Milky Way, Meteor, Meteorology
But had I known about this picture, I mightâve picked it instead:
Click that to embiggen it! When you do, youâll see why I like it. The Milky Way glows over the landscape, the combined might of billions of stars, their vast distance reducing their luminosity to a mere whisper. In the foreground a storm rages, lightning illuminating the clouds to a red and purple glow.
And above it, apparently attempting to connect the two, the brief flash of a shooting star: A bit of cosmic debris no bigger than a grain of sand, heated to luminescence by its tremendous speed as it rams through our air.
As an added bonus, on the right is the ruddy glow of Antares, a red supergiant star that marks the heart of Scorpius, the scorpion. One day that star will explode, and from its distance of only about 500 light years it will shine about as bright as the full Moon! But that may not happen for hundreds of thousands of years.
I love the sense of scale in this shot: The clouds a few kilometers away, the meteor a few hundred, Antares a few thousand trillion, and the merged stars of our galaxy deep in the background, a hundred thousand trillion kilometers further yet.
If thereâs one thing I love about astronomyâand there are far more, I assure youâitâs the sheer size of it. From here to eternity, indeed.
