NASA confirms Earth now has two moons until 2083

Publisher’s rating: Misleading

The review says NASA did not announce that Earth has two moons; it explains that asteroid 2025 PN7 follows a path similar to Earth’s until around 2083. The asteroid orbits the Sun rather than Earth, so the review says it is a quasi-moon, not a true natural satellite.

NASA confirms a giant dam shifted Earth’s axis and made days shorter.

Publisher’s rating: Misleading

NASA’s calculation was a theoretical model, not confirmation that the dam had measurably changed Earth’s rotation. The model estimated that filling the reservoir would make days slightly longer by about 0.06 microseconds and shift the rotational pole by roughly 2 centimeters—the opposite of the claim that days became shorter.

“சூரியனிலிருந்து வரும் புற ஊதாக் கதிர்கள் பூமியிலுள்ள வளி மண்டலத்தில் பட்டு சிதறுவதால் தான் வானமும் கடலும் நீல நிறமாக இருக்கின்றன. மேலும் இந்த ஓசோன் படலம் என்பது பூமியின் காடுகளில் உள்ள மரங்களாலும் மற்றும் கடலில் உள்ள நீலப் பச்சை பாசிகளாலும் தான் உருவாகிறது’ - சீமான்.

The viral video shows real insects in the shape of flowers

Publisher’s rating: FALSE

FACTLY reports that the video’s nine clips were originally shared by the Instagram page oleg.pars, which identifies the visuals as AI creations. It says reverse-image searches and analysis with Hive AI-detection tools supported the conclusion that the clips were generated using AI, not footage of real insects.

Four Nigerian girls invented a generator that produces six hours of electricity using just one litre of urine as fuel.

Publisher’s rating: MISLEADING

FACTLY reports that four Nigerian schoolgirls showcased a urine-powered generator in 2012, but says the evidence does not establish that it could provide six hours of electricity from one litre of urine. The review notes that a documentary showed it powering simple light bulbs or a wall light, while experts raised concerns about its efficiency and practicality.
