Close Encounters: Comet Siding Spring Seen Next to Mars
Get larger image formats
This is a photo composite of the encounter of Comet Siding Spring with Mars on October 19, 2014. Separate Hubble Space Telescope images of Mars and the comet have been combined together into a single picture. This is a composite image because a single exposure of the stellar background, Comet Siding Spring, and Mars would be problematic because the objects are all moving with respect to each other and the background stars. Hubble can only track one planetary target at a time. Also, Mars is actually 10,000 times brighter than the comet, and the exposure here has been adjusted so that details on the Red Planet can be seen.

The science of autumn colors
Science Focus
original post »
Whether you make a point of going on leaf-peeping excursions or just enjoy the turning leaves shading your street, you probably wonder what the story is behind the autumn palette of maples, oaks, birches, and other deciduous trees. The answer lies in biochemistry.
The cycle of colors in the leaves of deciduous trees is influenced by weather and temperature (more on that later), but one of the primary drivers is the lengths of nights and days, which govern a tree's growth cycle. As nights start getting longer, deciduous trees start to form what are called abscission layers at the intersection...

All the diseases you should worry about at least as much as Ebola
Science Focus
original post »
Ebola is serious business in the United States, particularly if you're in the media. Turn on a TV and you have 24-hour Ebola coverage on three cable networks, with anchors breathlessly discussing everything from your pet's role in spreading Ebola to any number of alerts, threats, and false alarms for air travel passengers.
The Ebola virus has killed exactly one person in a country of over 316 million.
While worldwide it's a true threat (the WHO just called it "the most severe, acute health emergency seen in modern times"), Ebola has yet to pose the same kind of danger in the States. Indeed...

Name, M106 Spiral Galaxy, Canes Venatici Gift Wrap 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!
tagged with: star galaxies, outer space picture, deep space astronomy, hubble galaxy photography, supermassive black hole, messier 106, spiral arms, constellation canes venatici, hunting dog stars, hrftpraz m106cv, m106cv, seyfert ii galaxy
Galaxies, Stars and Nebulae series Messier 106 (also known as NGC 4258) is a spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy, which means that due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center.

Galaxies in Pegasus
more »
This wide, sharp telescopic view reveals galaxies scattered beyond the stars and faint dust nebulae of the Milky Way at the northern boundary of the high-flying constellation Pegasus. Prominent at the upper right is NGC 7331. A mere 50 million light-years away, the large spiral is one of the brighter galaxies not included in Charles Messier's famous 18th century catalog. The disturbed looking group of galaxies at the lower left is well-known as Stephan's Quintet. About 300 million light-years distant, the quintet dramatically illustrates a multiple galaxy collision, its powerful, ongoing interactions posed for a brief cosmic snapshot. On the sky, the quintet and NGC 7331 are separated by about half a degree.

Two families of comets found around nearby star: Biggest census ever of exocomets around beta pictoris
more »
The HARPS instrument at ESO’s La Silla Observatory in Chile has been used to make the most complete census of comets around another star ever created. Astronomers have studied nearly 500 individual comets orbiting the star Beta Pictoris and has discovered that they belong to two distinct families of exocomets: old exocomets that have made multiple passages near the star, and younger exocomets that probably came from the recent breakup of one or more larger objects.

Name, Stephans Quintet deep space star galaxies Gift Wrap 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!
tagged with: star galaxies, outer space picture, deep space astronomy, galaxy cluster, galaxy quintet, hicksons compact group, spiral galaxy, eliptical galaxy, stkcg, stephans quintet
Galaxies, Stars and Nebulae series A clash among members of a famous galaxy quintet reveals an assortment of stars across a wide color range, from young, blue stars to aging, red stars.
This portrait of Stephan's Quintet, also known as Hickson Compact Group 92, was taken by the new Wide Field Camera 3 (WFC3) aboard NASA's Hubble Space Telescope. Stephan's Quintet, as the name implies, is a group of five galaxies. The name, however, is a bit of a misnomer. Studies have shown that group member NGC 7320, at upper left, is actually a foreground galaxy about seven times closer to Earth than the rest of the group.
Three of the galaxies have distorted shapes, elongated spiral arms, and long, gaseous tidal tails containing myriad star clusters, proof of their close encounters. These interactions have sparked a frenzy of star birth in the central pair of galaxies. This drama is being played out against a rich backdrop of faraway galaxies.
The image, taken in visible and near-infrared light, showcases WFC3's broad wavelength range.
The colors trace the ages of the stellar populations, showing that star birth occurred at different epochs, stretching over hundreds of millions of years. The camera's infrared vision also peers through curtains of dust to see groupings of stars that cannot be seen in visible light.
NGC 7319, at top right, is a barred spiral with distinct spiral arms that follow nearly 180 degrees back to the bar. The blue specks in the spiral arm at the top of NGC 7319 and the red dots just above and to the right of the core are clusters of many thousands of stars. Most of the quintet is too far away even for Hubble to resolve individual stars.
Continuing clockwise, the next galaxy appears to have two cores, but it is actually two galaxies, NGC 7318A and NGC 7318B. Encircling the galaxies are young, bright blue star clusters and pinkish clouds of glowing hydrogen where infant stars are being born. These stars are less than 10 million years old and have not yet blown away their natal cloud. Far away from the galaxies, at right, is a patch of intergalactic space where many star clusters are forming.
NGC 7317, at bottom left, is a normal-looking elliptical galaxy that is less affected by the interactions.
Sharply contrasting with these galaxies is the dwarf galaxy NGC 7320 at upper left. Bursts of star formation are occurring in the galaxy's disk, as seen by the blue and pink dots. In this galaxy, Hubble can resolve individual stars, evidence that NGC 7320 is closer to Earth.
NGC 7320 is 40 million light-years from Earth. The other members of the quintet reside 290 million light-years away in the constellation Pegasus.
These farther members are markedly redder than the foreground galaxy, suggesting that older stars reside in their cores. The stars' light also may be further reddened by dust stirred up in the encounters.
Spied by Edouard M. Stephan in 1877, Stephan's Quintet is the first compact group ever discovered.
WFC3 observed the quintet in July and August 2009. The composite image was made by using filters that isolate light from the blue, green, and infrared portions of the spectrum, as well as emission from ionized hydrogen.
These Hubble observations are part of the Hubble Servicing Mission 4 Early Release Observations. NASA astronauts installed the WFC3 camera during a servicing mission in May to upgrade and repair the 19-year-old Hubble telescope.
