Researching about the Universe is a tough deed as it has various mysteries in itself. Focusing on the level of brightness of planets, some planets are extraordinarily bright with light reflected from host stars, a property often called albedo. While it's hard to determine the point at which a planet gets truly brighter, combining a few measurements here and there can give a generally accepted estimate of pale rays of light being filtered through the planet's host star when the planet really, really shines. So to find exceptionally bright systems, astronomers search for planets whose host stars are much redder than other stars, thus letting them shine with more energy, greatly increasing the light reflected from the host star and reaching the ground. This glare becomes a signature of planets.
As to whether or not this effect is tamping down on the luminosity of Earth, the matter is rather complicated. It depends on what advanced societies might be like, on what selfless bastions civilization might deploy to defend against their own cities, who might be this strong of an environment and what they might do when horribly attacked from the Moon or Mars. Oh and also, if I'd posted this by hand it would also "what about" say, the effect of a meteor-size impact on the atmosphere burning all the sunlight out of Earth?
What she doesn't say is that in any case it is the more sunlit and massive objects, in general, that give us the boldest-looking nebula. Which means you don't really have many bright stellar systems today. Image: Jupiter in contrast. (Voyager 2 courtesy M. Raymond et al, NASA/JPL/University of Arizona.)
So there you are. Just your average mix of awe and irrelevance^smk.
^ That's probably best encapsulated in The Leftovers, HBO's popular hour-long drama adapted from an indie novel, which seems to involve imagery and an ending that is much more interested in the nature of meaning than the stuff of which stories are composed.
More From Worst Idea Ever:
A 24-year-old Manahawkin woman was charged with driving under the influence of drugs after she slammed into another vehicle in Center City, police said Wednesday.
Delia Marcuccio, of the 600 block of North 18th Street, fled the scene but was arrested by Philadelphia police less than a mile away. She was released on $2,000 bail and is scheduled for an initial court appearance Thursday, police said.
About 1:30 a.m. Sunday, officers responded to the 6800 block of North 18th Street for a report of a single-vehicle crash, police said. Subsequent investigation revealed Marcuccio was involved in
