A study on the extra chromosomes titled "Detection and characterization of male sex chromosome abnormalities in the UK Biobank study" has been published in the journal Genetics in Medicine.

Data from over 207,000 men included in the UK Biobank has revealed that an extra sex chromosome, either an X or Y, may be prevalent in as many as 1 in 500 men. Typically, men are born with one X chromosome and one Y chromosome, however, in the dataset, were 213 men with an extra X chromosome, resulting in the XXY genotype, and 143 men with an extra Y chromosome, resulting in the XYY genotype.

Also referred to as 47,XXY and 47,XYY, the genotypes are called Klinefelter syndrome and Jacobs syndrome, respectively. Only 23% of those with Klinefelter syndrome had a known diagnosis, while only 0.7% of those with Jacobs syndrome were diagnosed. However, the latter has much more subtle characteristics that could contribute to a lower diagnosis rate.

Satellites from Maxar Technologies spotted preparations for rocket launches in Iran on Tuesday, June 14th.

The launch preparations are underway at the Imam Khomeini Spaceport for the Islamic Republic of Iran's new Zuljanah three-stage rocket for carrying satellites to orbit. The rocket is slated to be launched two more times after a previous launch at the same site where numerous failed attempts to launch satellites to orbit have occurred.

Satellite imagery captured a rocket on a transporter at the site, and later that day, a rocket was lifted onto the launch tower. Reporters questioned Ned Price, the spokesperson United States Department of State, about the launch preparations, who said, "Iran has consistently chosen to escalate tensions. It is Iran that has consistently chosen to take provocative actions."

Chinese researchers have published a new study in Nature Communications that confirms a major Moon discovery.

According to the researchers, China's Chang'e 5 lander has collected lunar rocks and confirmed via onboard analysis with its instruments that the rock samples contain water. Notably, Chinese researchers were able to estimate the amount of water molecules within some types of moon rocks - 120 parts per million and 180 parts per million (ppm) in other rocks.

The rocks were then studied by a team of researchers from the Chinese Academy of Sciences on Earth and found that the mineral apatite was 179 ppm, which was close to the earlier estimates from Chang-e 5. For quite some time, astronomers and researchers have suspected that lunar soil contains some degree of water molecules, but now we have a much better idea of the specific amount of water contained in some soil samples.

A group of astronomers have discovered a new multiplanet system that resides within our galactic neighborhood and maybe the closest known multiplanet system to Earth.

The astronomers, some of which are from MIT, initially used NASA's Transiting Exoplanet Survey Satellite (TESS) to discover the multiplanet system, which contains a small and cool M-dwarf star now named HD 260655. Additionally, the researchers found two terrestrial Earth-sized planets, which are believed to be rock worlds that have relatively tight orbits around HD 260655.

Due to the orbits of both of the rocky planets being relatively tight, the researchers believe that it's likely the Earth-sized planets aren't habitable as the planets would be exposed to the extreme temperatures of their local star. Despite the planets likely not being suitable for life, astronomers and researchers are still excited about the discovery as the planets are prime prospects for atmospheric study.

NASA's Perseverance rover is currently scouring the surface of the Red Planet looking for past signs of ancient life that may have inhabited the planet long ago.

Throughout its adventures, Perseverance has encountered many things that are both interesting and unexpected, and now NASA researchers can add another event to their "unexpected" list as Perseverance has located a piece of trash. Taking to Perseverance's official Twitter account, NASA explains that the rover discovered the trash jammed in a jagged rock and was later able to identify that the trash is a thermal blanket that was used to protect the rover from Mars' harsh atmosphere as it descended to the surface.

The Twitter account states that "it's a surprise finding this here" as the descent stage crashed approximately 1.24 miles away from the location of the thermal blanket. Questions have now been put forth as to whether the thermal material landed in this location or was blown there by martian wind. Now that Perseverance and NASA's team have enjoyed discovering some long-lost landing equipment, the rover will be directed to get back to its main task - exploring the Jezero Crater.

