NASA Astronomy Picture of the Day:

Is this what will become of our Sun? Quite possibly. The first hint of our Sun's future was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, one of the brightest planetary nebulae on the sky and visible with binoculars toward the constellation of the Fox (Vulpecula). It takes light about 1000 years to reach us from M27, featured here in colors emitted by sulfur (red), hydrogen (green) and oxygen (blue). We now know that in about 6 billion years, our Sun will shed its outer gases into a planetary nebula like M27, while its remaining center will become an X-ray hot white dwarf star. Understanding the physics and significance of M27 was well beyond 18th century science, though. Even today, many things remain mysterious about planetary nebulas, including how their intricate shapes are created.

NASA Astronomy Picture of the Day:

What glows there? The answer depends: sea or sky? In the sea, the unusual blue glow is bioluminescence. Specifically, the glimmer arises from Noctiluca scintillans, single-celled plankton stimulated by the lapping waves. The plankton use their glow to startle and illuminate predators. This mid-February display on an island in the Maldives was so intense that the astrophotographer described it as a turquoise wonderland. In the sky, by contrast, are the more familiar glows of stars and nebulas. The white band rising from the artificially-illuminated green plants is created by billions of stars in the central disk of our Milky Way Galaxy. Also visible in the sky is the star cluster Omega Centauri, toward the left, and the famous Southern Cross asterism in the center. Red-glowing nebulas include the bright Carina Nebula, just right of center, and the expansive Gum Nebula on the upper right.

Memorial Day honors all service members who lost their lives while in service to the United States, during peace and war. It is a time to reflect on those who made the ultimate sacrifice for our country.

    "Soldiers Memorial Day"
   Hymn by Mary B. C. Slade

When flow’ry Summer is at hand,
And Spring has gemm’d the earth with bloom,
We hither bring, with loving hand,
Bright flow’rs to deck our soldier’s tomb.

                  (Chorus)
Gentle birds above are sweetly singing
O’er the graves of heroes brave and true;
While the sweetest flow’rs we are bringing,
Wreath’d in garlands of red, white and blue.

They died our country to redeem,
And from the loving earth we bring
The wealth of hill, and vale, and stream,
Our grateful land’s best offering

                 (Chorus)
With snowy hawthorn, clusters white,
Fair violets of heav’nly blue,
And early roses, fresh and bright,
We wreathe the red, and white, and blue.

But purer than the fairest flowers,
We strew above the honored dead,
The tender changeless love of ours,
That decks the soldier’s lowly bed.

                   (Chorus)
We bend and kiss the precious sod,
Swift fall our tears the graves above
Oh! Brothers! from the hills of God,
Look down and see our changeless love.

Written by Mary B. C. Slade in 1870, two years after Gen. John A. Logan first declared May 30th a Memorial Day for decorating the graves of fallen soldiers. Music to her words was written by Perkins, W. O. (William Oscar). In 1968, Congress passed the Uniform Monday Holiday Act, which established Memorial Day as the last Monday in May. The change went into effect in 1971. Read about the Origins of Memorial Day

This asteroid has a moon. The robot spacecraft Galileo on route to Jupiter in 1993 encountered and photographed two asteroids during its long interplanetary voyage. The second minor planet it photographed, 243 Ida, was unexpectedly discovered to have a moon. The tiny moon, Dactyl, is only about 1.6 kilometers across and seen as a small dot on the right of the sharpened featured image. In contrast, the potato-shaped Ida is much larger, measuring about 60 kilometers long and 25 km wide. Dactyl is the first moon of an asteroid ever discovered -- now many asteroids are known to have moons. The names Ida and Dactyl are from Greek mythology.

Gliding through the outer Solar System, in 1989 the Voyager 2 spacecraft looked toward the Sun to find this view of most distant planet Neptune and its moon Triton together in a crescent phase. The elegant image of ice-giant planet and largest moon was taken from behind just after Voyager's closest approach. It could not have been taken from Earth because the most distant planet never shows a crescent phase to sunward eyes. Heading for the heliopause and beyond, the spacecraft's parting vantage point also robs Neptune of its familiar blue hue.

It was reported this week, that Rob Graham Education Center, a K-8 school in Miami-Dade County, has restricted access to the poem "The Hill We Climb" written by Amanda Gorman and recited by her at President Joe Biden’s inauguration on January 20, 2021; becoming the sixth and youngest poet, at age twenty-two, to deliver a poetry reading at a presidential inauguration.

The school decided to remove access to the book for elementary grade students and to only allow access to the book to Middle School students, after one parent filed a formal complaint on the grounds that the poem was “not educational” and included indirect “hate messages", Read More at NPR and The Guardian. According to the American Library Association, nearly 2,600 titles were targeted for censorship in 2022, an increase of almost 40 percent from the previous year.

