Found the largest extinct creature on Earth
An international group of paleontologists discovered the jaws of the bones of an ancient marine reptile, whose age reaches 205 million years. The fragment of the skeleton belongs to a giant ichthyosaurus 26 meters long, which is comparable to the average size of a blue whale. Remains of animals were found in 2016 on the beach in the village of Lilstock in the British county of Somerset. Specialists identified the specimen as a bone of the lower jaw, called suprangular. It was compared to the fragments of the jaw of other ichthyosaurs, including Shonisaurus sikanniensis, which belongs to the Shasta-Zaurian family and reaches 21 meters in length. The results of the comparison showed that the new species of ichthyosaurs should be 25 percent larger. He lived during the late Triassic period (Mesozoic era), when dinosaurs already lived on Earth. Similar remnants of scientists found in the XIX century. So, in 1850, a large bone was described with an age of 208000000 years, but the researchers believe that it belonged to stegosaurs or sauropods. Although these fragments were lost, scientists suggest that they were part of a much larger animal than the ichthyosaurus of Lilstock.
In Russia, ground tests of the manipulator arm for the ISS have been completed
The ground testing of the Russian manipulator arm, which will be installed on the surface of the International Space Station, is completed. Now the ISS uses the large Canadian cargo arm manipulator Canadarm and the flexible manipulator Dexter included in its composition. The European "arm" of the ERA is preparing to be sent into space. "The fabrication of the flight sample of the product - the specialized manipulation system" Zahvat-E "is being completed. The first prototype of the system has already successfully passed the ground tests, "Dalyaev said. Within the next stage it is planned to test the "hand" in the conditions of the open space. To this end, the developers are waiting for the launch of the new Russian Multifunctional laboratory module "Science" to the ISS, on the surface of which it is planned to install a Russian manipulator arm. According to the current plans of Roskosmos, the module is planned to be put into orbit in December 2018. After his arrival at the station on the cargo ship "Progress" a hand-manipulator will be delivered, and astronauts will install it on the outer surface of the ISS.
Dron found giant footprints of dinosaurs
Paw prints of extinct creatures were found on the Isle of Skye in Scotland. It should be noted that in this area very often traces of prehistoric creatures are found. Scientists believe that earlier it was very hot here and dinosaurs felt very comfortable on this terriotory. So it or not, it is only to be guessed, but an undeniable fact is that recently here were found as many as 50 new tracks, the age of which, according to researchers, more than 170 million years!
Here, There and Everywhere: Across the Universe with the Beatles
The Beatles are one of the greatest cultural phenomena to come from the 20th Century, yet many people are unaware of their impact on science. In 'Here, There and Everywhere', inspired by the book 'La scienza dei Beatles' ('The science of the Beatles'), Viviana Ambrosi shows how the Fab Four can bring the study of celestial objects and the exploration of the universe closer to a large public audience. This is set out in a presentation on 3rd April at the European Week of Astronomy and Space Science in Liverpool. The Beatles formed at the start of the space race, and have always inspired scientists, whether they knew it or not. The Beatles' record company (EMI) used money from the sale of the White Album to fund scientific research. Some of which went towards Godfrey Hounsfield's research into X-rays, which led to the invention of the CT scanner, for which he shared a Nobel Prize.
Astronomers have recorded mysterious cosmic outbreaks
Scientists from the University of Southampton (UK) recorded in the sky more than 70 bright and short-term outbreaks of unknown origin. At the same time, according to Phys.org, in the data, which were obtained during the Dark Energy Survey Supernova Program (DES-SN), intended for the study of distant galaxies, astronomers have identified optical transients - objects with variable speed. The fixed flares were compared with the types of explosions of stars by the level of their brightness, it was noted that they lasted for less time than supernovae, reached a temperature of 10-30 thousand degrees Celsius and a diameter 100 times greater than the distance from the Sun to the Earth, which reaches about 150 million km. DES-SN employs the telescope of the Inter-American Observatory Cerro Tololo in Chile.
