It may sound cliche, but the question ‘Are we alone?’ is still one that captures the imagination of many people, including of course, scientists. With the now regular discovery of exoplanets orbiting other stars, the prospect that there may be other intelligent life out […]

As has been reported previously on AmericaSpace, and elsewhere, there is something weird going on around a star which is a little over 1,400 light-years away. Astronomers are still baffled as […]

The SETI Institute has recently undergone a search for alien radio signals around the star KIC 8462852, whose mysterious brightness fluctuations have been considered to be the workings of an extraterrestrial civilisation. Following a thoroiugh search in a wide range of frequencies, SETI reported that it has detected no such signals that could […]

An artist’s impression of a supermassive black hole. Astronomers believe that such objects lie at the centers of most galaxies in the Universe. A recent study, which was undertaken with the help of the Event Horizon Telescope, has provided new indirect evidence that indeed this is the case. Image Credit: ESO/L. Calçada

By Leonidas Papadopoulos, on April 21st, 2015 An artist’s illustration of the vicinity of the supermassive black hole in the center of the Milky Way galaxy, known as Sagittarius A* . Astronomers have discovered a population of more than 150 massive young stars (shown as blue dots) in recent years that orbit within 2 light-years from the black hole. Newer […]

By Leonidas Papadopoulos, on April 13th, 2015 Artist’s impression of the protoplanetary disk surrounding the young star MWC 480. Astronomers using the Atacama Large Millimeter/submillimeter Array, or ALMA, have detected the complex organic molecule methyl cyanide in the outer reaches of the star’s protoplanetary disk, where comets are believed to form. This discovery suggests that complex organic chemistry and potentially […]

By Leonidas Papadopoulos, on April 4th, 2015 A dramatic night-time image of the 64-m Parkes radio telescope in Australia, under the splenor of the Milky Way. The iconic telescope has detected during the last decade a total of 10 mysterious cosmic radio flashes, known as ‘fast radio bursts’. A new study now suggests that these astrophysical sources exhibit a surprising […]
