It is one thing to observe the periodic dimming of a star’s light, as NASA’s Kepler Space Telescope has done for thousands of planet “candidates” since its launch in 2009. However, to confirm that such...
Number of potentially habitable planets in our galaxy: Tens of billions

One month with the Samsung Galaxy S7 Edge: Can the gimmicks help set this phone apart?
The smartphone market is getting boring. Great cameras, killer screens and powerful processors abound, making it easy to find a phone that will fit your needs, but also overwhelming you with options that are hard to tell...
A 17-billion-solar-mass black hole in a group galaxy with a diffuse core
Quasars are associated with and powered by the accretion of material onto massive black holes; the detection of highly luminous quasars with redshifts greater than z = 6 suggests that black holes of up to ten billion solar masses already existed 13 billion years ago. Two possible present-day ‘dormant’ descendants of this population of ‘active’ black holes have been found in the galaxies NGC 3842 and...

R-process enrichment from a single event in an ancient dwarf galaxy
Elements heavier than zinc are synthesized through the rapid (r) and slow (s) neutron-capture processes. The main site of production of the r-process elements (such as europium) has been debated for nearly 60 years. Initial studies of trends in chemical abundances in old Milky Way halo stars suggested that these elements are produced continually, in sites such as core-collapse supernovae. But evidence from the...

The host galaxy of a fast radio burst
In recent years, millisecond-duration radio signals originating in distant galaxies appear to have been discovered in the so-called fast radio bursts. These signals are dispersed according to a precise physical law and this dispersion is a key observable quantity, which, in tandem with a redshift measurement, can be used for fundamental physical investigations. Every fast radio burst has a dispersion measurement, but none before...
Galaxy S7 and S7 Edge hands on: So good you can almost forgive TouchWiz
Whitepages partners with Samsung to pre-install caller ID software on Galaxy S7 smartphones
Samsung is partnering with Whitepages to offer customers a spam-blocking caller ID feature for its new Galaxy S7 smartphone.
Seattle-based Whitepages announced today that its caller ID and spam detection technology will come pre-installed on Galaxy S7 devices in 16 countries.
Whitepages has information about more...
