Hang onto your chair and prepare to have your mind blown.. New research reveals that a big portion of the Earth’s water is older than previously thought, and actually predates the age of the Sun. Moreover, the findings of the study suggest that water – and life – could exist on exoplanets throughout our galaxy and beyond.
That bottle of water sitting on your desk is really really old.. Actually, unfathomably ancient..
“This is an important step forward in our quest to find out if life exists on other planets,” said Professor Tim Harries of the University of Exeter, a member of the research team. “We know that water is vital for the evolution of life on Earth, but it was possible that the Earth’s water originated in the specific conditions of the early solar system, and that those circumstances might occur infrequently elsewhere.”
The findings increase the chances that water is present on other planets. The study confirms that the way in which our solar system was formed is not unique, which means that the same conditions – and therefore life – likely exists elsewhere in our galaxy. It is an amazing finding, given the fact that approximately 2,000 exoplanets have been discovered so far, and no one knows how many of them may still be waiting to be discovered. According to the estimations, each star in the Milky Way galaxy hosts at least one planet.
It is worth noting that water is not an exclusive privilege of our planet. In fact, much evidence of it can be found throughout our solar system. In particular, water ice is present on comets and asteroids, as well as on other planets of our solar system and their moons, such as Jupiter’s Europa or Saturn’s Enceladus.
The prevailing theory in modern cosmology suggests that water came from the solar nebula, or the so-called protoplanetary disc, a cloud of dust and gas surrounding the forming Sun. Now, researchers from the University of Michigan led by astronomy PhD student Ilse Cleeves decided to find out whether the water was already present in the sun’s protoplanetary disc, or whether it was formed with the birth of the Solar System.
“If water in the early Solar System was primarily inherited as ice from interstellar space, then it is likely that similar ices, along with the prebiotic organic matter that they contain, are abundant in most or all protoplanetary disks around forming stars,” said co-author of the study Conel Alexander of the Carnegie Institute.
“But if the early Solar System’s water was largely the result of local chemical processing during the Sun’s birth, then it is possible that the abundance of water varies considerably in forming planetary systems, which would obviously have implications for the potential for the emergence of life elsewhere.”
To figure out where the water was formed, the researchers simulated a model with two kinds of frozen water – regular hydrogen based water, and so-called “heavy water” containing the hydrogen isotope deuterium, which can be found on comets, meteorites and in the Earth’s oceans.
To recreate the conditions of the solar system’s formation, the scientists simulated a solar nebula without frozen heavy water, in order to find out whether the solar system was able to generate the ratios of deuterium from chemical reactions in the nebula. As a result, it was discovered that the system couldn’t produce heavy water; therefore it must have already existed in the sun’s protoplanetary disk.
According to the results of the simulation, 30 to 50 per cent of the water originated in the solar nebula, which means that it is nearly a million years older than our solar system.
“Our findings show that a significant fraction of our Solar System’s water, the most-fundamental ingredient to fostering life, is older than the Sun, which indicates that abundant, organic-rich interstellar ices should probably be found in all young planetary systems,” concluded Alexander.
The findings add to a plethora of evidence that water and therefore life is not exclusive to our planet.. a paradigm shift in the way we see the universe indeed.

WATCH: Video Shows Bullets Fly as Armored Car Crew Narrowly Escapes Brutal Heist
Dramatic dash cam footage from Pretoria, South Africa, shows the moment that the crew of an armored car narrowly escaped an attempt by armed robes to stage a heist.
The shocking video shows a pair of private security officers transporting cash in a bulletproof Toyota truck on April 22 before they suddenly come under attack by armed assailants.
For the first minute of the roughly three-minute-long video, the security guards can be seen routinely driving down a highway.
The vehicle then comes under fire as bullets can be heard slamming into the driver side of the car, with the window by the driver’s side shattering.
The driver, who maintains his calm and composure during the attack, manages to escape amid the traffic. He also seems to slam into one of the two vehicles belonging to the attackers.
“They’re going to shoot. They’re going to f**king shoot,” the driver then says, urging his colleague to pull out the rifle and prepare to defend their lives.
As gunshots continue to ring out, the two drive silently as the tension builds. The driver then shouts to his colleague: “Phone Robbie, phone Josh! Ask them where they are.”
As the video ends, the driver can be seen stopping the vehicle and grabbing his colleague’s rifle. At that point, it becomes clear that the assailants have realized that their attack was futile they had already fled the scene.
“The suspects fired several shots at the [Cash-In-Transit] vehicle in an attempt to stop it during a high-speed chase,” said police spokesperson Brigadier Vishnu Naidoo , reports News24.
“The driver of the CIT vehicle managed to evade the robbers for a while but later stopped in wait for the robbers,” Naidoo added. “The robbers fled without taking any money. No arrests have yet been made.”
Online users have praised the steel nerves of the armored car’s crew in navigating what could have been a deadly attack.
After Strong Backlash, NYPD Kicks Robotic Dog “Spot” to the Curb
The New York City Police Department decided this week to stop leasing a robotic dog from Boston Dynamics following a sustained outcry from residents and lawmakers, who denounced the use of the high-tech, four-legged device in low-income neighborhoods as a misallocation of public resources and violation of civil liberties.
