James Webb can't resolve Earth-size planets around Sun-like stars. Not just because of the contrast but also because of the diffraction limit. To do that you need a mirror of 20+ meters. But what if you increase the size in just one direction? You get the required resolution but keep the mirror relatively small and easy to transport. This is the idea behind the Rectangular Mirror Telescope.

Should we destroy asteroid 2024 YR4 instead of letting it hit the moon? Why Hycean worlds probably don't exist. Liquid water once flowed on asteroid Ryugu. Space bytes+ a supermassive black hole that is breaking the Eddington limit.

Can neutron stars create an equivalent of Type 1a supernovae? Can you land on Venus without a parachute? How do we know the shape of the Oort cloud? And in Q&A+, what's going on with 3I/ATLAS' weird tail situation?

Could we turn Earth into Jupiter by just adding more atmosphere? Can we train to communicate with aliens by talking to animals? How's YouTube destroying itself and it's getting really dangerous? And in Q&A+ will Vera Rubin find an asteroid on a collision course with Earth?
