Astronomers are constantly looking out into the void of space, attempting to discover something that they haven't before.

Now, a team of astronomers believe they have located what should be considered as the fastest-orbiting asteroid in our solar system, asteroid 2021 PH27's. Astronomers discovered that this asteroid had the shortest orbital lap of the sun of just 113 days, the shortest known orbital lap of any object in our solar besides Mercury, which takes just 88 days.

The asteroid was first discovered on August 13 by astronomers that were using the Dark Energy Camera (DEC). Astronomers estimate that the asteroid is around 0.6 miles in diameter and that the asteroid originally came from the asteroid belt that is located between Mars and Jupiter. Additionally, researchers believe that it's likely the asteroid will collide with either Mars or Venus in the next few million years.

SpaceX has now shipped over 100,000 of its Starlink terminals, giving people across the planet satellite broadband access with some users reporting in with impressive speeds.

The news broke from SpaceX founder himself Elon Musk, where he hip-fired a simple tweet that reads: "100k terminals shipped!" and that's it. SpaceX has officially shipped 100,000 of its Starlink terminals, offering 50-150Mbps of internet with latencies between 20-40ms across the planet.

SpaceX has been pushing to offer half the population of the planet with its Starlink internet service, but with huge demand for Starlink the availability of the internet service has been pushed back into 2023. We might be a few years out before Starlink can fulfill its own promises, for the end of 2021... a couple of years from now.

Blue Origin has been fighting tooth and nail since NASA decided it was going to award SpaceX with a $2.9 billion dollar contract for the construction of a new lunar lander.

Originally, NASA was planning on awarding two separate contracts, but according to the space agency, it only received a fraction of the budget it requested for the Artemis lunar landings, which resulted in only one contract being available. Blue Origin formally protested the decision, and the contract was paused for 95 days while the US Government Accountability Office (GAO) reviewed NASA's decision, eventually resulting in the GAO dismissing it.

After having its protest dismissed, Blue Origin has now filed a complaint against NASA with the US Court of Federal Claims, saying the lawsuit was "an attempt to remedy the flaws in the acquisition process found in NASA's Human Landing System." Now, NASA has agreed to halt all construction to do with the contract with SpaceX, according to Reuters.

Two doctors are setting out to create one real-life "impulse engine," which appears in the legendary sci-fi TV show Star Trek.

Star Trek is no stranger to inspiring individuals to push the realm of real-world technological possibilities, and now two scientists are settings out to create a piece of technology that was used to break out of the orbit of a planet quickly called an "impulse engine". According to a Nerdist article, Dr. Hal Fearn and Dr. Jim Woodward have teamed up to create the "impulse engine" using some controversial physics that are explained quite clearly in the above video.

Woodward has been working on this question of using the universe's gravitation field as a means of movement for more than thirty years, and now NASA has officially funded a study for the experiment to be replicated by the US Naval Research Laboratory. As outlined in the video, Fearn, Woodward, and a representative for the Naval Research Laboratory have said that the idea is very fringe and has yet to be proven. The main issue is that it's challenging for everyone involved to prove, which is a problem for all new ideas in science.

A relatively new study has been able to predict the exact date for asteroid Bennu's highest chance of impacting Earth.

NASA created the Planetary Defense Coordination Office (PDCO) back in 2016 with the goal of having a team of individuals monitoring any asteroids that may be potentially dangerous to Earth. Additionally, the team is also tasked with finding prevention methods if an asteroid is found to be dangerous. Asteroid Bennu is categorized as potentially dangerous as its orbits will come within 125,000 miles.

At the moment, Bennu is located about 200 million miles away, but according to Freethink.com, it was discovered that in the year 2135 the asteroid that's anywhere between 0.31 miles and 6.2 miles in diameter, will pass within 125,000 miles of Earth, or about half the distance between Earth and the moon. PDCO Director Lindley Johnson spoke to the New York Times and said, "[A] half-kilometer-sized object is going to create a crater that's at least five kilometers in diameter, and it can be as much as 10 kilometers in diameter."

A self-healing "blob" that is extremely bizarre will soon be making its way to Earth after spending some time aboard the International Space Station (ISS).

