As far as we can tell, there’s no limit to how far it goes on; only a limit to how far we can see. Could the Universe truly be infinite?

The researchers applied the higher resonant radio frequency, which prompted any normal, “hot” fermions in the liquid to ring in response. The researchers then could zero in on the resonating fermions and track them over time to create “movies” that revealed heat’s pure motion — a sloshing back and forth, similar to sound waves.

“For the first time, we can take pictures of this substance as we cool it through the critical temperature of superfluidity, and directly see how it transitions from being a normal fluid, where heat equilibrates boringly, to a superfluid where heat sloshes back and forth,” Zwierlein says.

The experiments mark the first time scientists have been able to image second sound directly and the pure motion of heat in a superfluid quantum gas. The researchers plan to extend their work to map heat’s behavior more precisely in other ultracold gases. Then, they say their findings can be scaled up to predict how heat flows in other strongly interacting materials, such as high-temperature superconductors and neutron stars.

Minas, known for its Death Star like crater on its surface, is home to a relatively young ocean that’s influencing its orbit.

Last fall, NASA’s Mars rover spotted a massive spot on the surface of the Sun — and now, that ginormous maw is looking directly at the Earth.

First reported by SpaceWeather.com, the sunspot is expected to blast a coronal mass ejection (CME) out towards Earth and will be “not just a near miss, but an actual glancing blow.”

CMEs occur when storms on the surface of the Sun blast plasma out into the solar system, leaving planets in its path — including our own Earth — to handle the geomagnetic consequences.

For most of humanity’s existence, we have observed the universe using light, but these days photons aren’t the only game in town, says Chanda Prescod-Weinstein

The development of these solutions enables the necessary protection of critical program information from adversarial tamper efforts. Work will be performed in the continental United States and is expected to be completed Feb. 28, 2030. This contract was a competitive acquisition, and 20 offers were received. Fiscal 2024 research, development, test, and evaluation funds in the amount of $1,000 per awardee are being obligated at time of award. The Air Force Life Cycle Management, Wright Patterson Air Force Base, Ohio, is the contracting activity.

Roundhouse PBN LLC, Colorado Springs, Colorado, was awarded a $13,619,953 commercial, fixed-firm-price contract for a temporary and relocatable Program Integration Office/Program Management Office facility for the Sentinel Program at F. E. Warren Air Force Base, Wyoming. This contract provides for a one-time procurement for a secure, prefabricated, nominal 26,000-square-foot temporary facility, that will satisfy immediate requirements for additional office space for up to 200 Sentinel project personnel. This will be a commercial supply contract to procure a facility and furnishings, with a limited construction service component to conduct site preparation. Work will be performed at F.E. Warren AFB, Wyoming, and is expected to be completed by Feb. 7, 2025. This contract was a sole source acquisition. Fiscal 2024 operation and maintenance funds in the amount of $1,923,839; and fiscal 2024 procurement funds in the amount of $11,696,114, are being obligated at time of award.

Tesla has signed a deal with Choice Hotels International to bring chargers to thousands of additional hotels.

Over the last year, Tesla has become increasingly dominant in the charging space. It’s not like it wasn’t already, but with NACS, its own charge connector, becoming the standard in North America, and the release of its Universal Wall Connector, it is now extremely dominant.

The Tesla Universal Wall Connector is now becoming the top option for commercial level 2 installations as it can serve all EV owners now and it is future-proof for when everyone moves to NACS.

Two astrophysicists from the Laboratory for Space Research (LSR) at the University of Hong Kong (HKU) have finally solved a 20-year-old astrophysical puzzle concerning the lower-than-expected amounts of the element sulfur found in planetary nebulae (PNe) in comparison to expectations and measurements of other elements and other types of astrophysical objects.

The expected levels of sulfur have long appeared to be “missing in action.” However, they have now finally reported for duty after hiding in plain sight, as a result of leveraging highly accurate and reliable data. The team has recently reported their findings in The Astrophysical Journal Letters.

PNe are the short-lived glowing, ejected, gaseous shrouds of dying stars that have long fascinated and enthused professional and amateur astronomers alike with their colorful and varied shapes. PNe live for only a few tens of thousands of years compared to their host stars, which can take billions of years before they pass through the PN phase on the way to becoming white dwarfs.
