☆ Mirror Images: 4 Picture Books About Seeing Our Reflections
▼ + stars: | 2023-08-16 | by ( Sabrina Orah Mark | ) www.nytimes.com time to read: +1 min

Mirrors, throughout literature, are omens and traps. They are soft enough to walk through, like mist; they are riddles that shatter upon reflection; they are magic. And what they reflect back may not have anything to do with us, or if it does have to do with us it’s the hide to our seek. When read from front to back, the book imparts an essential message about being kind to your reflection. Each page is dappled with black ink, as if Zebra’s stripes have permeated the air of the grasslands she grazes, because don’t landscapes reflect the beings that inhabit them?

The Perseid meteor shower will reach its peak this weekend, according to the American Meteor Society. The shower began this year on July 14, and will continue until September 1, though not as many meteors will be visible after the peak. “Meteor showers result in beautiful streaks of light as debris passes through our atmosphere,” Schmoll said. So the less light around when observing the meteor shower means we are more likely to see fainter meteors.”You can catch several major meteor showers later this year, according to the American Meteor Society. They will reach their peak on the following dates:Orionids: October 21-21Southern Taurids: November 4-5Northern Taurids: November 11-12Leonids : November 17-18Geminids: December 13-14Ursids: December 21-22Autumnal equinoxThis year, the end of the Perseid meteor shower coincides with the meteorological start of the fall season in the Northern Hemisphere.

☆ NASA’s ‘shout’ restores communication with Voyager 2
▼ + stars: | 2023-08-04 | by ( Ashley Strickland | ) edition.cnn.com time to read: +3 min

CNN —Using a long-shot “shout” maneuver, the Voyager mission team at NASA has reestablished communication with Voyager 2 after losing contact with the spacecraft, which has been operating for nearly 46 years. Commands sent to Voyager 2 on July 21 accidentally caused the spacecraft’s antenna to point 2 degrees away from Earth. One radio antenna is located at Goldstone near Barstow, California, the second near Madrid, and the third near Canberra, Australia. It’s not the first time that the aging twin probes — Voyager 1 and Voyager 2, both launched in 1977 — have experienced issues. Voyager 1, which is nearly 15 billion miles (24 billion kilometers) from Earth, continues to operate as expected and communicate with the Deep Space Network.

CNN —The Voyager mission team at NASA has been able to detect a signal from Voyager 2 after losing contact with the spacecraft, which has been operating for nearly 46 years. One radio antenna is located at Goldstone near Barstow, California, the second near Madrid, and the third near Canberra, Australia. “We are now generating a new command to attempt to point the spacecraft antenna toward Earth,” Dodd said. Along the way, both Voyager 1 and 2 have encountered unexpected issues and dropouts, including a seven-month period where Voyager 2 and the Deep Space Network couldn’t communicate in 2020. Meanwhile, Voyager 1, which is nearly 15 billion miles (24 billion kilometers) from Earth, continues to operate as expected and communicate with the Deep Space Network.

☆ Antarctica is missing an Argentina-sized amount of sea ice – and scientists are scrambling to figure out why
▼ + stars: | 2023-07-30 | by ( Sophie Tanno | ) edition.cnn.com time to read: +5 min

Antarctic sea ice has fallen to unprecedented lows for this time of year. Every year, Antarctic sea ice shrinks to its lowest levels towards the end of February, during the continent’s summer. In mid-July, Antarctica’s sea ice was 2.6 million square kilometers (1 million square miles) below the 1981 to 2010 average. While natural climate variability affects the sea ice, many scientists say climate change may be a major driver for the disappearing ice. A lack of sea ice could also have significant impacts on its wildlife, including krill on which many of the region’s whales feed, and penguins and seals that rely on sea ice for feeding and resting.

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.

Instead, moderate, natural warming led to large-scale melting and sea level rise of more than 1.4 meters (4.6 feet), according to the report published Thursday in the journal Science. This would have significant impacts on sea level rise. The potential implications for sea level rise are enormous, Tammy Rittenour, a professor from Utah State University and study co-author said in a statement. “We are looking at meters of sea level rise, probably tens of meters. “The current greenhouse gas emission-driven warming may reduce the Greenland ice sheet faster than forecast,” he told CNN.

