Underground magma ocean could explain Io's 'misplaced' volcanoes
more »
Tides flowing in a subsurface ocean of molten rock, or magma, could explain why Jupiter's moon Io appears to have its volcanoes in the 'wrong' place. New NASA research implies that oceans beneath the crusts of tidally stressed moons may be more common and last longer than expected.

Surprising giant ring-like structure in the universe
more »
(Phys.org)—Five billion light years is a distance almost inconceivable, even on a cosmic scale. To better illustrate the extent of this physical quantity, it's enough to say that 35,000 galaxies the size of our Milky Way are needed to cover that distance. Thanks to a surprising discovery made by a Hungarian-U.S. team of astronomers, now we know that a structure this big really exists in the observable universe.

Saturn Solar Eclipse Poster
Here's a great poster featuring a beautiful image from deep space
tagged with: space, astronomy, saturn, stars, planets, earth, cassini, sun, exploration, rings, moons
You may think that this is a fake image, but it is actually a real photo taken from the Cassini space craft of Saturn eclipsing the Sun. The rings glow brightly as the light filters through them and the reflect that light all the way around to the back of the planet creating a surreal effect. A special surprise in the photo is that, just to the left of the rings, that bright blue dot is Earth, where you're sitting right now. This is truly a fascinating and beautiful image.

Babies have a better moral compass when their parents are fair and just, too
Science Focus
original post »
University of Chicago Child Neurosuite
Understanding the difference between right and wrong is part of a cognitive toolkit that starts out early in life and grows in complexity. There are still countless mysteries about that growth: how much of the moral toolkit are babies born with? What pieces fall into place at what age? How does a baby's environment affect its moral cognition, and how does moral cognition affect behaviour?
A paper in this week's issue of PNAS builds on previous studies of infant morality to explore what happens in babies' brains while they watch social interactions. The authors also determine how these neural signals match up with their own behaviours and their parents' beliefs.
For the study, babies were shown animated characters that either helped or hindered each other. The researchers found that the babies had different neural readings depending on whether the interaction between the animated characters was prosocial or antisocial. They also found that the strength of this difference was linked to their parents' beliefs about justice. Children with a larger difference in their neural patterns were also more likely to reach for a toy of the helpful character later.

Monogram - Enlarged Region of The Omega Nebula Classic Round Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: stars, galaxies, astronomy, universe, outer space, envelope sealers, eroton, galaxies stars, gas clouds, star forming activity, green hydrogen, omega nebula m17, ultraviolet radiation, young massive stars, monogram initials, blue oxygen, red sulpher
Galaxies, Stars and Nebulae series Like the fury of a raging sea, this bubbly ocean of glowing hydrogen, oxygen, and sulphur gas lies in the extremely massive and luminous molecular nebula Messier 17.
This Hubble photograph captures a small region within Messier 17 (M17), a hotbed of star formation. M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the Sagittarius constellation.
Ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds and the warmed surfaces glow orange and red. The intense heat and pressure causes some material to stream away from the surface, creating the glowing veil of even hotter green-coloured gas that masks background structures. The colours in the image represent various gases. Red represents sulphur; green, hydrogen; and blue, oxygen.

Star Cluster Pismis 24, core of NGC 6357 Room Stickers
Here's a great wall decal featuring a beautiful image from deep space
tagged with: stars, galaxies, astronomy, wall decal, star cluster, pismis 24, sculpting ultaviolet ionisation, super massive stars, sclustpsms, nebula ngc 6357
Galaxies, Stars and Nebulae series The star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 that extends one degree on the sky in the direction of the Scorpius constellation. Part of the nebula is ionised by the youngest (bluest) heavy stars in Pismis 24. The intense ultraviolet radiation from the blazing stars heats the gas surrounding the cluster and creates a bubble in NGC 6357. The presence of these surrounding gas clouds makes probing into the region even harder. One of the top candidates for the title of "Milky Way stellar heavyweight champion" was, until now, Pismis 24-1, a bright young star that lies in the core of the small open star cluster Pismis 24 (the bright stars in the Hubble image) about 8,000 light-years away from Earth. Pismis 24-1 was thought to have an incredibly large mass of 200 to 300 solar masses. New NASA/ESA Hubble measurements of the star, have, however, resolved Pismis 24-1 into two separate stars, and, in doing so, have "halved" its mass to around 100 solar masses.

Cassiopeia is a constellation in the northern sky named after the vain queen Cassiopeia in Greek mythology. She was in the story Clash of the Titans and was the mother of Andromada. Because the constellation Cassiopeia lies in rich Milky Way star fields, it contains many deep sky objects, including open clusters and nebulae. This is the reason why it looks so stunning when photographed. Image curtesy of Nasa.

Carina Nebula in Argo Navis constellation Wall Decor
Here's a great wall decal featuring a beautiful image from deep space
tagged with: stars, galaxies, astronomy, wall decal, carina nebula, argos navis constellation, carina the keel, star formation, gas clouds, carnebngcttst, ngc 3372
Galaxies, Stars and Nebulae series Hubble's view of the Carina Nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology).
The original image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope's Advanced Camera for Surveys. The Hubble images were taken in the light of ionized hydrogen. Colour information was added with data taken at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.
