Microbes collected by citizen scientists and grown on the International Space Station

Do microbes grow differently on the International Space Station than they do on Earth? Results from the growth of microbes collected by citizen scientists in Project MERCCURI indicate that most behave similarly in both places.

Hot lava flows in a parking lot—in upstate NY

Science Focus

original post »
Back in 2012, we pointed you to an awesome project at Syracuse University that creates artificial lava flows for science, art, and outreach. They don’t use some mild, room-temperature stand-in for lava, they do it the artisanal way:  melting small batches of basalt in a serious furnace and pouring out the incandescent results. I’ve been hoping to see it for myself ever since, and recently I got the chance to tag along with a group of volcanology students from Colgate University, who were designing and running their own lava experiments for class.

The furnace is surprisingly well-insulated, disguising the fact that it holds molten rock heated to over 1,200 degrees Celsius. It does emit a low, ominous roar, however, as it consumes natural gas to feed its fire. Once poured out, the lava quickly loses heat—it solidifies in just a minute or so, though it still remains incredibly hot long after. Because it solidifies so quickly, it forms amber-black volcanic glass riddled with bubbles of gas that were unable to escape.

The lava pours are as mesmerizing and beautiful as they are geologically exciting. And they’ve probably shocked many a bus rider staring dully out the window while passing the art building.

Sharp-eyed Alma spots a gigantic flare on famous red giant star

more »
Super-sharp observations with the telescope Alma have revealed what seems to be a gigantic flare on the surface of Mira, one of the closest and most famous red giant stars in the sky. Activity like this in red giants - similar to what we see in the Sun – comes as a surprise to astronomers. The discovery could help explain how winds from giant stars make their contribution to our galaxy’s ecosystem.

Saturn at Opposition

more »
Telescopic observers on Earth have been treated to spectacular views of Saturn lately as the ringed planet reached its 2015 opposition on May 23 at 0200 UT. Of course opposition means opposite the Sun in Earth's sky. So near opposition Saturn is up all night, at its closest and brightest for the year. These sharp images taken within hours of the Sun-Earth-Saturn alignment also show the strong brightening of Saturn's rings known as the opposition surge or the Seeliger Effect. Directly illuminated, the ring's icy particles cast no shadows and strongly backscatter sunlight toward planet Earth, creating the dramatic surge in brightness. Saturn currently stands in the sky not far from bright Antares, alpha star of the constellation Sagittarius.

Herschel's hunt for filaments in the Milky Way

more »
Observations with ESA's Herschel space observatory have revealed that our Galaxy is threaded with filamentary structures on every length scale. From nearby clouds hosting tangles of filaments a few light-years long to gigantic structures stretching hundreds of light-years across the Milky Way's spiral arms, they appear to be truly ubiquitous. The Herschel data have rekindled the interest of astronomers in studying filaments, emphasising the crucial role of these structures in the process of star formation.

Tarantula Nebula Star Forming Gas Cloud Sculpture iPad Mini Cases

Here's a great iPad case from Zazzle featuring a Hubble-related design. Maybe you'd like to see your name on it? Click to personalize and see what it's like!


tagged with: billowing interstellar gas clouds, awesome hubble images, star forming activity, star nurseries, tarantula nebula, triggering star formation, large magellanic cloud, hrbstslr tnlmcsfr, cosmological, galaxies, young hot stars

Galaxies, Stars and Nebulae series An awesome mobile phone shell featuring the Tarantula Nebula of the Large Magellanic Cloud, which is the nearest galaxy to the Milky Way, our galactic home. This Hubble image shows old stars from the distant past and rich, interstellar gas clouds feeding the formation of new ones. The most massive and hottest stars are intense, high-energy radiation sources and this pushes away what remains of the gas and dust, compressing and sculpting it. As the whorls and eddies clump and stretch it, gravity takes over and the birth of the next generation of new stars is triggered.

Monogram Fires of the Flame Nebula - in Orion Oval Sticker

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


tagged with: breathtaking astronomy images, hfflmnb, star forming, orion constellation, young stars clusters, orion the hunter, flame nebula, awesome space picture, monogram, initialled, heavens, orions belt, european southern observatory, eso, vista, initials, monogrammed, monograms

Galaxies, Stars and Nebulae series A gorgeous outer space picture featuring the spectacular star-forming region known as the Flame Nebula, or NGC 2024, in the constellation of Orion (the Hunter) and its surroundings.

In views of this evocative object in visible light the core of the nebula is completely hidden behind obscuring dust, but in this VISTA view, taken in infrared light, the cluster of very young stars at the object’s heart is revealed. The wide-field VISTA view also includes the glow of the reflection nebula NGC 2023, just below centre, and the ghostly outline of the Horsehead Nebula (Barnard 33) towards the lower right.

The bright bluish star towards the right is one of the three bright stars forming the Belt of Orion. The image was created from VISTA images taken through J, H and Ks filters in the near-infrared part of the spectrum.

The image shows about half the area of the full VISTA field and is about 40 x 50 arcminutes in extent. The total exposure time was 14 minutes and was the first to be released publicly from VISTA, the world’s largest survey telescope.