When the NYPD acquired the K-9 machine last August, officials portrayed “Digidog”—the department’s name for the camera-equipped, 70-pound robot—as “a futuristic tool that could go places that were too dangerous to send officers,” the New York Times reported earlier this week.
Inspector Frank Digiacomo of the department’s Technical Assistance Response Unit said in a television interview in December: “This dog is going to save lives. It’s going to protect people. It’s going to protect officers.”
Instead—thanks to strong backlash from critics, including people who live in the Bronx apartment complex and the Manhattan public housing building where the robotic dog was deployed in recent weeks—the department is returning “Spot,” as Boston Dynamics calls the device, months earlier than expected.
According to the Times:
In response to a subpoena from City Councilman Ben Kallos and Council Speaker Corey Johnson requesting records related to the device, police officials said that a contract worth roughly $94,000 to lease the robotic dog from its maker, Boston Dynamics, had been terminated on April 22.
John Miller, the police department’s deputy commissioner for intelligence and counterterrorism, confirmed on Wednesday that the contract had been canceled and that the dog had been returned to Boston Dynamics or would be soon.
Miller told the Times that the police had initially planned to continue testing the K-9 machine’s capabilities until August, when the lease had been scheduled to end.
“Robotic surveillance ground drones are being deployed for testing on low-income communities of color with under-resourced schools,” Rep. Alexandria Ocasio-Cortez (D-N.Y.) tweeted in response. “Please ask yourself: when was the last time you saw next-generation, world class technology for education, healthcare, housing, etc. consistently prioritized for underserved communities like this?”
And earlier this month, as Common Dreams reported, footage of the robotic dog walking through a Manhattan public housing building went viral, sparking additional outrage and prompting a city council investigation.
“Why the hell do we need robot police dogs?” Rep. Jamaal Bowman (D-N.Y.) asked at the time.
While there are “people living in poverty, struggling to put food on the table, keep a roof over their head, take care of their kids, afford child care—all this going on, and now we got damn robot police dogs walking down the street,” Bowman lamented.
Bill Neidhardt, a spokesperson for New York City Mayor Bill de Blasio, who urged the police department to reconsider its use of the robot following objections from residents and lawmakers, said he was “glad the Digidog was put down.”
“It’s creepy, alienating, and sends the wrong message to New Yorkers,” Neidhardt said.

Senate Intelligence Leaders Say Mystery “Sonic Weapon” Attacks on U.S. Officials Increasing
After it was revealed Thursday that US intelligence is investigating at least two potential “directed energy” sonic attacks on White House personnel – one of which is alleged to have happened just off White House grounds – the US Senate Intelligence Committee weighed in on Friday, saying such mysterious incidents appear to be happening with greater frequency worldwide.
Senators Mark Warner (D) and Marco Rubio (R) agreed that such microwave energy attacks have gone on for “nearly five years” and have targeted “US government personnel in Havana, Cuba and elsewhere around the world.” In a joint statement the two ranking members said, “This pattern of attacking our fellow citizens serving our government appears to be increasing. The Senate Intelligence Committee intends to get to the bottom of this,” according to Reuters.
As with the late 2016 into 2017 ‘Havana Syndrome’ attacks in which some 50 diplomatic personnel reported experiencing strange symptoms from vomiting to concussions to extreme nausea to chronic headaches, which was believed the result of some kind of undetected ‘directed energy’ weapon, the most recent incidents saw media reports speculate that Russia or China might be behind them.
It was starting last week that the mysterious incidents returned to national media spotlight after defense officials said they believe Russia is likely behind microwave energy weapon attacks on US troops in northeast Syria. Apparently some US troops occupying the country began reporting”flu-like symptoms” which caused the DoD to investigate possible linkage to microwave or directed energy weapons on the battlefield of Syria. Politico reported that “officials identified Russia as a likely culprit, according to two people with direct knowledge of the matter.”
Despite instances of strange symptoms and even head injuries experienced by diplomatic personnel or troops abroad, no “energy weapon” has ever been found or uncovered that’s believed to have caused any of these alleged attacks. Most often US personnel report the symptoms enough time after the alleged attack took place for the “plot” and culprit to remain undetected. Naturally this has resulted in immense skepticism and pushback.
One deeply critical response to all the reporting late this week quipped: “Another day, another mostly anonymously sourced story about unidentified assailants supposedly assaulting U.S. government employees around the globe. This time, according to CNN, federal agencies are looking into something closer to home: symptoms suffered by a White House employee in Virginia and National Security Council staffer near the south lawn of the White House.”
“Although a government report later concluded the most likely cause was instead some sort of ‘directed, pulsed radiofrequency energy’ (i.e. a microwave weapon), that conclusion was primarily based on a lack of evidence for other causes and received strong pushback from many others in the scientific community.”
The commentary in Gizmodo pointed out further that “No hard evidence of any kind for the technology has ever been publicly presented by the US government. Reports citing government officials who suspect Russian intelligence to be involved have largely been anonymous and buoyed primarily by rumors the Russian government may have resumed Soviet-era research into experimental weapons.”