The International Space Station (ISS) is home to many strange and exotic experiments as the researchers aboard the floating laboratory test the impact of microgravity. NASA launched the strange blob on the Cygnus cargo trip to the ISS last month, and the blob is actually formally named "Physarum polycephalum" - a single cell slime mold. So, why is NASA sending slime mold to the ISS?

The strange yellow mold is headed back down to Earth so science students aged between 8 and 17 can perform experiments on it. The mold is capable of self-healing and can survive dormancy through dehydration. The idea behind the tests will be to compare mold that has been experimented on in space for about a week to the mold back on Earth. Students and teachers will be looking for behavioral changes in the mold.

A new report has revealed that Jeff Bezos' Blue Origin has lost at least 17 top staffers after NASA awarded SpaceX with the lunar lander contract.

Following up on the report of a top engineer from Blue Origin switching jerseys over to SpaceX, CNBC has reported that at least 17 top staffers that were working on Blue Origin's lunar lander project have left the company. The reported departure of the staffers has come after NASA awarded SpaceX with the $2.9 billion lunar lander contract that is for getting humans back on the moon by 2024.

CNBC also reports that among the staffers that left were key leaders and top engineers and that they left in the weeks after Blue Origin founder Jeff Bezos took his spaceflight. Nitin Arora and Lauren Lyons, who were previously engineers at Blue Origin, have now announced work at Elon Musk's SpaceX and Firefly Aerospace. If you are interested in reading who departed the company, check out the list below.

The Hubble Space Telescope is no stranger to capturing incredible images of the cosmos and all of the stranger phenomena that lie within it.

So, what has Hubble captured this time? A phenomenon that is dubbed gravitational lensing, which was actually previously predicted by Albert Einstein. Gravitational lensing occurs when a large amount of matter is present, creating a gravitational field that then magnifies and distorts light that is coming from behind it. Essentially, the phenomenon is much like looking through a cosmic magnifying glass.

Hubble has captured an image of gravitational lensing in action with the above image showcasing the distorted light rays caused by two galaxies. The European Space Agency said, "Hubble data also indicates that there is a seventh spot of light in the very center, which is a rare fifth image of the distant quasar. This rare phenomenon is caused by the presence of two galaxies in the foreground that act as a lens." If you are interested in reading more about this story, check out this link here.

Astronomers are constantly learning new and wonderful things about the planets in our solar system, and Saturn is in today's spotlight.

Researchers used data acquired by NASA and the ESA's Cassini mission that orbited Saturn between 2004 and 2017. With the data, researchers set out to study the core of the planet and found that it may not have been as solid as astronomers previously estimated. The team of astronomers from the California Institute of Technology (Caltech) found that the core is better described as a "diffuse soup of ice, rock, and metallic fluids".

Jim Fuller, assistant professor of theoretical astrophysics at Caltech and co-author on the study, said, "We used Saturn's rings like a giant seismograph to measure oscillations inside the planet. This is the first time we've been able to seismically probe the structure of a gas giant planet, and the results were pretty surprising."

In an article published in The Conversation by Emily Ury, a Ph.D. candidate at Duke University, it's outlined that "ghost forests" are appearing along the Atlantic coast.

Ury is an ecologist that is studying the response of sea levels rising and the impact it has on the wetlands. An example of this would be climate change impacting the occurrence of floods and landscapes along coasts, which as a result then impacts environmental changes for wildlife, ecosystems, and businesses. Ury worked on a study in North Carolina that aimed at inspecting the effect salt levels have on plants and soil in wetlands.

Ury found after analyzing the salt levels in the soil for two years with her research team that rising sea levels are causing salt water to slowly seep into the coastal wetlands, which are causing trees that aren't tolerant to salt to die. The team of researchers also used NASA's Earth Observing System to get a birds-eye view of forest conditions and found, "We found that more than 10% of forested wetland within the Alligator River National Wildlife Refuge was lost over the past 35 years. This is federally protected land, with no other human activity that could be killing off the forest", wrote Ury.

