A time-lapse video shows the sun getting more chaotic over the past four years. That's because solar activity could impact Earth, creating bursts of electromagnetic energy that can affect everything from the power grid to GPS signals. NOAA/InsiderAs solar activity ramps up, more sunspots and eruptions have been appearing on the sun's surface, sending solar winds into the universe that can hit our planet. Here's what this looks like:In the time-lapse video, solar flares appear as an intense brightening of a region on the sun. Meanwhile, the sun's surface appears gradually less homogenous, indicating more magnetic activity at the surface.

The sun looks spooky and mysterious in new images from the world's most powerful solar telescope. The Daniel K. Inouye Solar Telescope has been observing the sun from the Hawaiian island of Maui since it first opened in 2020. Its first video, below, showed roiling solar plasma, each cell the size of Texas. Dark "pores" on the solar surface indicate powerful magnetic fields, which are likely driving the dark threads visible in the atmosphere above. The bright yellow surface plasma cools until its density is so low that it drops below the surface, through the dark lanes between cells.

☆ Astronomers spot a sneak peek of Earth's death — a star swallowing a planet whole — for the first time
▼ + stars: | 2023-05-03 | by ( Morgan Mcfall-Johnsen | ) www.businessinsider.com time to read: +7 min

Astronomers discovered a distant star swallowing a planet for the first time ever. Swallowing the planet whole produced a burst of energy that expelled the star's outer layers, causing it to expand and brighten rapidly. Except for a veneer of dust, the star pretty much looked the same as it had before, one year after devouring its planet. The distant planet that just got absorbed by its star was about the size of Jupiter, which is more than 1,300 Earths. (It later turned out, this pre-eruption dust was material from the planet skimming the atmosphere of the star as it orbited closer and closer.)

☆ I've studied the sun for 23 years. Here's what happened during the last solar maximum and what to expect from this one.

Solar maximum is a peak in the sun's activity that happens around the middle of each solar cycle. Mathew OwensThe solar maximum represents a peak in solar activity when the sun's magnetic field reaches its strongest and most disordered and dynamic point. NASA/Solar Dynamics ObservatorySolar cycles typically last 11 years, and the solar maximum happens roughly in the middle of each cycle. The sun's magnetic field reaches peak strength during solar maximum, generating an increase in events like solar flares and coronal mass ejections. These bursts are around four times as likely to occur during a solar maximum than a solar minimum.

BEIJING, April 23 (Reuters) - China's Vice Foreign Minister Sun Weidong has lodged solemn representations with the South Korean ambassador over "erroneous" remarks by the South Korean president about Taiwan, China's foreign ministry said on Sunday. "The Taiwan issue is not simply an issue between China and Taiwan but, like the issue of North Korea, it is a global issue," Yoon said. Yoon's remarks are "totally unacceptable," Sun said, according to a Chinese foreign ministry statement. "The South Korean leader made no mention of the One China principle, but equated the Taiwan issue with the Korean Peninsula issue," Sun said. Sun's complaint followed criticism from the Chinese foreign ministry last week that South Korea should "prudently" handle matters related to Taiwan.

Life somehow managed to survive during this time called "Snowball Earth," and a new study offers a deeper understanding as to why. "Our study shows that, at least near the end of the Marinoan 'Snowball Earth' event, habitable areas extended to mid-latitude oceans, much larger than previously thought. And the Earth spiraled into Snowball Earth conditions," Virginia Tech geobiologist and study co-author Shuhai Xiao said. Multicellular organisms including red algae, green algae and fungi emerged before the Cryogenian and survived "Snowball Earth." "It is fair to say that the 'Snowball Earth' events were significant challenges to life on Earth," Xiao added.

[1/4] Former Taiwanese President Ma Ying-jeou gestures as he arrives at an airport in Shanghai, China March 27, 2023. Ma, in office from 2008-2016, is the first former or current Taiwanese president to visit China since the defeated Republic of China government fled to Taiwan in 1949 at the end of a civil war with the Communists. He is visiting amid heightened tension as Beijing uses political and military means to try and pressure democratically governed Taiwan into accepting Chinese sovereignty. Taiwan President Tsai Ing-wen has repeatedly offered talks with China, but has been rejected as China considers her a separatist. He and Chinese President Xi Jinping met in Singapore in 2015.

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.

☆ Intriguing moon water source found in glass beads from impacts
▼ + stars: | 2023-03-27 | by ( Will Dunham | ) www.reuters.com time to read: +4 min

The researchers see promise in obtaining water from the glass beads, perhaps through a heating process to release vapor that would then turn into liquid through condensation. "We can simply heat these glass beads to free the water stored in them," said planetary scientist and study co-author Hejiu Hui of Nanjing University in China. The glass beads were found to hold a water content of up to about 2,000 parts per million by weight. Hu said he believes that such impact glass beads are a common part of lunar soils, found globally and spread evenly. The interaction of the solar wind with lunar surface materials could sustain a water cycle on the moon, with the glass beads absorbing the water and acting as a repository for it, the researchers said.

That caused the Northern Lights, or aurora borealis, to make a rare appearance in skies across the US. The colorful lights were seen as far south as Arizona, much further than what was forecast. They normally occur in the Arctic, but powerful eruptions on the sun caused them to stretch as far south as Phoenix, Arizona before sunrise on Friday, according to images shared by photographers and skywatchers on social media. "Most people when they're seeing that far south... they're seeing it on the horizon," Young said. NWS La CrosseAnchorage, AlaskaAuroras in Anchorage, Alaska, on March 24, 2023.

For many Muslims, Ramadan means abstaining from food and drink while at work. So, how can non-Muslim colleagues be supportive, while also not accidentally making a micro-aggression toward someone who is observing Ramadan? At one office where Nasr worked, a boss privately asked her if she needed any special accommodations while observing Ramadan. Most Muslims use the Arabic phrase "Ramadan Mubarak," which translates to "have a blessed Ramadan" or "happy Ramadan, to greet each other. Plus, there are many other reasons why Muslims don't fast, like during illness or travel.

That motion, called convection, is what creates strong magnetic fields at the poles and smaller, local magnetic fields at the surface of the sun. That instability causes havoc in the magnetic fields at the surface of the sun, which become much more active. NASA/Solar Dynamics ObservatoryAs the magnetic fields become more confused, bigger sun spots can appear on the surface of the sun. As the sun's local magnetic fields get more tangled and crash into each other, they can explode. "The aurora oval that sits up over the northern and southern poles is a result of currents flowing in the Earth's atmosphere," Owens said.
