NASA has taken images of astronomical observations and has converted them into "musical pieces" for your listening pleasure.

So, how does NASA do this? NASA takes observations made by NASA's Chandra X-ray Space Telescope and other ground-based telescopes and through a process called sonification, the space agency is able to convert the images into sound.

Three new sonifications have been released and they are sourced from observations made of the black hole named Messier 87, a cluster of young stars that are only a couple million years old and supernova explosion.Visualization scientist Kimberly Arcand, from the Chandra X-ray Center along with astrophysicist Matt Russo and musician Andrew Santaguida are responsible for the creation of the sonifications. If you are interested in learning more about the sonification process, check out this link here.

NASA has announced that it is pivoting the space agency's infrastructure to position itself better for the next 20 years.

The announcement came from NASA's Administrator Bill Nelson who said that the space agency will be separating the current "Human Exploration and Operations Mission Directorate into the new Exploration Systems Development Mission Directorate (ESDMD) and Space Operations Mission Directorate." Jim Free will be returning to the agency as associate administrator of ESDMD, and Kathy Lueders will be associate administrator of Space Operations Mission Directorate.

So, why did NASA do this? According to the press release, the space agency wants two separate missions with separate teams providing focused oversight on each respective mission. Splitting the mission up will allow the space agency's respective teams to focus on their areas, ultimately allow the team members to execute each mission with high success.

An asteroid that could be anywhere between 425 and 985 feet in diameter is approaching Earth at tens of thousands of miles per hour.

The asteroid is named 2021 NY1, and according to NASA's Jet Propulsion Laboratory Near-Earth-Object (NEO) tracking website, the asteroid will pass Earth safely at a distance of about 970,000 miles. NASA categorizes any object that passes within 120 million miles of the Sun as a NEO, hence asteroid 2021 NY1's classification.

In terms of distances in space, 970,000 miles is quite close to Earth as the Moon is only 238,855 miles away. NASA's NEO database describes 2021 NY1 as being roughly between three and six Statues of Liberty tall and that the space rock is traveling at around 21,000 mph, which is about 27 times the speed of sound. If you are interested in what asteroid has come the closest to Earth, that would be asteroid 2020 QG, which passed over the Indian Ocean at just 1,830 miles.

A surprise discovery has led researchers to believe that black holes may be more complex than what was initially thought.

According to a new study published in the journal Physical Review D, astronomers Xavier Calmet and Folkert Kuipers of the University of Sussex studied the changes in gravitational forces that are changed by quantum particles located at the edge of the black hole. What they found after running their calculations was an anomaly appeared that they couldn't explain. The researchers concluded that what they saw in their calculations was black holes have pressure.

Xavier Calmet, Professor of Physics at the University of Sussex and an author on the study, explained, "Our finding that Schwarzschild black holes [static black holes without electric charge and angular momentum] have a pressure as well as a temperature is even more exciting given that it was a total surprise. I'm delighted that the research that we are undertaking at the University of Sussex into quantum gravity has furthered the scientific communities' wider understanding of the nature of black holes."

NASA has detailed an upcoming mission that is part of its Artemis program, which is slated to put humans back on the Moon.

The mission involved a rover called "Volatiles Investigating Polar Exploration Rover," or VIPER for short. NASA has said via the above YouTube video that the VIPER mission will be the very first resource mapping mission to ever be conducted on the surface of another celestial body. VIPER will be landing in the Nobile Crater located at the Moon's South Pole and will be searching for water in its designated area.

VIPER will be traversing 10 to 15 miles of the Nobile Crater that cover approximately 36 square miles. The rover will be visiting carefully selected locations of scientific interest, such as craters that are permanently in darkness, water-ice locations, and more. The rover will collect samples from three drill locations, and each of the locations varies in temperature.

Imagine a future where houses are painted with a specific paint that reflects virtually all of the sunlight, keeping your house cooler and thus requiring less electricity -- massively better for the environment.

Purdue University researchers have created an ultra-white paint that is not just the whitest paint ever made, but this new paint could eventually reduce or even remove the requirement for having an air conditioner. The researchers began their journey looking to reflect sunlight away from buildings, but it has turned out so good that the team made it into the Guinness World Records.

The new white paint reflects 98.1% of solar radiation, while it also emits infrared heat -- thanks to it absorbing less heat from the sun that it emits -- the surface of anything that this paint covers would be cooler below the surrounding temperature, without using power. This is quite the reverse of an AC unit and even regular commercial white paints.

A new study by archaeologists has explored the ruined city of Tall el-Hammam that existed around 3,600 years ago in the Levant.

The ancient city is situated on high ground in the southern region of Jordan Valley, northeast of the Dead Cell. Researchers believe that during its peak, Tall el-Hammam would have been one of the largest and most continually occupied cities throughout the Levant.

Researchers in the new study detail the discovery of "highly unusual" materials such as pottery shards with outer edges melted, building material melted, and other evidence of extremely high temperatures in the area, which wasn't possible with the technology of the Bronze Age. James Kennett, emeritus professor of earth science at UC Santa Barbara, said, "We saw evidence for temperatures greater than 2,000 degrees Celsius".

