‘Spiders’ on Mars? NASA scientists recreate mysterious Red Planet formations

(NEW YORK) — Over two decades since NASA researchers first saw images of mysterious, spider-like formations across the southern hemisphere of Mars, the space agency announced it’s recreated the planet’s “spiders” here on Earth.
Dubbed “araneiform terrain,” the formations span over a half-mile long and have hundreds of branches that resemble spider legs, according to NASA.
Theories surrounding the Red Planet’s “spiders” date back to 2003, when researchers got a glimpse of the terrain via Mars orbiters, with many believing they are formed through carbon dioxide ice, which doesn’t occur naturally on Earth.
To confirm this hypothesis, researchers from NASA’s Jet Propulsion Laboratory (JPL) in Southern California said they recreated the formation process in a simulated Mars environment that mimicked the planet’s air pressure and temperature.
The simulation chamber — called the Dirty Under-vacuum Simulation Testbed for Icy Environments, or DUSTIE for short — uses liquid nitrogen to reach temperatures as low as minus 301 degrees Fahrenheit, according to NASA.
Results from the five-year study were published this month in The Planetary Science Journal.
“The spiders are strange, beautiful geologic features in their own right,” JPL researcher Lauren Mc Keown said in a Sept. 11 press release. “These experiments will help tune our models for how they form.”
Researchers found that when sunlight heats soil underneath slabs of carbon dioxide ice that form on the surface of Mars each winter, the soil absorbs the heat and causes the ice closest to it to turn directly into carbon dioxide gas, according to NASA.
This process, called “sublimation,” causes the ice to crack and brings dust and soil to the surface of the ice, according to the agency.
“When winter turns to spring and the remaining ice sublimates, according to the theory, the spiderlike scars from those small eruptions are what’s left behind,” researchers wrote in the study.
To recreate the formation process in DUSTIE, researchers said they analyzed simulated Mars soil that was contained and submerged into a liquid nitrogen bath.
Matching the reduced air pressure to match that of Mars’ southern hemisphere, researchers said they watched as carbon dioxide gas then flowed into the chamber and condensed into ice over a period of three to five hours.
Researchers then placed a heater inside the chamber below the simulated soil to warm it up and crack the ice.
Mc Keown said she was “ecstatic” when the theories were proven by seeing a carbon dioxide gas plume erupt from within the Mars soil simulation.
Lab experiments and orbiter images are the closest look NASA has at these unique Martian spiders, with the Curiosity and Perseverance rovers exploring far from the region where they occur.
So far, a spacecraft has yet to land on the Red Planet’s southern hemisphere.
(LONDON) — As a 4-year-old Palestinian child waited on Sunday to cross into Jordan for a chance at a life-saving medical procedure, a gunman was crossing from the other side to attack Israeli border guards.
Accompanied by his mother and fiercest advocate, Huda, Ahmed Hammad had left Gaza a few hours earlier for an emergency surgery to change his pacemaker, a necessary device he had since he was just a baby that has a battery that is now days away from completely depleting.
As doctors first warned about the situation in March, the family soon organized to request an emergency evacuation, according to the humanitarian agents helping them. But Hammad’s case was repeatedly rejected by Israeli officials who cited security concerns, they said.
Until Sunday, when he made it out of Gaza for the first time, traveling to the crossing in the West Bank, just to be returned to the war-torn Gaza Strip a few hours later. All crossings from Jordan were shut down after the gunman coming from Jordan killed three Israeli civilians at Allenby Bridge crossing, Israeli officials said.
It has been over 11 months since Hamas militants carried out a surprise attack that prompted a retaliatory war from Israel, which has left over 41,000 killed and 94,000 injured in Gaza, according to the Hamas-controlled Gaza Health Ministry. The health care system in the Strip collapsed as a direct result, leaving cases like Hammad’s in a limbo of bureaucracy that quickly took most of the time he had left to save his life.
Humanitarian agencies, such as Save The Children and Doctors Without Borders, say there are thousands of other children like him waiting to evacuate for medical reasons.
Hammad, who is nonverbal, has people who raised their voice on his behalf, pleading his case to the relevant authorities more urgently as every day went by.
His mother, Huda, who said she already lost a daughter early in the war due to malnutrition and lack of health care, has been documenting Ahmed’s journey on Instagram.
In posts shared with a growing number of supporters from all around the world, Huda uploaded photos of her son resting in a tent, as well as videos of the frequent, painful seizure-like activity that came with his pacemaker’s battery dwindling.
Also fighting on behalf of Ahmed is Tareq Hailat, head of the Treatment Abroad Program at the Palestine Children’s Relief Fund (PCRF), which provides free medical care to Palestinian children who lack access to it.
