a couple of weeks worth of sketches lol
It doesn’t, though. Sometimes it only appears during the day, and other times it doesn’t show up at all. It needs the occasional downtime, but still you always know that it’s all right, it’s not gone forever, and you know exactly when it’ll be back again.
Five tornadoes’ worth of relieved sighs about the gunnerkrigg update
Seriously though Tom you have no idea how grateful I am that you don’t appear to be pulling the ol’ love triangle or, even worse, a “tragically struggling to overcome your gross homophobia for your queer best friend” arc
a lovely portal we found in tipperary
Zeta Ophiuchus, a massive star plowing through the gas and dust floating in space. Zeta Oph is a bruiser, with 20 times the Sun’s mass. It’s an incredibly luminous star, blasting out light at a rate 80,000 times higher than the Sun! Even at its distance of 400 light years or so, it should be one of the brightest stars in the sky … yet it actually appears relatively dim to the eye.
That’s because it’s sitting in a dust cloud, dense opaque material that absorbs the light from the mighty star and diminishes it. However, infrared light can penetrate the murk, allowing us to peer into the cloud and see what’s going on.
Zeta Oph is blasting out a fierce wind of subatomic particles (think of it as a super-solar wind) that expands around the star. Not only that, but the star itself is moving rapidly through the dust at a speed of about 25 kilometers per second (15 miles per second), so it’s violently compressing the material ahead of it. This creates that wave structure, which is similar to the wave off the bow of a boat, though more like the supersonic shock wave generated as a fighter jet screams through the air.
That curving wave is roughly four light years long: That’s 40 trillion kilometers!
