Reply to Everyone talks about how huge Andromeda will look in the sky billions of years from now. I present you what the Milky Way *currently* looks like in the skies of our neighbor, the Large Magellanic Cloud. We appear absolutely huge in their skies! [Simulated view] by lampiaio

Actually you wouldn't be able to see it because there is not enough photons reaching your eye. If you kept a camera film exposed over several hours you would see the image of the galaxy. It's a sad fact that we will never see a galaxy with our eyes even if Andromeda was almost on top of us.

Reply to This is what 7 minutes of exposure time looks like on a dark, moonless night at Zabriskie Point, Death Valley (USA)! by peeweekid

Wow! I was stationed at the National Training Center (bordering death valley) for 5 years and though I was always in awe of the way the sky looked at nights out there, it looked even more amazing with night vision (light amplification PVS-7B typically) goggles on. Halle-Boppe comet was super bright.

But I had no idea it could look so amazing. Thanks for this!

Reply to comment by KINGMARKOXIV in Latest video of the Ingenuity Mars Helicopter kicking up dust and taking off for Flight #47. Ingenuity is well beyond its warranty at this point. The video was captured by the Mastcam-Z imager aboard NASA’s Perseverance rover on March 9, 2023. by ICumCoffee

I don’t think they would have sent this technolgoy demosntration if they thought flight on Mars was a dead end lol. Despite the air being less than 1/50 the density of air on Earth Mars has lower gravity and heavier air molecules at least helping to partially offset the disadvantage of the thin air. Aerial surveillance is a powerful tool for Mars exploration and could be used to explore large regions on the surface and to sample the atmosphere.
