The Sombrero Galaxy in Infrared

(This image was shared by APoD on January 21, 2007.)

This floating ring is the size of a galaxy. In fact, it is part of the photogenic Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of Galaxies.

The dark band of dust that obscures the mid-section of the Sombrero Galaxy in optical light actually glows brightly in infrared light.
The below image shows the infrared glow, recorded by the orbiting Spitzer Space Telescope, superposed in false-color on an existing image taken by NASA's Hubble Space Telescope in optical light.

The Sombrero Galaxy, also known as M104, spans about 50,000 light years across and is located 28 million light-years from Earth at the southern edge of the rich Virgo cluster of Galaxies. Equivalent to 800 billion suns, Sombrero is one of the most massive objects in that group.

The hallmark of Sombrero is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy.
As seen from Earth, the galaxy is tilted nearly edge-on. We view it from just six degrees north of its equatorial plane. This rich system of globular clusters is estimated to be nearly 2,000 in number which is 10 times as many as in our Milky Way galaxy.

Similar to the clusters in the Milky Way, the ages range from 10-13 billion years old. Embedded in the bright core of M104 is a smaller disk, which is tilted relative to the large disk.
The HST paired with the Spitzer infrared telescope, offers this striking composite capturing the magnificence of the Sombrero galaxy.
In the Hubble view, the galaxy resembles a broad-rimmed Mexican hat, whereas in the Spitzer striking infrared view, the galaxy looks more like a bulls eye.

The full view provided by Spitzer shows the disk is warped, which is often the result of a gravitational encounter with another galaxy, and clumpy areas spotted in the far edges of the ring indicate young star forming regions. Spitzer detected infrared emission not only from the ring, but from the center of the galaxy as well, where there is a huge black hole believed to be a billion times more massive than our Sun.

M104 can be seen with a small telescope in the direction of the constellation Virgo.

Crescent Jupiter with the Great Red Spot

This image of a crescent Jupiter and the iconic Great Red Spot was created by a citizen scientist (Roman Tkachenko) using data from Juno's JunoCam instrument.
You can also see a series of storms shaped like white ovals, known informally as the "string of pearls."
Below the Great Red Spot a reddish long-lived storm known as Oval BA is visible.

The image was taken on Dec. 11, 2016 at 2:30 p.m. PST (5:30 p.m. EST), as the Juno spacecraft performed its third close flyby of Jupiter. At the time the image was taken, the spacecraft was about 285,100 miles (458,800 kilometers) from the planet.

Eurasian Jay (Garrulus glandarius)

The Eurasian jay (Garrulus glandarius) is a species of bird occurring over a vast region from Western Europe and north-west Africa to the Indian Subcontinent and further to the eastern seaboard of Asia and down into south-east Asia. Across its vast range, several very distinct racial forms have evolved to look very different from each other, especially when forms at the extremes of its range are compared.

The bird is called jay, without any epithets, by English speakers in Great Britain and Ireland. It is the original 'jay' after which all others are named.

Eurasian Jay feeds primarily on invertebrates such as caterpillars and beetles during the breeding and nesting seasons. It gleans from foliage in trees. But as other Corvidae, it also takes eggs and nestlings of several bird species.
During autumn and winter, it feeds on seeds and berries, chestnuts and acorns. One jay often caches acorns in winter (up to 3000 a month), by burying each acorn in the leaf litter or beneath low vegetation. It has learnt to know the green shoots of oak produced by the buried acorns. The next summer, it easily finds them and feeds the germinated acorn. It is a prolific planter of oaks!

Eurasian Jay usually flies fairly low and between trees. In flight, the white rump is very conspicuous. It performs undulating flight.
During migrations or movements in flocks, they climb high and move out with steady wing beats.

Breeding season varies according to the range.
Eurasian Jays have long-term pair-bonds and are solitary nesters.

Mars Then and Now

Two images of Mars taken over 100 years apart. The first was drawn by Eugene Antoniadi in 1894, the second is from Hubble during the close approach of Mars in 2003. It's interesting to see what they got right and what they got wrong.
Notably the extensive system of 'Martian Canals', which Percival Lowell was so adamant existed and proved the presence of Martians.

Actually, a hot debate topic of the late 1800s, several prominent astronomers including Percival Lowell not only claimed to see an extensive system of long straight canals on Mars, but used them to indicate that intelligent life exists there.

The relatively close opposition of 1894 was used to make drawings like the one digitally re-scaled on the below left.

In more modern times, the latest Mars opposition has allowed the Hubble Space Telescope to capture a picture of similar orientation. Comparison of the two images shows that large features were impressively recorded, but that an extensive system of long and straight canals just does not exist.

Satellites orbiting Mars have now shown conclusively that the red planet does indeed have surface features similar to canals, but that these are usually smaller, curved, and less extensive than that previously claimed. Real canyon systems like Noctis Labyrinthus are most likely cracks caused by surface stress.