NASA's Jet Propulsion Laboratory (JPL) has explained what appears to be something that would be seen in a science fiction movie. However, this is real and will be done relatively soon.

It's called solar electric propulsion, and it is a different kind of propulsion system that is a step away from traditional methods of travel in space. NASA explains on the JPL website that a solar electric propulsion system will be equipped to NASA's Psyche spacecraft that will be launched towards a metal-rich asteroid called Psyche.

Instead of using traditional methods of propulsion, Psyche will electric propulsion, which consists of the spacecraft carrying tanks full of xenon, and solar arrays that convert sunlight into electricity that power the onboard thrusters. NASA explains, "The spacecraft's four thrusters will use electromagnetic fields to accelerate and expel charged atoms, or ions, of that xenon. As those ions are expelled, they create thrust that gently propels Psyche through space, emitting blue beams of ionized xenon."

A new study suggests that Jupiter's atmosphere contains the answer to a long-standing mystery with Neptune and Uranus.

According to a study by Tristan Guillot, the mystery of why Neptune and Uranus lack ammonia in their atmospheres when compared to other gas giants may have just been answered. Guillot suggests that mushballs are what is responsible for the lack of detection. Mushballs are large hailstones that can contain large amounts of ammonia and water.

Guillot suggests that these mushballs form in the atmosphere and then carry the ammonia down into the thick atmospheric clouds and below the layer our instruments can detect. The basis of this theory was founded on a discovery that occurred on Jupiter. Researchers used NASA's Juno spacecraft that's orbiting Jupiter to observe ammonia hailstones forming when storms were occurring. These hailstones carried ammonia deep into Jupiter's atmosphere.

A team of researchers have published a new study that provides evidence that the size of a planet may be a determining factor in whether it will be able to contain water for extended periods of time.

The new study has been published in the journal Proceedings of the National Academies of Sciences and provides evidence that the size of a planet impacts habitabilty. The researchers looked at 20 meteorites that are representative of Mars' overall composition and measured the amount of potassium (K) isotopes that are within them.

Using K as a tracer for more "volatile" elements and compounds, the researchers were able to find correlated evidence that suggests that smaller planets lose lots of water during formation and that global magnetic fields shut down, which eventually causes the atmosphere to thin. Mars is an example of this.

As part of its Artemis program, NASA will be sending a lunar reconnaissance rover to the surface of the Moon to search for water.

In a new press release published on the NASA website, the space agency details the Volatiles Investigating Polar Exploration Rover (VIPER) and where it plans on landing it. According to the press release, SpaceX will be delivering VIPER to the Nobile Crater located at the Moon's South Pole. NASA selected this landing location with several parameters in mind, and those were; suitable terrain for the rover, temperature variation, solar charging locations, and presence of water-ice.

The Nobile Crater is the most viable location for VIPER to land, and once it arrives in 2023, it will begin to explore a region of the surface that is approximately 36 square miles. Throughout its 100 day mission, NASA expects VIPER to traverse 10 to 15 miles of its landing area, exploring areas NASA researchers have been carefully assessing with data from remote sensing instruments. VIPER's main mission is to search for water-ice, and NASA believes that ice and other resources exist in "permanently shadowed areas of the Moon near the poles."

NASA has announced a new contest where it will review proposals from private companies for the construction of new space stations in Earth's orbit.

The space agency has said that the International Space Station is expected to be retired by the end of the decade, and instead of constructing a new space station itself, NASA is giving the opportunity to private companies. By doing this, NASA expects to save around $1 billion per year. According to Phil McAlister, NASA's director of commercial spaceflight, NASA has already received "roughly about a dozen proposals" from private companies, with 50 companies in total expressing interest in the new program.

Under the Commercial LEO Destinations project NASA will award two to four companies with the best proposals up to $400 million in contracts. McAlister added, "This strong industry response shows that our plan to retire the International Space Station in the latter part of this decade and transition to commercial space destinations is a viable, strong plan. We are making tangible progress on developing commercial space destinations where people can work, play and live."

NASA is has announced that it's willing to award private companies up to $400 million to construct private space stations in Earth's orbit.

The space agency is looking towards the future of how humans are going to be conducting science in microgravity, and so far, all of the research has been coming from the International Space Station (ISS). However, the ISS won't last forever, and it was only recently that astronauts aboard the floating laboratory reported new cracks in one of the modules, more on that here.

Instead of NASA constructing its own new ISS, it is putting the job up for offer with private companies. According to NASA's commercial-spaceflight director, Phil McAlister, who spoke to a CNBC reporter, the new $400 million program has "received roughly about a dozen proposals". Of NASA's proposals from private companies, the space agency will select two to four winners and divide the $400 million budget between them.

Astronomers have detailed in a new study what the bright cosmic object was that lit up the sky over Japan and China back in 1181.

