The Heart Glowing hydrogen gas 7,500 lightyears away in Cassiopeia. 17+ hours of imagery from my backyard telescope! So excited about this one! :D

Hydrogen-Oxygen Second Stage - a late 60s proposal for increasing the payload of Delta M using an RL10 and cut down Thor tankage. Using an AJ10-118F because I didn't have a textured RL10 handy.

Why is there long red streak attached to this galaxy? The streak is made mostly of glowing hydrogen that has been systematically stripped away as the galaxy moved through the hot gas in a cluster of galaxies. The gas tail is about 200,000 light-years long https://t.co/lNoJRQ74iI

The large emission nebula dubbed IC 1805 looks, in whole, like a human heart. The nebula glows brightly in red light emitted by its most prominent element: hydrogen https://t.co/YlWWQD1w0o

One of my favourite Apollo facts. If the service module hydrogen tank was filled with ice and stored at 70 degrees F, it would take 8.5 years for the ice to melt. If a car tire leaked at these rates, it would take 30 million years to go flat.

Great tool from David Goodsell for the creation of protein structure illustrations in the typical style of the "PDB Molecule of the Month". Here is an example using the methanol dehydrogenase from M. extorquens. https://t.co/woZC79oMUq
