NASA Astronomy Picture of the Day:

The city lights outshine the stars in the City That Never Sleeps. Who would have thought that the Milky Way could be visible in this sky? This image was taken with a filter that blocks most visible light, capturing instead only light in the near-infrared region of the electromagnetic spectrum (with lower energy than visible light). The astrophotographer's clever setup blocks most of the light pollution from the city: old incandescent light bulbs and some neon lights are still bright in the near-infrared, but fluorescent and LED light bulbs are not. Of course, stars are also bright in the near-infrared! This image is a reminder that we all live under the same sky, and astronomy allows all of us to learn more about humanity's place in the Cosmos.

White teatfish (Holothuria fuscogilva), Ras Muhammad National Park, Red Sea, Egypt. This species of sea cucumber, also known as white teeth, is found in shallow waters near islands and around coral reefs in the tropical waters of the Indo-Pacific ocean. Juvenile cucumbers live in shallower waters (such as inter-tidal zones) and then migrate to deeper waters as they mature. Adult cucumbers weigh between 2.4 and 4 kilograms. They are oval in shape and have a firm texture. This species cucumber has lateral papillae (teats) which are often buried in the sand. As it's consumed as a food and is part of a large commercial fishery across its range, it was listed as vulnerable on the IUCN Red List in 2010 due to overfishing.

I sought the wood in summer
When every twig was green;
The rudest boughs were tender,
And buds were pink between.
Light-fingered aspens trembled
In fitful sun and shade,
And daffodils were golden
In every starry glade.
The brook sang like a robin—
My hand could check him where
The lissome maiden willows
Shook out their yellow hair.

“How frail a thing is Beauty,”
I said, “when every breath
She gives the vagrant summer
But swifter woos her death.
For this the star dust troubles,
For this have ages rolled:
To deck the wood for bridal
And slay her with the cold.”

I sought the wood in winter
When every leaf was dead;
Behind the wind-whipped branches
The winter sun set red.
The coldest star was rising
To greet that bitter air,
The oaks were writhen giants;
Nor bud nor bloom was there.
The birches, white and slender,
In deathless marble stood,
The brook, a white immortal,
Slept silent in the wood.

“How sure a thing is Beauty,”
I cried. “No bolt can slay,
No wave nor shock despoil her,
No ravishers dismay.
Her warriors are the angels
That cherish from afar,
Her warders people Heaven
And watch from every star.
The granite hills are slighter,
The sea more like to fail;
Behind the rose the planet,
The Law behind the veil.”

NASA Astronomy Picture of the Day:

What a cosmic coincidence! In today’s image, Mars joins the Beehive cluster (M44 or Praesepe) below an auroral curtain and above a horizon of happy little trees near Lansjärv, Sweden. An eruption off the Sun reached Earth on October 10th, 2026 causing strong disturbances in Earth’s magnetic field. Energetic particles from the eruption collide with and energize the molecules in Earth’s atmosphere, which release that extra energy as the colorful aurora captured here. Auroras, or guovssahasat in North Sámi, is traditionally viewed with respect by the Sámi people indigenous to Sweden and other Arctic regions. Coincidentally, Mars appeared closest to the center of the Beehive cluster in the sky at the time. Although bees have been to space, the Beehive cluster is actually a swarm of young stars. Their rotation periods have helped humanity learn about how stars spin slower over time as they lose mass through their stellar winds.
