An international team of scientists led by the Institute of Cosmos Sciences at the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC) has presented REGALADE, an unprecedented catalogue covering the entire sky and bringing together nearly eighty million galaxies. The work, published in the journal Astronomy & Astrophysics, marks a turning point for astronomy and opens up a new scenario that allows researchers to explore cosmic events with a degree of precision never before achieved.

Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it’s more difficult. This is something physicists from Poland and the UK are well aware of. To improve current simulations of high-energy particle collisions, they have developed a more accurate method for estimating the impact of calculations that are... not performed.

The New York Consortium for Space Technology (NYCST) is led by Cornell University and funded by the U.S. Department of Defense’s Office of Local Defense Community Cooperation through the Defense Manufacturing Community Support Program.

Just a few days in simulated microgravity can subtly change the way women’s blood clots, sparking bigger questions about health monitoring protocols for astronauts who can spend six months or more in orbit, say Simon Fraser University researchers. First reported in 2020, an International Space Station mission detected an unexpected blood clot in a female astronaut’s jugular vein. To date, space-health research has had more male participants but with the number of female astronauts on the rise, a new SFU–European Space Agency study examined how microgravity affects blood clotting specifically in women.

An international team of scientists, led by a PhD researcher from Northumbria University, has made groundbreaking discoveries about a spectacular feature of Jupiter’s northern lights, revealing a never-before-seen temperature structure and dramatic density changes within the top of the giant planet’s atmosphere. 

New study reveals that even small differences in solar magnetic activity produce detectable changes inside the Sun.

Birds, like other animals, need safe and warm places to sleep. Cozying up in groups can be an effective way to maintain vigilance, conserve heat, and gather information about where to find their next meal. A new study published in the Journal of Raptor Research titled “Use of GPS Telemetry System to Study Communal Roosts in a Neotropical Raptor”tracked 24 Chimango Caracaras (Milvagro chimango) to study their resting, or “roosting” behaviors during the breeding season. Studies like this shed light on what is called the “spatial ecology” of an animal, meaning how organisms are distributed, how they use and move through space, and how interactions between other caracaras and other species unfold as a result. Such information helps biologists understand the importance of particular habitats, as well as how species adapt to changing landscapes.  

Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), have used data from the project to make the largest, most accurate 3D map yet of the light emitted by excited hydrogen in the early universe, 9 billion to 11 billion years ago. The map brings into view faint galaxies and gas, adding shape and nuance to this formative era in our universe.