“He needs to get out, or that battery runs out and he’s going to die,” Hailat told ABC News.
He added that surgeries like the one Hammad needs were ordinary in Gaza before Oct. 7 but are now impossible in what humanitarian agencies, such as Doctors Without Borders, call a destroyed health care system.
Hailat said that the situation with medical evacuations for children of Gaza deteriorated after the Israeli military took over the Philadelphi Corridor, a strategic ribbon of land running 9 miles at the border with Egypt that includes the Rafah crossing, a main evacuation point.
“Since the Rafah border has been closed, there’s only been about maybe a hundred children that have been pulled out. Before, we would pull out almost 50 every single day,” Hailat said.
When asked about the system in place and why emergency cases like Hammad’s can wait for months without updates, Hailat said there is no system in place and the permission appears to be given arbitrarily.
“We ask the same question every single day: why is this particular child not being able to be pulled out? And it really has to do with the fact that it’s all in the hands of COGAT and no one else,” Hailat told ABC News, referring to the Israeli military’s Coordinator of Government Activities in the Territories. “So we have to wait and plead until they approve, and we have to exert as much pressure as possible.”
Hammad’s peacemaker will soon lose power, which would leave him to face likely cardiac arrest, according to his doctor and advocates.
ABC News has reached out to COGAT for comment.
Dr. Oday Sallout, a cardiac and pediatric surgeon at the European Hospital in Gaza who has been following Hammad’s case, said he has a “complete heart block” condition, with his heart’s upper and lower chambers disassociated and not working in combination.
“This creates a mess, with complications including sudden loss of consciousness and ultimately the risk of cardiac arrest,” Sallout said in an interview. “With a pacemaker he can sustain a good life, but it must be changed. I’ve learned he was first approved to evacuate without his mother, which is like a death sentence for someone like Ahmed.”
He’s dependent on his mother, so separating them could be catastrophic, Sallout said.
After the Palestinian Ministry of Health flagged the case, Hammad was approved through the World Health Organization to be welcomed for treatment in multiple countries, including Spain and the United Arab Emirates.
(LONDON) — President Joe Biden will see out his term knowing that President-elect Donald Trump — a man he fought desperately hard to unseat in 2020 and called a “genuine danger to American security” — will succeed him.
Foreign policy has been central in Biden’s long political career. It will likewise form a major chunk of his legacy, as will the two wars — Russia’s invasion of Ukraine and the Middle East conflagration sparked by Hamas’ Oct. 7 attack — that erupted during his term.
Now less encumbered by political calculations — for himself or for Vice President Kamala Harris — and with only two months until Trump’s second inauguration, the outgoing president may have one last window to wield the power of the Oval Office in both theaters.
But with Trump looming above the outgoing Biden-Harris administration, American allies and enemies may be hesitant to engage with the outgoing administration.
European nations, for example, are already shifting focus to how best to court Trump, Leslie Vinjamuri of the British Chatham House think tank told ABC News.
“All these European leaders are very quickly reaching out,” she added. “They’re congratulating him. They want to talk with him. They want to work with him, because they understand that the stakes are extremely high and they clearly feel that by talking with him, they have an ability to influence policy and the outcome.”
“What they don’t want to do is to be seen to be making a deal with Joe Biden that undercuts whatever it is that Trump is going to do,” Vinjamuri added.
“It’s a very tricky position to be in, because if anything’s visible that cuts across what he wants to do, you as a leader risk being punished.”
Those at the top of American politics know that foreign policy success can accelerate careers and define legacies. Former President Richard Nixon infamously undermined President Lyndon B. Johnson’s efforts to negotiate an end to the Vietnam War during the 1968 election campaign for fear it would reduce his chances of victory.
Though he has already secured his second term, Trump appears unlikely to help the Biden administration with any foreign policy “wins” in its closing days.
“There’s a lot of uncertainty and room for maneuver — it’s highly unpredictable,” Vinjamuri said.
Russia and Ukraine
Russia’s war on Ukraine has dominated much of Biden’s presidency. He will leave office with Moscow’s forces holding large parts of Ukraine and still advancing, even if slowly and at huge cost.
“I think that now Biden can be much more decisive in support of Ukraine, especially when he sees that Trump will be the next president,” Oleksandr Merezhko — a member of Ukraine’s parliament and the chair of the body’s foreign affairs committee — told ABC News.
“Biden has his hands completely untied,” Merezhko added. “Now Biden is thinking about his legacy.”
“He might even try to take some decisions which will make irreversible changes in support of Ukraine — for example, he might lift all the restrictions on the use of the Western weapons on the territory of Russia,” Merezhko said. “And he might start the process of inviting Ukraine to join NATO.”
