Astronomers observe two stars so close to each other that they will end up merging into a supermassive star

A study of "MY Camelopardalis" binary system, published in the journal Astronomy & Astrophysics, shows that the most massive stars are made up by merging with other smaller stars, as predicted by theoretical models.

People with “purpose” spend less time in the hospital
Science Focus
original post »Preventive health care is a powerful tool for keeping medical costs down. Contraception is cheaper than pregnancy and childbirth; a cholesterol test is cheaper than a triple bypass. It is therefore in society’s interest to encourage the use of preventive health care services like cancer screening, especially for elderly people in aging populations. Increased use of preventive health care also leads to healthier, longer-lived people.
Unfortunately, people aren’t particularly good about preventive health care; not even half of all people over the age of 65 in the US are up to date with recommended preventive services. How can we do better?
A recent PNAS study identified one factor that could help: the more that people feel like they have a purpose in life, the more likely they are to use preventive health care. Purpose was also found to be associated with a lower likelihood of needing overnight hospital visits—possibly as a result of improved health care.

Our Milky Way Galaxy arcs over a desolate landscape in this fantastic panoramic night skyview. The otherworldly scene looks across the arid, eroded terrain of the Valle de la Luna in the Chilean Atacama desert. Just along the horizon are lights from San Pedro, Chile, as well as the small villages of Socaire and Toconao, and a torturous winding road from the city of Calama to San Pedro. Taken on October 18th, the five panel mosaic also features the four galaxies easily visible from our fair planet's dark sky regions. At the far left, satellite galaxies known as the Large and Small Magellanic Clouds are framed by their terrestrial namesakes. Much fainter and at the right, beyond the Milky Way's central bulge, is the Andromeda Galaxy. The most distant in view, Andromeda lies some 2.5 million light-years away.

Butterfly Nebula in Scorpius Constellation Rectangular Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: peel off, galaxies and stars, stellar winds, btbgneb, butterfly nebula, bug nebula, scorpius constellation, ngc 6302, sculptured gas clouds
Galaxies, Stars and Nebulae series NGC 6302, more popularly called the Bug Nebula or the Butterfly Nebula, lies within our Milky Way galaxy, roughly 3,800 light-years away in the constellation of Scorpius.
The central dying star cannot be seen because it's hidden within a doughnut-shaped ring of dust, which appears as a dark band pinching the nebula in the centre. The thick dust belt constricts the star's outflow, creating the classic "bipolar" or hourglass shape displayed by some planetary nebulae.
The nebula's reddish outer edges are largely due to light emitted by nitrogen, which marks the coolest gas visible in the picture. The white-coloured regions are areas where light is emitted by sulphur. These are regions where fast-moving gas overtakes and collides with slow-moving gas that left the star at an earlier time, producing shock waves in the gas (the bright white edges on the sides facing the central star).

Monogram Celestial Bauble - SXP1062 space picture Round Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: monogram initials, sculptured gas clouds, hot young stars, star incubator, star galaxies, outer space picture, sxp1062, supernova remnant, small magellanic cloud, deep space astronomy, star factory, smc
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 on the left is a star factory and on the right is the pulsar. Known as SXP 1062, it's the bright white source located on the right-hand side of the image in the middle of the diffuse blue emission inside a red shell. The diffuse X-rays and optical shell are both evidence for a supernova remnant surrounding the pulsar. The optical data also displays spectacular formations of gas and dust in a star-forming region on the left side of the image. A comparison of the Chandra image with optical images shows that the pulsar has a hot, massive companion.
Astronomers are interested in SXP 1062 because the Chandra and XMM-Newton data show that it is rotating unusually slowly - about once every 18 minutes. (In contrast, some pulsars are found to revolve multiple times per second, including most newly born pulsars.) This relatively leisurely pace of SXP 1062 makes it one of the slowest rotating X-ray pulsars in the SMC.
Two different teams of scientists have estimated that the supernova remnant around SXP 1062 is between 10,000 and 40,000 years old, as it appears in the image. This means that the pulsar is very young, from an astronomical perspective, since it was presumably formed in the same explosion that produced the supernova remnant.

Helix Nebula, Beautiful Stars in the Galaxy Wall Decal
Here's a great wall decal featuring a beautiful image from deep space
tagged with: astronomy, celestial bodies, crab nebula, space, galaxy, twinkle, planets, stars, science, geek, physics, cosmos, big bang theory, hubble, telescope, exploration, orion nebula, hubble telescope, spitzer telescope, messier object, milky way, natural science, natural sciences, natural world, nebula, nobody, outer space, physical science, sciences, space exploration and research, taurus, zodiac, ngc 3603, emission nebula, universe, constellation, night sky, hubb
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. You can personalize the design further if you'd prefer, such as by adding your name or other text, or adjusting the image - just click 'Customize' to see all the options.
