Deflecting Asteroids Isn't Simple According to New Data from DART

We know that there are many asteroids in the Solar System that pose a potential threat. We're getting better at detecting them, and every few months we learn of another one on a potential course to strike Earth. It's obviously in our best self-preservation interest to detect these objects and to figure out how to protect the planet from them. That's what led to NASA's DART (Double-Asteroid Redirection Test).

Finding PBHs Using The LSST Will Be A Statistical Challenge

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 of the most important things it hopes to find is evidence (or lack thereof) of primordial black holes (PBHs), one of the primary candidates for dark matter. A new paper from researchers at Durham University and the University of New Mexico looks at the difficulties the LSST will have in finding those enigmatic objects, especially the statistical challenges, and how they might be overcome.

The search for atmospheric biosignatures takes a backseat to the search for water.
