Last week was jam-packed with interesting news straight from the world of science. Today’s summary will include about a powerful glow emanating from a neighboring star, the first flight of an ingenious helicopter and the so-called tiny foot.
The New Horizons spacecraft has already come a long way. where is he?
NASA’s New Horizons probe is 50 astronomical units away from the sun, which means that the distance between this instrument and our star is 50 times greater than the distance between it and the Earth. One of the astronomical units represents a distance of 149.6 million kilometers, which makes it possible to calculate the exact distance between New Horizons and the central star of the Solar System about 7.5 billion kilometers.

A non-Sun star closest to Earth that generated a powerful glow. It turned out to be a solid track record
Proxima Centauri, in proportion to a rather unstable object, emits large amounts of radiation, releasing plasma and light scattered through space. Of course, this is not beneficial to the planets around this star, since such explosions sterilize them of potential life forms – unless they have developed resistance to radiation during evolution. But in their element are astronomers who recently captured the strongest glow ever documented inside Proxima Centauri.
Did you catch tyrannosaurs alone? The researchers startling results
Analysis of fossilized bones and surrounding rocks at the Grand Staircase-Escalante National Monument showed that the remains belonged to representatives of the species Tyrannosaurus rexWho died together at a similar time. The first assumptions about the alleged mass hunting of dinosaurs appeared in the early twentieth and twenty-first centuries, when twelve or so dinosaurs were found, whose remains were located inside a Canadian fossil site.
You wouldn’t guess why scientists put meteorites in the oven
Scientists often study their rocks to see what other planets are made of and whether they can contain life. These, which take the form of meteorites, fall from time to time to the surface of the Earth. Astronomers decided to crush, bake, and analyze portions of these cosmic rocks to discover the resulting gases. As part of further research, the team plans to use more efficient sensors.
Here’s Little Foot. Our distant ancestors inhabited the Earth 3.6 million years ago
Scientists analyzed fossil remains dating back 3.67 million years and found that its owner, called Little Foot, lived in the trees. The aforementioned creature was about 120 cm long and had long legs that were adapted to walking on. Taking into account the structure of the shoulder girdle, the scientists concluded that it was a kind of golden mean between the anatomy of humans and modern apes. This indicates that Little Foot was our distant common ancestor.

Creativity Helicopter made its first flight to Mars. This is a historic moment
The Creativity Helicopter made its historic flight on the surface of Mars. The spacecraft flew approximately 3 meters for about 40 seconds. The helicopter weighs less than two kilograms and could make four more flights in the coming weeks. Contrary to appearances, a journey on a planet other than Earth is a huge achievement. The gravity of the red planet is weaker than that of our planet, while the pressure is only 1% of the Earth’s gravity.
This guy put his head on a particle accelerator. What happened to it?
Accelerators accelerate charged particles to very high speeds, including in order to cause them to collide with other particles. Anatoly Bugorsky also had such a “collision” by chance and almost paid for it with his life. Absorption of 5 degrees of radiation usually results in death, while exposure to radiation of the world is in the range of 2000-3000 Gy. Over the next few days, his skin peeled off as the bar hit his head, creating a gap that extended from his face to the back of his head. However, Bugorsky’s story ended happily, and the guy lives to this day.
NASA has shown what the Lunar Gate will look like. look at the pictures
The Lunar Gate aims to be a space station orbiting the moon and serve as a launch site for missions heading towards or leaving the Silver Globe. The idea is for the ships to dock inside LG and then continue their journey in another vehicle. After the astronauts do what they planned, they will return to the station to pick up their ship and return it to Earth. NASA wants to launch the first Lunar Gate clips by 2024, although it is not known how much time will be needed to partially operate the station, let alone fully operational.
Scientists discovered from the books of Qumran Scrolls. Artificial intelligence helped
The Qumran Scrolls, also known as the Dead Sea Scrolls, were found in the late 1940’s. They were found by a shepherd looking for a lost goat and documents found in a cave. However, it was not certain who its author was or whether it was the work of one or many people. Researchers take a closer look at the new analysis Isaiah’s Great Scroll It harnessed artificial intelligence to work and capitalized on the benefits of statistics. Thus they concluded that the manuscript was written by at least two people.
Humans stop the evolution of species and lose, among other things, the Baltic Sea
Humans deliberately isolate certain species, for example for the purposes of reproduction, which is usually more efficient if all individuals are the same. Through selective breeding over several decades, organisms with predictable characteristics are obtained, which reduce costs and increase production profits. Unfortunately, this prevents long-term evolution of the species, as has been observed with Atlantic salmon in Sweden. Often representatives of this species escape into open waters, where they come into contact with wild individuals. As a result, its unfavorable traits from the point of view of survival begin to spread in nature, which reduces genetic diversity.
