A group of scientists have created a high-power laser beam that they claim lightning will follow for a period of time.
Physicists have published a new study in the scientific journal Nature Photonics that explores the use of a high-powered laser beam to control where lightning strikes in what seems to be the successor to the still-in-use lightning rod. The idea behind the laser beam is to protect areas such as airports, rocket launch pads, and other infrastructure that is vulnerable to electrical damage from rolling thunderstorms that spawn lightning strikes.
Benjamin Franklin first proposed the lightning rod that is still widely used today to protect buildings from lightning strikes in around 1750. The rod or lightning conductor is a large metal rod mounted on a structure that routes lightning into the ground, protecting the building from any electrical damage. While Franklin suggested the idea, the design of the lightning rod was perfected by Nikolas Tesla.
Researchers have discovered that Saturn's moon Enceladus was far more tectonically active than previously thought after analyzing recent measurements of material from the moon's surface.
A new study published in the scientific journal Icarus details measurements conducted on the material that coats the surface of Saturn's moon Enceladus. According to the study, the material is called 'regolith' and has an appearance very similar to snow found on Earth. However, Enceladus' snow isn't formed the same way normal snow is formed on Earth.
The researchers explain that the regolith is created through snow cannon-like plumes, or ice geysers erupting and shooting large quantities of particles up into the atmosphere that then fall back down to the moon's surface. Smaller particles launched by the eruption are shot into space and eventually become part of Saturn's iconic rings. While scientists are quite sure that Enceladus' snow is coming from surface eruptions, the researchers are in the dark when it comes to the physical properties of the regolith material.
A college student has used Open AI's chatbot called ChatGPT to write an essay about burqa bans that they then submitted for grading.
According to a report from The New York Times, the student confessed to using the chatbot to write the essay after their teacher, philosophy professor Antony Aumann from Northern Michigan University, busted them. Aumann explained to Futurism that the student was instructed to rewrite the essay, which is what is done the majority of the time in plagiarism cases.
Chatbots such as OpenAI's ChatGPT are free and have very powerful capabilities that are resulted in them going viral. ChatGPT is an artificial intelligence designed to have human-like conversations where it remembers what was talked about earlier in the conversation. Additionally, users make improvements to the AI's answers, write code, essays, format data, create programs, and more. An example of a prompt would be, 'write an essay on burqa bans'. A more simpler request could be, 'Got any creative ideas for a 10 year old's birthday?'
A rogue asteroid has been spotted photo-bombing NASA's Hubble Space Telescope's field of view as it attempts to observe a nearby galaxy.
The European Space Agency (ESA) has taken to its website to explain the "visitor to a galaxy", as displayed in the above image. The above image was captured by NASA/ESA's Hubble Space Telescope that was pointed at the small galaxy known as UGC 7983, which appears as a hazy cloud of light in the center of the image.
This small galaxy is located approximately 30 million light-years from Earth within the constellation Virgo and is categorized as a dwarf irregular galaxy that is believed to be one of the earliest galaxies to form in the universe.
A team of astronomers has used the Green Bank Telescope to capture what is now being described as the most detailed image of the Moon ever taken from Earth.
A new report from BGR has claimed that the new images of the surface of the Moon by the Green Bank Telescope are the most detailed photographs humans have captured from the surface of Earth. The Green Bank Observatory took to its website to explain that it used the National Science Foundation's Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA) to capture the highest-resolution radar images of the Moon, which will be used to pave the way for next-generation radar systems that'll study planets, asteroids and other moons within our solar system.
The press release states that a low-power radar transmitter, capable of 700 watts of output power at 13.9 GHz, was tested on the GBT. Astronomers aimed the telescope at the Moon's Tycho crater "An image of the Tycho crater was captured with a 5-meter resolution, showing unprecedented detail of the Moon's surface from Earth. "It's pretty amazing what we've been able to capture so far, using less power than a common household appliance," emphasizes Patrick Taylor, radar division head for GBO and NRAO."
Elon Musk's private jet was very active throughout 2022, with the Tesla and SpaceX CEO taking more than 100 flights in total.
