It’s been about eight months since the Vera Rubin Observatory (VRO) saw first light. Now the telescope is scanning the night sky to detect transient changes and sending alerts to astronomers and observatories around the world so they can perform follow-up observations. This alert system is one of the last milestones before the VRO starts […] While sifting through the extensive data collected by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft over the last decade, scientists discovered a familiar type of electromagnetic signal commonly caused by lightning. This rare find represents the first direct indication of lightning activity on Mars. The team recently published their findings in Science Advances, where […] An international team of astronomers has carried out photometric and spectroscopic observations of SN 2024abvb—a recently discovered supernova of a rare Type Icn. The new observational campaign yields important information regarding the properties and nature of this supernova. The study was published February 18 on the arXiv pre-print server. Go to Source […] Imagine trying to reconstruct the history of a city by studying only its oldest surviving buildings. You can’t watch it being built, you can’t interview the architects, all you have are the structures themselves, their materials, their arrangement, the subtle clues locked into their very fabric. That is essentially what astronomers do when they study […] As part of a golden age of exploration and discovery, NASA announced Friday the agency is increasing its cadence of missions under the Artemis program to achieve the national objective of returning American astronauts to the moon and establishing an enduring presence. This includes standardizing vehicle configuration, adding an additional mission in 2027, and undertaking […] Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected. It is located in a violently merging galaxy more than 8 billion light-years away, opening a new radio astronomy frontier. Go to Source It is one of the most famous questions in science, and it was asked, as legend has it, over lunch. Enrico Fermi, the physicist who helped build the first nuclear reactor and whose name graces a unit of length so small it makes an atom look generous, was chatting with colleagues about the possibility of […] Here’s a thought experiment that keeps planetary scientists awake at night. Strip every living thing from our planet, every bacterium, every blade of grass, every creature that has ever drawn breath and ask a simple but profound question: Would Earth still be a world capable of supporting life? Go to Source There have been plenty of attempts to resolve the “Hubble Tension” in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on different values depending on how you measure it. A new NASA Institute for Advanced Concepts (NIAC) Phase I report on the Cosmic Positioning […] NASA’s Curiosity Mars rover discovered these bumpy, pea-sized nodules while exploring a region filled with boxwork formations—low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in between. This mosaic is made up of 50 individual images taken by Curiosity’s Mars Hand Lens Imager (MAHLI), a camera on the […] In this age of Mars rovers, questions about the planet’s ancient past have shifted. A growing body of evidence supports the idea that Mars was once warm and wet. Now researchers are focused on the timeline of the red planet’s watery past. Research efforts all come down to the ultimate question regarding the planet: Did […] Scientists might have just found Earth’s icy, distant cousin a few hundred million light-years away. HD 137010 b is one of thousands of exoplanets, or planets that orbit other stars, and is potentially the first Earth-like one that also orbits a sun-like star. Initially observed in 2017 with data from the National Aeronautics and Space […] Planetary systems such as our solar system take hundreds of millions of years to evolve. Since humanity has only existed for a sliver of that time, astronomers have only observed planetary systems at birth or, more often, long after they have settled into adulthood. There is an information gap about what happens in the middle. […] NASA said Friday it’s adding an extra moon mission by Artemis astronauts before attempting a high-risk lunar landing with a crew. Go to Source 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 […] |
