Galaxies

Astronomers fill them in: White spots in the Milky Way

Gaia's observations of dwarf galaxies, planetless clusters and star streams make us aware of the amount of dark matter in the system. And they suggest that the Milky Way steals stars from passing galaxies. ## Family portrait reveals structure of Melkweg The Melkweg can be divided into three main elements: a thin and a thick disc and a spherical cloud, the halo.
Black holes

Gigantic black hole is possibly the toughest ever

American researchers from the University of Texas were very surprised when they investigated the small galaxy NGC 1277. The galaxy turned out to contain an extremely large black hole, with a mass of 17 billion times that of the sun. This makes the new black hole one of the largest ever discovered - possibly only one previously registered black hole is even larger.
Stars

Summer sun provides luminous clouds at night

A thin ice crystal carpet ripples along the sky at 80-90 kilometers, ten times as high as normal clouds. The distant ice clouds are on the border between two layers high in the atmosphere. They can be seen because the sun is never more than 10 to 15 degrees below the horizon around midsummer night.

Chlorine: from salt to poison gas

Name: Chlorine - after the Greek word 'chloros' (yellow-green) Atomic number: 17 Chemical symbol: Cl Chlorine is a yellow-green, strong-smelling gas. It is toxic to living organisms and was used as a poison gas in the First World War. Chlorine is very reactive, which means that it is very easy to form compounds with other substances.

Where does chalk come from?

In Northern Europe, chalk originated 70 to 100 million years back in chalk time from algae with limescale. Dead algae sank to the seabed, where there was so little clay and sand that almost pure chalk deposits could arise. Algae with limescale deposits settled on the seabed in chalk layers 70-100 million years ago.

Taurids illuminate the night sky

In the early morning hours, lie on your back in a place with not too much light - and the show will begin. It is the time of some of the most beautiful shooting stars of the entire year. The Tauriden meteor shower, which hits the earth in the first half of November, contains the remains of a comet that astronomers estimate 20.

Solar cell implant gives pacemaker power

The battery of a pacemaker has a limited lifespan and must be replaced with a minor operation after five or ten years. This is no longer necessary in the future. In a 32-participant trial, Swiss researchers tested whether a pacemaker can be powered by solar cells - and that is possible.

Young women have more sex

Most people have fewer sex partners during their lifetime than you might think. Half of all men have slept with only six different women, for half the women the figure is four. Men have twice as many sex partners. The other half is a lot less reluctant, because one in three men and one in five women has had at least 10 sex partners.

Old tooth shows: Neanderthals were taking painkillers

Neanderthals treated inflammation and pain with natural medicines. An international research team draws this conclusion in the scientific journal Nature after studying a 50,000-year-old fossilized jaw from northern Spain. Neanderthal cure toothache In a tooth, scientists found plaque, a bacterial layer that can lead to inflammation and cavities in the teeth.

About Science in the Picture

WE ARE OBLIGED TO OUR NAME In 1984, Science in the Picture came to the world with one central thought: no subject is too difficult to be exciting and interesting for the curious layman. That thought is still the foundation of our work. Knowledge and insight can indeed be conveyed in an entertaining and interesting way without it being at the expense of the facts and credibility.

Women can multitask better thanks to hormones

So. Women really can do several things at the same time than men. This appears from a new study from Switzerland, and the researchers also think they know why. According to them, the explanation lies in the female sex hormone estrogen, which probably makes it easier for women to use a brain area for several things at the same time.

Damaged nerves recovered super fast

If nerves are damaged in an accident, it can lead to paralysis or reduced sensitivity. If all goes well, a broken nerve recovers itself very slowly, or a surgeon can intervene. But in both cases, a nerve does not often regain its full functionality. Researchers from Texas have now developed a new method.

New accelerator must reconstruct big bang on earth

A bundle of protons awaits a cruel death. Researchers are pumping more and more energy into the beam with radio waves, which shoots through the narrow tube at almost the speed of light. In another tube - a few centimeters away - an identical bundle swings the other way. When the beams pass through large detectors, the physicists cause them to collide head-on with a force that no other machine on earth can deliver.

Does space offer us a future?

If we ever want to take over the solar system, space travel without people is unthinkable. But many scientists prefer that colonization takes place via robots. In 1989 the astronomer Harry Shipman devised a diagram with four scenarios for the future of space travel. According to him, that future is determined by the answer to two questions: 1) Can people live in space?

Many people have the throat tonsils removed because they are inflamed and swollen. But the tonsils are part of your immune system and catch viruses and bacteria before they enter the body through your mouth and make you sick.
