    M31 from LA. Stacked 40 x 3 min photos at 400mm with a Sigma 150-600 lens on a Nikon. There is a low neighborhood light glow to the right I couldn’t quite remove.

    This is the start to restoring our country. Here's something positive we can focus on doing: committing to reuniting families & providing all the support we can to them. Every last one of them.

    Nine parents deported by the Trump administration landed back into the U.S. Wednesday to reunite with children they had not seen in a year and a half. Some of the children were at the airport to greet them, including David Xol's 9-year-old son Byron.

    This is how you entrench inequality: We let the poor “invest” in lottery tickets, sports gambling and casinos but not startups. The first three are perennial losers. Startups have returned 15% over the past 50 years.

    Has anyone pointed out this whole issue with aliens and a Harvard Prof is private money in science from Milner who is keen on making contact or proving existence of aliens. Money + perks like private jets to Europe for media events can easily cloud one’s judgement. That’s all.

    Last time Trump was impeached for trying to cheat in his election, he was acquitted and escaped accountability. So what happened next? He tried to steal his election and subvert our democracy. Without accountability, it allows for it to happen again—by Trump or someone else.
