The comet that rambled past us from another star last year likely originated in a cold, isolated corner of the galaxy that had yet to gel into its own solar system, astronomers reported Thursday.

Comet 3I/Atlas is only the third interstellar visitor to be confirmed and quite possibly the oldest. Scientists estimate it could be up to 11 billion years old, more than twice as old as the sun.

A team led by the University of Michigan used the ALMA observatory in Chile’s Atacama Desert to examine the comet last fall. The errant but harmless iceball was discovered last summer, giving NASA and the European Space Agency plenty of time to aim multiple space telescopes at it as it zoomed past Mars in October and made its closest approach to Earth in December. It's now well past Jupiter on its way out of our solar system for good, still visible only to the professionals.

In the study, scientists said they detected extremely high amounts of deuterium, or heavy hydrogen, in the comet's water. That suggests that the comet originated in a place considerably colder — before the star of this solar system even formed — than our own cosmic neighborhood, said the University of Michigan's Teresa Paneque-Carreno.

While our sun may have been surrounded by other newborn stars as it was forming, she noted, this comet's home star could have been more of a loner, leading to less heating and colder conditions.

The findings were published in Nature Astronomy.

The comet's precise place of origin is still unknown. Observations by the Hubble Space Telescope put the size of its nucleus somewhere between a quarter-mile and 3.5 miles (440 meters and 5.6 kilometers). It's hurtling away at 137,000 mph (220,000 kph).

Linking all these “puzzle pieces together may give an idea to how the planet-forming conditions were at these early times,” the Associated Press quoted Paneque-Carreno as saying in an email.

The first known interstellar object to stray into our celestial backyard — Oumuamua — was discovered by a telescope in Hawaii in 2017. Comet 2I/Borisov followed in 2019, named for the Crimean amateur astronomer who first spotted it.

Why Do People Lie? 8 Tips for Dealing With Someone Who Isn't Telling the Truth

People sometimes tell lies in everyday situations, not necessarily to deceive or hurt others, but to spare their feelings and preserve relationships. You might, for example, pretend to like a gift you've received even though you don't actually care for it. These small, relatively harmless untruths are commonly known as "white lies," according to Everyday Health.

But not all lies are equally serious. Being less than honest about an unflattering haircut is very different from concealing an affair. Still, discovering that someone you care about may be hiding the truth can be emotionally unsettling, no matter how insignificant the lie might seem.

Why Do People Lie?

Lying is a complex social behavior driven by a range of motivations, says Laura Sgro, a Los Angeles-based therapist. It exists on a spectrum, from relatively harmless dishonesty to deception that can have devastating consequences.

Sgro explains that although a person's intentions do not erase the consequences of their actions, understanding why someone lied, along with what you know about that person and the circumstances, can help put the situation into perspective.

Researchers generally distinguish between two main categories of lies: those intended to protect relationships and those intended to protect oneself.

The first category, known as "other-oriented lies," is intended to preserve relationships, while the second, "self-oriented lies," often has more harmful consequences.

Other-oriented lies, commonly described as white lies, are widespread in social relationships. An example would be telling a friend you loved a gift they gave you when you actually didn't.

According to Sgro, these lies are usually intended to spare another person's feelings or benefit them in some way, and often stem from good intentions.

Self-oriented lies, by contrast, are intended to manipulate circumstances for personal gain, such as inventing a story to conceal wrongdoing.

Sgro says the motivation behind this kind of deception is considerably less selfless. Even when these lies go undetected, they can weaken social connections, partly because people who lie are more likely to assume that others are dishonest as well.

Another form of dishonesty is compulsive or pathological lying, characterized by telling five or more lies a day.

This behavior is often associated with personality disorders, including narcissistic personality disorder and antisocial personality disorder, although it can also occur as a distinct condition.

Estimates suggest that pathological lying affects between 8% and 13% of the general population.

8 Tips for Dealing With Someone Who Lies to You

When you believe someone has lied to you, feeling hurt or betrayed is a natural response. Before confronting them, however, therapists recommend several strategies for handling the situation.

Consider the Source

Jordan A. Conrad, PhD, a licensed clinical social worker and therapist based in New York City, explains that when facts don't add up, your first instinct may be to assume that someone deliberately lied to hurt you, prompting an immediate confrontation. Before reacting, however, consider your relationship with that person.

Conrad advises tailoring your response to the individual's character and behavior. A close friend who has consistently supported you deserves a different response from a coworker who routinely belittles you.

