New cosmic photos of galactic "arcs and streaks" in space were released on Tuesday by NASA's James Webb Telescope. The galaxies are bending space and time in a phenomenon known as gravitational lensing. The SDSS J1226+2149 galaxy cluster shown in this newest photo is around 6.3 billion light years away, in the constellation Coma Berenices, according to the ESA. The James Webb Space Telescope's first deep field infrared image, released July 11, 2022. The light from the MACS0647-JD system is bent and magnified by the massive gravity of galaxy cluster MACS0647.

PRETORIA/CAPE TOWN, March 31 (Reuters) - South Africans took to the streets of Pretoria and Cape Town on Friday to protest against a Ugandan law passed last week that makes it a criminal offence to be openly LGBTQ. Singing and waving flags, demonstrators called on Uganda's president, Yoweri Museveni, not to sign it. "Queer people don't owe anyone anything, but we also deserve to live just like everyone else.

South Africa's relatively wealthy, developed economy and nearly three decades of political stability helped drive industry growth and draw in reinsurers. And they are now tightening the conditions of their agreements with insurance companies. Reinsurers are also pushing insurance companies to include so-called "named perils" in policies rather than offering blanket cover for catastrophes. Grid failure would plunge South Africa into a nationwide blackout that could last weeks.

Two huge coronal holes, dozen of times the size of the Earth, have appeared on the sun. These coronal holes can spew solar winds at 1.8 million mph toward our planet, which can cause stunning auroras and disrupt satellites. Coronal holes aren't actually holes in the sunA coronal hole rotates across the face of the sun, streaming solar wind towards Earth, February 1, 2017. Coronal holes happen in the "corona," the atmosphere of the sun, and can only be seen in UV or X-ray light. We could see this month's coronal holes again next monthThe coronal hole came into view as the sun rotated.

☆ An 'ultramassive' black hole has been discovered that's 33 billion times the mass of the sun

They estimate this black hole is 30 billion times bigger than our sun. That would make it one of the biggest black holes ever discovered. This black hole may remain one of the biggest holes ever discovered because physicists think black holes can't grow much bigger than that, Nightingale said. The technique could unveil 'inactive' black holesThe discovery of this black hole pushes back the limits of cosmology, Nightingale told the BBC. "How do you form a black hole this big in just 13 billion years of the universe's existence?"

☆ The solar system was hit with a gamma-ray burst so bright, it blinded scientists' equipment in space
▼ + stars: | 2023-03-29 | by ( Chris Panella | Jessica Orwig | ) www.businessinsider.com time to read: +5 min

Our solar system was hit by a gamma-ray burst so bright, it blinded space equipment and telescopes. A gamma-ray burst that recently hit our solar system was so bright, it temporarily blinded gamma-ray instruments in space, according to a NASA release. Scientists say the gamma-ray burst (GRB), the most powerful type of explosion in the universe, was 70 times brighter than any previously recorded event. What is a gamma-ray burst? Because it blinded space instruments, they couldn't accurately record it, so scientists weren't sure how bright the burst was when it first reached our planet.

☆ A second giant 'hole' has appeared on the sun, and it could send 1.8 million mph solar winds towards Earth
▼ + stars: | 2023-03-27 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +5 min

These 'holes' can send 1.8 million mph solar winds towards Earth. As this first 'hole' begins rotating away from us, a new giant coronal hole — about 18 to 20 Earths' across — has come into view. Coronal holes release solar winds into space which can damage satellites and reveal stunning auroras if they reach the Earth. The 'hole' is positioned close to the sun's equatorThe coronal hole came into view as the sun rotated. The solar winds can blast very fast solar winds, with speeds of more than 800 kilometers per second, Verscharen said.

☆ Scientists explain alien comet 'Oumuamua's strange acceleration
▼ + stars: | 2023-03-23 | by ( Will Dunham | ) www.reuters.com time to read: +4 min

A new study has offered a more sober explanation - that 'Oumuamua's speed-up was due to the release of hydrogen gas as the comet warmed up in the sunlight. "The key finding is that 'Oumuamua may have started as a water-rich icy planetesimal broadly similar to solar system comets. "We don't know its place of origin but it was probably traveling through interstellar space for less than 100 million years. It had a reddish color consistent with the colors of many small bodies in the solar system. A second interstellar object, the comet 2I/Borisov, was discovered visiting our solar system in 2019.

☆ NASA's James Webb Space Telescope is so powerful it discovered sand storms on a planet 235 trillion miles away
▼ + stars: | 2023-03-22 | by ( Grace Eliza Goodwin | Morgan Mcfall-Johnsen | ) www.businessinsider.com time to read: +4 min

NASA's James Webb Space Telescope found sand storms on a planet hundreds of trillions of miles away. From its vantage point in space, Webb can peer at a distant world and analyze the entire infrared spectrum of starlight passing through the planet's atmosphere. The James Webb Space Telescope fully deploys its primary mirror during development at Northrop Grumman Space Systems in Redondo Beach, California. The spectrum Webb found on the planet VHS 1256 b, showing signatures of silicate clouds, water, methane, and carbon monoxide. That means the stars' light doesn't drown out the light of the planet, making it an ideal target for the Webb telescope.

