The Geminids meteor shower began in a “violent catastrophe”, scientists have found. Every winter, the world is delighted by the meteor shower, which brings some of the most intense display of ‘shooting stars’. But that spectacle has been rivalled by its mystery. The Geminids are unusual in that most meteor showers are created when a comet leaves behind a tail of ice and dust – but the Geminids come from an asteroid, which do not usually leave behind a tail. Asteroids are chunks of rock and metal flying around in space. The Geminids appear to originate with one called 3200 Phaethon, which for an unexplained reason is affected by the Sun and leaves behind a stream across the night sky. “What’s really weird is that we know that 3200 Phaethon is an asteroid, but as it flies by the Sun, it seems to have some kind of temperature-driven activity,” said Jamey Szalay, research scholar at the Princeton University space physics laboratory and co-author on the paper. “Most asteroids don’t do that.” Attempts to solve that mystery have struggled in part because the meteor shower has only been observed from Earth. Now, however, researchers using Nasa’s Parker Solar Probe have been better able to examine the the Geminids. They suggest that a violent, catastrophic event gave rise to the meteor shower. That could have been a high-speed collision with another object in space, for instance, or a gaseous explosion. Some researchers have previously suggested that 3200 Phaethon might really be a comet, and that it lost its snow to leave behind just a rocky core that looks like an asteroid. But the new study makes clear that the origins of the meteor shower are much more dramatic than that. In an attempt to understand the meteor shower, researchers simulated three possible formation scenarios and then compared them with models based on observations from the Parker Solar Probe. That included a less violent scenario, a more violent one, and another that was in line with a comet. When they compared those scenarios with the actual observations, they found that the violent one was the most similar. That suggests that it was the result a collision or similar dramatic event. Researchers still do not know for sure what happened. But the new study helps narrow down the possibilities – as well as shedding more light on such events in space. The findings are published in a new article, ‘Formation, Structure, and Detectability of the Geminids Meteoroid Stream’, published in Planetary Science.

Could we have aliens to thank for preventing a nuclear war on Earth? That’s what one former Nasa astronaut has claimed. Edgar Mitchell, who was involved in the Apollo 14 mission, gained a reputation for sharing conspiracy theories when he arrived back from the moon in 1971. Mitchell was the sixth man on the moon and was the Lunar Module Pilot on Apollo 14. Before his death in 2016, Mitchell spoke at length claiming that aliens visited Earth. Speaking to the Mirror, he alleged that aliens were responsible for preventing nuclear war between the US and the Soviets at the height of Cold War tensions. Sign up to our free Indy100 weekly newsletter At the time, Mitchell focused on the White Sands Missile Range facility in New Mexico. “White Sands was a testing ground for atomic weapons – and that's what the extraterrestrials were interested in,” he said. "They wanted to know about our military capabilities. My own experience talking to people has made it clear the ETs had been attempting to keep us from going to war and help create peace on Earth." White Sands Missile Range is where the first atomic bomb was tested in 1945, and Mitchell claimed that officers there had told him aliens had shot down missiles flying over the site. The claims were, as you’d expect, disputed. UFO expert Nigel Watson told IFL Science at the time: "To me, this is just another case of UFO fantasy and speculation. When you try getting to the facts it is like trying to herd cats." Meanwhile, a UFO conspiracy theorist recently described the south pole as an “air traffic control” hub for aliens. A recent discussion centred on the Amundsen–Scott South Pole, which Eric Hecker claimed communicated with “exotic” crafts by sending neutrino rays up into space. Hecker went further by talking about “digital optical modules” buried a mile beneath the surface under the ice. He claims they were buried in order to detect neutrino interactions while being deep enough not to interfere with radiation readings. Have your say in our news democracy.
