Learn about seven important NASA discoveries
October 15 |
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.

FBI Says It Disrupted Alleged Plot Targeting White House During UFC Event
The Federal Bureau of Investigation (FBI) announced Tuesday that it had disrupted an alleged plot to attack the White House during a major Ultimate Fighting Championship (UFC) event held in Washington over the weekend.
FBI Director Kash Patel said the threat was identified on June 10 through a joint investigation involving multiple law enforcement agencies. According to Patel, swift action by authorities led to the arrest of several suspects before the alleged plan could be carried out.
“On June 10, the FBI and our law enforcement partners became aware of a potential threat targeting UFC America 250 in Washington. Thanks to the rapid response of the FBI and our partners, multiple individuals are now in custody, and the alleged attack plans were stopped before they could be executed,” Patel said.
He emphasized that the operation demonstrated the ability of security agencies to detect and prevent potential threats at large public gatherings. Patel added that the investigation remains ongoing and that additional details will be released as court proceedings move forward.
According to reports from U.S. media outlets, five individuals have been arrested so far. The suspects were identified as Tycen Proper of Ohio, Daniel Eskridge of Missouri, Abraham Hermosillo Álvarez of Nebraska, and Bryan Omar Roa and Michael Alan Thomas, both from California. Authorities are also investigating the possible involvement of 18 additional individuals.
Investigators allege that the plot involved the use of drones equipped with explosives to target buildings near the sporting event. The plan reportedly sought to trigger a mass evacuation and direct attendees toward areas where snipers were allegedly positioned. Authorities further claim that a second phase of the operation included an attempted assault on the White House.
The U.S. Secret Service confirmed that it worked closely with the FBI throughout the operation. Secret Service Director Sean Curran stated that security teams conducted extensive efforts to identify those involved and eliminate any threat to attendees and protected facilities.
The investigation reportedly uncovered communications conducted through the messaging application Signal, where several suspects allegedly discussed details related to the planned attack. A forensic analysis of one of the seized mobile phones revealed at least 23 users participating in conversations connected to the alleged planning activities.
Court documents also indicate that some of the suspects allegedly intended to target U.S. political figures. Among the reported targets were members of Congress who had received contributions from the American Israel Public Affairs Committee (AIPAC). Investigators further stated that one of the primary suspects had posted antisemitic messages and expressions of support for Adolf Hitler on social media, evidence that is now part of the ongoing judicial investigation.

Brazil helicopter crash in Rio de Janeiro kills six, including pilots and international figures
The Rio de Janeiro Civil Police confirmed on Monday the identities of three of the six victims killed in a helicopter collision that occurred the previous morning in the Recreio dos Bandeirantes neighborhood.
All three identified victims are Brazilian nationals: the pilots of the aircraft, Charles Marsillac and Alexandre Souza, and music producer Lucas Brito.
The identities of the three foreign victims have not yet been officially confirmed. They include U.S. singer Oliver Tree, Argentine YouTuber Gaspar Prim—known online as “Gaspi”—and Argentine producer Lucas Vignale, all of whom were listed on the flight manifest.
According to police, forensic experts from the Legal Medical Institute have already collected DNA samples in order to identify the foreign victims, whose bodies were severely burned.
One of the helicopters crashed into a private parking lot, triggering a fire that destroyed around twenty electric vehicles. That aircraft was carrying the pilot and four passengers, including the three foreign nationals.
The second helicopter, which had only the pilot on board, crashed approximately 100 meters away from the first impact site.
Rio de Janeiro’s deputy mayor, Eduardo Cavaliere, stated that both helicopters were operating transport flights toward Angra dos Reis on the Rio coastline and toward the mountainous region of the state.
Oliver Tree, 32, was in Brazil as part of an international tour. The artist, known for songs such as “Life Goes On” and “Miss You,” had performed to a large audience in São Paulo a week earlier and was scheduled to continue his tour in Europe.
Argentine content creator Gaspar Prim, 23, had built a following of more than two million on social media platforms, gaining popularity for humorous and often controversial video productions that had occasionally been removed by hosting platforms.

Mexico and U.S. Launch New Bilateral Security Group to Combat Fentanyl and Organized Crime
The governments of Mexico and the United States officially launched the Bilateral Implementation Group (BIG) on Friday, a new initiative aimed at strengthening cooperation on security issues and enhancing joint efforts against transnational crime.
In a statement, U.S. Ambassador to Mexico Ronald Johnson announced that he and Deputy Foreign Minister Roberto Velasco addressed officials from both countries who will lead what he described as a “new phase of bilateral cooperation.” The initiative seeks to curb the flow of fentanyl and other illicit drugs, illegal firearms, and human trafficking across the shared border.
Earlier this week, Mexico’s Ministry of Foreign Affairs had confirmed that senior security officials from both nations would meet in Mexico City on June 12 to review and advance existing cooperation agreements.
Through social media, Ambassador Johnson explained that the new bilateral group is designed to improve coordination between the two governments by placing greater emphasis on implementation, accountability, and measurable results. The effort will also focus on combating transnational criminal organizations operating across North America.
“The participation of 15 U.S. government agencies, working alongside their Mexican counterparts, reflects the seriousness of this effort and our shared commitment to delivering measurable results,” Johnson said.
The ambassador also highlighted several achievements that he attributed to ongoing bilateral cooperation. According to Johnson, maritime drug trafficking into the United States has declined by more than 95 percent, while overdose deaths have fallen by 35 percent.
He further noted that Mexican authorities have seized more than 400 metric tons of illegal drugs and dismantled over 2,300 clandestine laboratories as part of their efforts to combat organized crime and narcotics production.
The launch of the Bilateral Implementation Group marks the latest step in the security partnership between Mexico and the United States, as both countries seek to address shared challenges related to drug trafficking, arms smuggling, human trafficking, and the activities of criminal networks operating across the region.
