HOW SATELLITES DETECT LIGHTNING
In 1997, NASA sent a lightning sensor into orbit aboard TRMM to study storms. 29 years later, the mission’s data still helps scientists understand lightning, rainfall and climateNASA's Lightning Imaging Sensor aboard TRMM studied lightning's role in weather. Earlier missions observed lightning from space, revealing ...

In 1964, NASA first tracked a satellite with lasers; the method later helped measure sea-level rise and ice lossIn 1964, NASA researchers made history by tracking a satellite for the first time using a laser beam. Leveraging spare radar components and...
Chinese humanoid robot beats Usain Bolt's 100m record at Beijing gamesA Chinese humanoid robot named Tiangong Ultra ran 100 meters in 9.39 seconds. This impressive speed surpassed Usain Bolt's previous world r...
From Thumba to tomorrow: Indian space programme is preparing for its biggest leap yetIndia's space program began with a small rocket range in 1962. It progressed to launching its first satellite and developing indigenous lau...
In 1850, scientists began recording the temperatures that would reveal Earth's climate trajectory. 172 years later, researchers found 45 years of satellite observations are enough to detect human warming in most regionsScientists developed a new method to identify regional climate change patterns. This approach uses observed temperature records to pinpoint...
At 7, Jammy-born boy entered Guinness records as world’s youngest male webmaster. Now 20, he’s raised $4.3 million to fix a major space communication problemJammu-born Onkar Singh Batra is building a space communication network. His startup Apolink aims to keep satellites connected beyond ground...
In 1985, NASA astronauts built two giant “flyswatters” aboard Space Shuttle Discovery; they used them in an attempt to activate a stranded satelliteIn the remarkable year of 1985, astronauts faced a daunting challenge when they crafted makeshift tools from spare materials aboard their s...
Texas used towering wind turbines as accidental frost fans based on a 2019 NASA observation; the result warmed ground temperatures 4–7°F on winter nightsWind turbines can mix warmer air downward during winter nights. This effect is similar to frost fans used in orchards. Satellite observatio...
Tiangong Ultra, the Chinese humanoid robot that beat Usain Bolt’s 100m record, barely made the human cut in a Half-Marathon last yearTiangong Ultra, a Chinese humanoid robot, achieved an astonishing feat by completing 100 meters in just 9.39 seconds, eclipsing the legenda...
In 1986, Voyager 2 discovered 10 moons around Uranus. 39 years later, Webb found a 29th moon only 10 kilometre wide that the spacecraft had missedIn 1986, Voyager 2 discovered 10 moons around Uranus during its flyby. Thirty-nine years later, James Webb Space Telescope observations ide...
In 2019, fewer than 2,000 active satellites circled Earth as SpaceX began scaling Starlink. Seven years later, 15,711 were orbiting the planet, with Starlink accounting for 65.97% of the working satellitesSince 2019, the number of active satellites around Earth has surged nearly eightfold, with SpaceX's Starlink making up about two-thirds of ...
In the 1960s, 2025 PN7 began travelling in step with Earth. 60 years later, American astronomers discovered it and found older images hiding the asteroid in plain sight2025 PN7 was hiding in plain sight for decades. The tiny asteroid has been traveling around the Sun in step with Earth since roughly the 19...

Why a radio telescope can be built from cardboard and aluminum foil: the metal-lined horn reflects radio waves toward a receiverDedicated hobbyists and curious students are assembling radio telescopes from common household objects. These innovative instruments catch ...
A US satellite detected a mysterious flash in 1979; the CIA said it was probably a nuclear test, but nearly 50 years later, the mystery remains unsolvedA US satellite observed dual flashes in the South Atlantic back in 1979, leading intelligence officials to speculate a nuclear test with no...
In 1859, the Carrington storm caused spectacular auroras and electrical disturbances in telegraph networks as far south as Cuba. 167 years later, a repeat could cripple key infrastructure while leaving some electronic devices surprisingly unaffectedThe Carrington storm of 1859 highlighted our planet's susceptibility to solar flares. If a similar phenomenon occurred today, it could caus...
In 1967, US satellites searching for nuclear tests detected mysterious flashes from space. Decades later, scientists uncovered secrets of gamma-ray bursts, which can release more energy in 10 seconds than Sun will emit over its entire 10-billion-year lifetimeGamma-ray bursts, first detected accidentally in 1967, have long puzzled astronomers. Recent observations of their afterglows are now chall...
