☆ NASA's James Webb telescope spotted a strange 13 billion-year-old galaxy that shouldn't exist

NASA's new space telescope spotted a 13 billion-year-old galaxy that is much too complex to exist that early in the universe. The galaxy, which is bigger than the Milky Way, could upheave what we know about how dark matter shaped the early universe. Light travels at a fixed speed through space, so the image of these early galaxies in the past is only reaching us now. According to current cosmology models, that should not be possible because dark matter is not supposed to have been mature enough at that time. "This dark matter — we don't know what it actually is —started out really smooth, with only the tiniest of ripples.

☆ Digestive enzymes: Experts weigh in on if they work and more

Whether you should take digestive enzyme supplements depends on several factors, experts say. On its own, the body should produce levels of digestive enzymes sufficient for assimilation of nutrients, Goel said. But when it doesn’t, due to deficiencies evidenced by a stool test a doctor performs, prescription digestive enzymes are the primary treatment. Signs of digestive enzyme deficiencies include diarrhea, stomach pain, bloating, inexplicable weight loss and fatty, oily poop that floats, experts said. Consequently, the only options are to take prescription digestive enzymes or avoid the foods you can’t digest because of your deficiencies.

☆ ‘Tasmanian devil’ is a stellar corpse showing energetic signs of life

CNN —Space is full of extreme phenomena, but the “Tasmanian devil” may be one of the weirdest and rarest cosmic events ever observed. Astronomers dubbed the celestial object the “Tasmanian devil,” and they observed it exploding repeatedly following its initial detection in September 2022. But the Tasmanian devil is revealing more questions than answers with its unexpected behavior. While LFBOTs are unusual events, the Tasmanian devil is even stranger, causing astronomers to question the processes behind the repetitive explosions. We’d never seen that, period, in astronomy.”To better understand the quick luminosity changes occurring in the Tasmanian devil, Ho and her colleagues reached out to other researchers to compare observations from multiple telescopes.

☆ Astronomers detect mysterious 8 billion-year-old energetic burst

A fast radio burst, or FRB, is a pulse of radio-frequency electromagnetic radiation. It lasts a small fraction of a second but outshines most other sources of radio waves in the universe. Radio waves have the longest wavelengths in the electromagnetic spectrum. "The radio waves in FRBs are similar to those used in microwave ovens. Fast radio bursts were discovered in 2007.

☆ Mysterious fast radio burst traveled 8 billion years to reach Earth

The fast radio burst is one of the most distant and energetic ever observed. Fast radio bursts, or FRBs, are intense, millisecond-long bursts of radio waves with unknown origins. Many FRBs release super bright radio waves lasting only a few milliseconds at most before disappearing, which makes fast radio bursts difficult to observe. “J-P showed that the (farther) away a fast radio burst is, the more diffuse gas it reveals between the galaxies. Astronomers said they hope that future radio telescopes, currently under construction in South Africa and Australia, will enable the detection of thousands more fast radio bursts at greater distances.

☆ Earth's neighboring star Betelgeuse unexpectedly got 50% brighter —part of a weird process that will end in the dying star going supernova
▼ + stars: | 2023-05-26 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +5 min

This dying red giant had only recently mysteriously dimmed its shine after an enormous explosion. It is expected to explode into a supernova visible from Earth, though likely not for thousands of years. The red giant — a star not far from death — is now shining about 50% brighter than it usually would, scientists said. Scientists are keeping a close eye on Betelgeuse, as this red giant is a dying star that is close to turning supernova. Betelgeuse could burst into a supernova visible from Earth — one dayA pre-supernova star, called a Wolf-Rayet star, 15,000 light-years away in the constellation Sagittarius.

☆ Galaxies spotted by Webb telescope rewrite understanding of early universe

These galaxies, one of which appears to have a mass rivaling our Milky Way but 30 times more densely packed, seem to differ in fundamental ways from those populating the universe today. "The leading theory is that an ocean of dark matter filled the early universe after the Big Bang," Labbe said. "This dark matter - we don't know what it is actually is - started out really smooth, with only the tiniest of ripples. These ripples grew over time due to gravity and eventually the dark matter started to collect in concentrated clumps, dragging hydrogen gas along for the ride. "Their explosion set off the chain of events that formed subsequent generations of stars," Labbe said.

☆ AT 2022cmc: Rare cosmic event beamed light at Earth from 8.5 billion light-years away

But the rare cosmic event actually occurred 8.5 billion light years away from Earth, when the universe was just a third of its current age — and it has created more questions than answers. This graphic shows how a tidal disruption event might look in space. Carl Knox/OzGrav/Swinburne University of TechnologyWhen a star is torn apart by a black hole’s gravitational tidal forces, it’s known as a tidal disruption event. Observing more events like this could reveal how black holes launch such powerful jets across space, according to the researchers. “Scientists can use AT 2022cmc as a model for what to look for and find more disruptive events from distant black holes.”

☆ Fact Check-Recommendation for social media ID requirements in Australia is from 2021 and has not been implemented
▼ + stars: | 2021-01-05 | by ( Reuters Fact Check | ) www.reuters.com time to read: +3 min

Australia has not implemented “social credit” to access social media platforms, contrary to claims online. Social media users making this claim misrepresent a broadcast that dates to April 2021 about a proposal made by a parliamentary committee looking to reduce “technology-facilitated abuse”. Reuters found no evidence that the recommendation, which proposed requiring a form of identification in order to open a social media account, has been implemented. The Department for Social Services and the House of Representatives Standing Committee on Social Policy and Legal Affairs did not immediately respond to Reuters’ requests for comment. The circulating news video dates to April 2021 and describes a proposal by a committee of the Australian parliament looking into domestic and sexual abuse to require identification to access social media.