The sun is sporting a giant coronal hole that could fit 20-30 Earths across, back-to-back. Coronal holes blast rapid solar winds into space that travel 500-800 kilometers per second. Coronal holes are cooler in temperature, so they don't glow as bright and therefore look black against the rest of the sun. In this case, the solar winds from this coronal hole are scheduled to reach Earth by the end of this week. But coronal holes — even large ones like this — are far less violent.

[1/5] Locals in the Chiradzulu district look at the damage on a road after mudslides and rockfalls in the area caused by the aftermath of Cyclone Freddy in Blantyre, Malawi, March 15, 2023. Most people heeded the warnings, knowing from bitter experience the damage such storms could inflict: 600 people had died in Cyclone Idai in 2019. The storm was far more deadly in neighbouring Malawi, where at least 447 were killed as Freddy tore through the country's southern tip and inundated the main commercial hub of Blantyre. Mozambique and Malawi are among the poorest 8% of countries in the world, according to United Nations data. In the case of Freddy, this extra energy allowed the storm to pick up strength again and circle back to strike again.

While the storm had dissipated, rain continued to hamper rescue efforts as vehicles struggled on flooded roads. Lieutenant Colonel Dickens Kamisa, who participated in the search, said local authorities identified about eight areas where dead bodies should be buried and were using sniffer dogs to find trapped Malawians. Chifundo Chilimba, a local resident, told Reuters he could not find his family members as the depth of the mud was too deep. The United Nations World Food Programme (WFP) said it was providing food assistance by distributing partially pre-cooked food called corn-soya blend to displaced people. The storm had already killed about 27 people in Madagascar and Mozambique before it lashed Mozambique a second time.

March 14 (Reuters) - NASA on Tuesday said it had picked U.S. rocket builder Firefly Aerospace to put a lander on the moon's far side in 2026, under a nearly $112 million contract. "The commercial lander will deliver two agency payloads, as well as communication and data relay satellite for lunar orbit, which is an ESA (European Space Agency) collaboration with NASA," the U.S. space agency said. NASA handed a similar award of $73 million to spacecraft software firm Draper last year to deliver science and technology payloads to the far side of the moon in 2025. NASA awarded Cedar Park, Texas-based Firefly $93.3 million in 2021 to carry a suite of 10 science investigations and technology demonstrations to the moon in 2023.

☆ NASA image may show first-ever 'rogue' supermassive black hole, leaving a trail of newborn stars in its wake
▼ + stars: | 2023-03-09 | by ( Morgan Mcfall-Johnsen | ) www.businessinsider.com time to read: +8 min

A NASA Hubble image may show the first runaway supermassive black hole ever discovered. Astrophysicists have long theorized that black holes could "go rogue" or "run away," if other black holes pushed them out of their galaxies. But nobody has ever confirmed a black hole wandering through intergalactic space, much less a supermassive black hole going rogue. And while two galaxies colliding is the simplest explanation for a rogue black hole, that's not what seems to have happened here. Even though they're invisible, there's no reason to worry about rogue supermassive black holes sneaking up on us from other galaxies.

Astronaut Tim Peake said Europe's space agency avoids hiring people who want a one-way trip to Mars. The ESA wants people who are thoughtful and aware of risk mitigation, Peake told the FT.Peake added there were hurdles to overcome to reach Mars safely. During an interview with the Financial Times, published on Monday, Peake said those types of people were not who the space agency was looking for when hiring candidates. Peake told the FT that before getting there, "we have to get over the hurdles of getting to Mars safely." "I absolutely do not see us having a problem with getting to Mars and creating safe habitats on Mars," Peake told the FT.

☆ 5 times scientists thought they'd maybe discovered signs of extraterrestrial life but sadly didn't

Extraterrestrial life could exist, but mysterious objects in the sky aren't evidence of aliens. Scientists have thought they were close to discovering alien life a few times — none of it via UFOs. As the US discovered a flurry of UFOs — officially called "unidentified anomalous phenomena," or UAPs — in early February, Google searches for "extraterrestrial life" and "are aliens real" spiked. There have been incidents in the past where some researchers thought they'd come close to discovering signs of alien life — or even extraterrestrial intelligence — but none were UFOs. They dubbed the first interstellar object 'Oumuamua, which is a Hawaiian term meaning "a messenger from afar arriving first."

STELLENBOSCH, South Africa, Jan 16 (Reuters) - Flocks of white, black and brown ducks hunt for snails and bugs as they patrol the grapevines at a vineyard in South Africa's winemaking town of Stellenbosch, helping the owners steer clear of pesticides and synthetic fertilisers. Around 500 Indian runner ducks work as a natural pest control at the Vergenoegd Löw Wine Estate, but also entertain wine-quaffing tourists. "We call them the soldiers of the vineyards," the managing director of the estate, Corius Visser, told Reuters. Ducks are at the heart of the winery's regenerative agriculture practices, and specifically Indian runner ducks, which have long legs and an upright posture, meaning they are able to reach for snails between the leaves. Nutrient-rich manure from the ducks and other animals ensure the vineyard runs as sustainably as possible.
