ESA's Herschel Space Observatory has detected cosmic dust from a supernova, adding to the theory that these cosmic fireworks are responsible for its creation. The astronomers who used Herschel to make the discovery said origin of the dust is important because it plays a crucial role in the formation of stars, particularly billions of years ago when star formation was at its peak.  "Interestingly, this brand new clue does not come from observations of very distant galaxies, but from one...

On Thursday, NASA released a colorful image of the RCW 120 nebula taken bb the Spitzer space telescope. This nebula is 4,300 light-years away in the constellation Scorpius just above the plane of the galaxy. It emits a broad range of colors in the infrared region and has wavelengths beyond what humans can see. The ring-shaped cloud of gas and dust is believed to have originated from the heat of giant "O" type stars at the ring's center. These are the largest and brightest stars scientists...

Astronomers have discovered another galaxy about 30 million light years away that looks like a giant Milky Way "clone". The galaxy would be identical to the Milky Way if its diameter was not twice that of the Milky Way. "This view could almost be a picture postcard of our own Milky Way, taken and sent by an extragalactic friend, as this galaxy closely resembles our own," the European Southern Observatory (ESO) said in a statement. The galaxy lies about 30 million light years away, in the...

An extraordinarily bright isolated star has been found in a nearby galaxy "” the star is three million times brighter than the Sun. All previous similar "superstars" were found in star clusters, but this brilliant beacon shines in solitary splendor. The origin of this star is mysterious: did it form in isolation or was it ejected from a cluster? Either option challenges astronomers' understanding of star formation. An international team of astronomers [1] has used ESO's Very Large...

Stanford University astrophysicist Risa Wechsler andother researchers have found that only four percent of galaxies are similar to the Milky Way galaxy. The team compared the Milky Way to similar galaxies in terms of luminosity and distance to other bright galaxies.  They found that galaxies with two satellites that are as bright and close by as the Milk Way's two closest satellites, the Large and Small Magellanic Clouds, are hard to come by. According to a press release by the...

A study of spiral patterns found in galaxies like our Milky Way could overturn the theory of how the spiral arm features form and evolve. The results are being presented by postgraduate student, Robert Grand, at the Royal Astronomical Society's National Astronomy Meeting in Llandudno, Wales this week. Since 1960s, the most widely accepted explanation has been that the spiral arm features move like a Mexican wave in a crowd, passing through a population of stars that then return to their...

ESA's Herschel space observatory has revealed that nearby interstellar clouds contain networks of tangled gaseous filaments. Intriguingly, each filament is approximately the same width, hinting that they may result from interstellar sonic booms throughout our Galaxy. The filaments are huge, stretching for tens of light years through space and Herschel has shown that newly-born stars are often found in the densest parts of them. One filament imaged by Herschel in the Aquila region...

The region around the center of our Milky Way galaxy glows colorfully in this new version of an image taken by NASA's Spitzer Space Telescope. The data were previously released as part of a long, 120-degree view of the plane our galaxy (see this page). Now, data from the very center of that picture are being presented at a different contrast to better highlight this jam-packed region. In visible-light pictures, it is all but impossible to see the heart of our galaxy, but infrared light...

Observing the X-ray-bright gas in the halo of the Milky Way, ESA's XMM-Newton has gathered new data which favor a process involving fountains of hot gas in our Galaxy. Such a scenario, with the gas flowing from the galactic disc into the halo where it then condenses into cooler clouds and subsequently falls back to the disc, confirms the importance of supernova explosions in forging the evolution of the interstellar medium and of the entire Galaxy. The interstellar medium (ISM) in the Milky...

Astronomers have discovered bucket loads of buckyballs in space. They used NASA's Spitzer Space Telescope to find the little carbon spheres throughout our Milky Way galaxy -- in the space between stars and around three dying stars. What's more, Spitzer detected buckyballs around a fourth dying star in a nearby galaxy in staggering quantities -- the equivalent in mass to about 15 of our moons. Buckyballs, also known as fullerenes, are soccer-ball-shaped molecules consisting of 60 linked carbon...

Milky Way Galaxy -- The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia (gala, galactos means "milk")) is a hazy band of white light across the night sky formed by billions of stars in the disc of our galaxy. The Milky Way appears brightest in the direction of Sagittarius, where the galactic centre lies. Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of...
