Anatomy of a cosmic seagull

Colourful and wispy, this intriguing collection of objects is known as the Seagull Nebula, named for its resemblance to a gull in flight. Made up of dust, hydrogen, helium and traces of heavier elements, this region is the ...

Production sites of stars are rare

Astronomers using the Nobeyama Radio Obeservatory (NRO) 45-meter telescope found that high-density gas, the material for stars, accounts for only 3 percent of the total mass of gas distributed in the Milky Way. This result ...

Star formation may be halted by cold ionized hydrogen

For the first time ionized hydrogen has been detected at the lowest frequency ever towards the center of our Galaxy. The findings originate from a cloud that is both very cold (around -230 degrees Celsius) and also ionized, ...

Technique pulls interstellar magnetic fields within easy reach

A new, more accessible and much cheaper approach to surveying the topology and strength of interstellar magnetic fields—which weave through space in our galaxy and beyond, representing one of the most potent forces in nature—has ...

Spitzer captures stellar family portrait

In this large celestial mosaic taken by NASA's Spitzer Space Telescope, there's a lot to see, including multiple clusters of stars born from the same dense clumps of gas and dust. Some of these clusters are older than others ...

Galaxies as 'cosmic cauldrons'

Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly inefficiently. Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic ...

Neotropical cloud forests to lose what most defines them: clouds

In as few as 25 years, climate change could shrink and dry 60-80% of Western Hemisphere cloud forests, finds a study published today. If greenhouse gas emissions continue increasing as they have been, 90% of Western Hemisphere ...

Star formation in galactic centers

Stars form from the gas and dust in molecular clouds via a series of complex processes that are currently only partly understood, and the evolution of these clouds drives the evolution of the stellar populations in the universe. ...
