As part of the commemoration of the discovery of the exoplanet Kepler 452-b, by the National Aeronautics and Space Administration (NASA) of the United States (U.S.), this Sunday is worth knowing seven important discoveries of this U.S. agency in recent years.

The cosmic body identified by the Kepler telescope, to which it owes its name, was confirmed by NASA on July 23, 2015.

Kepler-452b is an exoplanet, a planet revolving around a star other than the Sun, which in this case is a G2-type yellow dwarf, which is known as Kepler-452.

The agency responsible for the civil space program, as well as for aeronautical and aerospace research, since its foundation in 1958 has developed space exploration and science projects, which have led to relevant discoveries in several aspects.

1) The study of twins
In April 2019 NASA published the controversial results of an investigation known as the Twins Study.

A set of ten teams of researchers from the United States (U.S.) set out to observe the changes that might occur to a human being when exposed to the risk of traveling into space for a year.

The scientists compared a wide range of samples and measurements from identical twin brothers, retired astronauts Scott Kelly and Mark Kelly. Scott was sent into space, while Mark remained on Earth.

One of the results revealed the lengthening of the space-bound twin’s telomeres, special features at the ends of each strand of DNA that generally shorten with age, which demonstrated how a human body can adapt to a variety of changes generated by the environment of outer space flight.

2) Observing the Earth from space
There are a wide variety of scientific studies based on images that NASA crew members take using Crew Earth Observations (CEO).

NASA’s orbiting space station carries its crew and cameras over different points on Earth at different times and the station revisits the sites at varying intervals, allowing images of many areas to be collected at different times of the day and night.

In this way experts discovered that artificial lighting at night affects the behavior of urban wildlife, according to a study of light levels in the city of Chicago that was based on images taken by astronauts from the International Space Station (ISS).

3) A revealing microscope
A miniaturized fluorescence microscope made it possible to observe changes in living cells in microgravity.

This microscope enables real-time analysis of cell behavior during long-duration spaceflight. Its rapid imaging capability allows monitoring of cellular and molecular reactions that can happen more rapidly in altered gravity environments.

The implementation of real-time analysis methods on the station furthers the understanding of how cells in the human body react and adapt to the space environment.

4) The universe in better resolution
NASA’s Neutron Star Interior Composition Explorer (Nicer) facilitates measurements with excellent precision of neutron stars, objects containing ultra-dense matter at the threshold of black hole collapse.

In early 2018 JAXA’s All-Sky X-ray Imaging Monitor (MAXI) captured a new transient X-ray source in the sky designated MAXI J1820 + 070.

Nicer began monitoring the source and discovered that it was a binary black hole system with a mass much larger than that of the Sun. In addition, recorded measurements have revealed how the inner edge of a black hole’s accretion disk (and the corona above it) vary in size and shape as a black hole consumes material from a companion star.

5) Spaceflight decreases crew performance on Earth.
Astronauts’ bodies adapt to microgravity while in space. When crew members return to Earth, they show significant decreases in manual dexterity, multitasking, motion perception, and the ability to operate a vehicle.

NASA researchers confirmed that the post-flight performance decline was related to spaceflight factors and not to other factors such as lack of practice or sleep.

6) Cement in space
Another discovery confirmed by NASA suggests the possibility of building places to live on the Moon or Mars.

It is a research called Microgravity Investigation of Cement Solidification (MICS), which reveals that samples processed in space show considerable changes in the microstructure of cement compared to those processed on Earth, such as increased porosity, or the presence of more open spaces.

Showing that cement can harden in space is of great importance for future lunar constructions.

7) Keep it clean
New materials are needed to slow the growth and spread of bacteria resistant to antibiotics and silver coatings, according to research called Biorisk-KM-Metally, conducted by the Russian space agency (Roscosmos) and confirmed by NASA.

The researchers conducted tests on an antimicrobial coating called AGXX® and compared it with silver and stainless steel coatings. For the study, crew members placed 12 plates on the space station’s toilet door, with one plate coated in each tested material to be collected at six, 12 and 19 months.

In all time lapses, the experts found that the AGXX® coating had significantly fewer bacteria than surfaces coated with silver and stainless steel. These data are useful for the development of ideal technologies to reduce the risk of biological damage to space hardware and equipment.

IEA warns Middle East conflict could spark worst energy crisis in decades

The ongoing conflict in the Middle East could trigger the worst energy crisis in decades, warned Fatih Birol, head of the International Energy Agency (IEA), who described the situation as “very serious.”

Speaking at the National Press Club in Canberra, Birol compared the current scenario to the oil crises of the 1970s, noting that during those events the world lost around five million barrels of oil per day in each crisis.

“Today, we have lost 11 million barrels per day—more than the two major oil shocks combined,” he said.

The Turkish economist referred to the conflict that began on February 28, following attacks by the United States and Israel against Iran, which have significantly disrupted global energy markets and driven oil prices higher.

Birol warned that the global economy is facing a “very, very serious threat” and expressed hope that the crisis will be resolved soon.

“No country will be immune to the effects of this crisis if it continues in this direction. Global efforts are urgently needed,” he emphasized.

Colombian Air Force Hercules plane crashes during takeoff with troops onboard

A Lockheed C-130 Hercules operated by the Colombian Air Force was involved in a “tragic accident” while taking off from Puerto Leguízamo, in the Putumayo department of southern Colombia, as it was transporting troops, Defense Minister Pedro Sánchez reported on Monday.

The minister stated on social media that the exact number of victims and the causes of the crash have not yet been determined. He also extended his condolences to the families affected and urged the public to avoid speculation until official information is confirmed.

“This is a deeply painful event for the country. Our prayers are with the victims and their families,” Sánchez said, adding that emergency protocols have been activated and an investigation is underway.

Meanwhile, President Gustavo Petro expressed hope that there would be no fatalities in what he described as a “horrific accident that should not have happened.”

Petro also highlighted ongoing efforts to modernize the country’s air fleet and reiterated the need to acquire new helicopters and transport aircraft to strengthen military mobility, particularly in remote regions.

Paris prosecutors alert U.S. over alleged deepfake strategy linked to Elon Musk

The Paris Prosecutor’s Office said on Saturday that it had alerted authorities in the United States over suspicions that tech entrepreneur Elon Musk may have encouraged the spread of sexualized deepfake content on the social platform X to artificially boost the company’s valuation.

According to prosecutors, the controversy surrounding explicit AI-generated videos—reportedly linked to Grok, the platform’s artificial intelligence system—may have been deliberately triggered to increase the market value of X and X AI.

The office added that the alleged strategy could be tied to the planned June 2026 public listing of a new entity formed through the merger of SpaceX and X AI.

French authorities said they contacted the U.S. Department of Justice as well as legal representatives at the U.S. Securities and Exchange Commission (SEC) earlier this week to share their concerns.

Responding on X in French to a report about the case, Musk referred to French prosecutors using an offensive term.

When contacted, X’s legal representative in France did not immediately comment.

Grok, the platform’s AI system, has its own account on X, allowing users to interact with it or request content generation. For a period, users were able to tag the bot in posts to generate or edit images, a feature that may have facilitated the spread of such material.
