K.C. Cole will be honored at the annual ACA meeting with the Elizabeth Wood Award for her contributions to science journalism. The award recognizes individuals who have effectively communicated complex scientific concepts to the general public.
Chandra has revealed unprecedented images of a blast wave from an exploding star, a flare from a brown dwarf, and a small galaxy being cannibalized by a larger one. The observatory's high resolution has enabled scientists to pinpoint sources of the X-ray background glow, leading to a better understanding of our universe.
An Australian-led team has captured the first picture of the sky in which the Milky Way no longer blocks our view of the Universe beyond. The new survey, HIPASS, used CSIRO's Parkes radio telescope to detect large numbers of small and faint galaxies, as well as giant clouds of gas that give off no light.
A new study suggests that most gamma radiation reaching Earth is leftover energy from massive shock waves caused by gravitational forces. The collision of electrons with low-energy photons could be a sign of ordinary matter captured within intergalactic clouds, shedding light on the 'missing matter' puzzle.
Astronomers pinpointed a gamma-ray burst's precise location using coordinated observations from NASA satellites, providing data on X-rays and visible energy. The blast occurred over 10 billion light years away, roughly 2 billion years after the Big Bang.
Researchers at CU-Boulder are part of an international team experimenting with sub-atomic particles to explain how the universe came into existence. They aim to find out why there is more matter than antimatter in the universe.
NYU chemist Robert Shapiro challenges existing assumptions about life's universality with a new theory that simple cellular life may arise from organic chemistry and self-organizing systems. He also advocates for continued search for extraterrestrial life in nearby worlds like Mars, Europa, and Titan.
The FUSE Satellite will observe wavelengths of light inaccessible to other telescopes, testing models of chemical evolution and determining the primordial abundance of deuterium. This will help scientists understand the origins of the universe, galaxy evolution, and chemical mixing and distribution.
Theorists contemplate the impact of modern cosmology on Western society, noting a lack of social consensus and rootlessness. Joel Primack presents a new symbol, the cosmic uroboros, to embody an image of the cosmos consistent with modern science.
Astronomers will discuss Hubble Space Telescope findings on life in the universe, including environments suitable for life being probably plentiful. They'll also explore Mars and Jupiter's moon Europa, as well as two upcoming NASA missions searching for signs of life elsewhere in the solar system.
Astronomers have found far more dwarf galaxies than expected in a survey of just 2% of data from the Parkes radio telescope. The discovery suggests that dwarfs may be 'crumbs' left over when bigger galaxies formed and could provide clues about the distribution of dark matter.
Astronomers have detected a flash of light from a distant galaxy, potentially solving a 30-year mystery in astrophysics. The discovery suggests gamma-ray bursts originate from the distant reaches of the universe.
A paper by Peter D. Usher presents evidence that Shakespeare's Hamlet is an allegory for the competition between cosmological models of Thomas Digges and Tycho Brahe. The play dramatizes the struggle to discover the real picture of the universe from appearances in the sky. Hamlet favors the Diggesian model, which is the forerunner of m...
Astronomers analyze over 1,700 gamma-ray bursts and find they are isotropic, meaning their distribution on the sky is almost perfectly random. This contradicts previous theories that placed these bursts within or just outside of our own Milky Way Galaxy.
The Hobby-Eberly Telescope has taken its first look at the universe, demonstrating its novel design and paving the way for groundbreaking astronomical discoveries. The telescope's innovative design eliminates expensive features while tracking objects with precision, allowing for efficient and cost-effective large-scale observations.
Astronomers at Johns Hopkins University have developed a new method called photometric-redshift astronomy, which allows for rapid distance measurements to distant galaxies. This technique resolves a long-standing dilemma in cosmology research by enabling the study of galaxy evolution and dark matter.
