Stained sections of lung tissue from the Flickr set ‘Pulmonary Pathology’ by Yale Rosen: (1) nests of neuroendocrine tumor cells; (2) ‘foci of benign-appearing spindle-shaped and oval cells’ (3) acid-fast stain of an infection by Mycobacterium avium-intracellulare, a relative of tuberculosis.

personally, i am normally pretty grossed out by biology, but these samples are striking.

84 Million Stars: Peering into the Galactic Heart: Big Pic

Astronomers have cataloged 84 million stars at the heart of the Milky Way galaxy using an enormous cosmic photo snapped by a telescope in Chile, a view that is billed as the largest survey ever of the stars in our galaxy’s core.

The staggering 9-gigapixel picture was created with data gathered by the Visible and Infrared Survey Telescope for Astronomy (VISTA), an instrument at the European Southern Observatory’s Paranal Observatory in northern Chile. The zoomable image is so large that it would measure 30 feet long by 23 feet tall (9 by 7 meters) if printed with the resolution of a typical book, researchers said.

The huge new picture probes the Milky Way's central bulge, a concentration of ancient stars found near the core of most spiral galaxies. Getting good looks at this region is not an easy task.

"Observations of the bulge of the Milky Way are very hard because it is obscured by dust," said co-author Dante Minniti, also of Pontificia Universidad Catolica de Chile. "To peer into the heart of the galaxy, we need to observe in infrared light, which is less affected by the dust."

The Most Mind-Blowing Space Spirals: Photos

  1. We’ve all heard of supernovae, but what are “recurrent novae”?

    In the case of the binary star system RS Ophiuchi, a small but dense white dwarf star orbits with a large, puffy red giant that is shedding huge quantities of matter. This matter is blasted into space in the form of a strong stellar wind, forming a spiral.

    Interestingly, in this star system, the white dwarf captures some of the gas from its companion star, gradually accumulating it.

    Once the gas reaches a critical mass and temperature, a massive explosion occurs, wiping out the expanding spiral. The process then repeats every 20 years or so.
  2. In 2010, the Hubble Space Telescope imaged a ghostly pinwheel spiral surrounding a binary star system called LL Pegasi.

    This bizarre cosmic phenomenon is caused by one of the stars dying, venting huge amounts of gas and dust into space. As the stars orbit one another every 800 years, the material expands into space like water being sprayed from a spinning garden sprinkler.
  3. Meet R Sculptoris, a dying star that is shedding its outer layers of gas, generating a beautiful spiral of radio emissions. This amazing sight was captured by the newly commissioned Atacama Large Millimeter Array (ALMA) in the Chilean desert.

    Although rare, this kind of space spiral isn’t unprecedented. In fact, there have been several spirals seen in recent years that have excited, spooked, but, above all, awed onlookers — here are a few of the most memorable.

Hubble Mosaic Pays Tribute to Van Gogh

One night, Harvard astronomer Alex Parker was camped out at the telescope for a spot of star-gazing, and found himself facing a long, dry period of waiting for the clouds to clear. To pass the time, he started playing around with various images from the Hubble Space Telescope, and ended up assembling them into a colorful mosaic.

love this!

sound familiar? it should. the sign is in the National Archives circa 1917-19 — i.e. World War I.


  • 1. but it with thought
  • 2. cook it with care
  • 3. use less wheat & meat
  • 4. buy local foods
  • 5. serve just enough
  • 6. use what is left

Don’t waste it!

A Head of State, and a Boy’s Touching Request

From the NYTimes:

For decades at the White House, photographs of the president at work and at play have hung throughout the West Wing, and each print soon gives way to a more recent shot. But one picture of President Obama remains after three years.

Our Incredible Infrared Universe

This all-sky image has been constructed from a mosaic of observations captured by NASA’s Wide-field Infrared Explorer (WISE). The observations, as released in a new atlas and catalog of the entire infrared sky on March 14, includes over half a billion stars, galaxies and other objects.
