A group of Dysons made from solar panels will make the Earth inhabitant, suggesting research
Illustration of a Dyson herd artist. Credit: Archibald Tuttle As civilization becomes more and more sophisticated, so does their power needs. Advanced civilizations can require more force than they surround the host star with satellites collecting solar energy. These Dyson herds trap heat, so planets within the sphere can experience temperature rises. A new paper investigates this and concludes that…

Wolf-Rayet 104 “Pinwheel” star reveals surprise (and some relief)
The concept of the artist of the famous Wolf Rayette 104 “Pinwheel Star” previously known as “Death Star.” A new study conducted from Mauna Kea, Hawaii using three Keck Observatory equipment reveals that the orbits of the two stars are 30 or 40 degrees away from us, saving the planet from potential gamma ray bursts (GRB).

Crew launch to ISS Paves is a way for “stuck” astronauts ‘returns
This screen grab image from NASA’s live broadcast shows a SpaceX Falcon 9 rocket blowing up a Crew Dragon capsule from the Kennedy Space Center in Florida towards the International Space Station. It’s not long to go straight away. After more than nine months on the International Space Station, the two astronauts are one step closer to returning home after…

Atmospheric Wave Research Mission releases data from the first 3,000 orbits
This image shows awe awe data combined from the paths of two instruments over the US. The red and orange wave structures show an increase in infrared luminance (or radiance) produced by aero in the Earth’s atmosphere. Credit: NASA/AWE/LUDGER SCHERLIESS Following the 3,000th orbit of NASA’s adoration (Atmosphere Wave Experiment) on the International Space Station, researchers have publicly released the…

Easier proofreading of Cubesat constellations
A graphics that depict the mechanism of accuracy. Credit: Remote Sensing (2025). doi:10.3390/rs17030486 Cubesat offers many benefits. They are small, inexpensive and easy to replicate. However, these advantages have major drawbacks. They struggle to connect them to a wider constellations that can be more effective in observing or communicating tasks. The University of Albany team believes that using a customized…

Researchers develop glass sensors for Einstein telescopes
Jena researchers manufacture highly sensitive resonators made entirely of glass for the vibration sensors of the Einstein telescope. Credit: Fraunhofer IOF Starting in 2035, Einstein Telescope will be able to study gravitational waves with unprecedented accuracy. For telescopes, Jena researchers produced the first highly sensitive sensor made of glass. Gravitational waves are space-time distortions caused by extreme astrophysical events such…

Do you remember an asteroid that doesn’t hit the Earth? We can send a mission to explore it
The artist’s impression of the asteroid. Credit: ESA-Science Office Last year, astronomers detected asteroids near Earth (NEA) 2024 YR4, which orbit the Sun every four years and regularly cross the Earth’s orbit. The nature of the orbit makes it a potentially dangerous object (PHO). This means that one day it could pose a collision risk to the Earth. Recently, refined…
