The mystery surrounding KIC 8462852 may not involve comets after all, but it is still an enigma for astronomers. Image Credit: NASA/JPL-Caltech
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 […]

Planetary debris disks, or protoplanetary disks, are some of the most interesting phenomena in astronomy – these giant clouds of dust and gas surrounding young stars are the birthplaces of new planets. Now, […]

By Leonidas Papadopoulos, on April 29th, 2015 A stunning image of a giant cluster of about 3,000 stars, called Westerlund 2, which lies approximately 20,000 light-years away from Earth. This image was officially selected by NASA to commemorate the 25th anniversary since the launch of the Hubble Space Telescope, on April 24, 1990. Image Credit: NASA, ESA, the Hubble Heritage […]

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 March 28th, 2015 A montage of Jupiter and its volcanic moon Io, as seen by NASA’s New Horizons spacecraft on its way to Pluto. The results of a new study indicate that the massive gas giant fundamentally altered the evolution of the early Solar System, by destroying any “Super-Earth”-type planets that may have formed, while opening […]

By Leonidas Papadopoulos, on October 1st, 2014 An artist’s concept of the formation process of the Solar System out of an interstellar molecular cloud and its enrichment with water. A recent study has indicated that up to half of Earth’s water is older than the Sun itself, likely originating in that cold molecular cloud that spawned our Solar System. Image […]

By Paul Scott Anderson, on August 29th, 2014 Artist’s conception of an asteroid collision around the Sun-like star NGC 2547-ID8. Such impacts around young stars lead to planetary formation later on. Image Credit: NASA/JPL-Caltech
Solar systems, including ours, are thought to begin as massive clouds of dust and gas surrounding young stars; over billions of years, planets form from repeated impacts […]

By Jason Rhian, on November 21st, 2012 This false-color near-infrared image has been processed to remove most of the scattered light from the star Kappa Andromedae (masked out at center).The “super-Jupiter” companion, Kappa Andromedae b (upper left), lies at a projected distance of about 55 times the average distance between Earth and the sun and about 1.8 times farther than […]
