Newly-Released Hypatia Catalog Offers Glimpse Into The Lives Of Stars

April Flowers for redOrbit.com - Your Universe Online The largest catalog ever assembled for stellar compositions was unveiled this week by Arizona State University (ASU) alumna Natalie Hinkle. Hinkle, who graduated in 2012 from ASU with a...

April Flowers for redOrbit.com - Your Universe Online The Hubble Space Telescope is a joint project between NASA and the European Space Agency (ESA) that launched in 1990. Since then, it has returned thousands of images from its orbital position above the atmosphere, helping scientists to shed light on some of the mysteries of the cosmos. Hubble images prove that there is more to a galaxy than what first meets the eye. The telescope is able to look beyond the bright glow of a galaxy's...

Astronomers Use AKARI Orbiting Observatory To Map Space’s Icy Wastes
2014-06-26 03:40:16

Royal Astronomical Society Using the AKARI orbiting observatory, astronomers from the Open University have made the first large-scale maps of icy material where stars are forming. In a challenge to conventional ideas about the formation of water in space, they find ice in regions with little dust or gas. Dr Helen Fraser, who led the new work, presented the results in her talk at the National Astronomy Meeting in Portsmouth this week. Launched by the Japanese space agency JAXA in 2006,...

Organic Conundrum In Milky Way’s Satellite Galaxy, The Large Magellanic Cloud
2014-06-23 03:03:26

Royal Astronomical Society A group of organic chemicals that are considered carcinogens and pollutants today on Earth, but are also thought to be the building blocks for the origins of life, may hold clues to how carbon-rich chemicals created in stars are processed and recycled in space. Scientists have studied how polycyclic aromatic hydrocarbons (PAHs) are created in an aging population of stars in the Milky Way’s satellite galaxy, the Large Magellanic Cloud. They have found that...

3D Map Details Dusty Structure Of The Milky Way
2014-06-23 03:19:28

Royal Astronomical Society A team of international astronomers has created a detailed three-dimensional map of the dusty structure of the Milky Way – the star-studded bright disc of our own galaxy – as seen from Earth’s northern hemisphere. The map will be presented by Prof Janet Drew of the University of Hertfordshire at the National Astronomy Meeting (NAM) 2014 in Portsmouth on Monday 23 June. Dust and gas, making up the Interstellar Medium (ISM), fill space between stars in...

Star Measurement Made Easier With A Novel Spectral Ruler
2014-06-23 14:32:00

Brett Smith for redOrbit.com - Your Universe Online Being hailed as a critical first step in a massive attempt to map the Milky Way, a team of European astronomers has devised a novel way to categorize stars based on their metallic composition, according to a new paper published in the journal Astronomy & Astrophysics. The study team developed their ‘spectral ruler’ by selecting 34 'benchmark' stars to characterize the distinct kinds of stellar groups in our galaxy, such as hot...

Smith Cloud Survives Galactic Collision Thanks To Full Dark-matter Facket
2014-05-23 03:44:33

National Radio Astronomy Observatory Like a bullet wrapped in a full metal jacket, a high-velocity hydrogen cloud hurtling toward the Milky Way appears to be encased in a shell of dark matter, according to a new analysis of data from the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT). Astronomers believe that without this protective shell, the high-velocity cloud (HVC) known as the Smith Cloud would have disintegrated long ago when it first collided with the disk...

Cosmic Clumps Cast Darkest Shadows Ever Recorded
2014-05-22 03:51:02

Whitney Clavin, NASA's Jet Propulsion Laboratory Astronomers have found cosmic clumps so dark, dense and dusty that they throw the deepest shadows ever recorded. Infrared observations from NASA's Spitzer Space Telescope of these blackest-of-black regions paradoxically light the way to understanding how the brightest stars form. The clumps represent the darkest portions of a huge, cosmic cloud of gas and dust located about 16,000 light-years away. A new study takes advantage of the...

A Star Cluster In The Wake Of Carina
2014-05-21 03:14:10

[ Watch The Video: Panning Across The Colorful Star Cluster NGC 3590 ] ESO NGC 3590 is a small open cluster of stars around 7500 light-years from Earth, in the constellation of Carina (The Keel). It is a gathering of dozens of stars loosely bound together by gravity and is roughly 35 million years old. This cluster is not just pretty; it is very useful to astronomers. By studying this particular cluster — and others nearby — astronomers can explore the properties of the spiral...

redOrbit Staff & Wire Reports - Your Universe Online A team of astronomers have identified what is believed to be the sibling of our sun – a star thought to have been born from the same cloud of gas as the one that provides our solar system with light and warmth. According to Deborah Netburn of the Los Angeles Times, the sun’s so-called long-lost brother is slightly bigger and has a somewhat hotter surface temperature than the star around which the Earth orbits. However, an...

Magnetic Fingerprint Of Our Galaxy Revealed By Planck
2014-05-06 03:21:32

ESA Our Galaxy's magnetic field is revealed in a new image from ESA's Planck satellite. This image was compiled from the first all-sky observations of 'polarized' light emitted by interstellar dust in the Milky Way. Light is a very familiar form of energy and yet some of its properties are all but hidden to everyday human experience. One of these – polarization – carries a wealth of information about what happened along a light ray's path, and can be exploited by astronomers....

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...
