Earth-Like Planet orbits Sun-Like Star

AI Thread Summary
NASA recently announced the discovery of Kepler-452b, an Earth-like planet orbiting a Sun-like star, based on spectral analysis of its light interactions. The discussion highlights the immense distances in space, comparing Kepler-452b's distance of approximately 1300 light years to Pluto's 4.5 light hours. A hypothetical journey to Kepler-452b, using the same travel rate as the New Horizons mission to Pluto, would take around 19 million years. This emphasizes the vastness of space and the challenges of interstellar travel. Understanding these distances is crucial for grasping the scale of our universe.

That, anyway, is the headline in today's news, regarding the interesting discovery announced by NASA overnight of the planet dubbed Kepler-452b.

As I understand it, the properties of the planet are inferred from spectral analysis of its effects on the light from the star which it orbits.

However my question is more - well - quotidian. Last week's astronomical news was the fly-by of Pluto (an amazing achievement, I hasten to add) by a craft that had taken nearly ten years to reach its destination. The signals were then taking about 4.5 hours to reach earth; in other words, the craft was 4.5 light-hours away.

If such a craft were to travel at the same rate to Kepler-452b, how long would it take to arrive?

The discovered planet is approximately 1300 light years away.
Pluto is 4.5 light hours away, and New Horizons took 7.5 years to get to it.
There are of course many variables which can be argued about, but very roughly that works at about 19 million years I think.

Right! That is the kind of ball-park figure that I thought it might be. It just helps to get an idea of the immense distances involved.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