Our Ability to Recognize Faces Improves from Infancy to Adulthood

A comparison of kid brains and grown-up brains may explain why our ability to recognize faces keeps getting better until about age 30.

Brain scans of 25 adults and 22 children showed that an area devoted to facial recognition keeps growing long after adolescence, researchers report in the journal Science.

The area didn't acquire more neurons, says Jesse Gomez, a graduate student in neurosciences at Stanford University and the study's lead author. Instead the brain region became more densely populated with the structures that connect and support neurons.

Understanding how facial recognition develops throughout childhood could make it easier to figure out why some people have difficulty recognizing faces, researchers say.

Gomez hopes to scan the brains of people with "face blindness," a disorder that can leave a person unable to recognize even familiar faces.

And Suzy Scherf, an assistant professor of psychology at Penn State University, wants to know whether people with autism, who often struggle to recognize faces, have abnormal development in the facial recognition area of their brains.

Great Rift Near the Center of the Milky Way

On November 10, 2016, APoD shared this stunning image about the Great Rift.

Let's try to learn more.

Over 100 telescopic image panels in this amazing vertical mosaic span about 50 degrees across the night sky.
They follow part of the Great Rift, the dark river of dust and molecular gas that stretches along the plane of our Milky Way Galaxy.
More precisely, the Great Rift (sometimes called the Dark Side, Dark Rift, or, less commonly, Dark River) is a series of overlapping, non-luminous, molecular dust clouds that are located between the Solar System and the Sagittarius Arm of the Milky Way Galaxy at a distance of about 100 parsecs or about 300 light years (2×10^15 miles or 3×10^15 kilometers) from Earth. The clouds are estimated to contain about 1 million solar masses of plasma and dust.

Start at top center and you can follow the galactic equator down through brighter stars in constellations Aquila, Serpens Cauda, and Scutum.
At the bottom is Sagittarius near the center of the Milky Way. Along the way you'll encounter many obscuring dark nebulae hundreds of light-years distant flanked by bands of Milky Way starlight, and the telltale reddish glow of starforming regions.

Notable Messier objects include The Eagle (M16) and Omega (M17) nebulae, the Sagittarius Star Cloud (M24), the beautiful Trifid (M20) and the deep Lagoon (M8).

Two New Missions to Explore the Early Solar System

NASA has selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system – a time less than 10 million years after the birth of our sun.

The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed to mission formulation, with the goal of launching in 2021 and 2023, respectively.

Lucy, a robotic spacecraft, will visit a target-rich environment of Jupiter’s mysterious Trojan asteroids. Scheduled to launch in October 2021, the spacecraft is slated to arrive at its first destination, a main asteroid belt, in 2025.
Then, from 2027 to 2033, Lucy will explore six Jupiter Trojan asteroids.

The Psyche mission will explore one of the most intriguing targets in the main asteroid belt – a giant metal asteroid, known as 16 Psyche, about three times farther away from the sun than is the Earth. The asteroid measures about 130 miles in diameter and, unlike most other asteroids that are rocky or icy bodies, it is thought to be comprised of mostly metallic iron and nickel, similar to Earth’s core.
The Psyche robotic mission is targeted to launch in October of 2023, arriving at the asteroid in 2030, following an Earth gravity assist spacecraft maneuver in 2024 and a Mars flyby in 2025.

NGC 1977: Running Man Nebula

NGC 1977 is one of the most-recognized highlights in the constellation of Orion.
Although classified as an open cluster embedded within nebulosity, this area just north of the Orion Nebula is generally recognized as the Running Man Nebula owing to the emission nebulosity at the center which is in the formation of a running man.

The cluster is approximately 1,500 light-years away and spans approximately 20' in diameter. It is dominated by a number of bright stars ranging from mag 4 to mag 6 and whose light reflects off gas in the immediate vicinity and thus leading to reflection nebulosity.

Two other reflection nebulae sitting on the shoulders of the humanoid figure have classifications within the NGC catalog, namely NGC 1975 to the east and NGC 1973 to the west. Also, an area of protostar formation to the south is known as Herbig-Haro 45.

Asteroid (226514) 2003 UX34 Is a Binary System

Arecibo and Goldston planetary radar observations of 250 m asteroid (226514) 2003 UX34 reveal it is a binary system!

The Minor Planet Center has classified 2003 UX34 as a "Potentially Hazardous Asteroid."

This gif demonstrates the orbit of the secondary object about the primary; each frame is a sum of 3 minutes of data.

NEA 2003 UX34 was discovered in October 2003 by Spacewatch at Kitt Peak. At its closest approach on January 2, 2017, it was within a distance 19 times the Earth-Moon distance.