Examine Your Own Reactions

Conrad recommends asking yourself a question: How would I have reacted if this person had told me the truth?

This applies to relatively harmless lies, such as someone complimenting a haircut they don't actually like, as well as more serious situations, such as a friend encouraging you to make a bold career move despite privately believing it is a bad idea.

Conrad warns that if you react angrily whenever a friend tells you something you don't want to hear, you should not be surprised if people eventually begin withholding details or even lying to you.

He emphasizes the importance of being honest with yourself about the expectations you place on others.

Document the Evidence

Gaslighting is a form of psychological manipulation that causes someone to question their memory or perception of events.

If you believe you are experiencing this kind of manipulation, writing down your account of what happened and preserving supporting evidence can help you maintain a clear understanding of the situation.

Sgro explains that some people are particularly skilled at undermining another person's sense of reality, making documentation a valuable way to remain grounded in your own recollection and perspective.

Prepare Before Confronting Someone

Before confronting someone you believe has lied to you, identify the main points you want to address and practice expressing them aloud.

Sgro notes that heightened emotions can make it easy to lose focus or allow a conversation to drift away from its original purpose.

Rehearsing what you want to say can help you remain composed and focused on what you hope to achieve.

Show Compassion and Allow Room for Explanation

Remember that what appears to be dishonesty could simply be a misunderstanding rather than a deliberate lie.

If you decide to confront the person, approach the conversation in good faith and give them an opportunity to explain their perspective.

Conrad recommends explaining how you discovered the apparent lie and asking the other person for their account of what happened.

He stresses that serious accusations should be supported by substantial evidence.

Remain Calm and Composed

Even when confronted with a significant lie, try to remain calm throughout the conversation.

The aim is to avoid reacting in a way that leaves you feeling disappointed in yourself afterward.

Conrad emphasizes that your feelings are legitimate and that you have every right to express them. However, becoming overwhelmed or behaving in a way you may later regret is unlikely to help resolve the situation.

Communicate Your Boundaries Clearly

Establishing personal boundaries is essential in any relationship, particularly one in which trust has been damaged by dishonesty.

Sgro explains that setting boundaries does not mean telling others how they must behave, because you cannot control or change another person's actions.

Instead, it means clearly communicating your expectations and explaining what the consequences will be if those boundaries are not respected.

Give Yourself Time to Recover

Lies range from minor white lies to the concealment of important truths, and people's emotional responses can vary just as widely.

You may feel irritated, deeply hurt or profoundly shaken.

Give yourself enough time to understand and process those emotions, whether by writing down your thoughts or discussing what happened with someone you trust.

A serious betrayal, such as an affair, may require considerably more time to come to terms with and to organize your thoughts.

Sgro advises that when dishonesty leaves you questioning your sense of reality, engaging in activities you enjoy can help you reconnect with yourself.

She also recommends grounding techniques, including deep breathing exercises, to help calm the nervous system.


India Vows Action after 1st Cheetah Shot Dead

India has vowed "swift action" after a cheetah was shot dead, the first such killing since the country began reintroducing the animals in 2022, the government said Wednesday.

The environment ministry said it had ordered a "high-level team for an on-ground investigation" into the shooting of the 19-month-old male, treating the incident with "utmost gravity”

The India-born cheetah -- whose mother was among those introduced to India from Botswana, Namibia and South Africa as part of efforts to restore the planet's fastest land animal -- was shot as it prowled in forests outside a protected national park.

Asiatic cheetahs were declared extinct in India in 1952. The critically endangered subspecies, once found across the Middle East, Central Asia and India, now survives in very small numbers in Iran.

Their African cousins were first reintroduced in September 2022 to India, to the Kuno National Park, 300 kilometers south of New Delhi.

The wounded cheetah was picked up on Sunday in forests in Madhya Pradesh state, outside Kuno's boundaries, and taken for veterinary care.

"During the surgery, five firearm pellets were recovered from its body," the environment ministry said.

Despite efforts, the cheetah died on Tuesday, AFP reported.

"Medical examinations corroborated multiple internal injuries associated with the recovered firearm pellets," it added.

The high-profile project, championed by Prime Minister Narendra Modi, has been dogged by criticism over the deaths of several of the cats.

But experts in animal reintroductions say they often result in more than 50 percent mortality, especially in the initial phases.