Airbus delivers new life support system for the ISS
Airbus has delivered the ACLS (Advanced Closed Loop System), an advanced life support system to purify air and produce oxygen for the International Space Station (ISS). The system also produces water, more or less as a by-product of the technology. ACLS was developed by Airbus for the European Space Agency (ESA) and is set to be used as a technology demonstrator on the ISS from summer 2018. The ACLS extracts a portion of the carbon dioxide in the cabin atmosphere and, using hydrogen obtained from splitting water molecules, converts it to methane and water in what is known as the Sabatier process. Oxygen is then produced from this water using electrolysis. This increases overall system efficiency and reduces the need for supplies from Earth.
Laboratory for the study of dark matter is preparing to receive a new detector
Researchers at the University of Houston, USA, are helping to develop technology that can help solve one of the greatest mysteries of our time - the mystery of dark matter. Scientists believe that dark matter accounts for 85 percent of the matter of the universe, but no one knows exactly what it is. Physicists from the College of Natural Sciences and Mathematics at the University of Houston work under a program called DarkSide, aimed at finding dark matter in the form of weakly interacting massive particles, or WIMPs. In theory, collisions of VIMPs with the nuclei of atoms of normal matter should be accompanied by a small, low-energy "rebound" of the latter. Watching these "bounces", scientists can register the presence of VIMPs. Currently, for these purposes, the team uses a detector called DarkSide-50 (DS-50), located underground in the laboratory Gran Sasso National Laboratory, Italy.
In the ice of Antarctica discovered an ancient monster
20 meters in length, 3 meters in height - it was a real giant of the ancient world! Similar creatures lived about 70 million years ago and have never before met on the territory of Antarctica. Paleontologists believe that the bones belong to a giant titanosaurus, which until recently was believed to have lived anywhere, but not on the icy continent. The remains of titanosaurus were found in Europe, Africa, Asia and South America - it seems that the huge dinosaur had time to settle all over the planet. The head of the research team, Ignacio Cerda, made a bold assumption: the titanosaurs came to Antarctica by the isthmus that existed in antiquity, connecting the continent with South America. Surprisingly, scientists do not fully understand how the titanosaur managed to "conquer" such a vast territory.
NASA conducts the final testing of the James Webb telescope before being sent to space
On March 8, engineers removed the combined optical and scientific instruments of the James Webb (NASA) space telescope from its high bay container at Northrop Grumman Airport in Redondo Beach, California, and reported on the next step in the integration and testing of the observatory. Northrop is the final stage of the Webb trip, before it travels to its launch pad in Kourou, French Guiana. The engineers will conduct final testing at the facility to provide the last stage of the observatory's preparation for space. Combined optical and scientific technology Webb, the scientific payload, is half of the observatory, including the 6.5-meter golden primary mirror Webb. The scientific payload recently arrived in Northrop after testing at NASA's Johnson Space Center in Houston. An integrated spacecraft and sun visor - the other half of the observatory, which is in the final assembly in Northrop, was subject to its own launch environment tests.
SpaceX launched its heaviest satellite into space
The world famous company of the American businessman Ilona Mask SpaceX launched into space the 50th rocket Falcon 9 with its heaviest satellite Hispasat 30W-6. The launch took place from the cosmodrome at Cape Canaveral. The broadcast of the launch of the jubilee rocket was published on YouTube. The rocket put into orbit the Spanish telecommunications satellite Hispasat 30W-6, intended for transmission of television signal and video signals. The satellite should also provide broadband Internet access in North America, South America, Europe and Africa. Jubilee, 50th launch Falcon 9 put into orbit Hispasat 30W-6 with a mass of 6092 kg. This is the largest geostationary satellite that SpaceX launched in its history.
