WOW ! This is how some of the earliest stars in the univers look

Meanwhile in space: moon activity and satellites viewing satellite launches.

A COLD START
If we look through the telescope, we can look at the past. Light is moving fast, but there is still a lot of time required for illumination of sources that reach the universe to achieve our livelihood. We have seen super-heavy black holes from the beginning of the universe, only 800 million years after the Big Bang. But in a study published in Nature this week, researchers can see more - 180 million years
after the Big Bang - when the first star was formed.
"What happens during this period," said Alan Rogers, an astronomer at MIT's Haystack Observatory, in a press release, "is that some of the radiation from the very first stars is starting to see hydrogen, causing hydrogen to begin to start the background radiation. absorbing, so you begin to see it in silhouette, at certain radio frequencies, which is the first real signal that stars begin to form and begin
to influence the medium around them. "
The researchers think it is unlikely that we will soon be back in the history of the stars, but they will continue to look for other information about the childhood of the universe, including why the hydrogen gas seems colder than expected. Much colder. Another article in Nature suggests that this may be due to the presence of dark matter, a fascinating possibility that other researchers would like to
investigate. With all the other news this week in the world, chances are you do not have much space. But there was a whole universe of things going on. Here are a few other stories you may have missed:

WET AND WILD MONTH
There is a lot of moon news this week. We already know that there is water on the moon and some of them can be quite difficult to reach. A new study published in Nature Geoscience found that water can be wider than we thought, spread across geographical areas, but also concluded that the water can
be very immobile. Researchers are interested in a better understanding of the water reserves of the Moon, because water is a valuable resource for future expeditions - great for drinking, of course, but also for the destruction of oxygen (for breathing) and hydrogen (for the generation of rockets).
Water on the moon also tells us something about the development of our natural satellite. A paper published in Earth and Planetary Science Letters used models to mimic theories about how the moon might have formed. They discovered that having widespread water on the moon was still consistent with the leading hypothesis, namely that another planet-sized object collided with the early earth. The impact ensured that material flew into space, which eventually merged into our Moon.
