The future of enterprise tech won’t be confined to the data center mothership — nor even the public cloud. Wedded to the internet of things, edge computing puts processing horsepower wherever it needs to go.
The twisting patterns created by the multiple spiral arms of NGC 2835 create the illusion of an eye. This is a fitting description, as this magnificent galaxy resides near the head of the southern constellation of Hydra, the water snake. This stunning barred spiral galaxy, with a width of just over half that of the Milky Way, is brilliantly featured in this image taken by the NASA /ESA Hubble Space Telescope. Although it cannot be seen in this image, a supermassive black hole with a mass millions of times that of our Sun is known to nestle in the very center of NGC 2835.
This galaxy was imaged as part of PHANGS-HST, a large galaxy survey with Hubble that aims to study the connections between cold gas and young stars in a variety of galaxies in the local Universe. Within NGC 2835, this cold, dense gas produces large numbers of young stars within large star formation regions. The bright blue areas, commonly observed in the outer spiral arms of many galaxies, show where near-ultraviolet light is being emitted more strongly, indicating recent or ongoing star formation.
Expected to image over 100 000 gas clouds and star-forming regions outside our Milky Way, this survey hopes to uncover and clarify many of the links between cold gas clouds, star formation and the overall shape and morphology of galaxies. This initiative is a collaboration with the international Atacama Large Millimeter/submillimeter Array (ALMA) and the European Southern Observatory’s Very Large Telescopes MUSE instrument, through the greater PHANGS program (PI: E. Schinnerer).
Blue Origin’s human lunar lander all-star space team completes first key milestone for moon mission – TechCrunch.
Blue Origin, along with it partners Lockheed Martin, Northrop Grumman and Draper, was one of three companies to be awarded contracts by NASA to develop human lunar landers for future moon missions. Blue Origin’s so-called “National Team” is focused on developing a Human Landing System (HLS) for NASA to support its efforts to return human astronauts to the surface of the moon by 2024, and today it announced that along with its partners, it has achieved the first crucial step of defining the requirements of the mission, including any space and ground vehicles used.
This is a key first step, which amounts to having established a checklist of thousands of items that will make up the parameters of the National Team’s HLS mission. It means that the company can now move ahead to further NASA reviews (it has already agreed with the agency on a number of the proposed design and build standards) and ultimately, the preliminary design phase.
The Starship, SpaceX’s under-construction giant rocket, is about to tackle a big new challenge.
In the first experiment to take advantage of a new technology for producing powerful attosecond X-ray laser pulses, a research team led by scientists from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University showed they can create electronic ripples in molecules through a process called “impulsive Raman scattering.”
Exploiting this unique interaction will allow scientists to study how electrons zipping around molecules kick off key processes in biology, chemistry, materials science and more. The researchers described their results in Physical Review Letters.
Typically, when X-ray pulses interact with matter the X-rays cause the molecules’ innermost “core” electrons to jump to higher energies. These core-excited states are highly unstable, decaying in just millionths of a billionth of a second. In a majority of X-ray experiments, that’s how the story ends: The excited electrons quickly return to their rightful places by transferring their energy to a neighboring electron, forcing it out of the atom and producing a charged ion.

Microsoft’s unusual experiment in the sea off Orkney seems to have provided some valuable lessons.
Three physicists won a $3 million Breakthrough prize for proving there is no fifth force (that we know of). And it all started with a series of table-top experiments using cheap equipment.
Eric Adelberger, Jens Gundlach and Blayne Heckel together lead the “Eöt-Wash Group,” which is devoted to precise tests of physical laws. They take their name from the early-1900s physicist Loránd Eötvös and the University of Washington, where they work. These Eöt-Wash researchers got their start in the mid-1980s, using a device known as a “torsion balance” to disprove claims of an undiscovered fifth force in physics. Since then, they’ve used more elaborate versions of the same device to test the true strength of gravity, detect the tug of dark matter in the Milky Way and search for theoretical physical effects like extra dimensions and “axion wind.”

Astronomers have detected a stinky gas on Venus called phosphine, and weirdly enough, it could be a sign of alien life in the planet’s clouds. It’s still too early to say for sure that Venus hosts life forms, but the discovery opens up a lot of questions about what’s happening on Earth’s neighbor.
