New Heat Sink Tested in Space Uses Melting Wax to Regulate Temperature July 10, 2025
It's cold in space, but overheating is a bigger problem than low temperatures. That's because the only way to regulate a spacecraft's heat is through radiation, or slowing down its computing. Engineers have tested a new type of heat sink in space that contains a wax-based phase change material that melts within the normal operating […]
Finding An Ocean On An Exoplanet Would Be Huge and the Habitable Worlds Observatory Could Do It July 10, 2025
The search for habitable exoplanets boils down to the search for water. Exoplanet scientists lack the technological capability to detect surface water on exoplanets from great distances, so instead they can only search for planets in habitable zones where surface water is likely. But what if we could directly detect the surface water itself?
Finding PBHs Using The LSST Will Be A Statistical Challenge July 10, 2025
With the recent first light milestone for the Vera Rubin observatory, it's only a matter of time before one of astronomy’s most long-awaited surveys begins. The Legacy Survey of Space and Time (LSST) is set to start on November 5th, and will scan the sky of billions of stars for at least ten years. One […]
NASA's Future Telescope Could Solve the Mystery of Life's Origins July 10, 2025
A team of scientists are preparing to use NASA's upcoming Habitable Worlds Observatory to answer one of the most profound questions of all time: How does life begin? Rather than searching for individual signs of life, the team plan to study patterns across dozens of exoplanets to test competing theories about the origins of life; […]
This Planet Makes Its Star Flare and the Planet Suffers Because Of It July 10, 2025
Astronomers have discovered hundreds of exoplanets on extremely short orbits of less than 10 days. Our Solar System has nothing like this, and these planets are so close to their stars that they can disrupt the stars' magnetic fields. Scientists think this can induce stellar flaring, and researchers have detected the first example of exoplanet-induced […]
