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…

Global rooftop solar panels could potentially cool the earth at 0.13°C, modeling studies suggest
Maps the roofs of buildings in selected global regions. Credit: Natural Climate Change (2025). doi:10.1038/s41558-025-02276-3 Working with one colleague in Singapore and a colleague at MIT, an interdisciplinary team from many institutions across China have discovered evidence suggesting that solar panels can be installed on every rooftop in the world and can replace traditional power sources. In a paper published…

New analysis of asteroid dust reveals evidence of salt water in the early solar system.
In October 2020, a bans -size robot spacecraft temporarily touched the surface of Benne, a 525 -meter planet, 32 million kilometers from the earth. As part of NASA’s OSIRIS-REX mission, spacecraft not only spent two years of imaging as an planet, but also collected valuable samples of dust and small rocks from the poor surface of Bennu. In September 2023,…

Space researchers build signal system to warn of dangerous solar storms
Credit: Pager Researchers have created an improved signaling system to predict geomagnetic storms. They are currently testing how well these algorithms can prepare us for space storms that could wreak havoc by knocking out satellites in space and power grids on Earth. . Yuri Shprits, a space scientist at the German Earth Science Research Center in Potsdam, is on a…

Tether covered with solar panels could accelerate ISS orbit
Power diagram of the BPT tether system on the ISS. Credit: Acta Astronautica (2024). DOI: 10.1016/j.actastro.2024.12.031 The ISS’s orbit is slowly decaying. Although it may seem like a permanent fixture in the sky, the orbiting space laboratory is only about 400 km above the planet. There may not be much atmosphere at that altitude. However, some are still present, and…

Image: NASA’s Terra satellite captured the shadow of the 2015 solar eclipse.
Credit: NASA Goddard MODIS Rapid Response Team On the morning of March 20, 2015, a total solar eclipse was visible in parts of Europe, and a partial solar eclipse was visible in North Africa and northern Asia. NASA’s Terra satellite passed over the Arctic Ocean on March 20 at 10:45 a.m. UTC (6:45 a.m. EDT), capturing the shadow of the…

Two clusters of dark comets in our solar system could tell researchers where Earth’s oceans are located
Dark comets fly through space, but unlike comets, they do not have dust tails. Credit: Adina Feinstein and NASA Earth Observatory The water that makes up the oceans served as an important element for the development of life on Earth. But scientists still don’t know where the water on Earth comes from in the first place. One leading idea is…
