... 2002 January 1 . The Secret of the Black Aurora . ... Explanation: What causes black aurora? These gaps in normal bright aurora are frequently recorded but rarely questioned. Recent research using data from four Cluster spacecraft orbiting the Earth has now likely found the secret: black auroras are actually anti-auroras. ... In black anti-auroras, however, negatively charged particles are sucked out from the Earth's ionosphere along adjoining magnetic field lines. ... About APOD | ...

... Using the amazing power of the ALMA telescope, astronomers have unlocked some of the mysteries surrounding supermassive black holes that lie at the centre of galaxies. ... Well, supermassive black holes are the largest type of black hole . ... Astronomers are almost certain that we have a supermassive black hole at the centre of our own galaxy, the Milky Way. In fact, it is now widely accepted that there is a supermassive black hole at the centre of most galaxies. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... Another option is to buy slides of astronomical objects at different wavelengths to show students why astronomers use different bands of the spectrum to bring out specific characteristics in celestial objects. ... He then uses the camera to scan the entire classroom, asking students to identify what they are seeing. ...

... Moon . ... What can astronomers tell us about the different colors on the surface of Jupiter's moon Europa? ... We can use the colors of Europa s surface to tell us about the chemical compounds that make up the surface and subsurface of the jovian moon. Even before the first spacecraft made a close visit to Europa, astronomers on Earth used telescopes to study the moon and were able to use a technique called spectroscopy to determine that Europa s surface is composed mostly of water ice. ...

... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ...

... NGC 3603: X-Rays From A Starburst Cluster . ... A mere 20,000 light-years from the Sun lies the NGC 3603 star cluster, a resident of the nearby Carina spiral arm of our Milky Way galaxy. ... Planetary nebula Abell 39, now six light-years across, was once a sun-like star's outer atmosphere expelled thousands of years ago. ... The brightest of these new stars are so hot that they light up this spiral galaxy not only in blue light, but in light so blue humans can't see it: ultraviolet. ...

Embargoed until 11am, Thursday 6th May SOME BLACK HOLES ARE PINK A group of Australian astronomers have found that some black holes are bright pink! ... They have such intense gravity fields that they even suck in light. ... Black holes like this are called quasars, and were first discovered in the 1960s."Until now", Dr Francis said, "only blue quasars had been seen, and it was believed that the debris swirling around black holes should emit only blue light, not pink." ...

... Posts tagged ?black box? ...