An image of a mysterious creature has recently gone viral, causing thousands of individuals to speculate online what species it could be.

The image comes from the City of Amarillo Twitter account that shared a screenshot from security camera footage taken at the Amarillo Zoo. The Twitter account explains that in the early hours of May 21, 2022, a mysterious creature was caught on film at approximately 1:25 AM. The Twitter account speculates that the creature could possibly be a person with a strange hat on or a "chupacabra," which is a legendary creature in folklore that feeds on livestock by drinking their blood.

The City of Amarillo described the creature as an "Unidentified Amarillo Object", and palmed the question off to the public to try and find out what it could be. As you can probably imagine, many people were happy to provide theories, some rational and possible, and some just claimed that the image was doctored and fake.

Potentially artificial signals were detected by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China.

Global Times, the self-described "China state-affiliated media" has reported that researchers from the Beijing Normal University have detected several signals using China's FAST. The signals are suspected to be from extraterrestrial civilizations," though the researchers are exploring further to confirm the findings.

FAST is the world's largest filled-aperture radio telescope, and has been used since 2020 to search for extraterrestrial intelligence (SETI). According to a Chinese source translated by Andrew Jones on Twitter, a self-described "journalist tracking China's space program," several candidate signals of "possible technological traces and extraterrestrial civilizations" have been found using FAST, referred to as the "Chinese Sky Eye."

The Federal Aviation Administration has finally completed its environmental review of SpaceX's Starship.

The Final Programmatic Environmental Assessment (PEA) is now available online, with the FAA concluding that SpaceX's plans for Starship and Starbase will "not result in significant environmental consequences." However, 75 actions are necessary before Starship will be able to launch. Following the conclusion of the assessment, SpaceX tweeted out, "One step closer to the first orbital flight test of Starship."

Following the news, Twitter users have queried Elon Musk when an orbital flight test of Starship might occur, after it was initially planned for late last year but delayed while awaiting the completion of the FAA's assessment. Musk responded by saying that Starship will be "ready to fly next month," indicating an orbital flight test as a possibility sometime in July.

A Chinese satellite launch center has experienced an explosion, according to a slew of high-resolution satellite images.

According to Spacenews.com, the explosion occurred at China's Jiuquan Satellite Launch Center located in the Gobi Desert between October 15 and October 16, 2021. Space enthusiast Harry Stranger found evidence of the explosion using images captured by Airbus and CNES (seen above). Reports indicate that the explosion didn't have any effect on China's future launches, as the nation's Shenzhou-13 mission launched from Jiuquan on October 15, 2021.

The publication reports that Chinese media didn't report on the explosion, which adds a certain mysterious element to what could have caused the explosion or what China was attempting to get off the ground. Spacenews suspects that China was attempting to construct, test, and launch solid rockets for orbital launches. This isn't the first time a launch was failed at the Jiuquan Satellite Launch Center, as the Kuaizhou-1A and Kuaizhou-11 rockets both failed.

The below video was captured by Yellowstone's helicopter manager and showcases why the national park is now closed.

Taking to its official Twitter account, the Yellowstone National Park explains that the north entrance road to the park through to the Gardner Canyon between Gardiner, Montana, and Mammoth Hot Springs has endured mass flooding. The fast-paced water has destroyed large portions of the road and has created an overall hazardous situation for anyone on the ground.

Yellowstone National Park explains in a follow-up tweet that the high volumes of water came from the adjacent river that has overflowed and eroded the road as well as some banks. This recent closure of the park marks the first time Yellowstone has been forced to close in 34 years. Notably, the floodwaters have broken all previously set records and have caused more than 10,000 visitors to evacuate the park. Furthermore, officials at the park have said that repairs to the affected area will likely take months to complete.

Elon Musk has posted to his personal Twitter account an image of the launch vehicle poised to land the first humans on Mars.