“The Hill We Climb,”

When day comes we ask ourselves,
where can we find light in this never-ending shade?
The loss we carry,
a sea we must wade
We’ve braved the belly of the beast
We’ve learned that quiet isn’t always peace
And the norms and notions
of what just is
Isn’t always just-ice
And yet the dawn is ours
before we knew it
Somehow we do it
Somehow we’ve weathered and witnessed
a nation that isn’t broken
but simply unfinished

We the successors of a country and a time
Where a skinny Black girl
descended from slaves and raised by a single mother
can dream of becoming president
only to find herself reciting for one
And yes we are far from polished
far from pristine
but that doesn’t mean we are
striving to form a union that is perfect
We are striving to forge a union with purpose
To compose a country committed to all cultures, colors, characters and
conditions of man

And so we lift our gazes not to what stands between us
but what stands before us
We close the divide because we know, to put our future first,
we must first put our differences aside
We lay down our arms
so we can reach out our arms
to one another
We seek harm to none and harmony for all
Let the globe, if nothing else, say this is true:
That even as we grieved, we grew
That even as we hurt, we hoped
That even as we tired, we tried
That we’ll forever be tied together, victorious
Not because we will never again know defeat
but because we will never again sow division

Scripture tells us to envision
that everyone shall sit under their own vine and fig tree
And no one shall make them afraid
If we’re to live up to our own time
Then victory won’t lie in the blade
But in all the bridges we’ve made
That is the promised glade
The hill we climb
If only we dare
It’s because being American is more than a pride we inherit,
it’s the past we step into
and how we repair it

We’ve seen a force that would shatter our nation
rather than share it
Would destroy our country if it meant delaying democracy
And this effort very nearly succeeded
But while democracy can be periodically delayed
it can never be permanently defeated
In this truth
in this faith we trust
For while we have our eyes on the future
history has its eyes on us
This is the era of just redemption
We feared at its inception
We did not feel prepared to be the heirs
of such a terrifying hour
but within it we found the power
to author a new chapter
To offer hope and laughter to ourselves

So while once we asked,
how could we possibly prevail over catastrophe?
Now we assert
How could catastrophe possibly prevail over us?
We will not march back to what was
but move to what shall be
A country that is bruised but whole,
benevolent but bold,
fierce and free
We will not be turned around
or interrupted by intimidation
because we know our inaction and inertia
will be the inheritance of the next generation
Our blunders become their burdens
But one thing is certain:
If we merge mercy with might,
and might with right,
then love becomes our legacy
and change our children’s birthright

So let us leave behind a country
better than the one we were left with
Every breath from my bronze-pounded chest,
we will raise this wounded world into a wondrous one
We will rise from the gold-limbed hills of the west,
we will rise from the windswept northeast
where our forefathers first realized revolution
We will rise from the lake-rimmed cities of the midwestern states,
we will rise from the sunbaked south
We will rebuild, reconcile and recover
and every known nook of our nation and
every corner called our country,
our people diverse and beautiful will emerge,
battered and beautiful
When day comes we step out of the shade,
aflame and unafraid
The new dawn blooms as we free it
For there is always light,
if only we’re brave enough to see it
If only we’re brave enough to be it

Galaxies of the Virgo Cluster are scattered across this nearly 4 degree wide telescopic field of view. About 50 million light-years distant, the Virgo Cluster is the closest large galaxy cluster to our own local galaxy group. Prominent here are Virgo's bright elliptical galaxies Messier catalog, M87 at bottom center, and M84 and M86 (top to bottom) near top left. M84 and M86 are recognized as part of Markarian's Chain, a visually striking line-up of galaxies on the left side of this frame. Near the middle of the chain lies an intriguing interacting pair of galaxies, NGC 4438 and NGC 4435, known to some as Markarian's Eyes. Of course giant elliptical galaxy M87 dominates the Virgo cluster. It's the home of a super massive black hole, the first black hole ever imaged by planet Earth's Event Horizon Telescope.

NASA Astronomy Picture of the Day:

The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its more familiar outlines are seen in the brighter central region of the nebula in this impressive wide-angle view. But this wide and deep image combining data from two telescopes also reveals its extremely faint outer halo. At an estimated distance of 3,000 light-years, the faint outer halo is over 5 light-years across. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. More recently, some planetary nebulae are found to have halos like this one, likely formed of material shrugged off during earlier episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of this halo to be 50,000 to 90,000 years. Visible on the right, some 50 million light-years beyond the watchful planetary nebula, lies spiral galaxy NGC 6552.

NASA Astronomy Picture of the Day:

Sometimes we witness the Moon moving directly in front of -- called occulting -- one of the planets in our Solar System. Earlier this month that planet was Jupiter. Captured here was the moment when Jupiter re-appeared from behind the surface of our Moon. The Moon was in its third quarter, two days before the dark New Moon. Now, our Moon is continuously half lit by the Sun, but when in its third quarter, relatively little of that half can be seen from the Earth. Pictured, the Moon itself was aligned behind the famous Lick Observatory in California, USA, on the summit of Mount Hamilton. Coincidentally, Lick enabled the discovery of a moon of Jupiter: Amalthea, the last visually detected moon of Jupiter after Galileo's observations.
