Astronomers discovered Sun-like star that devoured its own planets

New York, Oct 13: Astronomers have discovered that a Sun-like star lurking around 350 light-years away consumed the rocky equivalent of 15 Earths.

Dubbed Kronos after the child-eating Titan of Greek mythology, the star is the clearest and most dramatic case yet of a Sun-like star consuming its own planets, said Semyeong Oh, astrophysicist at Princeton University in New Jersey and lead author of the study.


“Even if our Sun ate the entire inner solar system, it wouldn’t come close to the anomaly we see in this star,” study co-author David Hogg from the Flatiron Institute in New York added.

The research did not begin as a hunt for a planet-eater.

Oh was analysing a catalog of new star data collected by the European Space Agency’s Gaia spacecraft for pairs of stars with similar speeds and trajectories.

Such duos are typically twin stars that formed close together from the same ingredients.

The analysis ultimately led to the identification of Kronos and its lesser known brother Krios.

Their official designations are HD 240430 and HD 240429, and they are both about 350 light years from Earth.

The keys to the discovery were first confirming that the widely separated pair are in fact a binary pair, and secondly observing Kronos’ strikingly unusual chemical abundance pattern, Oh explained in a statement released by the Princeton University.

Other co-moving star pairs have had different chemistries, Oh explained, but none as dramatic as Kronos and Krios.

Most stars that are as metal-rich as Kronos “have all the other elements enhanced at a similar level,” she said, “whereas Kronos has volatile elements suppressed, which makes it really weird in the general context of stellar abundance patterns.”

In other words, Kronos had an unusually high level of rock-forming minerals, including magnesium, aluminium, silicon, iron, chromium and yttrium, without an equally high level of volatile compounds — those that are most often found in gas form, like oxygen, carbon, nitrogen and potassium, the study said.

Feminism itself is nothing but a simple movement that pursues equal rights for women (including transwomen) and against misogyny both external and internal.

"In India, to be born as a man is a crime, to question a woman is an atrocious crime, and this all because of those women who keep suppressing men in the name of feminism."

Feminism, a worldwide movement that started to establish, define and defend equal rights for women in all sections- economically, politically, and socially. India, being a patriarchal society gives a gender advantage to the men in the society thus, Indian feminists sought to fight against the culture-specific issue for women in India. Feminism itself is nothing but a simple movement that pursues equal rights for women (including transwomen) and against misogyny both external and internal. It states nowhere that women should get more wages than men, that women deserve more respect than men, that's pseudo-feminism.

Yakshi statue by Kanayi Kunjiraman at Malampuzha garden, Kerala

Kerala is a land of many good things. It has an abundance of nature, culture, art, and food. It is also a place of legend and myth, and is known for its popular folklore, the legend of Yakshi. This is not a popular tale outside the state, but it is common knowledge for travellers, especially those who fare through forests at night.

The legend of the yakshi is believed to be India's equivalent of the Romanian Dracula, except of course, the Yakshi is a female. Many Malayalis believe that the Yakshi wears a white saree and had long hair. She has a particular fragrance, which is believed to be the fragrance of the Indian devil-tree flowers. She seduces travellers with her beauty, and kills them brutally.

Ancient India not only made mentions of homosexuality but accepted it as well.


The LGBTQ+ acronym stands for Lesbian, Gay, Bisexual, Transgender, Queer, and others. In India LGBTQ+ community also include a specific social group, part religious cult, and part caste: the Hijras. They are culturally defined either as "neither men nor women" or as men who become women by adopting women's dress and behavior. Section 377 of the India Penal code that criminalized all sexual acts "against the order of nature" i.e. engaging in oral sex or anal sex along with other homosexual activities were against the law, ripping homosexual people off of their basic human rights. Thus, the Indian Supreme Court ruled a portion of Section 377 unconstitutional on 6th September 2018.
