Researchers in Munich have used the Large Binocular Telescope in Arizona to capture five images of one and the same supernova in a single picture. The gravity of two foreground galaxies has deflected the light from a supernova far in the background along different paths to Earth.
Star dust is at the root of everything that exists, and is produced in large quantities around Wolf-Rayet binaries. But there are some puzzling observations of dust grain sizes that require explanations. New research shows why different observations have found different dust grain sizes.
Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers melted fake lunar soil—a synthetic version of the fine dusty material on the moon surface, called regolith simulant—into layers and fused it with a base surface to manufacture small, heat-resistant objects.
SpaceX's Starship is the most powerful rocket ever built and it may be about to change everything. But researchers at the German Aerospace Centre have been asking a question: does Europe have an answer? Their new study, built on meticulous analysis of Starship's own flight data, suggests the answer is yes although it will require a fundamentally different approach, and a willingness to think differently.
Future farmers on the Moon and Mars will have a big challenge: how to grow healthy food in two extremely unhealthy environments. That's because the soil on both worlds isn't at all hospitable to plants and animals. Neither are other conditions. Both are irradiated worlds, Mars has a thin atmosphere and the Moon has none at all. So, how will future colonists on either world grow their food?
Jupiter is the largest planet in the solar system and has proudly boasted about this since time immemorial, with its scientific confirmation occurring by Galileo Galilei in 1610. It was later found that Jupiter has a bulging equator caused by its rapid rotation, turbulent atmosphere, and complex interior mechanisms despite its massive size, and scientists have even measured its “waistline” down to a tenth of a kilometer. Now, imagine being the largest planet in the solar system and you’re told you’re not as big as you thought. Where probably most humans would be thrilled to find this out, how do you respond if you’re Jupiter?
The radio telescope LOFAR, with a major contribution from Leiden Observatory, has produced the most detailed radio map of the Universe ever made. Never before have so many cosmic radio sources been captured in a single survey: 13.7 million.
