A ‘monster’ star 2 million times brighter than the sun disappears without a trace<\/a><\/h4>\n

<\/p>\n

In 2019, scientists witnessed a massive star 2.5 million times brighter than the sun disappear without a trace.\u00a0Now, in a new paper published today (June 30) in the journal\u00a0Monthly Notices of the Royal Astronomical Society<\/u><\/a>, a team of space detectives (see: astrophysicists) attempt to solve the case of the disappearing star by providing several possible explanations. Of these, one twist ending stands out: Perhaps, the researchers wrote, the massive star died and collapsed into a black hole without undergoing a supernova explosion first \u2014 a truly “unprecedented” act of stellar suicide.<\/p>\n

Long-term exercise impacts genes involved in metabolic health<\/a><\/span><\/h2>\n

This suggests that even short training programs of 6\u201312 months are enough to positively influence the health of people suffering from metabolic disorders,” says last author Carl Johan Sundberg, professor at the Department of Physiology and Pharmacology, Karolinska Institutet. “The study identifies important ‘exercise-responsive’ genes that may play a role in metabolic diseases.<\/p>\n

Flat spots on Saturn\u2019s moon Titan may be the floors of ancient lake beds<\/a><\/span><\/h2>\n

<\/p>\n

Peculiar flat regions on Saturn\u2019s moon Titan could be the dry floors of ancient lakes and seas. The suggestion, published June 16 in\u00a0Nature Communications<\/em>, may\u00a0solve a 20-year-old mystery<\/a>. The researchers considered whether rainfall, dunes or dry lake beds could be responsible for the reflections, and found that only lake beds explain the timing and locations of the signals. It does rain on Titan, but not frequently enough to explain the reflections, and Titan\u2019s dune fields are in the wrong spots. And the specular reflections come from two specific regions that look like other\u00a0empty lake basins near Titan\u2019s poles<\/a>\u00a0(SN: 4\/15\/19<\/em>).<\/p>\n","protected":false},"excerpt":{"rendered":"
