Black holes are some of the most bizarre and mysterious phenomena in the Universe – they have captivated the imaginations of scientists and the public alike, and have been featured in many science fiction movies and stories. […]

Planetary Swing: Spitzer Space Telescope Probes Extreme Climates on Hot Jupiters and Super Earths

A simulation showing the turbulent atmosphere of exoplanet HD 80606b, based on data gathered with the Spitzer space telescope. This hot Jupiter-type world has one of the most elongated orbits known for an exoplanet, one that resembles the orbits of comets in our Solar System.

Seen from the perspective of […]

Kepler Observes Supernova's Shockwave in Visible Light for First Time

An artist’s impression of a supernova explosion. With the help of NASA’s Kepler space telescope, astronomers were able to observe for the first time the exact moment when the shockwave from a supernova reaches the surface of the progenitor star just before the latter explodes.

One of the most impressive […]

Size Matters: Astronomers Discover Rare, 'Super Spiral' Galaxies

A team of astronomers has recently discovered a total of 53 ‘super spiral’ galaxies which are enormous in size, three of which are shown in the image above. The galaxies shown at the left and center images also exhibit a double nucleus, which could be the result of a past galactic merger. Image Credit: […]

'We did it!' Gravitational Waves Confirmed for First Time After Being Predicted by Einstein

For a long time now, there have been theories and rumors regarding the possible existence of another planet in our Solar System, far […]

Mystery Deepens: New Study Shows Comets Don't Explain Odd Dimming of Kepler's 'Weird Star'

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 to […]

Record-Shattering, Ultra-Luminous Hypernova Explosion Stuns Astronomers, Poses New Cosmic Mystery

An artist’s impression of the record-breakingly powerful, superluminous supernova ASASSN-15lh that was recently discovered by the Automated Survey for SuperNovae (ASAS-SN), as it would appear from a hypothetical exoplanet located about 10,000 light years away in the host galaxy of the hypernova.

New Study Suggests Earth May Be Surrounded by Long Hair-Like Filaments of Dark Matter

A new theoretical study has shown that Earth may be surrounded by long and very dense hair-like filaments of dark matter, which could potentially be directly observed by dedicated space-based dark matter detectors. Image Credit: NASA/JPL-Caltech

When hunting for dark matter, where would the best place to search for it be? The answer according […]
