Re: APOD: Satellites over Orion (2021 Jun 01)

There is a silver lining here: I know these streaks are not starlink sats, but Spacex is poised to drop launch costs by 2-3 orders of magnitude with Starship. They are also leading the way in mass-manufacturing space hardware. The upshot is that for the cost of a hubble or JWST ($10 Billion), we wil...

Re: APOD: Southern Jupiter from Perijove 3 (2016 Dec 17)

It's beautiful, but for the love of Pete, WHEN will NASA give us pictures from 2500 km???? No perijove in the remaining orbits is lower than about 4200 km above the cloud tops. So you're not going to see anything at 2500 km until Juno is making its final dive into the planet on 2018 Feb 20. What I ...

I wonder why we don't see any lightning on the dark side? Too dim? Too infrequent?

Re: APOD: Giant Cluster Bends, Breaks Images (2015 Aug 23)

Question - What is the estimate for how far apart in time the separate images of the galaxy are? By my rough estimate, it looks they might only be a few tens of years apart at most. If they are truly that close in time, could this background galaxy be a special candidate for supernova studies? Presu...
