Astronomers have directly measured the mass of a dead star using an effect known as gravitational microlensing, first predicted by Einstein in his General Theory of Relativity, and first observed by two Cambridge astronomers 100 years ago. The international team, led by the University of Cambridge, used data from two telescopes to measure how light from a distant star bent around a white d

"All things are numbers," avowed Pythagoras. Today, 25 centuries later, algebra and mathematics are everywhere in our lives, whether we see them or not. The Cambrian-like explosion of artificial intelligence (AI) brought numbers even closer to us all, since technological evolution allows for parallel processing of a vast amounts of operations. Progressively, operations between scalars (num

Kleos Space has reached the milestone of daily product delivery collected from a strategically critical area of interest to its early adopter customers. RF data is collected by the Vigilance Mission (KSF1) satellites and is then processed through Kleos systems to generate intelligence products. The Vigilance Mission RF data collection satellites are in a sun synchronous low Earth orbit ena

LeoLabs, the leading commercial provider of Space Domain Awareness (SDA) services and low Earth orbit (LEO) mapping, announced the commissioning of the LeoLabs West Australian Space Radar (WASR). This radar site, located in Western Australia, adds critical coverage of the Southern Hemisphere in the Indo-Pacific region. WASR is the latest addition to LeoLabs network of phased array space ra

The Center for Quantum Science and Technology at Tel Aviv University has built the first ground station in Israel - and among the most advanced in the world - for tracking, sensing, hyperspectral imaging, and optical and quantum communication with satellites in orbit around the Earth. The station includes a satellite observatory dome with a diameter of 4.25 meters, a tracking system, a primary h

Researchers have theorised a new mechanism to generate high-energy 'quantum light', which could be used to investigate new properties of matter at the atomic scale. The researchers, from the University of Cambridge, along with colleagues from the US, Israel and Austria, developed a theory describing a new state of light, which has controllable quantum properties over a broad range of frequ

Spacemind, the space division of Italian company NPC, has achieved great success with a series of space launches. The three Italian nanosatellites, DanteSat, Futura-SM1, and Futura-SM3, have been successfully launched into orbit. This has also validated the operation of the new SMPod cubesat deployer, on-board equipments, and a larger version of the Artica deorbiting sail. Nicolo Benini, M

With temperatures on the moon ranging from minus 410 to a scorching 250 degrees Fahrenheit, it's an understatement to say that humans will need habitats with heat and air conditioning to survive there long term. But heating and cooling systems won't be effective enough to support habitats for lunar exploration or even longer trips to Mars without an understanding of what reduced gravity do

Astronomers using NASA's Hubble Space Telescope have for the first time directly measured the mass of a single, isolated white dwarf - the surviving core of a burned-out, Sun-like star. Researchers found that the white dwarf is 56 percent the mass of our Sun. This agrees with earlier theoretical predictions of the white dwarf's mass and corroborates current theories of how white dwarfs evo

Astronauts from NASA and Japan Aerospace Exploration Agency stepped out from the International Station to begin a spacewalk early Thursday to complete work started by another work team almost two weeks ago - part of a project to upgrade the station's power generation systems. NASA's Nicole Mann and JAXA's Koichi Wakata were tasked with finishing work on a mounting platform on one of th
