Researchers discovered pulsar bursts coming from beachball-sized structures in the Crab Nebula, a cloud of debris from a supernova. The structure's small size is inconsistent with all but one proposed theory for generating radio emission.
The NSF has awarded a design grant for the Square Kilometer Array (SKA) telescope, which aims to be the largest scientific instrument ever built. The U.S. consortium, led by Cornell University, will investigate feed antennas and low-temperature receivers, as well as address radio frequency interference issues.
The NASA Living With a Star program aims to understand the dynamics of the Earth-Sun system. The Stanford-led SDO mission will study the Sun's magnetic fields, creating 3D images of solar magnetic regions and surface fields, to predict destructive flares and solar storms.
The Space Infrared Telescope Facility (SIRTF) will study blue compact dwarf galaxies, which are deficient in heavy elements and contain as little as 2 percent of the solar system's share. The telescope will provide detailed physical information about distant targets using its infrared spectrograph instrument.
The DEIMOS instrument will multiply the power of current Keck spectroscopy by a factor of seven, enabling observations of distant galaxies and shedding light on the formation and evolution of galaxies. With its massive detector and advanced optics, DEIMOS will create the most comprehensive map of the distant universe ever attempted.
Astronomers estimate masses of distant black holes using a new method developed by Marianne Vestergaard, allowing for more accurate understanding of quasar behavior. The study challenges previous theories suggesting a threshold mass above which black holes cause quasars to become radio-loud.
Astronomers have detected X-ray radiation from the Milky Way’s center for over two decades, but the origin remained a mystery due to poor resolution. The new image reveals individual X-ray sources and hot gas, leading scientists to conclude that most high-energy radiation comes from white dwarf stars, neutron stars, and black holes.
A team of astronomers led by UMass' Daniel H. McIntosh found evidence of galaxies transforming in response to their environment. They observed three massive galaxy clusters and discovered a link between a galaxy's surroundings and its evolution, with blue galaxies forming stars while reddish galaxies have few stars.
The National Virtual Observatory will unite various astronomical databases, taking advantage of computer technology and data storage techniques. This project aims to maximize scientific insights from data, making them accessible to professional researchers, amateur astronomers, and students.
The National Virtual Observatory will unite diverse astronomical databases, making it easier for researchers to access and analyze data. The project aims to streamline data analysis techniques and promote collaboration among institutions.
Researchers at the University of Illinois and Wisconsin detected a Y-shaped ionized gas filament near the Big Dipper, believed to be produced by radiation from a white dwarf or low-luminosity source. The object's properties differ from other examples, making it difficult to identify its origin.
A team of U.S. and European astronomers detect X-rays from the farthest known quasar, SDSSp J1044-0125, with a redshift of 5.8, revealing the universe's earliest objects. The quasar's low X-ray emission suggests it may be a 'precursor quasar' or have strong accretion processes.
Scientists have found a mid-mass black hole in the M82 galaxy, which packs the mass of at least 500 suns into a region about the size of the Moon. The discovery opens a new field of research and suggests that such black holes may exist in our own galaxy.
The Chandra X-ray Observatory has been selected as one of the top 100 'Best of What's New' items by Popular Science magazine, highlighting its significant contributions to X-ray astronomy. The observatory is already sending back impressive images that are aiding in understanding exploding stars, black holes, and other celestial phenomena.
The High Energy Transmission Grating Spectrometer has made the most precise measurements ever recorded of a star's corona, revealing new insights into stellar behavior. The instrument's success marks a major milestone for modern astronomy, enabling scientists to study the chemical composition and temperature of the corona with unpreced...
The Large Angle and Spectrometric COronagraph Experiment (LASCO) on the SOHO spacecraft has made public images and movies taken during the week of December 22-27, 1996. The released data includes coronagraphic images and a movie with an image cadence of approximately 50 minutes.
A delegation from the Hobby-Eberly Telescope Project is meeting with South African astronomers to discuss collaboration on constructing a large astronomical telescope. The proposed telescope would be similar in design to the existing Hobby-Eberly Telescope, featuring an 11m primary mirror and 91 hexagonal segments.