Space junk will increasingly become a larger issue as humans continue to launch more objects into space.

One of the main components to reducing the amount of space debris floating around our planet is to ensure that satellites already positioned in orbit don't collide with each other. According to Hugh Lewis, the head of the Astronautics Research Group at the University of Southampton, U.K, SpaceX's Starlink satellites are responsible for half of all encounters between two space crafts.

Lewis also says that Starlink satellites are involved in around 1,600 close encounters per week. A "close encounter" is defined by two spacecrafts passing each other within 0.6 miles. Lewis is also the leading expert on space debris in Europe and said, "I have looked at the data going back to May 2019 when Starlink was first launched to understand the burden of these megaconstellations. Since then, the number of encounters picked up by the Socrates database has more than doubled and now we are in a situation where Starlink accounts for half of all encounters."

NASA is going to attempt to deflect an asteroid with something the space agency has been working on for more than two years.

NASA calls it the "Double Asteroid Redirection Test," or DART for short, and the mission involves NASA launching a spacecraft that will rocket towards the Didymos binary asteroid and collide with it. NASA wants to test if the impact of the spacecraft colliding with the asteroid will be enough to alter its course. It should be noted that the asteroid doesn't currently pose any threat to Earth and that NASA is purely conducting this mission for research purposes.

According to NASA's latest update on DART, the spacecraft recently received solar arrays that will be a core component to getting the spacecraft all the way to the Didmos asteroid system. The spacecraft will travel for ten months to reach the asteroid system and will launch aboard SpaceX's Falcon 9 rocket this November. When the spacecraft collides with the asteroid, it will be traveling at around 15,000 mph, and NASA will have Earth-based telescopes aimed at the asteroid for clear observation.

Over the weekend, you will be able to look up into the night sky and see one of the rarest full moons of the entire year.

So, what is a Blue Moon? The name "Blue Moon" was given to the moon for how extra full it looks in the sky during a certain period of time during the year. As for an official definition, a moon is deemed a "Calendrical Blue Moon" when there's a second full moon within the same month. Additionally, there is a "Seasonal Blue Moon", which is when there is a second full moon within an astronomical season, such as the Fall Equinox, the Winter Solstice, the Spring Equinox, and the Summer Solstice.

As for August's Blue Moon, it will be at its peak on Sunday, August 22, at at 8:02 a.m. Eastern, however, it will still be visible on the night of August 21 for those that wish to stay up late rather than getting up early on August 22. It should also be noted that the moon won't actually appear a blue color, which is no doubt disappointing for some excited people.

A woman has conducted a news conference in front of the Lincoln Memorial in Washington, D.C, where she said that she has met aliens at their base in the United States.

Angelia Lynn Johnston, who is going by the alias Anjali, held a news conference in front of the Lincoln Memorial where she explained that she has been in contact with aliens at their base located in the Mojave Desert. Johnston also claimed that she will be bringing astronauts and scientists to the secret base to meet with the "higher beings".

Johnston also claims that she is a retired defense intelligence officer who met two strangers who showed her the tunnels to the alien base. Upon entering the tunnels, Johnston says she met two alien life forms from two separate races who communicated with her telepathically (via her consciousness). The news conference was produced by TT Products, who will be following up with Johnston on her story.

Elon Musk hosted his new Tesla AI Day today, and the huge multi-hour show is worth a watch and has some incredible technology that was teased -- but one of them is that Tesla is building its own robot, the Tesla Bot.

The new Tesla Bot is 5'8" and weighs 125 pounds, it is built from "lightweight materials" and has "human-level hands". There are 40 electromechanical actuators through the arms, neck, torso, hands, and legs which will make the Tesla Bot the most human-looking and moving robot yet.

Inside, there's next-gen AI inside with Tesla's FSD (Full-Self Driving) computer inside of the Tesla Bot, with autopilot cameras feeding into neural networks with neural net planning allowing the robot to be the most advanced robot on Earth. Musk said that they wanted to build a robot that would navigate the world that was built for humans, but they made it small enough and weak enough that you'll be able to overpower it or outrun it -- probably.

