NEW YORK (CNN) – The Japanese space probe released a ball into an asteroid, and Israel launched a spaceship on the moon, hoping to become the fourth country landing on its surface.
around Neptune, a tiny tyrannosaurus that changes the chronology of dinosaurs and an intriguing view of the habits of early humans. It can be really cool, so think of what Curiosity and InSight have to go through the next time you're complaining about the winter on Earth.
NASA also named another installation for Katherine Johnson, an incredible mathematician and "human calculator." Early missions, including John Glenn's friendship 7 and several missions of Apollo. In addition to the computer fund Katharine Johnson, there is currently a Catherine Johnson Independent Verification and Testing Center. This is suitable for the 1
And this is not even all that happened this week in the world of space and science.
This is what you
It is appropriate to start with the news of the launch of the Beresheet, an unmanned spacecraft, which took place on Thursday in Israel from a non-profit space corporation SpaceIL. He refers to the first words of the Bible in Hebrew: "At the beginning".
A private missionary mission began a seven-week journey before she tries to control the landing on the Moon. Expect cool pictures of the moon's surface. He is also going to conduct experiments on the magnetic field of the Moon. It is expected that it will land on April 11 after a few turns of the Earth before it will be a "horn" on the Moon, traveling about 4 million miles in the process. Enjoy the ride, Beresheet!
The Japanese space probe Hayabusa 2 shot a "bullet" in the Ryugu asteroid this week, and it's not just for a random target. The mission of Hayabusa 2 includes the collection of asteroid samples, which can be turned to Earth and studied.
The ball broke the material on the surface of the asteroid, and Hayabusa 2 was able to collect it after touching it on the night.
The asteroid has a gravel surface, not a dust that was expected. Samples will not be returned until Hayabusa completes its mission and does not say goodbye to the asteroid in December.
Meanwhile, Hayabusa 2 will try several more sample attempts. Thus, the asteroid and spacecraft have enough time to reconcile their differences – or even more antagonize each other – before leaving the probe at the end of the year.
Astronomers are always studying the sky, and sometimes they find things in a marvelous fashion by Marco Polo. Scientists from all over the world reported this week that hundreds of thousands of distant galaxies were discovered in their new radio exploration of the sky, whose signal now reaches us billions of light years.
But researchers could also see black holes, consider the evolution of clusters of galaxies and measure magnetic fields. Radio astronomy helps to identify what can not be found with optical light. And the supercomputer helped turn data into high-resolution images in just one year, while the usual computer could take centuries.
Another research team used the Hubble Space Telescope to find a tiny inner moon around Neptune, dubbed Hippocamp. Voyager 2 found six internal Neptune satellites when he drilled the past in 1989, but he missed this little boy. This is normal, Voyager 2. It's just about 21 miles in diameter; For comparison, Neptune has 30,599 miles in diameter.
Hippokam, now known as the smallest month of Neptune, named after the sea monster of Greek mythology, by which the tail of the fish is attached to the horse's body
But this is perhaps the remnant detached from Protheus, the largest and the most distant from the inner satellites of Neptune, which simply has a giant crater on it.
NASA's volunteer scientist finds the coldest, oldest white dwarf, and is surrounded by dust and dust rings.
A white dwarf is what's left after a sun-like star has died, and the Remnant is usually the size of the Earth. This peculiar white dwarf, LSPM J0207 + 3331, is located at a distance of 145 light years in the constellation Capricorn.
And this is 3 billion years, with a temperature of about 10 500 degrees Fahrenheit. First, it's much hotter, because white dwarfs cool down slowly when they age. Blown discs and rings were previously found only around white dwarfs that were much younger than J0207. – but this is a puzzle that astronomers will need to learn to understand.
And if this is not enough for you, remember that the burst event of the gravitational waves since August 2017? Or maybe you know it as GW170817. It was then that scientists around the world had witnessed the fact that two neutron stars encountered the first time, creating gravitational waves, a spike in gamma rays, and even elements such as gold.
Initially, they were not completely sure of the material that came out of this explosion. Now they say that the data show that the so-called jet of the material expands as fast as the speed of light, proceeding from the event and into interstellar space.
Look at this guy. To borrow a great comment from my editor, "he looks as if he needs to wear a cylinder." giant tyrannosaurus rex.
Moros was only about 3 to 4 feet tall, compared with T. rex, which may be 15 feet. But do not let you be fooled. This little boy was an excellent predator, easy and built for speed. In addition, he is translated as "the forerunner of death".
"With a lethal combination of bite strengths with bones, a stereoscopic vision, rapid growth and colossal size, the tyrant of the dinosaurs reigned unhindered for 15 million years, which led to the end of the Cretaceous extinction – but this was not always the case," said Lindsay Zanno, a lead author of a new study and a paleontologist at the State University of North Carolina. "When and how fast the Tyrannosaurs moved from the roll-up color to the King of the Prom, he was long frightened by paleontologists. The only way to attack this problem was to go there and find more data on these rare animals. "
mental image of a revenge of the Tyrannosaurus in a crown suit with a head or not.
Sorry for coming out of the prom immediately to a mass extinction – even if the Tyrannosaurus rex was the last gigantic predator that had a pleasant time by the end of 66 million years ago. So you probably heard that the asteroid fell to Earth 66 million years ago, and the mass extinction destroyed the dinosaurs. scientists have often wondered if there is an asteroid The reason for this is as if more hell was needed to drive out the greatest creatures that ever wandered through the earth.
This other hell belongs to volcanoes, in particular to the Dean's traps in India, exploded at about the same time and continued emitted for about a million years Two studies published this week suggest that the asteroid and volcanic activity are coupled with the fate of the dinosaurs, although they get differently

. The protein is similar to a large hunting of savannahs and other open fields.
Boy, were they wrong, according to a cave in Sri Lanka, full of burned and torn monkeys and squirrels. The contents of the cave indicate that people there lived 45 thousand years ago. And they were smart enough to stably hunt for their choices up to 4,000 years ago.
Proteins and monkeys live on trees. They would take a lot of effort to hunt and grab, especially with the help of strikes darts, scientists believe that early people were used. And squirrels and monkeys did not bring a lot of protein
But the first people could use monkey bones as a tool for hunting monkeys. And they did it, relying on all the tools for the bone monkey found in the cave.
In order to save the source of food from death, they studied the habits of monkeys and only killed adult prematurely. And the fact that they have done so long without affecting the population shows how intelligent our ancestors are.
