Geminids meteor shower began life in a ‘violent catastrophe’, scientists say
Geminids meteor shower began life in a ‘violent catastrophe’, scientists say
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.

Khloe Kardashian defended after trolls 'body shaming' new bikini pics
Fans of Khloe Kardashian have defended the reality star against trolls “body shaming” her over a new bikini pic. Kardashian shared an image with her 309 million Instagram followers. It showed her in a gold bikini with the image taken from her behind her, revealing her bottom. She was captured on a beach with the waves and blue sky ahead of her. The picture was taken as part of an advertising campaign for her own Good American apparel brand which recently partnered with the brand Body Glove on a new swimwear range. In another picture, the reality star posed laying on top of a surfboard and in a clip, she emerged from a swimming pool wearing the same gold bikini. But, it was the image baring her bottom that caught the eye as some Instagram users launched nasty comments at the star. Sign up to our free Indy100 weekly newsletter One Instagram user asked, “What’s with the weird vein on your tush?!” leading to a whole host of others making unsolicited comments about Kardashian’s appearance. Another fan hit back: “What vein? Even if there was a vein, which there isn’t. What’s wrong with a vein? Since when do we control or tell veins in our body where to go and not to go?” Others also came to the defence of the star, with someone asking “What’s with the body shaming?” Kardashian has been known to hit back at trolls who have commented on her social media posts, previously giving the best one-world response to someone who asked, “Do you miss your old face?”.