Merezkho acknowledged that progress on the NATO front might be ambitious. “Yes, he doesn’t have much time,” he said. “But he — with [National Security Adviser] Jake Sullivan and [Secretary of State] Antony Blinken — might do something creative to help Ukraine.”
It appears unlikely that Biden’s final months will bring Kyiv any closer to NATO membership. Ukrainian leaders are still pushing for an invitation to join the alliance despite fierce opposition from Russia — and hesitance among key alliance members. Allies have repeatedly said that “Ukraine’s future is in NATO,” but even top officials in Kyiv acknowledge this cannot happen amid war with Moscow.
The outgoing president may at least be able to ring fence much-needed funding for Kyiv.
Matthew Savill of the Royal United Services Institute think tank in the U.K., said Biden “might choose in his last months in office to use the remainder of the funding available for support to Ukraine under Presidential Drawdown Authority, amounting to over $5 billion.”
The Pentagon has already committed to rolling out new funding packages between now and January totaling some $9 billion. “That is consistent with how we’ve been doing this in the past,” Pentagon spokesperson Sabrina Singh told journalists last week. “It’s something that we’ve done on a pretty regular, almost weekly, basis.”
Biden has also reportedly already decided to allow non-combat American defense contractors to work in Ukraine to maintain and repair U.S.-provided weaponry.
Yehor Cherniev — a member of the Ukrainian parliament and the chairman of his country’s delegation to the NATO Parliamentary Assembly — told ABC News that deeper sanctions on “Putin’s inner circle” are on Kyiv’s wish list, along with the delivery of all previously allocated aid, commitments for more, plus the end to restrictions on Western weapon use inside Russia.
Trump has suggested he would quickly end Russia’s invasion by threatening to cut off military aid to Kyiv unless it agrees to hand Moscow direct or indirect control of swaths of occupied territory in the south and east of the country.
As such, his election has raised concerns in Ukraine of an imminent sellout.
Merezhko, though, stressed the unpredictability of the president-elect. “Trump might become even more critical of Russia to show that all suspicions about him are groundless,” he said.
“We know that Trump loves his country and seeks to protect its interests in accordance with his vision,” Cherniev said. “Therefore, we are confident that the U.S. will not leave us alone with Russia, since this is not in the interests of the U.S. and the free world.”
“However, much will depend on Putin’s willingness to make concessions and compromises,” he added. “If the Russian dictator does not show due flexibility, I think Trump will increase his support for Ukraine.”
As to potential tensions between Trump and Biden in the coming months, Merezhko said, “Competition between them will continue.”
“For us, it would be better if they compete amongst themselves on who will do more for Ukraine.”
European nations, meanwhile, will be bracing for Trump while hoping to influence the president-elect’s take on the war.
Vinjamuri, of the Chatham House think tank, said Europeans will also be working closely with the Biden administration “to put in place everything that they can to keep Europe and Ukraine in as good a place as possible before Jan. 20, when Trump comes in and tries to negotiate a peace deal.”
“That means that getting Ukraine in the best position on the ground, because when you start negotiating a peace, a lot of what gets locked in is based on what land people hold,” she said.
The Middle East
The Biden administration’s pre-election Middle East diplomatic push does not appear to have made significant breakthroughs in either Gaza or Lebanon. Fierce ground fighting and devastating Israeli airstrikes continue on both fronts, with the toll of civilian dead and displaced growing ever larger.
The regional war began with Hamas’ Oct. 7, 2023, attack, which killed around 1,200 people in southern Israel and saw around 250 taken back to Gaza as hostages. Israel’s military response in the strip has killed some 43,600 people and injured more than 102,000, according to the Hamas-run Gaza Health Ministry. Israel’s airstrike and ground campaign in Lebanon has killed more than 3,000 since Oct. 8, 2023, Lebanese health officials say.
Israeli Prime Minister Benjamin Netanyahu replaced Defense Minister Yoav Gallant — one of his prime political rivals and an advocate for a cease-fire deal — on the eve of the U.S. election, reinforcing his position and entrenching his government’s commitment to what he has called “total victory.”
Hafed Al-Ghwell, senior fellow and executive director of the North Africa Initiative at the SAIS Foreign Policy Institute, Johns Hopkins University, told ABC News he has little expectation of peace during Biden’s final months. “I don’t think he has any incentive to do anything,” Hafed said.
“In the case of Israel and Palestine, Biden has taken not just a political stand but an ideological one, and there is no sign that he is going to change that,” Hafed added. “He has called himself a Zionist, and he had ample opportunity to stop this war. Even when the United Nations proposed a resolution to end the occupation, he didn’t support it.”
“It would be really controversial for an outgoing president to make any major decisions,” he continued.
