I swapped my favorite Linux desktop for System76's COSMIC alpha - and I have zero regrets

Jack Wallen / Elyse Betters Picaro / ZDNET Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways System76's COSMIC desktop will soon be in beta. Even as an alpha release, COSMIC is impressive. COSMIC is as fast as any Linux desktop I've experienced. Alpha releases aren't to be used for any reason other than testing. Right? That's the common opinion, and yet here I am, working on System76's COSMIC desktop as if it's in stable status. It's not... and it shows. Yes, I

A Super-Energetic Neutrino That Reached Earth in 2023 Has Been Confirmed to Be Real. But Where Did It Come From?

In February 2023, a cosmic particle detector housed deep in the Mediterranean Sea recorded the arrival of a neutrino with approximately 20 to 30 times more energy than any other neutrino documented previously. Labelled KM3-230213A, the particle had a calculated energy of 220 petaelectronvolts (PeV), far greater than the 10 PeV of the previously most energetic neutrino. The finding generated a lot of excitement among physicists, but raised also many questions. Neutrinos are the most abundant par

The Mysterious Origins of the Most Energetic Neutrino Ever Detected

Astronomers in Awe of Terrifying "Eye of Sauron" That's Pointed Straight at Earth

A bright galactic nucleus with a supermassive black hole that spews out cosmic radiation is pointing straight at us. Thankfully, the object, unimaginatively dubbed "PKS 1424+240," is located roughly 7.4 billion light-years away and likely won't pose much of a danger. But that hasn't stopped a group of excited astronomers from renaming it: the "Eye of Sauron," the symbol adopted by the Dark Lord in JRR Tolkien's epic "Lord of the Rings" trilogy. A new image of the object was recently unveiled,

Heaviest Black Hole Ever Found Pushes Limit of What’s Cosmologically Possible

The largest black hole ever detected is 36 billion times the mass of our Sun. It exists near the upper limit predicted by our cosmological models, leaving astronomers with burning questions surrounding the relationship between black holes and their galaxy hosts. In a paper published August 7 in Monthly Notices of the Royal Astronomical Society, researchers announced the discovery of a black hole inside a supermassive galaxy 5 billion light-years from Earth, dubbed the Cosmic Horseshoe. The newl

Cosmic Dawn: The Untold Story of the James Webb Space Telescope

Go behind the scenes with the dedicated NASA team and its partners to uncover the untold story of the James Webb Space Telescope. “Cosmic Dawn” unveils the immense challenges, groundbreaking innovations, and extraordinary efforts behind humanity’s most powerful eye on our universe, from its complex development to its nail-biting deployment a million miles away.

Scientists Working to Decode Signal From Earliest Years of Universe

As mysterious as the Big Bang that gave birth to the universe is the brief but tumultuous period that immediately followed it. How did the cosmos transform from a uniform sea of darkness into a chaotic swirl brimming with radiant stars? What were these first stars like, and how were they born? So far, we have very strong suspicions, but no hard answers. One reason is that the light from this period, called the cosmic dawn, is extremely faint, making it nearly impossible to infer the traits of t
