How Far Can You See Into Space Without a Telescope?

The article explains that under ideal dark sky conditions, the average person can see stars up to magnitude 6, which includes stars up to about 8,000 light-years away, and even some galaxies like Andromeda at 2.5 million light-years. Notably, a gamma-ray burst was visible to the naked eye at a distance of 7.5 billion light-years. The Magellanic Clouds are the most distant objects visible without a telescope, at over 160,000 light-years away, highlighting our remarkable ability to observe cosmic phenomena with the naked eye.

Superman's Journey Time from Krypton to Earth

Astronomers have identified a potential star system, LHS 2520, that could be Krypton's location, which is about 41.9 light years from Earth. Given the limitations of current human space travel technology, it would take millions of years for a spacecraft to reach Krypton, but in the DC Universe, faster-than-light travel and Kryptonian technology could make the journey much shorter. The article explores the implications of these distances on Superman's age and origin story.

"Imagining Our Solar System in the Andromeda Galaxy"

Predicting the current appearance of the Andromeda Galaxy is impossible due to its distance of 2.5 million light years away, meaning we can only see it as it was 2.5 million years ago. If we could observe it now, it would likely appear similar, with minimal changes over such a timescale. Looking back at our own Milky Way from Andromeda, our Solar System would be indiscernible among the billions of stars in one of its spiral arms, while the familiar constellations from Earth would become distorted and unrecognizable.
