How black holes feed quasars

Star Stuff - Tue, 11/25/2014 - 20:00
There's growing evidence that the strange physics in black holes provides the energy to power quasars. Also; how the Sun causes lightning on Earth, And NASA's new Orion spacecraft arrives at the Kennedy Space Centre for its first test flight.

Converting Human-Generated Waste Into Fuel in Space

Science Daily - Tue, 11/25/2014 - 15:46
Who would've known human waste could be used to propel spacecraft from the moon back to Earth? Researchers responded to the call from NASA and came up with a process to convert waste to methane and propel spacecraft to Earth.

How to estimate the magnetic field of an exoplanet

Science Daily - Thu, 11/20/2014 - 14:18
Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they managed to estimate the value of the magnetic moment of the planet HD 209458b.

It's filamentary: How galaxies evolve in the cosmic web

Science Daily - Thu, 11/20/2014 - 13:34
How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? Astronomers now propose some answers. The researchers highlight the role of the 'cosmic web' -- a large-scale web-like structure comprised of galaxies -- on the evolution of galaxies that took place in the distant universe, a few billion years after the Big Bang.

Riddle of the missing stars: Hubble observations cast further doubt on how globular clusters formed

Science Daily - Thu, 11/20/2014 - 11:32
Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling. New observations of globular clusters in a small galaxy show they are very similar to those found in the Milky Way, and so must have formed in a similar way.

Unravelling the mystery of gamma-ray bursts with kilometer-scale microphones

Science Daily - Thu, 11/20/2014 - 08:19
A team of scientists hopes to trace the origins of gamma-ray bursts with the aid of giant space ‘microphones’. It's hoped the kilometer-scale microphones will detect gravitational waves created by black holes, and shed light on the origins of the Universe.

Sun's rotating 'magnet' pulls lightning towards UK

Science Daily - Wed, 11/19/2014 - 20:48
The sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper atmosphere.

NASA's Swift mission probes an exotic object: 'Kicked' black hole or mega star?

Science Daily - Wed, 11/19/2014 - 17:50
Astronomers have discovered an unusual source of light in a galaxy some 90 million light-years away. The dwarf galaxy Markarian 177 (center) and its unusual source SDSS1133 (blue) lie 90 million light-years away. The galaxies are located in the bowl of the Big Dipper, a well-known star pattern in the constellation Ursa Major.
