Imagine yourself in a boat on a great ocean, stretch the water to the right path, with the smallest of a land just beyond. It's a morning, just before the soil, and a submerged smoke is located on the coast. As the slider clicks on your early clock, you'll be able to. catch out of the corner of your lighthouse eye, rapidly shifting through the fog.

And – yes – that's it! Another lighter, closer lighthouse, the light is slightly stronger. As you write the competition there are more lighthouses that mark off the dangers of the eastern coast.

A new star has been made to light up the cosmetic clouds around this image from the ESO La Silla Theater in Chile. The caterpillars of dust are in the large clouds that surround the HD 97300 star to & # 39; divide its light, like a car destination to smoke, and Creating a reflection of IC 2631. If HD 97300 is currently in the scene, it's the dust that makes it so hard to mourn for it. steal extra sticks, potentially spectacular, stars in the future. Imsge: ESO

You know this coast, returning to the same port year after year. You know that all lighthouses are the same clarity, made up of the same industry and kept in good order over the years.

And so the time you play a small game. Give advice to your records, you know what distance it is; For each lighthouse, and how long the light has traveled to your eyes of salt. But the sun, clear and sad at night is clear, loosened and restrained with a continuous fog. You know how clear they are right and you can compare that color and what you can see, look through the lines and the foggy lines, to estimate how tightly it is. haul the coast.

It does not seem that you have anything to do better.

This is just the method used by recent regulators to measure the overall measurement of the star light in the universe – no doubt, of course, the mist and lighthouses and sailors salt.

Our cosmetic lighthouses are the most active galaxies, the most powerful engines in the acronym, where there is a case that is; flows into a blue and white reprinting spin and a & n; Heat up, pour out in surrender of radiation before swallowed up with the event. When they die, these aggressive motions of gas recite more energy than millions of diseases, and are able to pump the light all over it; globe.

When they get into the young cosmos, we look like lighthouses, but a lot of fun.

Between these lighthouses and all our telegopypanes material in the text. Most of the universe is empty, but the accumulated light from the generations of the stars that live and die from these long-standing, shining in cosmos in a little fog and a tuna of photons.

The radiation that comes from the far-reaching active galaxies is very high – no wonder, due to the powerful nature of the source. And since the light is high energy light throughout the globe, it will meet the & # 39; thin smoke. Interoperability with equity, random accident, accidental co-operation, high energy radiation and energy loss and dispersed.

By analyzing the light from more than 700 active galaxies, the team of rhetorologists can estimate the star lights that have been brought forward throughout the globe and over a significant period, from just after the first stars just 500 million years after & # 39; near today. Rough counting? 4 × 10 ^ 84 photons, which … many.

This estimate agrees with other calculations on this hidden light as it is called, but is buried in this latest sight and others are a tricky look: our life is a # 39 , dying.

By comparing the light from the different active galaxies placed at a different distance from us, The reels can count on the total amount of starlight lights that have ever been made, but also find the flow and flow of this star light through thousands of years of traditional history.

And the news is terrible that the lights are going out, one to one. As best we can tell, over a variety of ideas and estimates, our star-based globe is more than 9 billion years ago, when the cosmos was just a quarter of the age old, today.

The same reason still helps us. Certainly there is something to do with the cursor that is a n; we grow – galaxies get more apart from each other on their cell. average, which means fewer unions and fewer new products; flow to galaxies, where they can turn that gas into new stars. But why was the roof at that time, so far back? Why was the creation of stars that declined soon? No, maybe, why stars have been running extensively, despite their single-grand empire that fell?

Hard questions with easy answers. For now, at least, we are still in the smoke.
