A Strange Asteroid-comet Could Be Key To Understanding The Birth Of The Solar System

More details: Visit website

That is, of course, quite an intriguing possibility. Chiron is just one of a thousand centaurs that we currently know of. Many of them are believed to have originated out beyond the frozen realm of Neptune. However, they would have later moved into the solar system following gravitational resonances with their orbits and Neptune.

But how exactly does this asteroid-comet hybrid tell us more about the birth of the solar system? Well, according to new observations made by the James Webb Space Telescope , Chiron appears to have a composition of surface ices that are unlike any astronomers have found on any other centaur thus far.

None of the ices are ⁘unusual,⁘ per se. However, the combination of ices and gases found together on Chiron is what makes everything so intriguing. Further, the fact that, despite never climbing above -220 degrees Fahrenheit (-140 degrees Celsius), the ices on Chiron actually sublimate.

What this means, is that the sun⁘s radiation causes some interesting chemical reactions when it interacts with the ices found on the asteroid-comet hybrid, spurring on the production of organic byproducts like ethane, propane, and various carbon dioxide.

Researchers say that discovering which of these gases is actually part of the object⁘s coma will help them learn more about the chemical and physical properties of the rock, as well as the thickness and porosity of the ice layer and how the irradiation is affecting it.

Of course, learning more about that is going to take some time. Chiron is a long way away from us, and while its orbit will bring it just inside the orbit of Saturn, it won⁘t get that close for another 20 years. Luckily, it will continue to get brighter and more active as it gets closer to the sun, giving astronomers more opportunities to observe it.

As a piece of spaceborne garbage veered toward the International Space Station in November, the seven astronauts on board braced themselves.

A Russian spacecraft attached to the space station lit its engines for five minutes, slightly tweaking the station's trajectory and moving the football field-size laboratory out of harm's way. If the space station had not changed course, the debris could have passed within 2 ½ miles (4 kilometers) of its orbital path, according to NASA .

Debris striking the space station could have spelled disaster. An impact might have depressurized segments of the station and left the astronauts scrambling to return home.

What's more concerning: The potential strike was not all that rare of an occurrence. The International Space Station has had to make similar maneuvers dozens of times since it was first occupied in November 2000, and collision risks are growing every year as the number of objects in orbit around Earth proliferate.

For years , space traffic experts have raised alarm bells about the increasing congestion. Earlier collisions, explosions and weapons tests have resulted in tens of thousands of pieces of debris that experts are tracking and possibly millions more that cannot be seen with current technology.

And while risks to astronauts may be a top concern, congestion in orbit is also hazardous to satellites and space-based technologies that power our everyday lives — including GPS tools as well as some broadband, high-speed internet and television services.

"The number of objects in space that we have launched in the last four years has increased exponentially," said Dr. Vishnu Reddy, a professor of planetary sciences at the University of Arizona in Tucson. "So we are heading towards the situation that we are always dreading."

Named for American astrophysicist Donald Kessler and based on his 1978 academic paper , Kessler Syndrome — as the term is used today — has a muddy definition .

NEW YORK — Scientists have spotted what appear to be two stars whipping around each other near the black hole at the center of our Milky Way galaxy.

Nearly every large galaxy has a supermassive black hole at its heart. The one in the middle of the Milky Way, called Sagittarius A (with an asterisk denoting star), is about 4 million times more massive than our sun and is relatively quiet, occasionally swallowing gas or dust that comes its way.

Scientists know stars can form near and even orbit these black hole behemoths, but they've never seen a pair of stars survive so close by.

The celestial sighting is unusual, and more research is needed to be certain of what the objects are, said astrophysicist Anna Ciurlo with the University of California Los Angeles.

At about 2.7 million years old, the twin stars seem to be fairly young. Scientists said they appear to orbit each other at just the right distance: If they were too spread out, the black hole's gravity would rip them apart. Any closer, and they'd merge into a single star.

Scientists Still Don't Fully Understand Why Some Planets Have Hundreds Of Moons While Others Have...

Headlines:

On Earth, you can look up at night and see the Moon shining bright from hundreds of thousands of miles away. But if you went to Venus, that wouldn't be the case. Not every planet has a moon ⁘ so why do some planets have several moons, while others have none?

I'm a physics instructor who has followed the current theories that describe why some planets have moons and some don't.

First, a moon is called a natural satellite. Astronomers refer to satellites as objects in space that orbit larger bodies. Since a moon isn't human-made, it's a natural satellite.

Currently, there are two main theories for why some planets have moons. Moons are either gravitationally captured if they are within what's called a planet's Hill sphere radius , or they're formed along with a solar system .

Objects exert a gravitational force of attraction on other nearby objects. The larger the object is, the greater the force of attraction.

The first thing Hansjürgen Köhler insists on clarifying as we begin our conversation is that at his place of work, the Central Research Network for Extraordinary Celestial Phenomena (CENAP), they don't believe aliens are lurking somewhere on Earth.

