NASA Astronomy Picture of the Day:

These two galaxies are far far away, 12 million light-years distant toward the northern constellation of the Great Bear. On the left, with grand spiral arms and bright yellow core is spiral galaxy M81, some 100,000 light-years across. On the right marked by red gas and dust clouds, is irregular galaxy M82. The pair have been locked in gravitational combat for a billion years. Gravity from each galaxy has profoundly affected the other during a series of cosmic close encounters. Their last go-round lasted about 100 million years and likely raised density waves rippling around M81, resulting in the richness of M81's spiral arms. M82 was left with violent star forming regions and colliding gas clouds so energetic the galaxy glows in X-rays. In the next few billion years, their continuing gravitational encounters will result in a merger, and a single galaxy will remain.

NASA Astronomy Picture of the Day:

The pre-dawn hours of May 3rd were moonless as grains of cosmic dust streaked through southern skies above Reunion Island. Swept up as planet Earth plowed through dusty debris streams left behind periodic Comet 1/P Halley, the annual meteor shower is known as the Eta Aquarids. This inspired exposure captures a bright aquarid meteor flashing left to right over a sea of clouds. The meteor streak points back to the shower's radiant in the constellation Aquarius, well above the eastern horizon and off the top of the frame. Known for speed Eta Aquarid meteors move fast, entering the atmosphere at about 66 kilometers per second, visible at altitudes of 100 kilometers or so. Then about 6 light-minutes from Earth, the pale greenish coma and long tail of Comet C/2020 F8 SWAN were not to be left out of the celestial scene, posing above the volcanic peaks left of center. Now in the northern sky's morning twilight near the eastern horizon Comet SWAN has not become as bright as anticipated though. This first time comet made its closest approach to planet Earth only two days ago and reaches perihelion on May 27.

Difficult times can bring out the best in people—and as the coronavirus spreads across the nation, an epidemic of kindness has followed in its wake. Despite the challenge of social distancing, people are finding creative ways to stand by each other, even while standing apart.

Shortly after the “stay home” order, Kristan McCary of Ajax Café sprang into action. Her Port Hadlock restaurant announced free meals for curbside pickup on social media: “For as long as we are able, the Ajax will be serving no cost meals for those in need.” Soon thereafter, she offered free delivery to the housebound.

Maryland teenagers Matt Casertano and Dhruv Pai organized a grocery delivery service for senior citizens. After volunteering to shop for their own elderly neighbors, they realized they could help on a larger scale. Now seniors in their community can email shopping lists, and a nearby volunteer gets the groceries and leaves them at the front door.

Citizens nationwide have stepped up to feed our frontline healthcare providers. In D.C., Elena Tompkins and Sarah Cannova collect donations to buy meals for delivery to hospital workers, which also helps struggling restaurants. In Bremerton, Ed Van Gil started making large batches of home-cooked meals and personally delivering them to healthcare facilities—and when word of his good deed spread, a group of community volunteers joined in.

Many people also rely on spiritual sustenance, and churches have adapted by holding services inspired by drive-in theatres. The congregation assembles in cars, and the sermon—often delivered from “pulpits” designed for maximum visibility—is broadcast to their radios. In Ohio, Pastor Frank Carl stands 25 feet high in a scissor lift, while in Wisconsin, Pastor John Hanson preaches from atop a dump truck.

As countless celebrations for graduations, weddings, and birthdays have been cancelled, drive-by parades of family and friends have become the new norm. New Jersey native Charles Swody’s 100th birthday was no exception. The World War II veteran and retired local Fire Chief was honored with a festive motorcade through his neighborhood, complete with a fire engine in the lead—and his wife of 78 years at his side.

Such is the generosity and resilience of the human spirit. We’ve learned how to stay close, even from a safe distance. We’ve learned to spread love, not fear. And we’ve learned that no matter how far apart we are, we’re all in this together.

NASA Astronomy Picture of the Day:

In infrared, Jupiter lights up the night. Recently, astronomers at the Gemini North Observatory in Hawaii, USA, created some of the best infrared photos of Jupiter ever taken from Earth’s surface, pictured. Gemini was able to produce such a clear image using a technique called lucky imaging, by taking many images and combining only the clearest ones that, by chance, were taken when Earth's atmosphere was the most calm. Jupiter’s jack-o’-lantern-like appearance is caused by the planet’s different layers of clouds. Infrared light can pass through clouds better than visible light, allowing us to see deeper, hotter layers of Jupiter's atmosphere, while the thickest clouds appear dark. These pictures, together with ones from the Hubble Space Telescope and the Juno spacecraft, can tell us a lot about weather patterns on Jupiter, like where its massive, planet-sized storms form.

NASA Astronomy Picture of the Day:

Where are all of these meteors coming from? In terms of direction on the sky, the pointed answer is the constellation of Small Harp (Lyra). That is why the famous meteor shower that peaks every April is known as the Lyrids -- the meteors all appear to came from a radiant toward Lyra. In terms of parent body, though, the sand-sized debris that makes up the Lyrid meteors come from Comet Thatcher. The comet follows a well-defined orbit around our Sun, and the part of the orbit that approaches Earth is superposed in front of Lyra. Therefore, when Earth crosses this orbit, the radiant point of falling debris appears in Lyra. Featured here, a composite image containing over 33 meteors (can you find them all?) from last month's Lyrid meteor shower shows several bright meteors that streaked over a shore of Seč Lake in the Czech Republic. Also visible are the bright stars Vega and Altair, the planet Jupiter, and the central band of our Milky Way Galaxy. Notable APOD Submissions: Lyrid Meteor Shower 2020

Tell me father.
Please tell me why,
all men who live,
may soon die.
The time for death
comes in many ways.
Some leave at night
others, in simple days.
Life is a precious journey,
towards a star,
of our choosing,
that's what we are.
