    Garbage compactor heading to space station

    A prototype trash compactor will be tested on the International Space Station in 2026. Credit: Sierra Space Astronauts on the International Space Station emit a fair amount of trash, fill cargo ships, deorbit, and burn up in the atmosphere. Now, Sierra Space has been awarded a contract to build a trash compactor for the space station. The device compresses space…

  • Powerful New Satellites From Us And India Track Earth's Changing

    Powerful new satellites from US and India track Earth’s changing surface

    NISAR’s mission will help researchers study how the Earth’s surface changes over time, including the lead-up to the pictured volcanic eruption at Redoubt Mountain in southern Alaska in April 2009. It will help you understand more deeply. Credit: RG McGimsey/AVO/USGS Data from NISAR improves our understanding of phenomena such as earthquakes, volcanoes, landslides, and damage to infrastructure. Although we don’t…

  • Investigating How Stellar Threats Affect The Habitable Zone Of Exoplanets

    Investigating how stellar threats affect the habitable zone of exoplanets

    This image from the study shows the sky positions of exoplanet-dominated stars projected onto the Mollweide map. The HZS is indicated by a yellow-green circle, and the remaining exoplanet population is represented by a gray circle. The studied sample of 84 HZS located within 220 parsecs of the Sun is represented by a yellow-green cross circle. The three dense HZSs…

  • How Many More Exoplanets Are There In Known Systems?

    How many more exoplanets are there in known systems?

    Consider seven planetary systems. Credit: arXiv (2024). DOI: 10.48550/arxiv.2411.00245 One thing we’ve learned in recent decades is that exoplanets are surprisingly common. So far we have confirmed about 6,000 planets, and there is evidence for thousands more. Most of these planets were discovered using the transit method. Although there are other methods. Many stars are known to have multiple planets,…

  • Webb Confirms Long Standing Galaxy Model

    Webb confirms long-standing galaxy model

    JWST image of the grand design spiral galaxy NGC 628. Credit: NASA / ESA / CSA / Judy Schmidt (CC BY 2.0) Perhaps the greatest tool astronomers have is the ability to go back in time. Because starlight takes time to reach us, astronomers can observe the history of the universe by capturing the light of distant galaxies. This is…

    Learn more about supernovae through stardust

    A pair of presolar particles from the Murchison meteorite. Credit: Argonne National Laboratory, Department of Energy Most of the diverse elements in the universe are born from supernovae. We are literally made from the dust of long-dead stars and other astrophysical processes. But the details of how that happens are what astronomers are still trying to understand. How do the…