Historians and astronomers have been attempting to find an answer for what contemporary astronomers recorded seeing in the sky in 1181. According to accounts from these astronomers, onlookers of the sky saw a bright light that resembled the same brightness level as Saturn.

This bright light remained in the night sky for six months, according to historical accounts of the event. Now the mastery of the bright light in the sky may be uncovered as a new study has tracked a cosmic event back to around 1181.

A team of researchers has created holograms that users can actually feel, which very well may be the first step towards StarTrek-level technology.

The team of researchers is from the University of Glasgow, and according to a report by researcher Ravinder Daahiya written in The Conversation, the team uses a technology called "aerohaptics". So, how does it work? Users of the hologram are blasted with jets of air, or "aerohaptics," which simulate the sensation of touch on people's fingers, hands, and wrists.

Daahiya explains that the team of researchers tested the jets of air with an interactive projection of a basketball. Daahiya says that the system provided the appropriate amount of simulated weight to the basketball, causing the overall experience to be quite convincing. Daahiya wrote, "Those jets of air deliver a sensation of touch on people's fingers, hands, and wrists."

The Inspiration4 crew arrived safely back on Earth this past Saturday with SpaceX's Dragon capsule touching down safely in the Atlantic Ocean

The crew of four ordinary people were up in lower-Earth orbit for three days, and throughout that time the crew enjoyed some music, did science experiments and enjoyed an incredible view at Earth from Dragon's cupola. Jarrad Isaacman, the sponsor and commander of the mission wanted to raise money for St Jude Children's Research Hospital. Isaacman reportedly paid SpaceX an undisclosed amount of money for the trip, as well as gave $100 million to St Jude Children's Research Hospital.

As a welcome home present, SpaceX CEO Elon Musk counted himself in for $50 million to be donated to the St Jude Children's Research Hospital. Musk dropped the welcoming him present on a tweet from the team that said they are back on Earth and are "Happy. Healthy. Home." SpaceX mission control said when the Inspiration4 Crew was landing, "On behalf of SpaceX, welcome back to planet Earth. Your mission has shown the world that space is for all of us."

Rolls-Royce is currently working on a power source for mining resourcing on the Moon and even Mars.

The firm recently released a joint study with the UK Space Agency into nuclear reactor development for space rockets and mining. The firm is taking a look at how a micro-nuclear reactor could be implemented into a rocket and then redeployed as a power source for mining on the Moon and mining on Mars. The head of Rolls-Royce's defense division, Dave Gordon, said that the firm can utilize its 60-years of development experience making nuclear-powered submarines for the Royal Navy and apply it to nuclear rocket/space mining development.

Gordon said rockets and submarines are similar in the following ways, "non-air breathing environments, long-endurance, super reliable with a very dense power source." Gordon goes on to say that there aren't very many rare metals on Earth and that other objects in space have an abundance of these metals. Mining these metals will require a power source, and Gordon argues that the power source will have to be nuclear and not solar. For more information on this story, check out this link here.

SpaceX has just successfully made history with their Inspiration4 mission, raising $210 million for St. Jude Children's Research Hospital, and sending four civilians into space.

Elon Musk wasn't happy about the news, with someone tweeting him asking: "The President of the United States has refused to even acknowledge the 4 newest American astronauts who helped raise hundreds of millions of dollars for St. Jude. What's your theory on why that is?"

The Tesla and SpaceX founder tweeted back, simply saying: "He's still sleeping".

SpaceX has announced the date and time for when the Inspiration4 crew will return to Earth.

The Inspiration4 crew took off from the Kennedy Space Center on September 16 on the back of SpaceX's Falcon 9 rocket. The success of the launch marked a milestone in the space tourism industry as the first all-civilian flight into space. According to SpaceX CEO Elon Musk, the crew onboard SpaceX's Dragon capsule is happy and healthy, who announced that he has recently checked in with the crew to see how they are doing up in lower-Earth orbit.

The crew has been in lower-Earth orbit for a few days, and according to an update from the SpaceX Twitter account, Inspiration4 is slated to return back down to Earth on Saturday, September 18, at 7:06 pm EDT. The Dragon capsule will splashdown in the Atlantic Ocean off the coast of Florida, where a team will be waiting to recover them.

SpaceX recently launched its Falcon 9 rocket, and onboard the rocket was the Inspiration4 crew, who are currently floating around in lower-Earth orbit.

The launch for SpaceX was a success and marked a milestone for the space tourism industry as the very first all-civilian flight to space. The launch took place from the Kennedy Space Center located in Florida and stunned onlookers as the Falcon 9 soared off into the sky at high speeds. Throughout this article, you will find some of the best videos and images taken of the launch.

The crew aboard SpaceX's Crew Dragon capsule will have one of the best views of Earth through the cupola. Since the Inspiration4 mission doesn't take the passengers on board to the International Space Station, SpaceX has modified the Dragon capsule and has replaced the docking mechanism with a cupola or glass dome. Passengers onboard Dragon will be able to enjoy a stunning 360-degree view of Earth.