In 2020, the global value of sun care products was $10.7 billion. Millennial skin care favorites — Paula’s Choice ($34), Glossier ($25), Drunk Elephant ($34) — have all created their own luxury daily sunscreens. “I think there is a more pervasive media representation of (the benefits of) wearing sunscreen, like preventing aging and preventing skin cancer,” Waldman said in a phone interview. In a study published in 2021, scientists found that more children in middle and high school were wearing sunscreen, a trend researchers partially attributed to social media. Meanwhile, young influencers on TikTok parade their multi-step skin care routines, with many featuring products like retinoids and AHAs, celebrated for their role in minimizing signs of aging.

These were Keston Park’s problems — not mine and probably not Tom Cruise’s. Tom Cruise, as he and I both now knew, was most likely secretly living at another estate I had turned up in my research — one that was even closer to the airport. Tom Cruise would be crazy not to live here, I thought as I stroked the soft, sun-warmed mane of a little white donkey. Except, upon my arrival at the end of an idyllic woodland stroll, I discovered that Cruise did not live there either. I righted the gnome and ambled on, in search of another public footpath that would, I hoped, lead me to where Cruise actually lived.

Every 11 years or so, the sun experiences periods of low and high solar activity, which is associated with the amount of sunspots on its surface. Over the course of a solar cycle, the sun will transition from a calm to an intense and active period. During the peak of activity, called solar maximum, the sun’s magnetic poles flip. A solar activity spikeThe current solar cycle, known as Solar Cycle 25, has been full of activity, more so than expected. The solar storms generated by the sun can affect electric power grids, GPS and aviation, and satellites in low-Earth orbit.

It’s the first day of your beach vacation and you stayed out in the sun a little (or a lot) too long. A sunburn is your skin cells’ reaction to damage from the sun’s ultraviolet radiation. In a first-degree sunburn, the top layer of skin, called the epidermis, is injured, resulting in redness, pain and swelling. Second-degree sunburns are more severe because the next layer of skin, called the dermis, is also harmed. On darker skin, sunburns are harder to notice at first because redness is less apparent.

Wildfire smoke turns the air orange for the same reason clear air makes the sky look blue — it has to do with what kind of tiny particles are in the air, how many there are and what wavelength color they block. As it passes through the Earth’s atmosphere, the sun’s light hits all of the molecules and particles in the air. Wildfire smoke blocks the shorter wavelengths — like yellow, green and blue — leaving just the red and orange to pass through. The light has more atmosphere to pass through before it gets to our eyes, which amplifies the colors and how thick the smoke looks in the air.

☆ How Solar Wind Flows From the Sun Like Water From a Shower Head
▼ + stars: | 2023-06-07 | by ( Kenneth Chang | ) www.nytimes.com time to read: 1 min

High-speed particles spew out of the sun like water from a shower head, scientists reported on Wednesday. Data from the Parker Space Probe, a NASA spacecraft that launched in 2018 and is now swooping in to gather readings of the sun’s outer atmosphere, or corona, is providing clues about how the sun generates the solar wind — a million-miles-per-hour stream of electrons, protons and other charged particles rushing outward into the solar system. The solar wind research ties into a mystery that has long perplexed scientists: Why is the corona, where temperatures soar to millions of degrees, so much hotter than the surface of the sun, which is a relatively cool 10,000 degrees Fahrenheit? The Parker probe is named after Eugene N. Parker, a University of Chicago astrophysicist who first predicted the existence of the solar wind in 1958.

The slower solar wind, located in the same plane of the solar system as Earth, flows at a calmer 249 miles per second (400 kilometers per second). This flip causes the coronal holes to appear across the sun’s surface and release bursts of solar wind directly toward Earth. JHU Applied Physics Laboratory/NASA's Goddard Space Flight CenterUnderstanding the source of the solar wind can help scientists better predict space weather and solar storms that can affect Earth. Fortunately, Parker Solar Probe and a separate mission, Solar Orbiter, are perfectly poised to observe the sun’s powerful, dynamic forces at play. “There was some consternation at the beginning of the solar probe mission that we’re going to launch this thing right into the quietest, most dull part of the solar cycle,” Bale said.
