The world's fourth-largest optical telescope has a new experiment coming online.
In January 2002, astronomers discovered a massive explosion coming from V838 Monocerotis. They initially thought they were witnessing a supernova, but after the initial flash of light began to dim (as expected), it began to brighten again in infrared wavelengths at the beginning of March. After that brightening faded, another one happened in April.
The pulsar at the center of the famous Crab Nebula is a veritable bundle of energy. Astronomers observed the pulsar in the area of very high energy gamma radiation from 25 up to 400 gigaelectronvolts (GeV), a region that was previously difficult to access with high energy instruments, and discovered that it actually emits pulses with the maximum energy of up to 400 GeV -- 50 to 100 times higher than theorists thought possible. These latest observations are difficult for astrophysicists to explain.
The European Southern Observatory (Eso) has linked up its four telescopes of the Very Large Telescope (VLT) at the Paranal Observatory to form a virtual
Humanity's most complex ground-based astronomy observatory, the Atacama Large Millimeter/submillimeter Array (ALMA), has officially opened for astronomers. The first released image, from a telescope still under construction, reveals a view of the Universe that cannot be seen at all by visible-light and infrared telescopes. Thousands of scientists from around the world have competed to be among the first few researchers to explore some of the darkest, coldest, furthest, and most hidden secrets of the cosmos with this new astronomical tool.
The IceCube Neutrino Observatory, built over a decade at a cost of $271 million, is buried under the South Pole... and longer than the world
Usually, running five minutes late is a bad thing since you might lose your dinner reservation or miss out on tickets to the latest show. But when a planet runs five minutes late, astronomers get excited because it suggests that another world is nearby.
The Five-hundred-meter Aperture Spherical radio Telescope (FAST), under construction in Guizhou Province in southern China, will be able to see more than
Astronomers using NASA's Hubble Space Telescope have ruled out an alternate theory on the nature of dark energy after recalculating the expansion rate of the universe to unprecedented accuracy.
The various spiral arm segments of the Sunflower galaxy, also known as Messier 63, show up vividly in a new image taken in infrared light by NASA
New observations with the Very Long Baseline Array have made the farthest direct distance measurement ever, a key step toward understanding the mysterious Dark Energy that constitutes some 70 percent of the Universe. Other observations are redrawing the map of our home Galaxy and promise to revise our understanding of extrasolar planets.
(PhysOrg.com) -- Proving that a lot of little things can go a long way, a group of astronomers have revealed plans to build and install a radio telescope array out of thousands of small inexpensive dishes, spread out over thousands of miles of remote territory.
NASA's Fermi Gamma-ray Space Telescope unveiled a previously unseen structure centered on the Milky Way. The feature spans 50,000 light-years.