The National Tiger Conservation Authority, which oversees the cheetah project, said that survival rates and hunting successes are "comparable to other international cheetah reintroduction efforts, with recorded wild prey kills confirming successful adaptation to the Indian landscape.”

The total cheetah population in the wild in India is around 60, including some 40 Indian-born cheetahs.


Philippine Island Fights Rising Seas with Nature, Not Concrete

For years, residents of a flood-prone Philippine island north of Manila have elevated their homes atop layer upon layer of concrete, only to see floodwaters threaten them again.

Burdened by strong storm surges, land subsidence and rising seas exacerbated by climate change, the 3,000 residents of tiny Pamarawan Island have turned to bamboo poles and discarded oyster shells to build a barrier aimed at weakening waves and managing floods.

The unusual approach offers a nature-based alternative for a country still grappling with a multibillion-dollar scandal that drove public fury over substandard -- and at times non-existent -- concrete flood-control projects.

"We were terrified whenever there were typhoons. We couldn't sleep at night," fisherman Edgar Javier told AFP on a recent visit, recalling how strong waves once brought down one of his home's concrete walls.

"Whenever the waves hit, the wall shakes."

The project began when the city government of Malolos, home to the island, launched a study with a Dutch engineering consultancy.

"(Concrete infrastructure) projects won't suffice," Mayor Christian Natividad told AFP.

While the project, the first of its kind in the country, initially faced resistance from officials and residents working without a blueprint, Natividad said they had "nothing to lose".

"It's like you accept daily flooding or you do something else with risk," he said.

"I chose risk."

- Slowing the waves -

By May last year, workers, many of them residents, had begun installing bamboo poles packed with brushwood along the coast. They are designed to slow water flow and trap sediment, with the goal of gradually raising the seabed and supporting mangrove growth.

When AFP journalists visited the site, workers were building an oyster-shell breakwater about 100 meters (330 feet) offshore.

Under the searing heat, men in caps pounded wooden stakes used to secure coconut-fiber bags filled with shells on an artificial shore first created with sea sand.

"This breakwater's main purpose is to lessen the impact of the wave before it can reach the community," project manager Lyana Galang told AFP, adding that the oyster-shell barriers work in concert with bamboo sediment traps.

Filipino scientist Antonio Contreras said the Philippines had long relied heavily on concrete dykes and seawalls, many undertaken without adequate study.

"We have altered the environment so much that we tend to work against nature when in fact we should work with it," Contreras told AFP, noting that some design flaws linked to corruption had cost lives.

But nature-based solutions were not a universal answer, he warned, particularly during catastrophic floods, and should complement conventional infrastructure.

Contreras said the approach in Pamarawan could be replicated elsewhere, provided local environmental conditions were carefully taken into account.

Bamboo and oyster shells also need to be sourced sustainably, he warned, as bamboo deteriorates over time and releases carbon as it decomposes.

The nature-based installations, which cover about 14 hectares along Manila Bay, cost 70 million pesos ($1.1 million), including maintenance, compared with around 90 million pesos for a concrete seawall, Mayor Natividad said.

He estimated bamboo will need to be replaced once every five years.

- 'Our feet are dry' -

With its first phase completed in late 2025, the installation has already brought some comfort to residents.

Fisherman Edgar Javier said the breakwaters had softened waves and helped keep floodwaters at bay during typhoons and monsoon rains this year.

"This has made a huge difference for us. We can still feel the waves, but they have significantly weakened. (They're) almost nothing now," he said.

Arsenia Cabigao, 58, said flooding had previously disrupted her livelihood by submerging areas where she dried fish.

"Our feet are dry at last. They weren't before," she told AFP as she sliced small fish in a narrow Pamarawan alley.

The project's long-term effectiveness remains uncertain, with a scientific assessment due next year to determine if mangrove planting can begin, Natividad said.

Its success, he added, would become more tangible over the next decade as accumulated sediment stabilized the seabed and allowed for the growth of mangroves, which would provide another natural barrier.

Vince Dizon, head of the public works department before a recent reassignment, said he hoped the Pamarawan project could be replicated in other flood-prone areas.

"We need to study this, and learn from those who know and have already done this correctly, so we won't waste public funds again," Dizon told reporters on a visit to the island.

For residents who fear being driven from their longtime home, the ultimate test will be whether their houses remain upright when typhoons and monsoon rains strike.

"It's hard to fight water. Now we're trying to live with water," Natividad told AFP.

"We're building with nature."
