Hubble eXtreme Deep Field Cover For The iPad Mini

tagged with: hubble extreme deep field, hubble deep field, extreme deep field, hubble, astronomy, cosmology, galaxies, deep space, xdf, outer space

The Hubble eXtreme Deep Field (XDF) is an image of a small part of space in the center of the Hubble Ultra Deep Field within the constellation Fornax, showing the deepest optical view in space. Released on September 25, 2012, it took 10 years to compile the images and shows galaxies from 13.2 billion years ago. The exposure time was two million seconds, or approximately 23 days. The faintest galaxies are one ten-billionth the brightness of what the human eye can see. The red galaxies are the remnants of galaxies after major collisions during their elderly years. Many of the smaller galaxies are very young galaxies that eventually became the major galaxies, like the Milky Way and other galaxies in our galactic neighborhood. The Hubble eXtreme Deep Field, or XDF, adds another 5,500 galaxies to Hubble's 2003 and 2004 view into a tiny patch of the farthest universe.

This work has been released into the public domain by its author, Credit: NASA; ESA; G. Illingworth, D. Magee, and P. Oesch, University of California, Santa Cruz; R. Bouwens, Leiden University; and the HUDF09 Team.

How to estimate the magnetic field of an exoplanet

more »

Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they managed to estimate the value of the magnetic moment of the planet HD 209458b.

Riddle of the missing stars: Hubble observations cast further doubt on how globular clusters formed

more »

Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling. New observations of globular clusters in a small galaxy show they are very similar to those found in the Milky Way, and so must have formed in a similar way.

Unravelling the mystery of gamma-ray bursts with kilometer-scale microphones

more »

A team of scientists hopes to trace the origins of gamma-ray bursts with the aid of giant space ‘microphones’. It's hoped the kilometer-scale microphones will detect gravitational waves created by black holes, and shed light on the origins of the Universe.

Astronomers have discovered an unusual source of light in a galaxy some 90 million light-years away. The dwarf galaxy Markarian 177 (center) and its unusual source SDSS1133 (blue) lie 90 million light-years away. The galaxies are located in the bowl of the Big Dipper, a well-known star pattern in the constellation Ursa Major.

Researchers create 3-D stereoscopic color prints with nanopixels

more »

(Phys.org) —By designing nanopixels that encode two sets of information—or colors of light—within the same pixel, researchers have developed a new method for making 3D color prints. Each pixel can exhibit one of two colors depending on the polarization of the light used to illuminate it. So by viewing the pixels under light of both polarizations, two separate images can be seen. If the two images are chosen to be slightly displaced views of the same scene, viewing both simultaneously results in depth perception and the impression of a 3D stereoscopic image.

Study suggests black hole jets get their power from spin

more »

(Phys.org) —A team of space scientists working in Italy has found more evidence that suggests the energy needed to emit jets from supermassive black holes comes from the spin of the black hole itself. In their paper published in the journal Nature, the team describes how their survey of data from NASA's Fermi Gamma-ray Space Telescope allowed for comparing two types of emissions from the black holes, which showed a correlation.

When Isabella Lugoski Karle makes her weekly errand run to Shoppers Food Warehouse, she navigates the store quietly, weaving her cart through aisles of canned goods and around the produce section. At ninety-one, her cropped white hair is neatly combed and she holds herself up straight, loading the ingredients for a braised chicken recipe into her cart.

What Isabella Karle's fellow shoppers don't know as they wait beside her in the checkout line is that she revolutionized the method of discovering the medicines that many of them regularly purchase over at the pharmacy counter. In the narrowly...

Looking for a different sort of dark matter with GPS satellites

Science Focus

original post »

The streaked lines, forming a circular path, are the result of strong gravitational lensing caused by dark matter. Taken by the Hubble Space Telescope.

NASA, N. Benitez (JHU), T. Broadhurst (Racah Institute of Physics/The Hebrew University), H. Ford (JHU), M. Clampin (STScI), G. Hartig (STScI), G. Illingworth (UCO/Lick Observatory), the ACS Science Team and ESA

We still don’t know what dark matter is. The most widely accepted possibility is Weakly Interacting Massive Particles, or WIMPs, and most dark matter searches are looking for those. But other possibilities remain, and these alternatives to WIMPs, the "monstrous creatures at the edges of the dark matter map," are still generally particles, theoretical, exotic, or otherwise. These particles could comprise the mysterious matter that holds the galaxies together and makes up 26.8 percent of the mass-energy of the Universe.

Yet there’s another possibility, a different sort of monstrous creature, one that doesn't involve particles. Some physicists have been exploring the idea that dark matter might be ‘topological defects’ in a quantum field. Rather than solid particles, these would be perturbations, or oscillations.

This week, two physicists proposed a way to look for such defects using only atomic clocks. Atomic clocks are “arguably the most accurate scientific instruments ever built,” the researchers write in their paper. And, crucially, the clocks necessary already exist in the form of our GPS system.

Trifid Nebula, Messier 16 Sticker

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

Trifid Nebula, Messier 16 Sticker

Galaxies, Stars and Nebulae series A fantastic picture from our universe featuring the massive star factory known as the Trifid Nebula.

It was captured in all its glory with the Wide-Field Imager camera attached to the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in northern Chile.
So named for the dark dust bands that trisect its glowing heart, the Trifid Nebula is a rare combination of three nebulae types that reveal the fury of freshly formed stars and point to more star birth in the future. The field of view of the image is approximately 13 x 17 arcminutes.
It's an awe-inspiring, breathtaking image that reveals some of the wonder that is our universe.

LDN 988: Dark Nebula in Cygnus

more »
Obscuring the rich starfields of northern Cygnus, dark nebula LDN 988 lies near the center of this cosmic skyscape. Composed with telescope and camera, the scene is some 2 degrees across. That corresponds to 70 light-years at the estimated 2,000 light-year distance of LDN 988. Stars are forming within LDN 988, part of a larger complex of dusty molecular clouds along the plane of our Milky Way galaxy sometimes called the Northern Coalsack. In fact, nebulosities associated with young stars abound in the region, including variable star V1331 Cygni shown in the inset. At the tip of a long dusty filament and partly surrounded by a curved reflection nebula, V1331 is thought to be a T-Tauri star, a sun-like star still in the early stages of formation.

Galaxies, Stars and Nebulae series

A fantastic set of stickers, with a monogram for you to change, featuring a colour composite image of RCW120.

It reveals how an expanding bubble of ionised gas about ten light-years across is causing the surrounding material to collapse into dense clumps where new stars are then formed.

The 870-micron submillimetre-wavelength data were taken with the LABOCA camera on the 12-m Atacama Pathfinder Experiment (APEX) telescope. Here, the submillimetre emission is shown as the blue clouds surrounding the reddish glow of the ionised gas (shown with data from the SuperCosmos H-alpha survey). The image also contains data from the Second Generation Digitized Sky Survey (I-band shown in blue, R-band shown in red).