The Soyuz-2.1A rocket was launched from the Baikonur cosmodrome
The Soyuz-2.1a rocket with the Progress-MS-08 cargo vehicle started from the Baikonur cosmodrome, the correspondent reports from the Mission Control Center (MCC), where the launch is broadcast. The rocket was planned to be launched on February 11 and during the flight of the spacecraft to the ISS for the first time in history to work out a new shortened two-turn scheme of rapprochement and docking with the station for 3.5 hours. However, at the start came a command to automatically turn off the engines, and the launch was postponed to the reserve date - February 13. Now the ship will reach the station only after two days - at 13.45 Moscow time on February 15. A launch window with ballistic conditions allowing to send and dock the ship to the ISS using the ultrashort scheme has already been missed. According to the source in the rocket and space industry, the cancellation of the launch could result in the failure of the signal through the connector to the bortcomputer or the computer itself. The bortcomputer unit, at the same time, was replaced before launch.
In Rio de Janeiro started the world famous carnival
In Brazilian Rio de Janeiro solemnly opened the world-famous traditional carnival. The mayor of Rio Marcelo Crivelli handed the key to the city to the king of the carnival, which marked his beginning, reports DW. The carnival will last nine days. It is expected that 6.5 million people, including 1.5 million tourists, will take part in it. Carnival takes place in a time that is difficult for Rio. In the past year, due to lack of funds in the city treasury, about 80,000 workers were dismissed. The city also cut aid to the samba schools.
The most disappointing crypto currency is named
One of the crypto-currency networks Ripple - XRP can claim the title of the biggest disappointment for investors. This is written by CoinDesk. In January, its price rose to a record-almost to $ 3.8, then its rate began to fall. By February 4, XPR was worth $ 0.86 (minus 80 percent to the historical maximum). CoinDesk also notes that the Ripple rate in January grew, including on rumors about the addition of an asset to the Coinbase platform. The site, however, has not yet included XRP in the auction. This, like the falling market indicators, "hangs heavily" on the XRP, also noted in the material. According to Coinmarketcap on February 4, the capitalization of XRP amounted to 34 billion dollars, at the peak of the price of crypto currency, this figure reached 138 billion dollars. In August 2017, XRP replaced Bitcoin Cash from the third place in terms of capitalization.
Triumph of Ilon Mask. Falcon Heavy successfully launched, lateral accelerators returned to the ground, and the personal vehicle of the chapter SpaceX began to move to the belt of asteroids
On February 6, SpaceX made a successful launch of the Falcon Heavy (FH) rocket, the heaviest since Saturn-5. Specialists SpaceX managed to return the lateral accelerators of the rocket, but the central unit on the platform Of Of course I Still Love You in the Atlantic Ocean could not be planted, however, Ilon Mask himself called the launch of FH impeccable. "The launch was great, but the central segment, obviously, did not land on the platform," Mask portal news about high technology Engadget. "In this regard, we are conducting a check. Previously, we can say that there was run out of fuel, which was intended to slow down the decline of this segment, "he added. On board Falcon Heavy was an electric vehicle Tesla Roadster with a dummy in the spacesuit inside. Separation of the capsule with the car was also successful. As Ilon Mask reports in his tweet, Tesla Roadster left the field of gravity and began moving toward the asteroid belt in the heliocentric orbit.
Star winds behave "in an unusual way"
The European Space Agency's XMM-Newton Space Observatory has discovered surprising changes in the powerful gas flows emitted by two massive stars, and these changes indicate that the colliding stellar winds behave differently than expected. Massive stars - stars whose sizes are several times larger than the Sun - show high activity throughout the life cycle, rapidly burning their thermonuclear fuel and throwing huge amounts of material into the surrounding space during their short but bright stellar life. When the streams of such particles, emitted by different stars collide, the gas warms up to temperatures of the order of several million degrees Celsius and brightly glows in the x-ray range. In the new study, scientists observed a collision of stellar winds emitted by a double star system called HD 5980. This system consists of two giant stars weighing about 60 solar masses, separated by a distance of only 100 million kilometers - that is, closer to each other than the Earth to the sun.
In Syria shot down the Russian Su-25
The moment the missile hit the Russian Su-25 attack aircraft of the Russian Civil Code in Syria was on video. The plane was shot down by militants in the area near the village of Maceran in the province of Idlib. This area is under the control of the terrorist group "Dzhebhat an Nusra" (banned in Russia). The pilot catapulted and died in battle with terrorists. The footage shows how the terrorists shoot from an anti-aircraft gun to shoot down an airplane, then the video shows how a missile from a MANPADS gets into it. Video posted by the group "Free army Idliba." The Ministry of Defense of Russia stated that a group strike with precision-guided weapons was inflicted on the area from which the aircraft was fired. According to radio intercepts, as a result of the attack more than 30 militants were killed.
