Gecko Capital's Maunakea Emerging Markets Debt Recovery Fund has delivered an impressive 74% return over the past year, and its fund manager is particularly bullish on two South American economies looking ahead. Maunakea's two largest positions are in Venezuela and Argentina, which Durand considers among "the most attractive and compelling" trades he has ever placed. Elections are expected to be held on 28 July which will be a key moment for investments in the country, according to the fund manager. However, the fund manager is optimistic that Argentina will reverse its economic woes. The next trade Durand said he is eyeing Bolivia, once a market darling that has recently experienced significant problems, for opportunities as its bonds start to trade at discounted levels.

Read previewThe supermassive black hole at the heart of our galaxy has a side you've never seen before. A new image reveals powerful magnetic fields swirling around our hometown black hole, which is called Sagittarius A* (pronounced "A-star"). EHT had previously imaged its first black hole, Messier 87, in polarized light as well, though it doesn't look quite as striking:The Messier 87 supermassive black hole imaged in polarized light. EHT CollaborationSince both black holes have similar structures of magnetic fields, despite their immense difference in size, the EHT scientists now suspect that all supermassive black holes might have magnetic structures like this. Bigger black hole breakthroughs may be in storeFurther imaging with new innovative techniques and technologies could reveal even more secrets of supermassive black holes, both big and small.

☆ Peculiar dead white dwarf star has two faces
▼ + stars: | 2023-07-24 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —Astronomers have made a first-of-its-kind discovery — a white dwarf star with two completely different faces. White dwarfs are burnt remains of dead stars. The newly discovered white dwarf has two sides, one made of hydrogen and the other made of helium. Researchers have nicknamed the star Janus, for the Roman god of transition, which has two faces. “We might have possibly caught one such white dwarf in the act.”As the white dwarf cools over time, the heavier and lighter materials may mix together.

☆ An experiment that reaches across the galaxy has 'heard' an invisible sea of ripples in space-time for the first time. It's surprisingly loud.

Those ripples are probably the distant thunder of countless collisions between supermassive black holes, throughout space and time. He predicted that the intense gravity of extremely massive objects, like black holes, warps the fabric of space-time. The NSF funded the 15-year experiment, which is called the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). Supermassive black holes are thought to exist at the center of every galaxy. Her lab runs computer models of merging supermassive black holes to predict how they behave and what signals they send out into space.

☆ Scientists spot a planet that shouldn’t exist

CNN —A Jupiter-like planet located 520 light-years from Earth may be an unlikely survivor after its host star had a temper tantrum. The gas planet is known as 8 UMi b and was named Halla after its initial discovery by Korean astronomers in 2015. The exoplanet orbits a giant star larger than our sun named Baekdu, located in the Ursa Minor, or “Little Bear,” constellation. Halla orbits Baekdu at a distance about half that between the Earth and the sun at 0.46 astronomical units, or 42,759,659 miles (68,815,020 kilometers). While our solar system only has one star, many stars across the universe exist in binary pairs.

☆ Humans have to get in the way of AI to make it more responsible
▼ + stars: | 2023-04-17 | by ( Emilia David | ) www.businessinsider.com time to read: +4 min

Humans are key to responsible AI. Calls to pause AI development centered around the need to make sure we were building responsible AI. But some Big Tech companies laid off responsible AI employees as part of the great cost-cutting sweeping the industry, possibly undermining the greatest tool against unfettered, unchecked AI. Those moves come right as society has come to understand what can happen if AI escapes its guardrails, making AI ethics more important than ever. Here's why humans will help bring responsible AI to fruition.

☆ Webb telescope takes striking image of planet Uranus
▼ + stars: | 2023-04-07 | by ( Taylor Nicioli | ) edition.cnn.com time to read: +4 min

CNN —The James Webb Space Telescope has captured a new stunning image of ice giant Uranus, with almost all its faint dusty rings on display. Uranus has 13 known rings, with 11 of them visible in the new Webb image. A November Hubble image of Uranus (left) captured the planet's bright polar cap, while the recent Webb image displayed more detail, with a subtle enhanced brightness at the cap's center. With the exact mechanism behind the haze unknown, scientists are studying the polar cap using telescope images such as this new Webb image. In this new Webb image, similar to other recent images by the Hubble Space Telescope, storm clouds can be seen at the edge of the polar cap.

☆ Ghostly flying 'whirlpool' that appeared above Hawaii could be leftover SpaceX rocket fuel

A Japanese telescope captured footage of the anomaly after a SpaceX navigation satellite launch. "The Subaru-Asahi Star Camera captured a mysterious flying spiral over Maunakea, Hawai`i," the Subaru Telescope said on Twitter on January 19. SpaceX launches a Falcon 9 rocket carrying a pair of television broadcasting satellites at Cape Canaveral, Florida. Michael Weekes Jr./ReutersThis isn't the first time a spiral has been spotted in the sky after a SpaceX launch. The SpaceX rocket is also known for the "space jellyfish" it often paints across the sky as it climbs through the atmosphere.