A top engineer that was working on Jeff Bezos' Blue Origin lunar lander project has changed team over to Elon Musk's SpaceX.

The news of the lead engineer for Blue Origin's lunar lander leaving to join SpaceX comes after Jeff Bezos' Blue Origin had its protest denied by the US Government Accountability Office (GAO) to overturn NASA's decision to award a $2.9 billion contract to Elon Musk's SpaceX for the construction of a new lunar lander. The lead engineer is named Nitin Arora and announced his transition to SpaceX via a LinkedIn post, where he said, "Friday (August 13th) was my last day at Blue Origin."

Adding, "It was one hell of a ride working on the lunar program. Really honored that I got a chance to work with and lead incredibly smart, passionate people over last three years ... Next stop, SpaceX!" After the decision the GAO made, Blue Origin has been swinging at SpaceX's proposed plan to get humans back on the moon by posting infographics that compare its own methods to SpaceX's.

This weekend an asteroid that NASA deems as potentially dangerous will make an approach relatively close to Earth.

On August 21 at around 11:10 a.m EDT, the asteroid named 2016 AJ193 that is estimated to be approximately 4,500 feet in diameter, will fly past Earth at more than 58,000 miles per hour. NASA has classified the asteroid as potentially hazardous. However, the asteroid will actually pass by Earth at around nine times the distance between Earth and the moon.

NASA's Center for Near-Earth Object Studies (CNEOS) has classified more than 27,000 near-Earth asteroids, as of August 15. CNEOS says that around 1,000 of these near-Earth asteroids are larger than 3,280 in diameter. As for 2016 AJ193, its orbit calculates to a fly-by Earth around every six years. CNEOS states on its website that "the threat to any one person from auto accidents, disease, other natural disasters and a variety of other problems is much higher than the threat from NEOs (Near Earth Objects)."

NASA has discovered something that they have overlooked about the Milky Way galaxy, the galaxy we live in.

Due to Earth's position in the Milky Way galaxy, researchers have a difficult time discovering new things about the galaxy, but that doesn't mean it never happens. According to a new study published by NASA, the Milky Way galaxy is a spiral galaxy, and one of its spiral arms has a "break" in it, much like a splinter protruding from a piece of wood.

NASA researchers used data acquired from the European Space Agency's Gaia mission and found that the broken arm spans around 3,000 light-years. The location of the break in the spiral arm contains some of our galaxy's most incredible spectacles, such as the Pillars of Creation, Omega, Lagoon, and Trifid nebulae.

Researchers have uncovered an ancient tomb in Pompeii, revealing what is now considered the best-preserved human remains from the tragic disaster.

In 79 A.D, the Roman city of Pompeii was covered in volcanic ash, and the air was polluted with toxic gas as the neighboring volcano Mount Vesuvius erupted. The entire city was buried under ash from the eruption, preserving many parts of it for thousands of years. Now, archaeologists have turned it into a large archaeological site. According to reports, one recently conducted dig uncovered human remains from inside a tomb within the Porta Sarno necropolis.

The preserved human was a man named Marcus Venerius Secundio, and his skeleton was clearly in remarkable shape as the skull still has some strands of white hair as well as an intact ear. The location of where the tomb was found holds significance as it was in what was once considered a prestigious part of the city, the main eastern entrance.

Researchers are getting better and better at spotting exoplanets, and now according to Brazilian researchers, an instrument is on the verge of discovering an Earth "twin".

The study was published in the Astronomical Journal and explored how a new spectrograph called Espresso that was installed Very Large Telescope located in Chile could discover exoplanets that have a similar mass to Earth and are orbiting a star similar to how Earth is orbiting the Sun. The group of researchers observed a star named HIP 11915 for 60 nights. The star is located 175 light-years from Earth, and the reason the researchers chose this star is because it has a planet that is analogous to Jupiter.

The researchers were able to acquire reliable measurements of the radial velocity. However, to confirm their findings, the researchers need to observe the exoplanet complete one full orbit around its local star. By measuring the radio velocity of exoplanets, researchers are able to determine the inclination of the planet's orbit around its local star, which then allows them to determine the mass of the planet.
