Holometer extends limit on knowable universe

more »

The Holometer experiment is sensitive to gravitational waves at frequencies in the range of a million cycles per second. Thus it addresses a spectrum not covered by experiments such as the Laser Interferometer Gravitational-Wave Observatory, which searches for lower-frequency waves to detect massive cosmic events such as colliding black holes and merging neutron stars.

Our sun came late to the Milky Way's star-birth party

more »

Astronomers compiled a story of our Milky Way's growth by studying galaxies similar in mass to our galaxy, found in deep surveys of the universe. Stretching back more than 10 billion years, the census contains nearly 2,000 snapshots of Milky Way-like galaxies.

Our Sun Came Late to the Milky Way's Star-Birth Party



Get larger image formats

Our Sun missed the stellar "baby boom" that erupted in our young Milky Way galaxy 10 billion years ago. During that time the Milky Way was churning out stars 30 times faster than it does today. Our galaxy was ablaze with a firestorm of star birth as its rich reservoir of hydrogen gas compressed under gravity, creating myriad stars. But our Sun was not one of them. It was a late "boomer," arising 5 billion years later, when star birth had plunged to a trickle.

Saturn Solar Eclipse Posters

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.

Stellar Nursery R136 in the Tarantula Nebula Rectangle Sticker

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


tagged with: galaxies, dorneblmc, stellar nursery, 30 doradus nebula, large magellanic cloud, amazing hubble images, tarantula nebula, r136, star cluster, astronomy pictures, massive stars

Galaxies, Stars and Nebulae series Hundreds of brilliant blue stars wreathed by warm, glowing clouds in appear in this the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus (or Tarantula) Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way.
There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus. Many of the diamond-like icy blue stars are among the most massive stars known. Several of them are over 100 times more massive than our Sun. These hefty stars are destined to pop off, like a string of firecrackers, as supernovas in a few million years. The image, taken in ultraviolet, visible, and red light by Hubble's Wide Field Camera 3, spans about 100 light-years.
The movement of the LMC around the Milky Way may have triggered the massive cluster's formation in several ways. The gravitational tug of the Milky Way and the companion Small Magellanic Cloud may have compressed gas in the LMC. Also, the pressure resulting from the LMC plowing through the Milky Way's halo may have compressed gas in the satellite. The cluster is a rare, nearby example of the many super star clusters that formed in the distant, early universe, when star birth and galaxy interactions were more frequent.
The LMC is located 170,000 light-years away and is a member of the Local Group of Galaxies, which also includes the Milky Way. The Hubble observations were taken Oct. 20-27, 2009. The blue color is light from the hottest, most massive stars; the green from the glow of oxygen; and the red from fluorescing hydrogen.

Physicists show 'quantum freezing phenomenon' is universal

more »

(Phys.org)—Physicists who work on quantum technologies are always looking for ways to manage decoherence, which occurs when a quantum system unavoidably interacts with the surrounding environment. In the past few years, scientists have discovered that some quantum correlations can be "frozen" in a constant state and remain that way in the presence of noise, potentially offering a protective mechanism against decoherence. So far, however, quantum freezing has been shown to exist only on a case-by-case basis and under certain conditions, and its potential protective effect has not been fully exploited.

A Golden Gate Eclipse

more »
Shadows play on the water and in the sky in this panoramic view of the April 4 total lunar eclipse over San Francisco's Golden Gate Bridge. Just within planet Earth's shadow the Full Moon's disk is still easy to spot at its brief total phase. The urban night skyscape was composed to cover the wide range of brightness visible to the eye. The shortest total lunar eclipse of the century, this eclipse was also the third in a string of four consecutive total lunar eclipses, a series known as a tetrad. Coming in nearly six month intervals, the previous two were last April 15 and October 8. The next and final eclipse in the tetrad will be on September 28. This 2014-2015 tetrad is one of 8 total lunar eclipse tetrads in the 21st century.
