    Here we are, alone in space on a spaceship we call Earth. I am disheartened; I thought by now we would have found our cosmic brothers and sisters to share our challenges, joys, and defeats with. But no, we are floating in this galaxy, arguing about our tiny lives and wasting the

    AI is invading many fields in astronomy, SETI as well. Researchers at Breakthrough Listen have now used machine learning to discover 72 new fast radio bursts from a mysterious source some 3 billion light years from Earth. buff.ly/2QjOKOc

    It's hard to tell who's seeking attention in this tweet: the author fabricating a tale, the fictional woman who supposedly can't die unless she eats an apple due to an allergy, or the fictional passenger who just happened to have an apple in his bag—a common occurrence, right?

    Science is a window to the vast universe of facts that could change the world while social media is a key hole to an alternate reality for too many of us. We need to work together to change this, but I still wonder if bringing more science to social media is a solution. Thoughts?

    Confirmation from my colleague Peter Jenniskens that four Polish meteorite hunters reported to have found fragments of the asteroid #2024BX1, which burned above Germany last saturday. Initial assessments are that they are Eucrites, pieces of the large main-belt asteroid Vesta.

    Most of Gen X are parents who faced the 2008 financial crisis head-on, then watched as our kids struggled through pandemic restrictions. Now, we’re the generation with a last chance to push for change, like a final and potentially disastrous, Hail Mary.

    I’m definitely voting for Biden after seeing this video. I can't handle four years of terrible taste and bad ideas in the @WhiteHouse.
