Gallery: Trippy biomedical images from the Wellcome Trust

Science Focus

original post »

The Wellcome Trust is one of the largest biomedical charities in the world. In addition to funding research itself, Wellcome has a mission to engage and inform the public about the biological sciences in general. One of its efforts in this area is the online science magazine Mosaic, which has provided a number of articles we've run on Ars. Another resource they provide is the Wellcome Image Library, which hosts over 40,000 biomedical images.

Each year, the Wellcome goes through the recent acquisitions, and picks some of the most visually striking. The results are the Wellcome Image Awards, which are given out annually to the best of the previous year's acquisitions. We're pleased to bring you a selection of the 20 winners; to see them all, visit the 2015 Gallery.

Ever feel a cat lick your skin? You can now see why it feels the way it did thanks to this cross-section of a cat's tongue. This image is only 3mm across, providing a sense of how fine the structure is.

Keyhole Nebula and Digitus Impudicus Rectangle Sticker

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

Keyhole Nebula and Digitus Impudicus Rectangle Sticker

tagged with: kndigimp, peel off, galaxies and stars, keyhole nebula, carina nebula, massive stars, hubble space telescope, digitus impudicus, complex structure

Galaxies, Stars and Nebulae series Details of a mysterious, complex structure within the Carina Nebula (NGC 3372) are revealed by this image of the 'Keyhole Nebula, ' obtained with the Hubble Space Telescope. The picture is a montage assembled from four different April 1999 telescope pointings with Hubble's Wide Field Planetary Camera 2, which used six different colour filters. The picture is dominated by a large, approximately circular feature, which is part of the Keyhole Nebula, named in the 19th century by Sir John Herschel. This region, about 8000 light-years from Earth, is located adjacent to the famous explosive variable star Eta Carinae, which lies just outside the field of view toward the upper right. The Carina Nebula also contains several other stars that are among the hottest and most massive known, each about 10 times as hot, and 100 times as massive, as our Sun.

Voorwerpjes in Space

Mysterious Hanny's Voorwerp, Dutch for "Hanny's Object", is really enormous, about the size of the Milky Way Galaxy and glowing strongly in the greenish light produced by ionized oxygen atoms. It is thought to be a tidal tail of material left by an ancient galaxy merger, illuminated and ionized by the outburst of a quasar inhabiting the center of distant spiral galaxy IC 2497. Its exciting 2007 discovery by Dutch schoolteacher Hanny van Arkel while participating online in the Galaxy Zoo project has since inspired a search and discovery of eight more eerie green cosmic features. Imaged in these panels by the Hubble Space Telescope, all eight appear near galaxies with energetic cores. Far outside their associated galaxies, these objects are also likely echoes of quasar activity, illuminated only as light from a core quasar outburst reaches them and ultimately fading tens of thousands of years after the quasar outburst itself has faded away. Of course a galaxy merger like the impending merger of our own Milky Way and the Andromeda Galaxy, could also trigger the birth of a quasar that would illuminate our distant future version of Hanny's Voorwerp. Tomorrow's picture: rings and shadows

Celestial Bauble, Nebula N90 and Pulsar SXP1062 Wrapping Paper

Get your out-of-this-world gift wrap here! Perfect for Christmas gifts for anyone who is fascinated by what the universe holds in store for us!

Celestial Bauble, Nebula N90 and Pulsar SXP1062 Wrapping Paper

tagged with: sculptured gas clouds, hot young stars, star galaxies, outer space picture, supernova remnant, star factory, small magellanic cloud, smc, celestial bauble, hrbstslr sxp1062, star incubator

Galaxies, Stars and Nebulae series: In this composite image, X-rays from Chandra and XMM-Newton have been colored blue and optical data from the Cerro Tololo Inter-American Observatory in Chile are colored red and green. The flowering shape is a star factory and the bright blue star is the pulsar, known as SXP 1062. Astronomers are interested in SXP 1062 because it's spinning unusually slowly - about once every 18 minutes. (In contrast, some pulsars are found to revolve up to 1000 times per second)
