Artist’s impression of the monster galaxy COSMOS-AzTEC-1. This galaxy is located 12.4 billion light-years away and is forming stars 1,000 times more rapidly than our Milky Way galaxy. ALMA observations revealed dense gas concentrations in the disk, and intense star formation in those concentrations. Credit: National Astronomical Observatory of Japan

An international team of astronomers from Japan, Mexico and the University of Massachusetts Amherst studying a “monster galaxy” 12.4 billion light years away today report that their instruments have achieved a 10 times higher angular resolution than ever before, revealing galaxy structural details previously completely unknown. They also were able to analyze dynamic properties that could not be probed before.

This spectacular image of the Carina nebula reveals the dynamic cloud of interstellar matter and thinly spread gas and dust as never before. The massive stars in the interior of this cosmic bubble emit intense radiation that causes the surrounding gas to glow. By contrast, other regions of the nebula contain dark pillars of dust cloaking newborn stars.

VISTA gazes into one of the largest nebulae in the Milky Way in infrared. About 7500 light-years away, in the constellation of Carina, lies a nebula within which stars form and perish side-by-side. Shaped by these dramatic events, the Carina Nebula is a dynamic, evolving cloud of thinly spread interstellar gas and dust.

Scientists challenges idea that life requires ‘Earth clone’. The conditions for life surviving on planets entirely covered in water are more fluid than previously thought, opening up the possibility that water worlds could be habitable, according to a new paper from the University of Chicago and Pennsylvania State University.

The scientific community has largely assumed that planets covered in a deep ocean would not support the cycling of minerals and gases that keeps the climate stable on Earth, and thus wouldn’t be friendly to life. But the study, published Aug...

An image from NASA Solar Dynamics Observatory (SDO) satellite that shows an example of a commonly believed Slinky-like shaped coronal mass ejection (CME) — in this case a long filament of solar material hovering in the sun’s atmosphere, or corona. This CME traveled 900 miles per second connecting with Earth’s magnetic environment and causing aurora to appear four days later on Sept. 3, 2012.

As the saying goes, everything old is new again. While the common phrase often refers to fashion, design, or technology, scientists at the University of New Hampshire have found there is some truth to this mantra even when it comes to research...