Musk has publicly stated many times that he is attempting to save the planet through the reduction of greenhouse gas emissions. Tesla and the electric vehicles it produces are a reflection of these statements, and it quickly became a pioneer of the electric vehicle industry. However, some question Musk's effort for a cleaner world and point to the emissions that are produced by his private jet.
According to a report that cites a bot that tracks Elon Musk's private jet whenever it takes off and lands at an airport, Musk has taken a total of 134 flights throughout 2022, with the billionaire doing international travel to eight different countries. The Twitter account also estimated the total amount of CO2 produced by Musk over his travels, and according to reports, Musk's Gulfstream G650ER private jet burns 503 gallons of fuel for every hour of flight, meaning it burnt 178,686 gallons or 709,578 liters of fuel during the year and produced 1,895 tons of CO2 emissions.
The world's most populated nation has recorded its first population decline in declares, according to a new report released by the National Bureau of Statistics.
The new report was released on Tuesday and stated that China had 850,000 fewer people at the end of 2022 than it did at the end of 2021. Notably, the report states that the census of people included populations in mainland China and excluded places such as Hong Kong and Macao. The report goes on to state the nation's total was 1.41 billion people, with 9.56 million births against the 10.41 million deaths recorded.
Furthermore, the report found that Chinese men greatly outnumber Chinese women, with the report finding there are 722.06 men and 686.69 million women. This disparity between total men and women can be, at least in part, attributed to the strict one-child policy that was implemented in the late 1970s / early 1980s. The one-child policy was abandoned in 2016 and was followed by Chinese authorities encouraging residents to have multiple children.
A group of researchers has tested the effects of robotic AI-powered fluffy seals on astronauts as part of an overarching effort to eventually send the sophisticated toys into space.
A new article in the South China Morning Post details a group of researchers that created fluffy robotic baby seals called Paros. These machines are designed to alleviate the stress and loneliness experienced by astronauts living on Mars throughout the early stages of the colonization process. The robotic seals have already been tested in a simulation where a crew of six spent two weeks in a simulated Mars environment operated by the Mars Society in Utah.
The simulation required the crew to perform first-aid drills, grow their own food, and take rock and soil from Mars. Additionally, the crew tested a Paro that was given to half of the crew for the first week and the other half of the crew the following week. Notably, the robotic seal is equipped with a dual 32-bit processor, three microphones, 12 tactile sensors, touch-sensitive capabilities via its whiskers, and several motors and actuators that give it its limited movement. The stress-relieving robot measures in at 22 inches from head to tail and weigh 5.7 pounds.
Elon Musk has shared a video to his Twitter account showing what he believes will be how humans land on the Red Planet in the future.
The Twitter, Tesla, and SpaceX CEO shared a video posted on the SpaceX Twitter account, which showcased the Falcon Heavy rocket safely landing back on the launch pad after completing its mission from the U.S. Space Force. Elon Musk's company launched the Falcon Heavy from Launch Complex 39A at Kennedy Space Center, Florida, on January 15 at 5:56 p.m.
The mission titled USSF-67 was to geostationary orbit and carried a payload that featured the U.S. Space Force's Continuous Broadcast Augmenting SATCOM (CBAS)-2 communications satellite, a satellite designed to relay data from existing satellites and the Long Duration Propulsive ESPA (LDPE)-3A, a 6-slot payload adapter made by Northrop Grumman that had five slots taken up by military satellites.
A team of researchers has examined a meteorite that crashed into a family's driveway only a few years ago and found that it contains organic matter.
A new study published in the journal Science Advances details the discovery of organic matter that contains a selection of the building blocks of life or the molecules/compounds required for carbon-based life to exist. Scientists examined the composition of the meteorite and found traces of soluble protein amino acids that they believe formed much earlier in the meteorite's life. Researchers explain that the organic matter likely formed when the meteorite was attached to its much larger parent asteroid that harbored liquid water.
It should be noted that this isn't the very first-time researchers have discovered organic matter inside of a space rock that has fallen to Earth, but considering the results from the examination and the way the meteorite was discovered (in a driveway), this particular meteorite has entered into the "rare" category, according to study lead author Queenie Chan, a planetary scientist at the University of London. Chan explains that the Winchcombe meteorite "belongs to a rare type of carbonaceous meteorite which typically contains a rich inventory of organic compounds and water".
