Avocado flower.

One of the things I love about searching through the botany archives is seeing how different fruits and vegetables grow.

What we’re reading

[ohstarstuff]

Galactic Center of Our Milky Way The Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory — collaborated to produce an unprecedented image of the central region of our Milky Way galaxy. Observations using infrared light and X-ray light see through the obscuring dust and reveal the intense activity near the galactic core. The center of the galaxy is located within the bright white region in the upper portion of the image. The entire image covers about one-half a degree, about the same angular width as the full moon. Each telescope’s contribution is presented in a different color:

Yellow represents the near-infrared observations of Hubble. They outline the energetic regions where stars are being born as well as reveal hundreds of thousands of stars.

Red represents the infrared observations of Spitzer. The radiation and winds from stars create glowing dust clouds that exhibit complex structures from compact, spherical globules to long, stringy filaments.

Blue and violet represents the X-ray observations of Chandra. X-rays are emitted by gas heated to millions of degrees by stellar explosions and by outflows from the supermassive black hole in the galaxy’s center. The bright blue blob toward the bottom of the full field image is emission from a double star system containing either a neutron star or a black hole.

Nearby Dust Clouds in the Milky Way

These opaque, dark knots of gas and dust are called “Bok globules,” and they are absorbing light in the center of the nearby emission nebula and star-forming region, NGC 281. The globules are named after astronomer Bart Bok, who proposed their existence in the 1940’s.

Bok hypothesized that giant molecular clouds, on the order of hundreds of light-years in size, can become perturbed and form small pockets where the dust and gas are highly concentrated. These small pockets become gravitationally bound and accumulate dust and gas from the surrounding area. If they can capture enough mass, they have the potential of creating stars in their cores; however, not all Bok globules will form stars. Some will dissipate before they can collapse to form stars. That may be what’s happening to the globules seen here in NGC 281.

I open my scuttle at night and see the far-sprinkled systems, And all I see multiplied as high as I can cipher edge but the rim of the farther systems.

Wider and wider they spread, expanding, always expanding, Outward and outward and forever outward.

My sun has his sun and round him obediently wheels, He joins with his partners a group of superior circuit, And greater sets follow, making specks of the greatest inside them. There is no stoppage and never can be stoppage, — Walt Whitman, Excerpt from Leaves of Grass (1855) (Photography credit: Chad Powell, Isle of Wight Milky Way Photography)

The Active Galactic Core of Galaxy NGC 1433

This detailed view shows the central parts of the nearby active galaxy NGC 1433. The dim blue background image, showing the central dust lanes of this galaxy, comes from the NASA/ESA Hubble Space Telescope. The coloured structures near the centre are from recent ALMA observations that have revealed a spiral shape, as well as an unexpected outflow, for the first time.
