NASA's Chandra finds massive black holes common in early universe

Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA

UK and European space agencies give a go for Skylon spaceplane

After 30 years of development, the UK and European space agencies have given a go for the Skylon Spaceplane.

Seeing the planets for the trees

A recent study says that a particular mathematical technique could be used to detect forests on extrasolar planets.

Planets that have no stars: New class of planets discovered

(PhysOrg.com) -- University of Notre Dame astronomer David Bennett is co-author of a new paper describing the discovery of a new class of planets -- dark, isolated Jupiter-mass bodies floating alone in space, far from any host star. Bennett and the team of astronomers involved in the discovery believe that the planets were most likely ejected from developing planetary systems.

Mini black holes that look like atoms could pass through Earth daily

(PhysOrg.com) -- In a new study, scientists have proposed that mini black holes may interact with matter very differently than previously thought. If the proposal is correct, it would mean that the time it would take for a mini black hole to swallow the Earth would be many orders of magnitude longer than the age of the Universe.

New mineral discovered: one of earliest minerals formed in solar system

A team of scientists has discovered a new mineral -- krotite, one of the earliest minerals formed in our solar system. It is the main component of an unusual inclusion embedded in a meteorite (NWA 1934), found in northwest Africa. These objects, known as refractory inclusions, are thought to be the first planetary materials formed in our solar system, dating back to before the formation of Earth and the other planets.

Supernova and star birth in the Meathook galaxy

The Meathook Galaxy, or NGC 2442, has a dramatically lopsided shape. One spiral arm is tightly folded in on itself and host to a recent supernova, while the other, dotted with recent star formation, extends far out from the nucleus. The NASA/ESA Hubble Space Telescope and the MPG/ESO 2.2-meter telescope have captured two contrasting views of this asymmetric spiral galaxy.

Densest known rocky planet: Astronomers unveil portrait of 'super-exotic super-Earth'

(PhysOrg.com) -- An international team of astronomers today revealed details of a "super-exotic" exoplanet that would make the planet Pandora in the movie Avatar pale in comparison.

Primordial weirdness: Did the early universe have 1 dimension?

A disturbed galactic duo

The galaxies in this cosmic pairing, captured by the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile, display some curious features, demonstrating that each member of the duo is close enough to feel the distorting gravitational influence of the other. The gravitational tug of war has warped the spiral shape of one galaxy, NGC 3169, and fragmented the dust lanes in its companion NGC 3166. Meanwhile, a third, smaller galaxy to the lower right, NGC 3165, has a front-row seat to the gravitational twisting and pulling of its bigger neighbours.

Best-ever look at pulsars: LOFAR takes the pulse of the radio sky

A powerful new telescope is allowing an international team of scientists to have their
