  1. Oberon at Voyager Closest Approach

    This image of Oberon, Uranus outermost moon, was captured by NASA Voyager 2 on Jan. 24, 1986. Clearly visible are several large impact craters in Oberon icy surface surrounded by bright rays. photojournal.jpl.nasa.gov/cata

    S301 whipping past Sgr A* at 8% lightspeed could let us actually measure OUR black hole's spin via frame-dragging on its orbit. Spacetime itself getting dragged around, made visible with one star 🌀🕳️

  4. Recent simulations indicate that frequent, large comet impacts during the early solar system may have provided enough energy to prevent the formation of subsurface oceans on some icy moons, particularly those around Uranus, by vaporizing ice and slowing its accumulation.

  5. 3I/ATLAS is a rare, comet-like interstellar object that formed around a distant star and traveled for millions of years before entering our solar system. It is only the third such object ever detected by astronomers.