The above image showcases Starship SN24 in the "high bay" at what seems to be SpaceX's South Texas launch site called Starbase. The photograph from Musk comes a day after the Federal Aviation Administration (FAA) finally released its evaluation of the environmental impacts of Starbase, which requested SpaceX make more than 75 changes to its facility before the regulator can grant the space-faring company approval to launch Starship.

The report from the FAA puts SpaceX at a metaphorical yellow light, and the company seemingly took the news in stride as it wrote on its Twitter that it's now "one step closer to the first orbital test of Starship". Notably, the report from the FAA states it "Finding of No Significant Impact" for SpaceX's plans to conduct orbital launches with its Starship, or the Super Heavy rocket. Furthermore, the FAA will only approve SpaceX for five orbital and suborbital launches per year.

Amazon has updated the world on its upcoming Prime Air drone deliveries, where residents in Lockeford, California, will be some of the first people to get their deliveries... by drones.

The company has published a new blog post that explains that Amazon's teams of "hundreds of scientists, engineers, aerospace professionals, and futurists have been working hard" on the Prime Air drone delivery side of Amazon's continuously expanding business.

Lockeford is also no stranger to the aviation industry, with Amazon pointing out that one of the early pioneers of aviation -- Weldon B. Cooke -- built and flew planes in the early 1900s, and was a resident of Lockeford. Now, 100+ years later we're seeing the next generation of delivery technology: drone delivery. Lockeford residents will be providing feedback to Amazon over the Prime Air drones delivering packages to their backyards.

A study on the asteroid Ryugu titled "Samples returned from the asteroid Ryugu are similar to Ivuna-type carbonaceous meteorites" has been published in the journal Science.

Researchers have analyzed samples retrieved from the Ryugu asteroid by the Japan Aerospace Exploration Agency's (JAXA) Hayabusa2 spacecraft after a six-year mission to visit the asteroid about 300 million kilometers (186.4 million miles). Researchers from Okayama University discovered organic matter, including amino acids, that they believe "could give clues to the origin of life on Earth."

In analyzing a sample of asteroid dust and rocks weighing only 5.4 grams (0.2 ounces), the team found 23 different types of amino acids. Amino acids are theorized to have been created on Earth billions of years ago through a combination of lightning strikes and other primitive conditions. However, the presence of amino acids on Ryugu, an asteroid located far from off, shows that they can form elsewhere and may have been brought to Earth early on.

A study on the black hole titled "An isolated mass gap black hole or neutron star detected with astrometric microlensing" has been accepted for publication in the The Astrophysical Journal.

Researchers from the University of California, Berkeley (UC Berkeley) have discovered what they believe to be a free-floating black hole, the first black hole of its kind to be observed. Astronomers believe large stars leave behind black holes when they die; however, isolated black holes are invisible. It is hypothesized that hundreds of millions of such black holes exist throughout the Milky Way, born from the death of stars.

Researchers used gravitational lensing, which detects the brightening of a star that has been influenced by a strong gravitational field from a nearby object, in this case, a potential black hole. The object's mass is estimated to be between 1.6 and 4.4 times that of our Sun. The researchers caution that the object could be a neutron star, as it is believed dead stars must have masses 2.2 times greater than our Sun's to collapse into a black hole.

Russia is currently working on creating its own space station to use instead of the International Space Station (ISS).

The proposed Russian Orbital Service Station (ROSS), will use modules from the ISS in its creation. However, scientists from the Russian Academy of Sciences (RAS) are concerned about the possibility of "potentially pathogenic bacteria" from the ISS damaging materials aboard the new Russian space station.

When the Russian Mir space station was still operational, scientists during the 24th expedition on Mir recorded a failure of commutation equipment due to microorganism activity. According to Orlov, three options for ROSS' orbit are being considered. However, Dmitry Rogozin, the General Director of the Roscosmos, has indicated this and other facets of ROSS, like its general architecture and content, have already been determined.

An email obtained by BusinessInsider has revealed that Elon Musk will soon be speaking to Twitter employees for the first time since the deal to purchase the company went public.

