About 30 years ago, mother in the UK asked for her child to be medically examined because his face was quite asymmetrical, genetic analysis failed to detect any paternal DNA in his blood. After some complex genetic analysis doctors came to the rather startling conclusion that he was a parthenogenetic chimaera, about half his cells only contained DNA from his mother. The child died a few years later, but his death wasn't related to his condition.

They concluded it is was most likely an unfertilised ovum divided parthenogenically (without fertilisation), it almost formed a teratoma (ovarian teratomas form partenogenetically) but one half was fertilized by a sperm. The result merged to form a viable foetus.

The nearest recognised example of a human virgin birth.

Here is the article.

Meteorites entering the atmosphere don't burn, it's an entirely different and quite complex process.

The high energies and temperatures involved creates dense a plasma surrounding the meteorite composed of excited (electrically charged) molecules, ionised air plasma and ionized meteorite plasma, with temperatures between 2,700 - 50,000 kelvin (some sources say up to 100,000 kelvin).

Magnesium plasma (singly ionized magnesium) in particular is responsible for the green color of some meteors, ionized magnesium (Mg I) emits green light between 517-518 nm.

The Peekskill meteorite created a noticebly green fireball, it was a H6 stony iron condrite (containing orthopyroxene with 17% magnesium).

Other emission lines include ionised iron (blue emission lines) and sodium (yellow-orange emission line), as well as innumerable emission lines from aluminum, calcium, chromium, hydrogen, nickel, silicon, and manganese. These many emission lines merge to form a continuous spectrum (white meteors).

The relative contribution of the main emission lines of iron, magnesium and sodium control the color of meteors, which emission (colour) predominates is related to the meteor's composition and velocity; fast meteors (>30 km per second) ionize magnesium and are green, moderate velocity meteors (30-15km per second) ionize iron and are blue, and slow moving meteors (<15km per second) ionize sodium and are yellow-orange.

Atmospheric air is also ionized at the very high high temperatures involved. Emissions lines from nitrogen, oxygen, and nitrogen oxides are also detected. These are responsible for Persistent Trains, a long lasting dim afterglow of a fireball that can last a few seconds to minutes.

>Subsequent air collisions are predominantly with the vapor cloud (Padevet, 1977), causing atomization and ionization of meteoric vapor and air molecules. In this process, impact excitation, leads to much of the observed optical emission of meteors (Öpik, 1955, 1958).

There's also black body emission from cooling meteoric dust.

Physics of meteor flight in the atmosphere by Ernst Julius Opik

The energy carried by a single photon of 500 nm light is 4.0 × 10^−19 J.

The approximate conversion is 1 Lux = 0.0079 W/m^2 for sunlight that has a peak at 500 nm.

3.16 × 10^21 lux.

The brightness at noon at the equator is 111,000 lux, of which (albedo) for bright sand is 0.4. So sand in desert at the equator at noon, will be around 44,000 lux.

Which is a dynamic range of approximately 1.4 × 10^25 .

Researchers a few years ago discovered that humans can see single photons.

>Here we report that humans can detect a single-photon incident on the cornea with a probability significantly above chance. This was achieved by implementing a combination of a psychophysics procedure with a quantum light source that can generate single-photon states of light. We further discover that the probability of reporting a single photon is modulated by the presence of an earlier photon, suggesting a priming process that temporarily enhances the effective gain of the visual system on the timescale of seconds.

Here in Ireland a radioactive bog was discovered in County Carlow in the 1970s, that left behind yellow uranium rich ash when its turf was burnt. The bog contained between 30-40 tonnes of uranium.
