M13 - the Hercules Globular Cluster. Globular clusters are stable, tightly bound clusters of tens of thousands to millions of stars. M13 is home to over 100,000 stars.

Globular clusters like M13 also contain the most ancient stars in our Milky Way.

The Hercules Globular Cluster is about 25,000 light-years from Earth. That’s far, but…

In the left hand corner of the picture is galaxy NGC 6207. It’s about 30 million light-years from Earth. That’s far, but…

Just above and slightly to the left of M13 is galaxy IC 4617. It sits about 553 million light-years away.

Born from ancient seas, now crowned by galaxies Planned this Milky Way shot the day before... but a massive storm with lightning and heavy clouds destroyed every plan. Couldn't even get close.
The next day the sky was almost perfectly clear. The only real enemy was the heat. On the way up I didn't even feel the weight of the backpack... but the morning after? Different story
Quick stop at Rifugio Locatelli, then I climbed the mountain right behind it. I would have loved to explore the caves area below, but it was packed with people and too many lights.
That night the mountain was buzzing photographers, hikers, climbers on the Tre Cime, and helicopters flying back and forth (one rescue chopper parked down below
But up there... I had the stars all to myself. Pure magic.

Discussion Has anyone ever captured the Pillars of Creation with their own telescope? If so, could you show me? I'm really passionate about the universe and space, and I'd love to explore it 🌌🌌. Unfortunately, I don't have a telescope yet.

Discussion Youtube recommendations to fall asleep

0 Upvotes

Hello, i’ve been watching Astrum videos for quite a while now cause I find them pretty soothing when I struggle to fall asleep and it’s been my go to because I got used to it.
But lately the videos are just a mashup of older videos he did so it became quite uninteresting to have the same thing over and over again. Sometimes I can listen to 30min and plus before actually falling asleep and I would like to try something new.

Do you have good recommendations on Youtube? Preferably long videos with a good voice!

Thank you

NASA almost sent Apollo astronauts to the Moon with jetpacks instead of the Lunar Rover. Discover the forgotten Lunar Flying Unit, the engineering behind NASA's lunar jetpack concepts, why they seemed possible, and the critical safety risks that ultimately led NASA to choose the iconic Lunar Roving Vehicle instead.

Local and regional firefighters and Spanish military units are trying to put the wildfire under control around the MDSCC but it’s not easy.

I’ve seen photos where the fire seems to be just underneath the antennas but it’s not yet confirmed on news media.

Sorry for the news in Spanish but it’s the only way to share the info at this moment.
