The US Air Force failed to report a major meteor explosion near a military base in Greenland earlier this summer, leading to concern and confusion.

The explosion contained 2.1 kilotons of force and occurred just above an early-warning radar at the Thule Air Force base in June, according to Hans Kristensen, the director of the Nuclear Information Project for the Federation of American Scientists. Mr Kristensen confirmed the explosion in a tweet on Wednesday, suggesting the meteor could have been mistaken by some as a “Russian first strike”.

However, the US Air Force did not release a statement regarding the meteor, or even tweet about the phenomena.

When contacted for comment, a representative for the secretary of the Air Force public affairs told The Independent: "We’re not providing any comment on that, except that it didn’t impact operations at Thule."

Reporting meteor explosions is not typically a job of the Air Force, though it would be considered commonplace for any military branch to at least acknowledge an incident of this magnitude near one of its bases.

The Thule Air Base public news site includes no information surrounding the meteor whatsoever, along with all other web domains associated with the base.

Still, the incident was confirmed in part by data published by NASA’s Jet Propulsion Laboratory, which showed an object travelling nearly 24.4 kilometres per second over Thule on 25 July around midnight.

Had the space rock broken through the Earth’s atmosphere at a slightly different angle, there could have been potentially fatal consequences.

For example, a large meteor struck Chelyabinsk, Russia in 2013, causing damage to nearly 7,000 buildings and injuring 1,500 people.

Until now, astronomers believed there were just two in the last 220 years. But the discovery of this painting by Frederic Church, and its link to Walt Whitman's Year of Meteors poem, has led to the re-discovery of another example of the event, witnessed by both men in 1860 JUDITH FILENBAUM HERNSTADT Written in the skies: The truth behind 'Year of Meteors' Van Gogh in Provence Art historians once believed that the canvas below depicted a setting sun in Saint- Remy-de-Provence, painted by Vincent Van Gogh in 1889. But astronomers led by Professor Olson travelled to the French town and pinpointed the exact location of the painting. Using maps and records, they calculated it actually showed the moon rising at 9.08pm on 13 July 1889 AP Written in the skies: The truth behind 'Year of Meteors' The Canterbury Tales When a colleague of Professor Olson complained of being unable to decipher a passage in Chaucer's Canterbury Tales referring to a strange high tide, he decided to run a computer simulation recreating medieval tidal positions. He found that there had indeed been extremely high tides in 1340. Professor Olson said: 'Most people see liberal arts on one side and sciences on the other, but I get to break those barriers down' AP Written in the skies: The truth behind 'Year of Meteors' The Scream With its dramatic red sky, Edvard Munch's The Scream is renowned as a depiction of despair. Less well known is the fact that the Norwegian artist was merely recreating what he saw in Oslo in 1883. Professor Olson's team found that the eruption of Mount Krakatoa in Indonesia led to a series of sunsets in Norway which made the sky seem ablaze AP Written in the skies: The truth behind 'Year of Meteors' Caesar invades Britain, 55BC Historians have long argued over the date of Julius Caesar's invasion of Britain in 55BC, finally settling on 26-27 August. But in 2007 the American researchers visited the English Channel and, after recreating the precise tidal conditions, announced that the invasion of 100 Roman warships must have taken place on 22-23 August Alamy

It remains unclear why the Air Force did not release a statement regarding the meteor last month. The military branch contacted its “space command” during the incident, the Military Times reported in a piece debunking claims about the explosion.
