Sunspots registry – Program run since 1826

Sunspots registry – The longest regular scientific research in the world is the record of the number of spots on the Sun created since 1826.
The research program was initiated by the German amateur astronomer Samuel Heinrich Schwabe. He watched the Sun regularly for 17 years because he wanted to observe a planet previously unknown to science called the Volcano.
Moving against the backdrop of the solar disk. Of course, he found nothing – only Mercury and Venus are between Earth and the Sun. Known since antiquity – but his observations have determined that the activity of our nearest star changes regularly.
Schwabe’s achievements inspired Rudolf Wolf, head of the Bern observatory. Which from 1848 continued to record spots and collected historical data on this subject. Dating back to the early 17th century

Spot counting system developed by Wolf.

Accepted astronomers around the world. Almost 100 observatories are currently observing this phenomenon. Both professionals and amateurs.

Homosexual ibises – Result of poisoning

Homosexual ibises – Homosexuality can sometimes even be the result of poisoning say ornithologists from the University of Florida. This is the case of white ibises. If their diet is mercury, it causes endocrine disruption.

We thought that the toxic substance reduces the number of chicks hatched from eggs. It turned out, however, that changes the sexual orientation of birds.

said prof. Peter Frederick, who led the study. In his opinion, this can also apply to other species, reducing their chances of survival.

Falling planet – Phenomenon of extrasolar planet

Falling planet – The phenomenon of an extrasolar planet falling to its parent star. Observed by Dr. Gracjan Maciejewski of the Center for Astronomy, of the Nicolaus Copernicus University, along with guided their international research team. As for the planet WASP-12b, discovered in 2008. Planet is among the gas giants – planets similar to Jupiter or Saturn. There is, however, surprisingly close to its parent star, because within 3.4 million km (17 times closer than Mercury from the Sun). This causes the planet high temperatures, of the order of 2000 °C. Calculations show that the planet ultimately fall on the star for about one million years. It is a very short time compared with the estimated at about 2 billion years older tested planetary system. For closer orbits are responsible tides, which inspires the planet on its parent star.
