A team of European astronomers has used ESO’s Very Large Telescope and a host of other telescopes to discover and study the most distant quasar found to date. This brilliant beacon, powered by a black hole with a mass two billion times that of the Sun, is by far the brightest object yet discovered in the early Universe. The results will appear in the 30 June 2011 issue of the journal Nature.
Using the VISIR instrument on ESO’s Very Large Telescope (VLT), astronomers have imaged a complex and bright nebula around the supergiant star Betelgeuse in greater detail than ever before. This structure, which resembles flames emanating from the star, is formed as the behemoth sheds its material into space.
The Five-hundred-meter Aperture Spherical radio Telescope (FAST), under construction in Guizhou Province in southern China, will be able to see more than
Centaurus A, also known as NGC 5128, is well known for its dramatic dusty lanes of dark material. Hubble's observations, using its most advanced instrument, the Wide Field Camera 3, are the most detailed ever made of this galaxy. They have been combined here in a multi-wavelength image that reveals never-before-seen detail in the dusty portion of the galaxy.
The Defense Department first proposed Star Wars. Now it wants Star Trek.
By shooting a beam of neutrinos through a small slice of the Earth under Japan, physicists say they
Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA
After 30 years of development, the UK and European space agencies have given a go for the Skylon Spaceplane.
A recent study says that a particular mathematical technique could be used to detect forests on extrasolar planets.
(PhysOrg.com) -- University of Notre Dame astronomer David Bennett is co-author of a new paper describing the discovery of a new class of planets -- dark, isolated Jupiter-mass bodies floating alone in space, far from any host star. Bennett and the team of astronomers involved in the discovery believe that the planets were most likely ejected from developing planetary systems.
(PhysOrg.com) -- In a new study, scientists have proposed that mini black holes may interact with matter very differently than previously thought. If the proposal is correct, it would mean that the time it would take for a mini black hole to swallow the Earth would be many orders of magnitude longer than the age of the Universe.
A team of scientists has discovered a new mineral -- krotite, one of the earliest minerals formed in our solar system. It is the main component of an unusual inclusion embedded in a meteorite (NWA 1934), found in northwest Africa. These objects, known as refractory inclusions, are thought to be the first planetary materials formed in our solar system, dating back to before the formation of Earth and the other planets.
The Meathook Galaxy, or NGC 2442, has a dramatically lopsided shape. One spiral arm is tightly folded in on itself and host to a recent supernova, while the other, dotted with recent star formation, extends far out from the nucleus. The NASA/ESA Hubble Space Telescope and the MPG/ESO 2.2-meter telescope have captured two contrasting views of this asymmetric spiral galaxy.
