such as verifying you’re logging in if you forgot your password, or using two-factor authentication as an extra layer of security for your accounts. In June, the company stopped letting users add passwords to Authenticator, but here’s a timeline of other changes you can expect from Microsoft.

July 2025: You won’t be able to use the autofill password function.
August 2025: You’ll no longer be able to use saved passwords.

If you still want to use passwords instead of passkeys, you can store them in Microsoft Edge. However, CNET experts recommend adopting passkeys during this transition. «Passkeys use public key cryptography to authenticate users, rather than relying on users themselves creating their own (often weak or reused) passwords to access their online accounts,» Tomaschek said.

Why are passkeys a better alternative to passwords?

So what exactly is a passkey? It’s a credential created by the Fast Identity Online Alliance that uses biometric data or a PIN to verify your identity and access your account. Think about using your fingerprint or Face ID to log into your account. That’s generally safer than using a password that is easy to guess or susceptible to a phishing attack.

Passkeys aren’t stored on servers like passwords. Instead, they’re stored only on your personal device. More conveniently, this takes the guesswork out of remembering your passwords and the need for a password manager.

How to set up a passkey in Microsoft Authenticator

Microsoft said in a May 1 blog post that it will automatically detect the best passkey to set up and make that your default sign-in option. «If you have a password and ‘one-time code’ set up on your account, we’ll prompt you to sign in with your one-time code instead of your password. After you’re signed in, you’ll be prompted to enroll a passkey. Then the next time you sign in, you’ll be prompted to sign in with your passkey,» according to the blog post.

To set up a new passkey, open your Authenticator app on your phone. Tap on your account and select «Set up a passkey.» You’ll be prompted to log in with your existing credentials. After you’re logged in, you can set up the passkey.
