IC 342
(Preview)
IC 342 is an intermediate spiral galaxy in the constellation Camelopardalis. The galaxy is located near the galactic equator where dust obscuration makes it a difficult object for both amateur and professional astronomers to observe. [url=http://en.wikipedia.org/wiki/IC_342]Read more[/...

NGC 1132
(Preview)
The elliptical galaxy NGC 1132 reveals the final result of what may have been a group of galaxies that merged together in the recent past. Another possibility is that the galaxy formed in isolation as a "lone wolf" in a universe ablaze with galaxy groups and clusters. This image of NGC 1132...

Perseus Galaxy Cluster
(Preview)
Suzaku Shows Clearest Picture Yet Of Perseus Galaxy Cluster X-ray observations made by the Suzaku observatory provide the clearest picture to date of the size, mass and chemical content of a nearby cluster of galaxies. The study also provides the first direct evidence that million-degree gas cl...

GW170104
(Preview)
GW170104 was a gravitational wave signal detected by the LIGO observatory on 4 January 2017. On 1 June 2017, the LIGO and Virgo collaborations announced that they had reliably verified the signal, making it the third such signal, after GW150914 and GW151226. Read more

Ingredients for life
(

)
(Preview)
NASA's Spitzer Space Telescope has found the ingredients for life all the way back to a time when the universe was a mere youngster.
Using Spitzer, scientists have detected organic molecules in galaxies when our universe was one-fourth of its current age of about 14 billion years. These large mol...

ULIRGs
(Preview)
The Spitzer Space Telescope has observed a rare population of colliding galaxies whose entangled hearts are wrapped in tiny crystals resembling crushed glass.
The crystals are essentially sand, or silicate, grains that were formed like glass, probably in the stellar equivalent of furnace...

The Universe

(Preview)
The Universe is beige After studying the colour of light emitted by 200,000 galaxies scientists have combined them to produce the colour, they have dubbed 'cosmic latte'. Other names suggested for it were 'univeige' and 'skyvory'. But apparently this colour has changed over the last six billion y...

CXO J101527.2+625911
(Preview)
CXO J101527.2+625911: Astronomers Pursue Renegade Supermassive Black Hole Supermassive holes are generally stationary objects, sitting at the centers of most galaxies. However, using data from NASA's Chandra X-ray Observatory and other telescopes, astronomers recently hunted down what c...

Galaxies

A team of astronomers from Cardiff University and the University of Washington Seattle reports in the journal 'Nature' this week that they have discovered that galaxies are much simpler than anybody thought. Galaxies are enormous whirlpools of stars, and the Sun is but one star in our own Milky Way...

Primeval hydrogen gas

Ripples in Cosmic Web Measured Using Rare Double Quasars The most barren regions of the Universe are the far-flung corners of intergalactic space. In these vast expanses between the galaxies there are only a few atoms per cubic meter - a diffuse haze of hydrogen gas left over from the Big Bang. Viewed...

It is one of the major goals of observational cosmology to trace the way galaxies formed and evolved and to compare it to predictions from theoretical models. It is therefore essential to know as precisely as possible how many galaxies were present in the Universe at different epochs.
This is ea...