The email sent by Twitter CEO Parag Agrawal informs Twitter employees that an all-hands meeting will be held on Thursday, June 16, and will feature SpaceX and Tesla CEO Elon Musk as a guest speakers. The email also states that employees will be able to submit questions for Musk to answer as soon as Wednesday and that Leslie Berland, Twitter's chief marketing officer, will be moderating the meeting.

Twitter employees have already been very vocal about wanting to speak to Musk about his plan to acquire Twitter and what that means for their jobs and the overall ethos of the company. Notably, Agrawal stated in the email that Musk will be asked questions that employees have proposed over the past weeks, which will no doubt cover topics such as layoffs, reenabling banned Twitter accounts (Donald Trump), and how "free speech" on Twitter will change under Musk's ownership.

The Federal Aviation Administration (FAA) recently concluded its investigation into the environmental impacts of SpaceX's Starbase facility located on Texas's Gulf Coast.

The assessment, which has been released online, requests that SpaceX make more than 75 changes to its facility before the regulator grants approval for the company to launch rockets to the Moon and beyond. Notably, the conclusion from the FAA has put a temporary stop to SpaceX's launch of Starship, the company's new next-generation rocket poised to be the transportation method that will be used to put humans on Mars.

However, as SpaceNews notes, the assessment didn't specifically state that Starship, or any coming orbital launches, will have any environmental impact, but more so, the requests are aimed at making SpaceX take the necessary steps now to reduce any future environmental impact. Furthermore, the recent review by the FAA puts a cap on the number of launches SpaceX can conduct per year - five orbital launches and five suborbital launches.

NASA has captured on video the Sun firing off a solar flare that was accompanied by a coronal mass ejection.

NASA used its Solar Dynamics Observatory to observe the solar event from multiple wavelengths, giving astronomers and Sun researchers a variety of ways to interpret the data. The Sun released its solar flare on June 13, where it shot large quantities of high-energy radiation into space for approximately eight hours. Officials reported that the flare reached M3.4, which places it in the "medium" power categorization, meaning it wasn't powerful enough to cause any significant impact to Earth.

Notably, Spaceweather reports that the solar flare also came with a coronal mass ejection (CME), which is a large cloud of plasma that is ejected from the Sun's corona, usually, after a solar flare occurs. The flare can be traced back to the sunspot group named AR3032 exploding. As for the CME, officials at the National Oceanic and Atmospheric Administration (NOAA) believe the CME will mostly pass Earth when it arrives on June 15 but may impact Earth's magnetosphere slightly.

New Zealand has new plan to impact climate change, and while initially it may sound like a ridiculous plan, officials believe it could have a big effect.

Reports indicate that a new draft proposal suggests implementing a new tax that would charge farmers for the amount of methane emissions produced by their livestock. According to the Food and Agriculture Organization of the United Nations, livestock methane and carbon dioxide emissions account for approximately 10% of greenhouse emissions created by human activity. Notably, there are about 1.4 billion cows in the world and each of them produce on average 500 liters of methane each day.

New Zealand plans to reduce its greenhouse emissions by creating a new tax scheme that would charge farmers on the approximate amount of methane produced by their livestock, and if passed the new scheme would begin taxing farmers in 2025. The draft proposal will also provide farmers with incentives to reduce their methane emissions by feeding their livestock a special diet as well as planting more trees. Lastly, the money generated from the tax would be rolled back into research and development to further reduce greenhouse gases across the country.

SpaceX and Tesla CEO Elon Musk has played a major role in curbing Putin's disinformation campaign, according to the Pentagon.

A recent report from Politico has revealed that Musk's Starlink satellites, which have provided much-needed internet access across Ukraine, have "totally destroyed" Russian President Vladimir Putin's information campaign and have provided as many as 150,000 Ukrainians with internet access every day.

To illustrate the importance of Starlink to Ukraine, Ukrainian president Volodymyr Zelensky said that in areas where Ukraine's traditional internet access was disconnected, Russian troops in the area informed residents that Ukraine was overrun with Russians and that country didn't exist anymore.
