Here, the first panel highlights thicker, curvier wisps at the edges of the nebula, while the second panel highlights straight lines. Researchers project that the latter may have been shot out hundreds of years earlier and at greater speeds than the shorter, curly lines. pic.twitter.com/DfCs62W4Hz

Explanation: A mere seven hundred light years from Earth, toward the constellation Aquarius, a sun-like star is dying. The dying star's last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution. Combining narrow band image data from emission lines of hydrogen atoms in red and oxygen atoms in blue-green hues, it shows tantalizing details of the Helix, including its bright inner region about 3 light-years across. The white dot at the Helix's center is this Planetary Nebula's hot, central star. A simple looking nebula at first glance, the Helix is now understood to have a surprisingly complex geometry.
Yea I'm not entirely sure, looks like I was wrong, it's slated for ~3.5 hrs from now. Although that might be just the first launch window opening.bmks270 said:Jock 07 said:bmks270 said:
Anybody know Relativity's launch window? For all of their hype and marketing they haven't published a date on their website which still says 2022. They raised their rocket on the launch pad today.
ABL Space Systems launch window for their 1st rocket opened today, but is on hold due to a weather system. They've had 3 scrubbed attempts so must be pretty anxious to get those engines firing.
Supposed to go either overnight tonight or early tomorrow iirc, but wouldn't hold your breath. It's been on the docket for at least a few months now and keeps getting pushed.
I don't get it, they are a hype machine but a window time isn't posted on their website even though it's in the next day or two? I thought they wanted people to watch?

Other than Tim, the rest of the dear moon crew seems insufferable.
They don't seem like the type that will work well together to fix any technical, engineering issues during a trip around the moon.

Physicists have purportedly created the first-ever wormhole, a kind of tunnel theorized in 1935 by Albert Einstein and Nathan Rosen that leads from one place to another by passing into an extra dimension of space.
The wormhole emerged like a hologram out of quantum bits of information, or "qubits," stored in tiny superconducting circuits. By manipulating the qubits, the physicists then sent information through the wormhole, they reported today in the journal Nature.
The team, led by Maria Spiropulu of the California Institute of Technology, implemented the novel "wormhole teleportation protocol" using Google's quantum computer, a device called Sycamore housed at Google Quantum AI in Santa Barbara, California. With this first-of-its-kind "quantum gravity experiment on a chip," as Spiropulu described it, she and her team beat a competing group of physicists who aim to do wormhole teleportation with IBM and Quantinuum's quantum computers.
When Spiropulu saw the key signature indicating that qubits were passing through the wormhole, she said, "I was shaken."
The experiment can be seen as evidence for the holographic principle, a sweeping hypothesis about how the two pillars of fundamental physics, quantum mechanics and general relativity, fit together. Physicists have strived since the 1930s to reconcile these disjointed theories one, a rulebook for atoms and subatomic particles, the other, Einstein's description of how matter and energy warp the space-time fabric, generating gravity. The holographic principle, ascendant since the 1990s, posits a mathematical equivalence or "duality" between the two frameworks. It says the bendy space-time continuum described by general relativity is really a quantum system of particles in disguise. Space-time and gravity emerge from quantum effects much as a 3D hologram projects out of a 2D pattern.
