NASA is studying the emissions of plants from space.
First-of-its-Kind Fluorescence Map Offers a New View of the World's Land PlantsScientists from NASA's Goddard Space Flight Center in Greenbelt, Md., have produced groundbreaking global maps of land plant fluorescence, a difficult-to-detect reddish glow that leaves emit as a byproduct of photosynthesis. While researchers have previously mapped how ocean-dwelling phytoplankton fluoresce, the new maps are the first to focus on land vegetation and to cover the entire globe... Chlorophyll fluorescence offers a more direct window into the inner workings of the photosynthetic machinery of plants from space.
Emissions studied by NASA are namely "Chlorophyll fluorescence".
For NASA Chlorophyll fluorescence is the name of the game.
This was known recently, however it was portrayed in the Quran 1400 years before it was discovered. In chapter "The Light" olive oil emits light without fire.
٣٥ اللَّهُ نُورُ السَّمَاوَاتِ وَالْأَرْضِ ۚ مَثَلُ نُورِهِ كَمِشْكَاةٍ فِيهَا مِصْبَاحٌ ۖ الْمِصْبَاحُ فِي زُجَاجَةٍ ۖ الزُّجَاجَةُ كَأَنَّهَا كَوْكَبٌ دُرِّيٌّ يُوقَدُ مِنْ شَجَرَةٍ مُبَارَكَةٍ زَيْتُونَةٍ لَا شَرْقِيَّةٍ وَلَا غَرْبِيَّةٍ يَكَادُ زَيْتُهَا يُضِيءُ وَلَوْ لَمْ تَمْسَسْهُ نَارٌ ۚ نُورٌ عَلَىٰ نُورٍ ۗ يَهْدِي اللَّهُ لِنُورِهِ مَنْ يَشَاءُ ۚ وَيَضْرِبُ اللَّهُ الْأَمْثَالَ لِلنَّاسِ ۗ وَاللَّهُ بِكُلِّ شَيْءٍ عَلِيمٌ
"Its oil would almost illuminate, even if no fire has touched it" this is light without fire. Today we know what it is, Chlorophyll fluorescence.
"Light upon light" today we know that we can only see a small part of the spectrum. The rest of the spectrum we cannot see but it is all light.
How could an illiterate man who lived 1400 years ago have known about Chlorophyll fluorescence?
The Quran (Koran, the book of Islam) contains scientific knowledge that could not have been known 1400 years ago. It ranges from basic arithmetics to the most advanced topics in astrophysics. You are invited to go through those miracles and judge for yourself.