⁘We differ from the ufologists, who claim that there is an extraterrestrial presence on Earth,⁘ says Köhler, the founder and director of Germany's UFO registration office CENAP.

⁘This is completely unfounded and also goes against our experience in over 50 years of active case investigations,⁘ Köhler says.

According to its director, CENAP has processed more than 11,000 reports of unusual celestial sightings to date, analysing hundreds of photos and videos that could be attributed to natural and earthly causes.

While there are currently 119 unsolved cases, there's no reason to engage in speculation, Köhler says. The problem with those cases is that they miss key data like the date, time or location of the sighting.

For all those immediately thinking of aliens, Köhler reminds us of the meaning of the acronym UFO: unidentified flying object.

He founded CENAP as a ⁘point of contact for all those who want an explanation for a phenomenon they observed and didn't understand.⁘

The organization, founded in 1976, is supported by the European Space Agency (ESA) and Germany's air traffic control company DFS.

The broadcast and orbits would go on to be a milestone in both media and space history. At the time, it was the most watched television broadcast in history. According to Borman , the crew was told that they would have "the largest audience that had ever listened to a human voice". NASA simply instructed the astronauts to say something appropriate . As they beamed back images of the moon and Earth, the astronauts took turns reading from the book of Genesis.

That same Christmas Eve, Anders snapped the famous Earthrise photo showing what our home looks like from the moon's orbit.

Apollo 8 launched from Cape Kennedy Air Force Station in Florida on December 21, 1968 . It was the first crewed spacecraft to leave Earth's gravitational sphere of influence and also the first human spaceflight to reach the Moon.

It took 68 hours for the spacecraft to reach the moon. The crew then orbited 10 times over about 20 hours, during which they made the famous Christmas Eve broadcast.

The next morning, mission control waited for confirmation that Apollo 8's engine burn to leave lunar orbit was successful. Lovell radioed back "Roger, please be informed there is a Santa Claus," and the crew began the journey home.

TRENTON, NJ – New Jersey's skies have seen their fair share of mysterious objects, with drone sightings becoming a hot topic of conversation. Whether it's someone piloting a recreational drone for fun or law enforcement using them for surveillance, these buzzing machines have sparked curiosity and sometimes confusion.

Many reports of blinking lights or unusual movements turn out to be drones, as their technology allows them to hover, zip, and even perform acrobatics that can mimic something otherworldly.

But not everything you see up there is a drone. The night sky over the Garden State is teeming with natural wonders like stars, planets, and meteors that can easily be mistaken for human-made objects. For instance, Venus—the so-called "Evening Star"—often gleams so brightly that people confuse it for a hovering aircraft or drone. Similarly, planes passing through Newark Liberty International Airport add their own set of moving lights, further complicating what's visible in the sky. The combination of celestial phenomena, atmospheric conditions, and human activity makes the night sky a kaleidoscope of potential misinterpretations.

It's also worth noting that many drone sightings are debunked upon closer inspection. A flickering light could be an airplane at a distance, a shooting star, or even an optical illusion caused by a camera lens. Amateur astronomers often point out how mistaken identity plays a huge role in what people think they're seeing. While drones are increasingly present in our airspace, they're just one part of the dazzling and complex tapestry above New Jersey.

As winter nights envelop New Jersey, the sky transforms into a celestial theater, showcasing planets, stars, and human-made wonders. Let's explore the nightly spectacles awaiting you and how to enhance your stargazing experience.

December 2024 offers a dazzling lineup of planets visible from the Garden State. Here's when and where to spot them:

UFO Expert Who Claims To Have Discovered Alien Invasion Portal On Earth Gives Chilling Warning To...

Image More details: Found here

A UFO expert has shared a chilling prediction about the possibility of an alien invasion after a series of mystery drone sightings over various military bases.

The ears of paranormal enthusiasts, ufologists and conspiracy theorists worldwide pricked up over the past couple of days amid reports of various unexplained drone sightings in the US, UK and Germany over the past couple of days.

The sightings, which have occurred at various US Air Force bases, have managed to cause so much panic that President Biden has been forced to intervene, with a joint statement from the FBI and the US Department of Homeland Security also stating there was 'no evidence' the sightings in New Jersey 'pose a national security or public safety threat'.

One person who's keen to point to a more extraterrestrial explanation is Carl Nally, UFO and Paranormal Research Ireland (UPRI) co-founder and. co-author of various paranormal books , who believes the sightings are a warning for what's about to come.

⁘It's an amazing situation, the way we see it,⁘ Nally explained in a recent interview with The Irish Mirror.

⁘You would imagine that, when anything appears over a military base, a military helicopter would go up and investigate them but they haven't done that.

An official for the Department of Defence stated that while there is no suggestion 'malicious intent' in regards to the mysterious sightings, they 'don't know' the origin.

Nally has also shared his belief that aliens are able to quickly enter and exit Earth's atmosphere via a series of 'portals', with one of these being situation between the Irish towns of Athlone and Slane.