Meanwhile, Netanyahu will be confident in the new White House’s backing in his suppression of Palestinian and Lebanese groups, as well as in his wider showdown with Iran.
Netanyahu “probably feels like he has a free run,” Vinjamuri said. “Even if Biden tried to push him, I’m not so sure he would be responsive, because he knows that Trump is now coming into office.”
Hafed suggested Netanyahu’s domestic concerns, too, will be driving his policy in the coming months. “He knows that the minute this war stops, the Israeli public won’t want him around,” he said. “So, he will continue the war in Lebanon and probably threaten Iran, knowing he will have the full support of Trump.”
Burcu Ozcelik at RUSI said the extent of Trump’s influence over Netanyahu tops “a complex list of unknowns.”
“Trump in recent weeks indicated that he was prepared to give Israel freer rein, provided that the war ended by the time he entered office,” he added.
Those living in the region will be left grappling with the fallout, Hafed continued. “For the people of the Middle East, Biden’s legacy is one of a bloodbath,” he said. “The region is bitter and battered.”

(LONDON) — Israeli forces continued their intense operations inside Gaza after Hamas leader and Oct. 7, 2023 attack mastermind Yahya Sinwar was killed in a firefight with Israeli forces.
The development comes as Israel continues intense air and ground campaigns against Hezbollah in Lebanon and against Hamas in the Gaza Strip, and mulls its response to Iran’s latest ballistic missile attack.
‘Beirut in flames’ after night of airstrikes, foreign minister says
“Beirut in flames,” Israeli Foreign Minister Israel Katz wrote on X on Monday following an intense night of airstrikes on the Lebanese capital.
“A wide-scale Israeli attack targeted Hezbollah’s financial infrastructure in Beirut and across Lebanon last night,” Katz said.
“Massive fires were seen above Beirut as over 15 buildings were struck following evacuation warnings to residents,” the foreign minister wrote.
“Hezbollah has paid and will continue to pay a heavy price for its attacks on northern Israel and its rocket fire. We will keep striking the Iranian proxy until it collapses.”

IDF claims ‘dozens’ of strikes on Hezbollah financial targets
Israel Defense Forces warplanes launched “a series of targeted, intelligence-based strikes against dozens of facilities and sites used by the Hezbollah terrorist organization to finance its terrorist activities,” the IDF said in a Monday post to X.
The Sunday night strikes hit targets in Beirut, southern Lebanon and elsewhere “deep within” the country, the IDF added.
The IDF said the targets were linked to the Al-Qard Al-Hassan Association, which Israel has accused of acting as a key financier of Hezbollah activities.

US investigating intelligence leak on Israel’s alleged plan to attack Iran
Documents purporting to show classified U.S. intelligence-gathering on Israel’s preparations for a possible retaliatory strike against Iran appeared on social media platforms late last week.
The impact of the circulation of these documents on current and future planning by the Israeli military is unclear at this time.
U.S. officials declined to comment on the situation when reached by ABC News. However, a law enforcement source on Sunday confirmed with ABC News that there is an investigation underway.
Markings on the documents indicate that they would have originated from the National Geospatial-Intelligence Agency, which collects, analyzes and distributes intelligence gleaned from satellite and aerial imagery.
If the documents are authentic, it would indicate a major intelligence breach.
According to Mick Mulroy, an ABC News national security and defense contributor, who served as the deputy assistant secretary of defense for the Middle East: “The future coordination between the U.S. and Israel could be challenged, as well.”
The Department of Defense, Federal Bureau of Investigation and a spokesperson for the Office of the Director of National Intelligence all declined to comment when contacted by ABC News.
House Speaker Mike Johnson appeared on CNN Sunday and acknowledged that there is an investigation underway into the possible intelligence leak, adding, “We’re following it closely.”

IDF says it’s targeting infrastructure in Lebanon of group allegedly financing Hezbollah
The Israel Defense Forces announced it was targeting infrastructure Sunday night in Lebanon that has been linked to the Al-Qard Al-Hassan Association, an organization it alleges is involved in financing Hezbollah.
The United States placed sanctions on the Al-Qard Al-Hassan Association in May 2021 related to financing Hezbollah activities.
The Al-Qard Al-Hassan group has 31 branches in Lebanon — including in Beirut and Bekaa, officials said. At least one strike was reported Sunday evening in the Chyah neighborhood of Beirut.
“The ‘Al-Qard Al-Hassan Association’ is involved in financing the terrorist activities of the Hezbollah organization against Israel, and therefore the IDF has decided to attack this terrorist infrastructure,” the IDF said in a statement Sunday. “The IDF continues to work forcefully to destroy Hezbollah’s terrorist infrastructure. Therefore, we call on people inside buildings used by Hezbollah to stay at least 500 meters away from them for the next few hours.”
