A twist on planetary origins: Meteorites were byproducts of planetary formation, not building blocks
more »
Meteors that have crashed to Earth have long been regarded as relics of the early solar system. These craggy chunks of metal and rock are studded with chondrules -- tiny, glassy, spherical grains that were once molten droplets. Scientists have thought that chondrules represent early kernels of terrestrial planets: As the solar system started to coalesce, these molten droplets collided with bits of gas and dust to form larger planetary precursors.

Helix Nebula in space Poster
Here's a great poster featuring a beautiful image from deep space
tagged with: space, astronomy, nasa, nebula, galaxy, original, quality, custom, helix, eye of god, best, unique, affordable, photography, gift, popular, science, planet, space exploration, solar system, outer space, deep space, space age, space design, space image, space travel, space shuttle, space telescope, space and time, space race, space center, space time, universe, mystical, laureen, laureenr
This infrared image from NASA's Spitzer Space Telescope shows the Helix Nebula, a cosmic starlet often photographed by amateur astronomers for its vivid colors and eerie resemblance to a giant eye. The nebula, located about 700 light-years away in the constellation Aquarius, belongs to a class of objects called planetary nebulae. Discovered in the 18th century, these colorful beauties were named for their resemblance to gas-giant planets like Jupiter. Planetary nebulae are the remains of stars that once looked a lot like our sun. When sun-like stars die, they puff out their outer gaseous layers. These layers are heated by the hot core of the dead star, called a white dwarf, and shine with infrared and visible colors. Our own sun will blossom into a planetary nebula when it dies in about five billion years. In Spitzer's infrared view of the Helix nebula, the eye looks more like that of a green monster's. Infrared light from the outer gaseous layers is represented in blues and greens. The white dwarf is visible as a tiny white dot in the center of the picture. The red color in the middle of the eye denotes the final layers of gas blown out when the star died. The brighter red circle in the very center is the glow of a dusty disk circling the white dwarf (the disk itself is too small to be resolved). This dust, discovered by Spitzer's infrared heat-seeking vision, was most likely kicked up by comets that survived the death of their star. Before the star died, its comets and possibly planets would have orbited the star in an orderly fashion. But when the star blew off its outer layers, the icy bodies and outer planets would have been tossed about and into each other, resulting in an ongoing cosmic dust storm. Any inner planets in the system would have burned up or been swallowed as their dying star expanded. So far, the Helix nebula is one of only a few dead-star systems in which evidence for comet survivors has been found.

The math of organ donation: Kidneys are an NP-hard problem
Science Focus
original post »We're bilaterally symmetric organisms—we've got matching bits on our left and right side. But many critical organs are present in only a single copy (hello heart) or we need both to function optimally (see: lungs). The kidneys are rare exceptions, as your body gets by just fine with only a single one. That has enabled people to become living kidney donors, with both the donor and recipient continuing life with one kidney.
Often, in cases where someone needs a transplant, there is a relative willing to make this sacrifice but is unable to do so because they aren't a close enough tissue match (which would lead to the organ's rejection by its new host's immune system). Separately, there are some rare individuals who are simply willing to donate a kidney to an unknown recipient. So the medical community has started doing "donation chains," where a group of donor-recipient pairs are matched so that everyone who receives a kidney has a paired donor that gives one to someone else.
That, as it turns out, has created its own problem: given a large pool of donors and recipients, how do you pull a set of optimized donor chains out? It turns out that the optimization belongs to a set of mathematical problems that are called NP-hard, making them extremely difficult to calculate as the length of the chain goes up. But now, some researchers have developed algorithms that can solve the typical challenges faced by hospitals with the processing power of a desktop computer.

Earth-sized planets discovered by Kepler may really be Earth-like
Science Focus
original post »Ever since exoplanets were first discovered in the 1990s, astronomers have dreamed of finding an Earth-like planet amongst the stars. Better detection techniques have allowed us to find smaller and smaller exoplanets. But when we spot a planet beyond our Solar System, does “Earth-sized” really mean “Earth-like?” A new study presented at this week’s American Astronomical Society meeting shows that the smallest exoplanets are much more likely to be similar to Earth than we thought.
Astronomers, led by graduate student Courtney Dressing of the Harvard-Smithsonian Center for Astrophysics, used the HARPS-North instrument to study Kepler-93b, an exoplanet 1.5 times the radius of the Earth.
The latest study shows that Kepler-93b, an exoplanet with a diameter of 1.5 times that of Earth, has a mass of 4.02 times that of Earth. The mass and volume give a density, from which we can infer that this little exoplanet has a composition very similar to Earth’s.

The Hunter, the Bull, and Lovejoy
more »
Heading north, Comet Lovejoy (C/2014 Q2) is putting on its best show for comet watchers now, with moonlight absent from mid-January's early evening skies. An easy binocular target and just visible to the unaided eye from dark sites, the comet sweeps across the constellation Taurus the Bull in this deep night skyscape. The starry scene was captured just two days ago on January 12, from Jackson Hole, Wyoming, planet Earth. In fact, the head of Taurus formed by the V-shaped Hyades star cluster points toward Lovejoy at the right. The comet's greenish coma and tail streaming in the anti-sunward direction also seem to have been shot from Orion's bow. You can spot the familiar stars of the nebula rich constellation of the Hunter on the left, and follow this link to highlight Comet Lovejoy in the wide field of view.

The Heart and Soul nebulae are seen in this infrared mosaic from NASA's Wide-field Infrared Survey Explorer, or WISE. Also visible near the bottom of this image are two galaxies, Maffei 1 and Maffei 2. Maffei 1 is the bluish elliptical object and Maffei 2 is the spiral galaxy. All four infra-red detectors aboard WISE were used to make this image. Colour is representational: blue and cyan represent infra-red light at wavelengths of 3.4 and 4.6 microns, which is dominated by light from stars. Green and red represent light at 12 and 22 microns, which is mostly light from warm dust.
