Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: Where did that spot come from? Amateur astronomer Victor Buso was testing out a new camera on his telescope in 2016 when he noticed a curious spot of light appear -- and remain. After reporting this unusual observation, this spot was determined to be light from a supernova just as it was becoming visible -- in an earlier stage than had ever been photographed optically before. The discovery before and after images, taken about an hour apart, are shown in the inset of a more detailed image of the same spiral galaxy, NGC 613, taken by the Hubble Space Telescope. Follow-up observations show that SN 2016gkg was likely the explosion of a supergiant star, and Buso likely captured the stage where the outgoing detonation wave from the stellar core broke through the star's surface. Since astronomers have spent years monitoring galaxies for supernovas without seeing such a "break out" event, the odds of Buso capturing this have been compared to winning a lottery.

Explanation: What are these two bands in the sky? The more commonly seen band is the one on the right and is the central band of our Milky Way galaxy. Our Sun orbits in the disk of this spiral galaxy, so that from inside, this disk appears as a band of comparable brightness all the way around the sky. The Milky Way band can also be seen all year -- if out away from city lights. The less commonly seem band, on the left, is zodiacal light -- sunlight reflected from dust orbiting the Sun in our Solar System. Zodiacal light is brightest near the Sun and so is best seen just before sunrise or just after sunset. On some evenings in the north, particularly during the months of March and April, this ribbon of zodiacal light can appear quite prominent after sunset. It has recently been determined that zodiacal dust was mostly expelled by comets that have passed near Jupiter. Only on certain times of the year will the two bands be seen side by side, in parts of the sky, like this. Here the two streaks of light appear like the continuation of the banks of the Liver River into the sky. The featured panorama of consecutive exposures was recorded about three weeks ago in North Jutland, Denmark.

Singer-songwriter Kacey Musgraves has been pushing the boundaries of contemporary country music since releasing her remarkable, 2013 major label debut, Same Trailer, Different Park. She's back now with a new album and two new songs that solidify her place in the "new" Nashville sound by digging even deeper into sparkly, spikey pop. We've got one of the two new singles, "Butterflies," which she calls an "ode to the right person giving me wings and the first song I wrote after meeting my now husband." Hear that and a whole lot more on this week's mix of essential new songs.
In 2015, four years after singer Amy Winehouse's death, Universal Music U.K. CEO David Joseph announced that he'd destroyed all of her demo recordings in an attempt to prevent anyone from releasing them posthumously. Despite that, composer Gil Cang, who wrote songs for Winehouse early in her career, has posted a Winehouse track called "My Own Way" to YouTube.
We're one week into the 2018 contest and love what we're seeing. Submissions have already come in from all over the country featuring music and desks ofall varieties. With that, we'd like to take a moment to celebrate the first entry we received: Ian Bamberger's "A Privateer's Eyes."
Lee Ann Womack occupies rare terrain in country music. Though massively popular singles led to her commercial success and widespread recognition, these days, she's working on the fringes of the genre. Her 2017 record, The Lonely, The Lonesome & The Gone, evokes the country music of Womack's Texas upbringing as the daughter of a country radio DJ, name-checking Hank Williams and covering George Jones.
Skating Polly's music has skittered back and forth along the genre spectrum between alt-rock and what it calls "ugly pop." The band's lead single for The Make It All Show, "Queen for a Day," skews towards rock as it drips with punk sensibilities: from Kelli Mayo's snarling vocal performance to the simple and stripped down verses leading into the thrashing of guitars on the chorus.

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: Here comes Jupiter! NASA's robotic spacecraft Juno is continuing on its 53-day, highly-elongated orbits around our Solar System's largest planet. The featured video is from perijove 11, the eleventh time Juno has passed near Jupiter since it arrived in mid-2016. This time-lapse, color-enhanced movie covers about four hours and morphs between 36 JunoCam images. The video begins with Jupiter rising as Junoapproaches from the north. As Juno reaches its closest view -- from about 3,500 kilometers over Jupiter's cloud tops -- the spacecraft captures the great planet in tremendous detail. Juno passes light zones and dark belt of clouds that circle the planet, as well as numerous swirling circular storms, many of which are larger than hurricanes on Earth. After the perijove, Jupiter recedes into the distance, now displaying the unusual clouds that appear over Jupiter's south. To get desired science data, Juno swoops so close to Jupiter that its instruments may soon fail due to exposure to high levels of radiation. Because of this, in part, the Juno mission is currently schedule to conclude in mid-2018, at perijove 14, when the spacecraft will be directed to dive into Jupiter's atmosphere and melt.

AE Aurigae and the Flaming Star Nebula Image Credit & Copyright: Martin Pugh
Explanation: Why is AE Aurigae called the flaming star? For one reason, the surrounding nebula IC 405 is named the Flaming Star Nebula because the region seems to harbor smoke, even though nothing is on fire, including interior star AE Aurigae. Fire, typically defined as the rapid molecular acquisition of oxygen, happens only when sufficient oxygen is present and is not important in such high-energy, low-oxygen environments. The material that appears as smoke is mostly interstellar hydrogen, but does contain smoke-like dark filaments of carbon-rich dust grains. The bright star AE Aurigae is visible near the nebula center and is so hot it is blue, emitting light so energetic it knocks electrons away from atoms in the surrounding gas. When an atom recaptures an electron, light is emitted creating the surrounding emission nebula. The Flaming Star nebula lies about 1,500 light years distant, spans about 5 light years, and is visible with a small telescope toward the constellation of the Charioteer (Auriga).

Thousands and thousands of people across the country have come down with the flu this season, one of the worst in years.
If you’re part of the unfortunate multitude, you might be asking yourself when it’s OK to leave your sick bed and return to real life, including work.
NPR’s Madeline Sofia and Adam Cole put together a video in our Skunk Bear series that might help you figure it out.
Virginia Harrod survived breast cancer but developed lymphedema, which sent her to the hospital three times with serious infections. Luke Sharrett for NPR
During Virginia Harrod’s treatment for stage 3 breast cancer, she underwent a double mastectomy.
Surgeons also took out 16 lymph nodes from under her armpit and the area around her breast to determine how far the cancer had spread and whether she needed more treatment.
The removal of the lymph nodes, along with radiation therapy, put Harrod at risk for lymphedema, a painful and debilitating swelling of the soft tissue of the arms or legs.
The problem with her lymph system months after surgery was a direct result of her lifesaving cancer treatment. "Cancer was a piece of cake," Harrod tells NPR’s Patti Neighmond. "It was the lymphedema that almost killed me."

Shaorong Deng, who has cancer of the esophagus, is taking part in a study that Dr. Shixiu Wu says is the most advanced of its kind in China. Wu and his colleagues are testing the gene-editing technique called CRISPR as a treatment for cancer.
At least eight other Chinese studies of CRISPR for various forms of cancer are listed on a U.S. government website that serves as a research clearinghouse.
"China has made this a very high priority — a national priority to develop this" technology, says Dr. Carl June of the University of Pennsylvania. He worries the U.S. is falling behind China, in an echo of the early days of the space race: "It's kind of like Sputnik 2.0."
