The asteroid called 2023 BU was discovered by astronomers Gennadiy Borisov at the MARGO Observatory in Crimea. The asteroid was identified, and calculations were performed that estimated the small space rock will make its closest approach to Earth on January 26 at an altitude of just 2,178 miles above the surface of the Earth.

For perspective, geostationary orbit is at an altitude of approximately 22,000 miles. This level of orbit is commonly used by satellites that are locked into a circular synchronized orbit around Earth, in which the satellite's orbital period is the same as Earth's rotation period of 23 hours and 56 minutes (1 day). Researchers estimate that 2023 BU has a diameter between 12 and 28 feet, and since it's relatively small, it will be difficult to spot without a powerful telescope and a skilled operator.

The world's most powerful observatory, the James Webb Space Telescope, has used its instrument to make a breakthrough discovery.

Chamaeleon I

NASA has taken to its blog on its official website to announce that the James Webb Space Telescope (JWST), operated by an international team of astronomers, has discovered an inventory of the deepest, coldest ices measured to date. The space agency explains that knowledge of interstellar ice is very valuable as ices will be a crucial ingredient for building a habitable planet off Earth.

These ices contain vital elements such as carbon, hydrogen, oxygen, nitrogen, and sulfur. Notably, these elements are key ingredients for a viable planetary atmosphere and molecules such as sugars, alcohols, and simple amino acids vital for life. Webb's sensitive instruments were pointed at the Chameleon I cloud located in the southern constellation of Chameleon, some 500 light-years away from Earth.

Watching Boston Dynamics' Atlas robot in action is a glimpse into the future

Kosta Andreadis | Jan 23, 2023 8:28 PM CST

Boston Dynamics' Atlas robot is one of the most advanced humanoid robots, and if you've seen a clip of it in action over the years, then you'll no doubt have been impressed by how it moves. Now equipped with hands, Boston Dynamics has released a new video of Atlas on a mock construction site as a worker up on a scaffold realizes he's forgotten his tool bag.

Elon Musk confirms Twitter Blue will get more expensive

Jak Connor | Jan 23, 2023 7:02 AM CST

Twitter owner Elon Musk has confirmed that Twitter Blue will soon get a more expensive option for users that wish to remove advertisements from the platform entirely.

The news came from Musk, that took to his personal Twitter account to announce that advertisements are "too frequent on Twitter" and are "too big". The Tesla CEO went on to explain that development teams are tackling both of these issues in the "coming weeks" and that there will be a "higher-priced subscription that allows zero advertisements". These announcements of new revenue streams from Musk come at a crucial time as the company is suffering from a dramatic loss in advertising expenditure from big-name advertisers and ad agencies.

Notably, reports from last week indicated that Twitter wants its old and new advertisers so badly that it's giving away $250,000 in ad spend to specific companies that spend $250,000 on the platform. This means a company would get $500,000 in ad spend on Twitter if they bought $250,000 of ads. Advertisers left or temporarily stopped spending on Twitter following Musk's takeover in late October, with many former advertisers citing Musk's unpredictable behavior on the platform, changes to the platform's content policy, and layoffs.

Scientists use high-powered laser beam to steer lightning bolts

Jak Connor | Jan 23, 2023 5:31 AM CST

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.

Scientists point to weird Saturn moon for a prime place to look for new life

Jak Connor | Jan 23, 2023 4:31 AM CST

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.

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 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.

Scientists snap the most detailed image of the Moon ever taken from Earth 88

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."

Here's how much CO2 Elon Musk's private jet spewed out in 2022

Jak Connor | Jan 17, 2023 8:35 AM CST

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.
