Twin Jet Nebula: The wings of the butterfly

more »
The shimmering colours visible in this NASA/ESA Hubble Space Telescope image show off the remarkable complexity of the Twin Jet Nebula. The new image highlights the nebula's shells and its knots of expanding gas in striking detail. Two iridescent lobes of material stretch outwards from a central star system. Within these lobes two huge jets of gas are streaming from the star system at speeds in excess of one million kilometers per hour.

Can America cope with a resurgence of tropical disease?

Science Focus

original post »

One rainy Friday morning in March 2015, Dr. Laila Woc-Colburn saw two patients with neurocysticercosis (a parasitic infection of the brain) and one with Chagas disease, which is transmitted by insects nicknamed ‘kissing bugs.’ Having attended medical school in her native Guatemala, she was used to treating these kinds of diseases. But she was not in Guatemala anymore—this was Houston, Texas.

For half a day each week, one wing of the Smith Clinic’s third floor in Houston is transformed into a tropical medicine clinic, treating all manner of infectious diseases for anyone who walks through the door. Since it opened in 2011, Woc-Colburn and her colleagues have treated everything from dengue and chikungunya to river blindness and cutaneous leishmaniasis. Their patients are not globetrotting travelers, bringing exotic diseases back home. The Smith Clinic is a safety net provider, the last resort for healthcare for people on low incomes and without insurance. Many of their patients haven’t left the Houston area for years.

This suggests that what Woc-Colburn sees in the clinic may be just the leading edge of a gathering crisis. Diseases once associated with ‘elsewhere’ are increasingly being found in the southern states of the USA. Infectious disease physician Peter Hotez was so concerned that he founded a school of tropical medicine at the Baylor College of Medicine in Houston, well within the territory that Hotez argues is one of the world’s ten hotspots for so-called neglected tropical diseases.

Monogram Omega Nebula - Our Amazing Universe Oval Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: awesome astronomy images, omgneb, star forming regions, ngc 6618, omega nebula, inspirational, heavens, uplifting, initials, monogrammed, messier 17, european southern observatory, eso, vista, initialled, monogram, monograms

Galaxies, Stars and Nebulae series A great outer space picture featuring a three-colour composite image of the Omega Nebula (Messier 17, or NGC 6618), based on images obtained with the EMMI instrument on the ESO 3.58-metre New Technology Telescope at the La Silla Observatory. North is down and East is to the right in the image. It spans an angle equal to about one third the diameter of the Full Moon, corresponding to about 15 light-years at the distance of the Omega Nebula. The three filters used are B (blue), V ("visual", or green) and R (red).

Dumbbell Nebula in Taurus Oval Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: awesome astronomy images, inspirational, dmbblneb, vulpecula constellation, intense ultraviolet radiation, messier 27 ngc 6853, heavens, stars, dumbbell nebula, the fox constellation, european southern observatory, eso, vista

Galaxies, Stars and Nebulae series A great photo from deep space featuring the Dumbbell Nebula - also known as Messier 27 or NGC 6853. It's a typical planetary nebula and is located in the constellation Vulpecula (The Fox).

The distance is rather uncertain, but is believed to be around 1,200 light-years. It was first described by the French astronomer and comet hunter Charles Messier who found it in 1764 and included it as no. 27 in his famous list of extended sky objects.

Despite its class, the Dumbbell Nebula has nothing to do with planets. It consists of very rarefied gas that has been ejected from the hot central star (well visible on this photo), now in one of the last evolutionary stages. The gas atoms in the nebula are excited (heated) by the intense ultraviolet radiation from this star and emit strongly at specific wavelengths.

This image is the beautiful by-product of a technical test of some FORS1 narrow-band optical interference filters. They only allow light in a small wavelength range to pass and are used to isolate emissions from particular atoms and ions.

In this three-colour composite, a short exposure was first made through a wide-band filter registering blue light from the nebula. It was then combined with exposures through two interference filters in the light of double-ionized oxygen atoms and atomic hydrogen. They were colour-coded as “blue”, “green” and “red”, respectively, and then combined to produce this picture that shows the structure of the nebula in “approximately true” colours.
