During the Summer school holidays discover and create other worlds through a great program of activities just for kids.

Black holes sprout galaxies, not vice versa

A view of the neighboring Andromeda galaxy. Researchers weighed the black hole at the center of a given galaxy as compared to the galaxy's "bulge," stars and gas located relatively close to its center. Younger galaxies had different weight ratios than older ones.

Water Detected At Record Distance From Earth

Matt_dk writes with news that scientists have detected water in a galaxy 11.5 billion light-years from Earth. Evidence came in the form of emissions from water masers around a quasar at the center of the galaxy. Detection at such a large distance was made possible by a closer, intervening galaxy which acted as a gravitational lens. "'We were only able to discover this distant water with the help of the gravitational lens,' said Violette Impellizzeri, an astronomer with the Max-Planck Institute for Radioastronomy (MPIfR) in Bonn, Germany. 'This cosmic telescope reduced the amount of time needed to detect the water by a factor of about 1,000,' she added. The astronomers first detected the water signal with the Effelsberg telescope. They then turned to the VLA's sharper imaging capability to confirm that it was indeed coming from the distant

Water in the Early Universe

The discovery of water in the early Universe was possible only due to the chance alignment of a foreground galaxy and the distant quasar MG J0414+0534. The foreground galaxy acts like a cosmic telescope, magnifying and distorting the light from the quasar forming four distinct images of the quasar. Without this gravitational lensing effect, 580 days of continuous observations with the 100 m telescope would have been needed instead of the 14 hours used to make this remarkable discovery. "Others have tried and failed to find water, and we knew we were looking for a very faint signal", says Violette Impellizzeri, "so we thought of using a foreground galaxy like a cosmic magnifying glass to observe at a far greater distance and had to be persistent, and sure enough the line emission of water popped up.

Astronomers Use Gamma-ray Burst To Probe Star Formation In The Early Universe

The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy. By analyzing the spectrum of light emitted in the GRB afterglow, the researchers are gleaning insights into an active stellar nursery in a galaxy so far away it appears as it was 10 billion years ago.

Astronomers Dissect a Supermassive Black Hole

Matt_dk sends along a piece from the European Southern Observatory, which reports on observations of the so-called "Einstein Cross," a fortuitous conjunction of a nearby galaxy and a distant black hole. A team of researchers from Europe and the US combined the effects of macrolensing (from the intervening galaxy) and microlensing (from stars in that galaxy), captured by an earth-bound telescope. "Combining a double natural 'magnifying glass' with the power of ESO's Very Large Telescope, astronomers have scrutinized the inner parts of the disc around a supermassive black hole 10 billion light-years away. They were able to study the disc with a level of detail a thousand times better than that of the best telescopes in the world, providing the first observational confirmation of the prevalent theoretical models of such discs.

Astrophysicist Helps Map the Milky Way's Four Spiral Arms

Martin Pohl, an Iowa State University associate professor of physics and astronomy, is part of a research team that developed the first complete map of the Milky Way galaxy's spiral arms. The map shows two prominent, symmetric spiral arms in the inner part of the galaxy. The arms extend into the outer galaxy where they branch into four spiral arms.

Galaxy Clusters' Stunted Growth Confirms Dark Energy

A new study of 86 galaxy clusters in the early universe has provided independent confirmation of the existence of dark energy. In its absence, gravity's pull should have caused the number of clusters to increase by a factor of 50 over the last 5.5 billion years. What is observed is a factor of 10 increase. "Together with earlier observations... the new data strengthen the suspicion — but do not prove — that dark energy is a weird antigravity called the cosmological constant that was hypothesized and then abandoned by Albert Einstein as a 'blunder' almost a century ago. If that is true, the universe is fated to empty itself out eventually, and all but the Milky Way's closest neighbors will eventually be out of sight. ... Adam Riess of Johns Hopkins and the Space Telescope Science Institute, said: 'If this was a fox hunt and dark energy

Massive galaxy mergers sparked bursts of star formation when Universe was 6 bln yrs old

A survey, using data obtained from the Hubble Space Telescope, has determined that nearly all massive galaxies have undergone at least one major merger since the Universe was 6 billion years old, resulting in bursts of star formation. hubble-space-telescope-300x225 Massive galaxy mergers sparked bursts of star formation when Universe was 6 bln yrs old

Yo Galaxy's Mama Is a Black Hole

Lurking deep inside the center of almost all galaxies is a ravenous, super-massive black hole, and new research suggests the black hole may have given birth to its galaxy. This could be the answer to a long-standing astronomical chicken-and-egg problem.

Quasar scrutineers use entire galaxy as telescope lens

A team of crafty astroboffins say they have managed to probe the guts of a quasar ten billion lightyears away - using nothing less than an entire galaxy as the main lens of their telescope.

Core of the galaxy in high-res

This false-color panorama of the central 300 light-years of the Milky Way shows the glow from ionized hydrogen gas and a multitude of young stars. The infrared portrait is the sharpest ever taken of our galaxy core. The mosaic combines images taken by the Hubble Space Telescope’s Near Infrared Camera and Multi-Object Spectrometer with lower-resolution images from NASA’s Spitzer Space Telescope. Orange indicates emissions at an infrared wavelength of 5.8 micrometers and red is 8 micrometers.Â
