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...

Astronomers May Have Found Coldest, Faintest White Dwarf Ever
2014-06-23 14:57:23

Brett Smith for redOrbit.com - Your Universe Online Using data from three different telescopes, a large international team of astronomers has identified what could be the coldest, faintest while dwarf ever, according to a new report in the Astrophysical Journal. The report said the temperature of the stellar vestige is so low, the carbon it contains has probably undergone crystallization, a process that results in the formation of a diamond here on Earth. “It’s a really...

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...

coronal puff
2014-06-23 11:26:58

Royal Astronomical Society (RAS) A suite of Sun-gazing spacecraft, SOHO, STEREO and Solar Dynamics Observatory (SDO), have spotted an unusual series of eruptions in which a series of fast 'puffs' force the slow ejection of a massive burst of plasma from the Sun's corona. The eruptions took place over a period of three days, starting on 17 January 2013. Images and animations of the phenomena were presented at the National Astronomy Meeting 2014 in Portsmouth by Nathalia Alzate on Monday 23...

Scientists Scratching Their Heads Over Titan's Vanishing 'Magic Island'
2014-06-23 10:52:26

Brett Smith for redOrbit.com - Your Universe Online A mysterious “island” that suddenly appeared and then disappeared on one of Saturn’s moons, as seen in NASA images, has scientists baffled. Dubbed the “Magic Island,” the feature on Titan, Saturn’s largest moon, showed up in an image captured by NASA's Cassini probe last year. Images of the same location captured nothing before or days after. According to a paper on the phenomenon published in Nature Geoscience, the...

NASA Discusses Progress Reached So Far In Future Asteroid Mission
2014-06-20 12:35:12

Brett Smith for redOrbit.com - Your Universe Online Proposed studies for NASA’s missions to capture and redirect an asteroid are set to kick off in July. The space agency said these studies should inform not only the future asteroid mission, but also future missions to Mars. "With these system concept studies, we are taking the next steps to develop capabilities needed to send humans deeper into space than ever before, and ultimately to Mars, while testing new techniques to protect...

Stream Of Gas Observed Escaping Grasp Of Supermassive Black Hole
2014-06-20 10:53:54

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The classic image of black hole systems is the in-flowing gas being consumed by the singularity. However, black holes are far from simply being cosmic vacuum cleaners, and occasionally even exhibit some strange behavior. Recently, a team of astronomers found a clumpy stream of gas quickly flowing outward from the supermassive black hole at the core of the galaxy NGC 5548. This unusual phenomenon was discovered when a...

Geometry
2014-01-02 10:21:51

Geometry is a branch of mathematics that is concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the geometry field is called a geometer. Geometry arose independently in numerous early cultures as a body of practical knowledge concerning areas, lengths, and volumes, with elements of a formal mathematical science emerging in the West as early as Thales. By the 3rd century BC, geometry was put into an axiomatic form by...

Stellar Astrophysics

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...
