When a star swallows a planet... [Now in space]

What happens when a star swallows a planet?



The James Webb Space Telescope has released the results of observing a star 12,000 light-years away from Earth using its observation equipment. NASA reported the news on the 10th (local time).



In conclusion, the star did not swell enough to swallow the planet as previously hypothesized. Instead, the planet's orbit gradually approached the star and was absorbed by the star. As the

The process of a star swallowing a planet revealed by NASA was that a planet the size of Jupiter first orbited very close to the star, closer than Mercury orbiting the Sun.



Then, the planet's orbit gradually decreased over time. The planet gradually approached the star. As it approached the star, the planet began to brush against the star's atmosphere. As the planet fell into the star's atmosphere, it covered the star's surroundings.



Finally, the planet was completely swallowed by the star, spewing out gas from the outer layer of the star.



NASA explained, "This discovery by the James Webb Space Telescope seems to inevitably revise the existing hypothesis," and "It shows that the star did not swell to surround the planet as previously hypothesized, but that the planet's orbit shrank over time, gradually bringing the planet to the brink of extinction."



Ryan Lau, the lead author of this paper and an astronomer at the National Science Foundation (NSF), explained, "This discovery is a very new phenomenon," and "With the James Webb high-resolution infrared observatory, we have been able to obtain valuable information about the fate of other planetary systems, including our own."



Meanwhile, the star observed this time is about 12,000 light-years away from Earth and its official name is 'ZTF SLRN-2020.'



"As the planet got closer and closer to its star, it started to graze the star's atmosphere," said Morgan McLeod of the Harvard-Smithsonian Center for Astrophysics. "At that point, it started to crash into the star at an even faster rate, and as it crashed, the gas from the planet was scattered around the star."



The researchers plan to follow up with more images using the Vera C. Rubin Observatory and NASA's Nancy Grace Roman Space Telescope.



Their results are published in The Astrophysical Journal .

Livestock Manure Methane Is Soaring, But 'Resource Recovery' Isn't Working [Now is a Climate Crisis]

이미지
It has been pointed out that the methane emissions from the livestock waste treatment process were actually reported to be 2.5 times smaller than the previous calculation standards. It is expected that livestock waste will increase rapidly in the future, but an analysis report has been released that 'biogasification', which turns it into a resource, is only at the 10% level. It is urgent to come up with countermeasures as methane, one of the greenhouse gases, is expected to increase rapidly. According to the analysis of the entire livestock waste treatment process for the first time in Korea, the largest source of methane emissions was pigs (73%), and only 14% of pig waste was used for biogas in the public sector. It has been pointed out that it is urgent to come up with countermeasures as methane from livestock waste is increasing rapidly but 'resource conversion' is insufficient.

The Korean launch vehicle Nuriho will be launched for the fourth time in November. Nuriho plans to build technological sophistication through its sixth launch in the future. [Photo = Korea Aerospace Research Institute] Large and small launch vehicle companies have joined forces to develop future space transportation technology. Perigee Aerospace (Perigee) signed a memorandum of understanding (MOU) with Hanwha Aerospace on the 26th to establish a cooperative system between the two companies for the development of space transportation technology. Through this agreement, the two companies plan to share technological and sales capabilities to strengthen space launch vehicle development capabilities and continue strategic cooperation. The Hanwha Aerospace delegation, which visited the Perigee Rocket Development Complex (RDC) in Okcheon, Chungcheongbuk-do, signed the business agreement and toured the development status of the space launch vehicle 'Blue Whale 1 (BW1)' cu...
