The five most shocking discoveries on Mars
October 15 |
On July 31, 2008, the National Aeronautics and Space Administration (NASA) of the United States (U.S.) announced that laboratory tests carried out by the Phoenix mission on Mars proved the existence of water on the so-called red planet.
The U.S. agency dedicated to explore space reported that the robotic arm of the Phoenix deposited a sample taken in an instrument in which water vapors are identified.
“We have water” on Mars, said William Boynton, scientist of the thermal analyzer of the University of Arizona, on that memorable date.
We invite you to know in this article which have been the most shocking discoveries made on Mars.
Lake of liquid water
In 2018 the Marsis radar, installed aboard the Mars Express Orbiter exploration mission coordinated by the European Space Agency (ESA), discovered a lake of liquid salt water which is presumed to be at least one meter deep, reported then the group of Italian scientists who were at the forefront of the discovery.
This important finding is the first sign of liquid water on the fourth planet of the solar system. In the past, Mars had water, however, the cooling of the planet and its weak atmosphere caused it to disappear or turn into ice.
The spiders of Mars
The automatic interplanetary multi-platform station Mars Reconnaissance Orbiter discovered last May 13, 2018 some “giant spiders” on the surface of the red planet.
The “arachnids” correspond to a carbon dioxide ice cap which, once the sunlight hits it, reproduces the false image of the aforementioned animal.
The blue sunsets of the red planet
NASA’s robot explorer Curiosity photographed for the first time the blue sunsets of the red planet. The left camera of the mechanic sent from Earth actually recorded a video of which we know its most beautiful frames.
The image, more than for its beauty, was used by scientists to study the composition and fall of the night dust on Mars, something fundamental to understand the origin of the planet.
Not only sunsets, also blue dunes
The Mars Reconnaissance Orbiter (MRO) discovered large blue dunes with green hues on January 24, 2018.
The coloration is due to methane gas accumulations along with organic molecules in rocks more than 3 billion years old. Most strikingly, the latter could suggest the presence of ancient life forms.
Life on Mars?
The long-awaited life on Mars, whether it is extinct or actually exists, has not been fully proven. So those who want to dream of a destroyed civilization that migrated to Earth must wait a little longer.
However, the Viking probes sent by NASA more than 40 years ago, especially the robotic Labeled Release, or LR, team, provided evidence that could hint at the possibility of ancient life forms, something that is still being investigated by scientists.
So why is Mars red?
Although the fourth planet in the solar system has blue sunsets and blue dunes, from Earth we observe it as red because of the high concentrations of iron oxide on its surface.
So, every time we have the possibility to see the fourth planet of the solar system from our homes, we will still see it red, and we will never be able to enjoy the blue sunsets and dunes. Unless we are ever able to visit Mars.

Mexico and Guatemala launch joint security operation after Agua Zarca border attack
The Government of Mexico announced on Tuesday that it has strengthened coordination with Guatemala following an armed confrontation in the community of Agua Zarca, in Guatemala’s Huehuetenango department, where a soldier was wounded in an attack attributed to organized-crime groups operating on both sides of the border.
The Secretary of Security and Citizen Protection, Omar García Harfuch, confirmed that Mexico is exchanging information with Guatemalan authorities and that Mexican Army units have been deployed along the border to reinforce surveillance and assist in reconnaissance operations.
The attack, Guatemala’s Defense Ministry stated, reflects the “criminal dynamics” dominating that border region, where different groups compete for drug and arms trafficking routes.
According to Guatemala’s Defense Ministry, the clash left a soldier wounded in the leg after suspected criminals crossed from Mexico and opened fire. The wounded soldier is reportedly in stable condition. Authorities also seized high-caliber weapons, explosives, tactical gear and drones, which were handed over for forensic analysis.
Mexican Defense Secretary General Ricardo Trevilla Trejo announced that a coordinated plan of operations will be launched involving both Mexican and Guatemalan forces along the border to counter these criminal networks.
Harfuch emphasized that the violence is not isolated but symptomatic of the ongoing struggle between criminal organizations for territorial control, and reiterated Mexico’s commitment to bilateral security cooperation and its intention to strengthen institutional presence in vulnerable border zones.

Zelensky meets Pope Leo XIV as review of U.S. peace plan continues
Ukrainian President Volodymyr Zelensky met on Tuesday with Pope Leo XIV in Italy, after pledging to deliver a response to the United States regarding the proposed peace plan aimed at ending the war with Russia.
The meeting with the pontiff took place at the papal residence in Castel Gandolfo, near Rome, where Leo XIV “reiterated the need to continue dialogue and renewed his urgent hope that the ongoing diplomatic initiatives may lead to a just and lasting peace,” the Vatican said in a statement.
His visit to Italy follows Monday’s meetings with European leaders in London and Brussels, amid pressure from U.S. President Donald Trump to agree to a peace plan that Zelensky said he is still reviewing.
According to Zelensky, the plan presented by Washington—originally consisting of 28 points—was reduced to 20 after discussions between Ukrainian and U.S. representatives over the weekend. “We are going to work on those 20 points. We are not completely satisfied with the proposals from our partners,” Zelensky said during an online press conference on Monday.

Japan lifts tsunami alert after strong 7.6-magnitude earthquake hits northern coast
A powerful 7.6-magnitude earthquake struck Japan’s northern coast on Monday, triggering several tsunami waves of up to 70 centimeters, authorities said. The tsunami alert was lifted in the early hours of Tuesday.
According to the U.S. Geological Survey (USGS), the quake occurred at 11:15 p.m. local time (14:15 GMT) off the coast of Misawa, at a depth of 53 kilometers. Japan’s Meteorological Agency (JMA) immediately issued a tsunami warning. The first wave reached a port in Aomori Prefecture at 11:43 p.m. (14:43 GMT), followed by others measuring up to 70 centimeters.
Public broadcaster NHK reported that an employee at a hotel in the city of Hachinohe confirmed that several people were injured. Live footage showed shattered glass scattered across roads, while many residents evacuated to the city hall seeking shelter.
The strong tremor was also felt in Sapporo, where emergency alerts were sent to residents’ mobile phones. A reporter in Hokkaido described a horizontal shaking that lasted around 30 seconds, making it difficult to stay standing.
Before the alert was lifted, the JMA had warned of the possibility of tsunami waves up to three meters high along Japan’s Pacific coast. Government spokesperson Minoru Kihara urged residents to remain in safe areas until the warning was officially lifted.
