OMG congrats! How exciting! I can't wait to see your photos! I've tried with my SLR and uh it has NOT gone well lol.

I did it.

After a year of talking I finally bit the bullet and got a DSLR camera (Nikon D5300) for astrophotography. Will be using it at the observatory (16″ Cassegrain) as well as during hikes for sweeping vistas under the Milky Way. Very excited to explore astrophotography as a hobby and can’t wait to start uploading pictures

Everyone knows that, in space, no one can hear you scream. Sound is a wave that requires a medium to travel through, and if space is empty, there’s no medium to carry that sound. Except, as Mike from The Point Studios explains, empty is a relative term. Space is full of dust and gas and plasma, just not as full of that matter as we’re used to. Thus, the question of whether sound can travel through space turns into a matter of scale. If the scale–the wavelength–of a sound is much larger than the distance between molecules, then the sound can propagate. So there CAN be sound in space – it just has to have a very long wavelength and, thus, a very low frequency. Check out the video for the full story! (Video credit: The Point Studios)

Moral of the story:

Don’t fuck with the scientists and park rangers.

They largely consider themselves above politics.

The Republicans have awakened a sleeping giant.

Scientists invented fabric that makes electricity from motion and sunlight. To create the fabric, researchers at Georgia Tech wove together solar cell fibers with materials that generate power from movement. It could be used in “tents, curtains, or wearable garments,” meaning we’d virtually never be without power. Source
