This is seriously cool. One lens galaxy is amazing, but two! (Too bad that this is not steerable.) Underlying paper: https://arxiv.org/abs/2411.04177 https://a

- travisporter 2y agoCool! Was hoping to see a magnification amount like 100x etc
- hinkley 2y agoIt would be cool if we some day had special days of astronomy where every telescope is turned to galactic eclipses the way they once did for solar eclipses. The sky is huge and we are moving, so surely some would happen in our lifetimes?
- yreg 2y agoSurely any such eclipse lasts a long time. From the perspective of our lifetimes it is static.
- ben_w 2y agoSpace is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. It takes light, the fastest thing that can be, 100,000 years to cross the Milky Way. The Sagittarius Dwarf Spheroidal Galaxy is currently in the process of being consumed by the Milky Way and is expected to pass through it within the next 100 million years. So, unless you're even more optimistic about life extension technology than I am, not in our lifetimes, no.
- vlovich123 2y ago> It takes light, the fastest thing that can be, 100,000 years to cross the Milky Way. Relative to us. For the light itself it takes no time.
- ben_w 2y agoOur own frame of reference is the only one that matters, given the comment I'm replacing to.
- consp 2y agoIsn't the idea to use the sun as a lense already enough? The main problem being the focal point at 500+ au.
