NLEOMF reports 15% increase in officer fatalities halfway through 2024

The spike was primarily driven by traffic-related incidents, which caused a total of 26 LEO deaths in 2024 – a 136% increase compared with the same period last year

Deep-mapping the night sky for hot stars

The next NASA space telescope to survey the ultraviolet sky has the fingerprint of an astronomer from the Institute of Science and Technology Austria (ISTA). Assistant Professor Ylva Götberg is part of a large international collaboration that will study how galaxies and stars evolve, and create a community resource dataset of the entire sky. Götberg […]

Astronomers suggest up to 60% of near-Earth objects could be dark comets

Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have been one route for delivering water to Earth, according to a University of Michigan study.

Using microwave sintering to produce ‘space brick’ for a future moon base

The recent discovery of energy resources on the moon, such as water ice, has refocused interest on its potential as a sustainable hub for space exploration. NASA has also announced the Artemis mission, aiming for long-term human presence on the lunar surface. However, infrastructure expansion, such as lunar base construction, plays a vital role.

Astronomers find the nearest massive black hole, a missing link in massive black hole formation

Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed to exist: intermediate-mass black holes, formed in the early stages of galaxy evolution.

Researchers more precisely calculate how much faster time passes on the moon

A team of physicists with NASA’s Jet Propulsion Laboratory at the California Institute of Technology has calculated more precisely how much faster time passes on the moon than on the Earth. The paper describing the math they used to make the calculations and their results has been posted to the arXiv preprint server.

Physicists move one step closer to topological quantum computing

A team of experimental physicists led by the University of Cologne have shown that it is possible to create superconducting effects in special materials known for their unique edge-only electrical properties. This discovery provides a new way to explore advanced quantum states that could be crucial for developing stable and efficient quantum computers.

Study demonstrates generation of orbital current via magnetization dynamics

Electrons inherently carry both spin and orbital angular momentum (i.e., properties that help to understand the rotating motions and behavior of particles). While some physicists and engineers have been trying to leverage the spin angular momentum of electrons to develop new technologies known as spintronics, these particles’ orbital momentum has so far been rarely considered.

Two historians claim the Ancient Egyptians did not build the Pyramids

The historians and authors of a ‘controversial’ forthcoming book firmly believe there is a strong possibility a second ‘Great Sphinx’ remains buried at the Giza plateau and suggest the Great Pyramid at Giza were built thousands of years earlier than previously thought, and not by the ancient Egyptians.

Two historians have questioned whether the […]

Modeling study proposes a diamond layer at the core-mantle boundary on Mercury

A recent study in Nature Communications by scientists from China and Belgium suggests that Mercury’s core-mantle boundary (CMB) includes a diamond layer, potentially up to 18 kilometers thick, deep within the planet’s interior.

Study investigates the nature of very-high energy gamma-ray source TeV J2032+4130

Using the High-Altitude Water Cherenkov (HAWC) observatory, an international team of astronomers has observed a very-high energy gamma-ray source designated TeV J2032+4130. Results of the observational campaign, presented July 3 on the preprint server arXiv, provide crucial information regarding the nature of this source.

Visualizing the boundary modes of the charge density wave in a topological material

Charge density waves are quantum phenomena occurring in some materials, which involve a static modulation of conduction electrons and the periodic distortion of the lattice. These waves have been observed in numerous condensed matter materials, including high-temperature superconductors and quantum Hall systems.
