Starburst galaxy sheds light on longstanding cosmic mystery
An international collaboration that includes scientists from the University of Delaware's Bartol Research Institute in the Department of Physics and Astronomy has discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth. view more (2009-11-03)
Sea level stargazing: Astronomers make key sighting with Fla. telescope
This summer, University of Florida astronomers inaugurated the world's largest optical telescope on a nearly 8,000-foot mountaintop 3,480 miles away. view more (2009-09-29)
Precise Radio-Telescope Measurements Advance Frontier Gravitational Physics
Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a major contribution to a frontier area of basic physics. view more (2009-09-02)
Sharpest views of Betelgeuse reveal how supergiant stars lose mass
Using different state-of-the-art techniques on ESO's Very Large Telescope, two independent teams of astronomers have obtained the sharpest ever views of the supergiant star Betelgeuse. view more (2009-07-29)
Galaxy Zoo hunters help astronomers discover rare 'Green Pea' galaxies
A team of astronomers has discovered a group of rare galaxies called the "Green Peas" with the help of citizen scientists working through an online project called Galaxy Zoo. The finding could lend unique insights into how galaxies form stars in the early universe. view more (2009-07-28)
Caltech visiting associate champions the study of solar eclipses in the modern era
Championing the modern-day use of solar eclipses to solve a set of modern problems is the goal of a review article written by Jay Pasachoff, visiting associate at the California Institute of Technology (Caltech) and Field Memorial Professor of Astronomy at Williams College. view more (2009-06-11)
Radio telescopes extend astronomy's best 'yardstick'
Radio astronomers have directly measured the distance to a faraway galaxy, providing a valuable "yardstick" for calibrating large astronomical distances and demonstrating a vital method that could help determine the elusive nature of the mysterious Dark Energy that pervades the Universe. view more (2009-06-09)
Rare radio supernova in nearby galaxy is nearest supernova in five years
The chance discovery last month of a rare radio supernova - an exploding star seen only at radio wavelengths and undetected by optical or X-ray telescopes - underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust. view more (2009-05-28)
Windy, wet and wild: Victoria Crater unveils more of Mars' geologic past
After thoroughly investigating Victoria Crater on Mars for two years, the instruments aboard the Rover Opportunity reveal more evidence of our neighboring red planet's windy, wet and wild past. view more (2009-05-22)
Lightest exoplanet yet discovered
Well-known exoplanet researcher Michel Mayor today announced the discovery of the lightest exoplanet found so far. The planet, "e", in the famous system Gliese 581, is only about twice the mass of our Earth. view more (2009-04-22)
Scientists pinpoint the 'edge of space'
Where does space begin? Scientists at the University of Calgary have created a new instrument that is able to track the transition between the relatively gentle winds of Earth's atmosphere and the more violent flows of charged particles in space - flows that can reach speeds well over 1000 km/hr. And they have accomplished this in unprecedented... view more... (2009-04-10)
UBC, U of T team helps solve mystery of starlight's origins
Scientists from the University of Toronto and the University of British Columbia have helped unveil the birthplaces of ancient stars using a two-tonne telescope carried by a balloon the size of a 33-storey building. view more (2009-04-09)
Astronomy's bright future
To mark UNESCO's International Year of Astronomy (IYA2009), six leading astronomers from the UK, the US, Europe and Asia write in March's Physics World about the biggest challenges and opportunities facing international astronomers over the next couple of decades. view more (2009-03-02)
Clemson scientists launch rockets to test atmospheric conditions
Clemson University space physicists have traveled around the world to launch rockets to test atmospheric conditions. view more (2009-02-27)
Space engineers from India work with University of Leicester for first national astronomy satellite
India's first national Astronomy satellite- Astrosat- is to have key components assembled by the University of Leicester. view more (2009-02-04)
Looking through Galileo's eyes
In 1609, exactly four centuries ago, Galileo revolutionised humankind's understanding of our position in the Universe when he used a telescope for the first time to study the heavens, which saw him sketching radical new views of the moon and discovering the satellites orbiting Jupiter. view more (2009-01-08)
Black Holes Lead Galaxy Growth, New Research Shows
Astronomers may have solved a cosmic chicken-and-egg problem -- the question of which formed first in the early Universe -- galaxies or the supermassive black holes seen at their cores. view more (2009-01-07)
Cassiopeia A comes alive across time and space
Two new efforts have taken a famous supernova remnant from the static to the dynamic. A new movie of data from NASA's Chandra X-ray Observatory shows changes in time never seen before in this type of object. A separate team will also release a dramatic three-dimensional visualization of the same remnant. view more (2009-01-06)
Predicted Planet Seen-First Since Neptune 162 Years Ago
In 2006, astronomer Alice Quillen of the University of Rochester predicted that a planet of a particular size and orbit must lie within the dust of a nearby star. That planet has now been photographed by the Hubble Space Telescope, making it only the second planet ever imaged after an accurate prediction. view more (2008-12-10)
New Hybrid Nanostructures Detect Nanoscale Magnetism
A key challenge of nanotechnology research is investigating how different materials behave at lengths of merely one-billionth of a meter. When shrunk to such tiny sizes, many everyday materials exhibit interesting and potentially beneficial new properties. view more (2008-12-09)
