"How Far the Stars Are" is the next astrophysics composition by TRUNKS ART!

Boise, Idaho - December 28, 2019 - "How Far the Stars Are" (#2/12) - On a clear night, our naked eye can see Sirius, the brightest star at almost 9 light years away, and Deneb, the furthest star at 1,500 light years, and even Andromeda, our closest galaxy neighbor at a whopping 2.5 million light years.  And, with telescopes like the Hubble, distances are calculated into the billions of light years!

So, just how do they know how far the stars are?  Stellar Parallax (Friedrich Bessel, 1838) is a method that uses plain old trigonometry but is limited to only 400 light years.  Standard Candles (Henrietta Leavitt, 1908) extends that distance to the far reaches of the universe using Cephied Variables (super bright twinkling stars).  But you know what's more mind blowing than these inconceivable distances?  The stars we do see are no longer there and are mere glimpses into the cosmic past.  

Yep.  Mind blown.

New Physics Art Series by TRUNKS ART: "Why is the sky dark at night?"


Boise, Idaho - December 13, 2019 - "Why is the sky dark at night?" (#1/12) - What's interesting about this seemingly pedestrian question is that it took nearly 400 years and the minds of Albert Einstein and Edwin Hubble to unravel and answer.  With an infinite number of stars in the universe we should conceivably see the entire night sky filled and lit up by starlight - but we don't.  Instead, we see only the "observable universe" which includes stars whose starlight has had time to reach us.  So if you're thinking that we'll see more and more stars in the night sky as time passes - guess again.  Thanks to a universe that is expanding at an ever increasing rate, the starlight from those distant stars will NEVER reach us.  In fact, many of the stars, including whole galaxies will fade from view leaving only the stars in our own Milky Way galaxy to inspire and perplex the far future generations of hopeful and inquisitive stargazers.
