Rapid star formation spotted in 'stellar nurseries' of infant galaxies
The findings show that "stellar nurseries" within the first galaxies gave birth to stars at a much more rapid rate than previously expected, the researchers from Durham's Institute for ...

Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the ...

On 3 September, Herschel aimed its telescope at a reservoir of cold gas in the constellation of the Southern Cross near the Galactic Plane. As the telescope scanned the sky, the spacecraft’s Spectral ...
Physics and Astronomy | Read moreStar-birth myth 'busted'
When a cloud of interstellar gas collapses to form stars, the stars range from massive to minute.Since the 1950s astronomers have thought that in a family of new-born stars the ratio of massiv...
Physics and Astronomy | Read moreTrigger-happy star formation
While astronomers have long understood that stars and planets form from the collapse of a cloud of gas, the question of the main causes of this process has remained open.One option is that the...

New images taken with two of Spitzer's infrared detector channels -- the two that work at the new warmer temperature -- demonstrate that the observatory remains a powerful tool for probing the du...

The Galaxy Zoo users, who volunteer their spare time to help classify galaxies in an online image bank, came across a number of objects that stuck out because of their small size and bright green colo...

Sporting a 3.5-meter mirror, the Herschel Space Observatory is the largest space telescope ever built and flown. Herschel is about one-and-one-half times the diameter of the Hubble Space Telescope....

In this composite made of X-rays from Chandra shown in purple and infrared data from Spitzer shown in green and red, SNR 0104 looks unlike other likely Type Ia remnants found in our own Galaxy. While ...
Physics and Astronomy | Read moreIU astronomer’s discovery poses challenge to galaxy formation theories
This would run counter to the widely-held belief that massive, luminous galaxies (like our own Milky Way Galaxy) began their formation and evolution shortly after the Big Bang, some 13 billion years a...

Physics and Astronomy | Read moreInfant galaxies - small and hyperactive
When galaxies are born, do their stars form everywhere at once, or only within a small core region? Recent measurements of an international team led by scientists from the Max Planck Institute for Ast...
Physics and Astronomy | Read moreNew understanding of the origin of galaxies advanced
A new theory as to how galaxies were formed in the Universe billions of years ago has been formulated by Hebrew University of Jerusalem cosmologists. The theory takes issue with the prevailing view on...
