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.

Trump to build $200M ballroom at the White House by 2028
The U.S. government under President Donald Trump announced on Thursday that it will begin construction in September on a new 8,000-square-meter ballroom at the White House.
The announcement was made by Karoline Leavitt, the administration’s press secretary, during a briefing in which she explained that the expansion responds to the need for a larger venue to host “major events.”
“Other presidents have long wished for a space capable of accommodating large gatherings within the White House complex… President Trump has committed to solving this issue,” Leavitt told reporters.
The project is estimated to cost $200 million, fully funded through donations from Trump himself and other “patriots,” according to a government statement. Construction is scheduled to begin in September and is expected to be completed before Trump’s term ends in 2028.
The Clark Construction Group, a Virginia-based company known for projects such as the Capital One Arena and L’Enfant Plaza in Washington, D.C., has been selected to lead the project.
The new ballroom will be built on the East Wing of the White House, expanding the iconic residence with a space designed for state dinners, official ceremonies, and large-scale events.

Three salvadorans in Florida sentenced in $146 million construction tax fraud scheme
Three Salvadoran residents living in Orlando, Florida, were sentenced for conspiracy to commit tax fraud and wire fraud involving a scheme exceeding $146 million in the construction industry, according to the U.S. Attorney’s Office for the Middle District of Florida. The sentence was handed down by federal judge Timothy J. Corrigan on Tuesday, July 29.
Eduardo Aníbal Escobar (45) was sentenced to 4 years and 9 months in prison, Carlos Alberto Rodríguez (36) to 3 years and 4 months, and Adelmy Tejada (57) to 18 months in prison, followed by 6 months of house arrest. All three pled guilty on April 3, 2025.
In addition to the prison terms, the court ordered restitution payments totaling $36,957,616 to the IRS for unpaid payroll taxes, and $397,895 to two insurers for workers’ compensation claims related to the scheme.
Escobar and Rodríguez are permanent legal residents originally from El Salvador, while Tejada is a naturalized U.S. citizen of Salvadoran origin.

Kremlin hails preparedness after Kamchatka quakes leave no casualties
The Kremlin expressed relief that the earthquakes that struck Russia’s Kamchatka Peninsula today —the first being the strongest since 1952— resulted in no casualties, and emphasized that the region is well prepared to face such natural disasters.
“Thank God, there were no victims,” said Kremlin spokesman Dmitry Peskov during his daily press briefing.
The presidential representative stated that “all alert systems were activated in time, and evacuations were organized for residents in areas requiring it in response to tsunami threats.”
“Overall, the seismic resilience of the buildings proved effective (…) Therefore, we can say that the technological preparedness demonstrated a high level,” Peskov added.