Russian astronauts have broken the record of being in open space
Delayed because of the complicated installation on the outer surface of the ISS, Alexander Misurkin and Anton Shkaplerov unwittingly broke the record for working in open space for six minutes, a correspondent from the Moscow-based Flight Control Center reports. The previous superiority to the time spent on the outer surface of the station among Russian cosmonauts belonged to Oleg Kotov and Sergei Ryazansky: in December 2013 they worked outside the ISS for 8 hours and 7 minutes.
Long March 2D launches Zhangheng-1 Earthquake investigator
A Long March 2D has conducted the sixth Chinese launch of 2018, with the lofting of the Zhangheng-1 spacecraft, a new research satellite for the observation of ionospheric precursors of earthquakes. The launch took place at 07:51 UTC on Friday from the 94 Launch Platform at the LC43 Launch Complex from the Jiuquan Satellite Launch Center (JSLC). An additional six small satellites rode along with the primary payload. The Zhangheng-1 (ZH-1) – also known as China Seismo-Electromagnetic Satellite (CSES) – was developed by the Chinese Academy of Space Technology (CAST) and is based on the CAST2000 bus. The satellite will be operated by China National Space Administration (CNSA) together with the China Earthquake Administration and the China National Space Administration in cooperation with the Italian Space Agency (ASI). ZH-1 carries six instruments to measure the electromagnetic effects of earthquakes above 6 magnitude in China and quakes above magnitude seven all over the world. On board the satellite is the High-Energy Particle Detector (HEPD) to detects protons and electrons, measuring the flow of protons and electrons in short-term disturbances in the radiation belt whether caused by terrestrial, solar or anthropic phenomena; the Search-coil magnetometer (SCM) that will measure fluctuations in the magnetic field of the ionosphere and the Electric Field Detector (EFD) to measure the variation of the ionosphere electric field due to disturbances from solar, seismic and anthropic phenomena.
From the cosmodrome "Vostochny" the third missile launch was carried out
From the Vostochny cosmodrome, the Soyuz-2.1a rocket was launched with eleven satellites on board. Among them there are two devices for remote sensing of the Earth "Kanopus-V" No. 3 and 4, as well as nine foreign vehicles. This launch was the third for the new Russian cosmodrome, and he went strictly according to plan, without any emergency situations, successfully removing the cargo to the calculated orbits. The launch of the missile took place at 05:07:18 Moscow time. Immediately after detachment from the launch pad, the missile completed a turn to take the necessary azimuth for launch into the polar orbit. After about an hour, the Fregat upper stage brought a useful load to the calculated orbits. The spacecraft division passed regular at 6:06 Moscow time, Roskosmos reports. The next launch of the Russian rocket from Vostochny is scheduled for February 11. In the course of this mission the cargo vehicle Progress MS-08 will deliver fuel, products and other valuable cargo to the ISS. In all, four launches are planned for the first quarter of 2018.
In Japan, hackers committed the largest theft of crypto currency
At one of the largest exchanges of digital currencies in Coincheck in Japan, after a hacker attack, the NEM crypto currency lost in value at about $ 534 million. The hacker attack occurred on Friday. On the Coincheck exchange, they learned about it only after eight and a half hours. Coincheck temporarily stopped depositing deposits and withdrawals for all crypto currency except for bitcoins. The exchange estimated its losses in the less known NEM crypto currency. It is noted that Coincheck's stolen money was kept in a "hot purse" that is connected to the Internet and is online. "Hot purse", unlike the "cold wallet" keeps the money offline. If the theft from Coincheck is confirmed, it will be the largest in history with the attraction of digital currency. The executive director of the exchange, Yusuke Otsuka, reported the kidnapping of 523 million in the NEM crypto currency.
