SpaceX’s Falcon Heavy launched classified payloads for the U.S. Space Force on its fourth-ever mission on Nov. 1, 2022. Relive the highlights.
Is solar geoengineering an alternative solution to the climate crisis?
Solar geoengineering is a branch of geoengineering that focuses on reflecting sunlight back into outer space to reduce global warming. There are several solar geoengineering techniques being researched; the most feasible one consists of spraying reflective aerosols in the stratosphere.
Thermodynamic phases governed by the strong nuclear force have been linked together using multiple theoretical tools.
Quantum chromodynamics (QCD) is the theory of the strong nuclear force. On a fundamental level, it describes the dynamics of quarks and gluons. Like more familiar systems, such as water, a many-body system of quarks and gluons can exist in very different thermodynamic phases depending on the external conditions. Researchers have long sought to map the different corners of the corresponding phase diagram. New experimental probes of QCD—first and foremost the detection of gravitational waves from neutron-star mergers—allow for a more comprehensive view of this phase structure than was previously possible. Now Tuna Demircik at the Asia Pacific Center for Theoretical Physics, South Korea, and colleagues have put together models originally used in very different contexts to push forward a global understanding of the phases of QCD [1].
Phase transitions governed by the strong force require extreme conditions such as high temperatures and high baryon densities (baryons are three-quark particles such as protons and neutrons). The region of the QCD phase diagram corresponding to high temperatures and relatively low baryon densities can be probed by colliding heavy ions. By contrast, the region associated with high baryon densities and relatively low temperatures can be studied by observing single neutron stars. For a long time, researchers lacked experimental data for the phase space between these two regions, not least because it is very difficult to create matter under neutron-star conditions in the laboratory. This difficulty still exists, although collider facilities are being constructed that are intended to produce matter at higher baryon densities than is currently possible.
By plotting nonlinear trajectories through a GAN’s latent space, the method enables certain image attributes to vary while others are held fixed.
China is the first country to operate a space station on its own.
China is one step closer to completing its space station after it launched the third and final module to orbit aboard a Long March 5B rocket, a Bloomberg report.
The rocket took off from Wenchang Satellite Launch Center on Hainan Island at 3:37 p.m. local time Monday, October 31. The payload it lifted to orbit is the Mengtian laboratory module, which will complete China’s orbital station. rocket took off from Wenchang Satellite Launch Center on Hainan Island at 3:37 p.m. local time Monday, October 31.

Our solar system is just a small slice of the universe. From the depth that James Webb’s first images have provided, to the journeys that Voyager 1 and Voyager 2 have taken into interstellar space, our universe is much bigger beyond our solar system’s edge.
Why the Pillars of Creation has fascinated the public since 1995.
The Pillars of Creation was an image special enough to be featured on a U.S. postage stamp to commemorate the Hubble Space Telescope and its namesake, astrophysicist Rogier Windhorst tells Inverse.
Here is a guide to the stunning Pillars of Creation and why one space telescope veteran stands by the scene’s remarkability.

The project, known as DAF-MIT AI Accelerator, selected a pilot out of over 1,400 applicants.
The United States Air Force (DAF) and Massachusetts Institute of Technology (MIT) commissioned their lead AI pilot — a training program that uses artificial intelligence — in October 2022. The project utilizes the expertise at MIT and the Department of Air Force to research the potential of applying AI algorithms to advance the DAF and security.
The military department and the university created an artificial intelligence project called the Department of the Air Force-Massachusetts Institute of Technology Artificial Intelligence Accelerator (DAF-MIT AI Accelerator).

The mission to explore a metallic asteroid could launch in October 2023.
The agency announced on October 28 that after months of scrutiny, an independent review board has decided it’s possible to move forward with the Psyche mission — humanity’s first venture to a metallic asteroid, 16 Psyche.
What’s New – The Psyche mission is now on track to launch in October 2023, which means it could reach its namesake destination in August 2029 after a gravity-assist swing past Mars in 2026. In the meantime, the mission team is testing the spacecraft’s flight software, something that became a sticking point back in June when NASA realized that Psyche stood no chance of being ready in time for its original mid-October 2022 launch date.

The resulting five-minute audio includes eerie creaks and crackling sounds, as well as deep breathing-like sounds that listeners on social media described as “petrifying” and “spine tingling freaky.”
Since the discovery was revealed on October 24, loudspeakers at Solbjerg Square in Copenhagen, Denmark, have broadcasted the recording three times a day. Plans are to continue playing it each day at 8 a.m., 1 p.m., and 7 p.m. through October 30.
