    This mind-blowing simulation by Jacob Kegerreis (of ) shows how an ancient, giant impact of Uranus could've led its 98° tilt & wildly mixed up interior structure. As perhaps the least understood planet, it needs a mission! Let's support 🚀

    The fantastic voyage continues! One year ago this week, Voyager 2 joined me in interstellar space. Today, five papers published detailing my twin's findings in the region just beyond the bubble created by our Sun.

    Published in Nature Astronomy today, five papers reporting the measurements from Voyager 2 as it crossed from the heliosphere into interstellar space. For an overview, a good place to start is the News & Views from Du Toit Strauss:

    Here are the planets & dwarf planets in the solar system that have been fully mapped (except Pluto which is partially mapped). Dozens of other dwarf planet candidates beyond Pluto are yet to be seen up close. Youtube HD

    A graph of the path of the interstellar comet 2I/Borisov through the sky. You can see how valuable the precovery data is (each epoch is marked), and how everything interesting in the next year will happen in the South.

    OK, let's have a look on the latest 3D shape model (Nature Astronomy, ) for (10) Hygiea and how it looks when the object rotates.

    Perhaps. Just perhaps. We may get a second shot at visiting Pluto in my lifetime. Magnificent !!.

    When visited Pluto it left more ?s than answers, but 1 thing was sure - the need to go back. Now, NASA has asked to begin studying & developing a mission to do it, to prepare for the next Planetary Science Decadal Survey:

    If we could predict stellar occultations by comet 2I/Borisov with some reasonable accuracy the favorable time window for observing them will be between 2020 mid March and mid May wrt to the max. occultation duration. But it would happen on the southern hemisphere.
