Woven across our universe is a weblike structure of galaxies called the cosmic web. Galaxies are strung along filaments in this vast web, which also contains enormous voids. Now, astronomers using Webb have discovered an early strand of this structure, a long, narrow filament of 10 galaxies that existed just 830 million years after the big bang. The 3 million light-year.
A light year is the distance that a particle of light (photon) will travel in a year—about 10 trillion kilometers (6 trillion miles). It is a useful unit for measuring distances between stars.
The ARCAFF project aims to use deep learning AI to make better predictions of space weather events and calculate how probable these predictions are, to help protect vital technology and infrastructure.
A new project led by the Dublin Institute for Advanced Studies (DIAS) is using AI as a way of getting faster and more accurate warnings about space weather events like solar flares.
These solar flares have the potential to disrupt vital technologies and infrastructure, including radio communications, electrical power grids and navigation systems. They can also present risks to spacecraft and astronauts.
Space propulsion company Pulsar Fusion has started construction on a large nuclear fusion chamber in England, as it races to become the first firm to fire a nuclear fusion-powered propulsion system in space.
Nuclear fusion propulsion tech, arguably a golden goose of the space industry, could reduce the travel time to Mars by half and cut the travel time to Titan, Saturn’s moon, to two years instead of 10. It sounds like science fiction, but Pulsar CEO Richard Dinan told TechCrunch in a recent interview that fusion propulsion was “inevitable.”
“You’ve got to ask yourself, can humanity do fusion?” he said. “If we can’t, then all of this is irrelevant. If we can — and we can — then fusion propulsion is totally inevitable. It’s irresistible to the human evolution of space. This is happening, because the application is irresistible.”
We live in an era of renewed space exploration, where multiple agencies are planning to send astronauts to the Moon in the coming years. This will be followed in the next decade with crewed missions to Mars by NASA and China, who may be joined by other nations before long.
These and other missions that will take astronauts beyond Low Earth Orbit (LEO) and the Earth-Moon system require new technologies, ranging from life support and radiation shielding to power and propulsion.
And when it comes to the latter, Nuclear Thermal and Nuclear Electric Propulsion (NTP/NEP) is a top contender!
This metallic gel is made from a mixture of micron-scale copper particles suspended in water and a small amount of a liquid indium-gallium alloy.
The origins of three-dimensional (3D) printing can be traced back to the 1970s when Johannes F Gottwald patented the Liquid Metal Recorder. This device used continuous inkjet technology to create metal objects that could be removed and reused or melted down for printing again.
Since then, innovations in 3D printing have happened at an unprecedented speed, with the most recent reports of 3D-printed Lamborghini and 3D-printed rocket engines.
Camera sensitive enough to spot a single photon finally achieved by researchers in colorado.
A team of researchers from the National Institute of Standards and Technology in Boulder, Colorado, has successfully developed a super-sensitive camera capable of detecting a single photon.
This remarkable achievement opens up new avenues for scientific exploration and holds significant potential for applications in quantum computing, communications, space exploration, and medical research.
The billionaire space race is continuing to expand across the globe. Jeff Bezos-owned Blue Origin has announced plans to expand its operations to “Europe and beyond,” the Financial Times reports. Part of this growth hinges on finding a site for an international launch facility — the company has already put down roots in Texas, Washington, Florida and Alabama — but the new location hasn’t been chosen yet. It’s also actively looking for fresh acquisitions and partnerships outside of the US in areas such as manufacturing and software.
“We’re looking for anything we can do to acquire, to scale up to better serve our customers,” Bob Smith, Blue Origin CEO, said. “It’s not a function of size — rather how much it accelerates our road map of what we’re trying to get done.” Last year, Blue Origins bought New York-based Honeybee Robotics, a move that appears successful: The space-based robotics company was part of the Blue Origin team that recently received $3.4 billion to build the lunar lander for NASA’s third Artemis mission. Blue Origin’s biggest competitor, Elon Musk’s SpaceX, is handling the first and second Artemis moon landings.
Though Blue Origin was the first to launch, land and reuse a rocket successfully, it has fallen behind its rival due to hold-ups with building its launchers. Blue Origin’s plans for a more global footprint might help them catch up with SpaceX’s progress. Amazon’s Project Kuiper also plans to use Blue Origin’s rocket New Glenn for at least 12 launches between 2024 and 2029 after a few years of delays.
Using the Spektr-RG (SRG) spacecraft and the Zwicky Transient Facility (ZTF), an international team of astronomers has discovered a new eclipsing cataclysmic variable system, which received designation SRGeJ045359.9+622444 (or SRGeJ0453 for short). The finding is reported in a paper published June 22 on the pre-print server arXiv.
Cataclysmic variables (CVs) are binary star systems consisting of a white dwarf primary that is accreting matter from a normal star companion. They irregularly increase in brightness by a large factor, then drop back down to a quiescent state. These binaries have been found in many environments, such as the center of the Milky Way galaxy, the solar neighborhood, and within open and globular clusters.
AM CVn stars (named after the star AM Canum Venaticorum), are a rare type of CV in which a white dwarf accretes hydrogen-poor matter from a compact companion star. In general, such systems are helium-rich binaries, not showing traces of hydrogen in their spectra, with orbital periods between five and 65 minutes.
A fully electric flying car that’ll cost about $300,000 just won approval to start testing on the road – and in the air.
Alef Aeronautics, a Californian automaker, said in a press release it had received a Special Airworthiness Certification from the Federal Aviation Administration (FAA) for the Model A.
It’s the first such approval for a flight-capable car, according to the startup, which has been backed by the likes of SpaceX.
