Angel hair, siliceous cotton, or Mary's yarn is a sticky, fibrous substance reported in connection with UFO sightings, or manifestations of the Virgin Mary. It has been described as being like a cobweb or a jelly.

It is named for its similarity to fine hair, and in some cases, the substance has been found to be the web threads of migrating spiders. Reports of angel hair say that it disintegrates or evaporates within a short time of forming.

Sightings

There have been many reports of falls of angel hair around the world. Angel hair was reported at the Miracle at Fatima on 13 September and 13 October 1917.

The most widely reported incidence occurred in Oloron, France in 1952, when "great flakes" were reported as falling from a nearly cloudless sky. On October 27, 1954, Gennaro Lucetti and Pietro Lastrucci reported standing on the balcony of a hotel in St. Mark's Square in Venice and seeing two "shining spindles" flying across the sky leaving a trail of the angel hair.

In New Zealand and Australia, local newspapers have reported many sightings since the 1950s, although many have been identified as spider webs after analysis. An incident was reported in Polonnaruwa, Sri Lanka on October 20, 2014.

Published explanations

Explanations based on known phenomena include:

  • Some types of spiders are known to migrate through the air, sometimes in large numbers, on cobweb gliders.
  • In Évora, Portugal, on November 2, 1959, a substance described as angel hair was collected and analyzed under a microscope by a local school director and later by armed forces technicians and scientists of the University of Lisbon. The scientists concluded that the angel hair was likely produced by a small insect of an unknown species or perhaps some kind of single-celled organism.
  • Atmospheric electricity may cause floating dust particles to become polarized, and attraction between these polarized dust particles may cause them to join together, to form long filaments.
  • On two occasions, samples were sent for testing. On October 13, 1917, a sample found at Cova da Iria was sent to Lisbon and on October 17, 1957, another sample found at Cova da Iria was examined. The analysis found this to be natural, consisting of white flakes. When put under a microscope it was found to be a vegetable product, not animal.

Explanations based on folklore include:

  • During the ascension of the Virgin Mary, her veil was torn and spread throughout the air, leading to the title of Mary's yarn.

Angel grass

"Angel grass" is a related phenomenon. It is when short metallic threads fall from the sky, often forming intertwined loose masses.
