ALMA captures duo of titanic galaxies in extreme starbursting merger
Nov 14, 2017 (SPX)
These so-called hyper-luminous starburst galaxies are exceedingly rare at this epoch of cosmic history - near the time when galaxies first formed - and may repr...
The path length of light in opaque media
Nov 13, 2017 (SPX)
Professor Stefan Rotter and his team (TU Wien, Austria) predicted this counter-intuitive result together with French colleagues three years ago. Now he and his ...
Winds blowing off a dying star
Nov 13, 2017 (SPX)
Formation of dust around AGB stars has been considered to play an important role in triggering acceleration of stellar wind, but the detailed mechanism of this ...
Tracking down the origins of gold
Nov 10, 2017 (SPX)
Astrophysicist Dr. Andreas Bauswein from the Heidelberg Institute for Theoretical Studies (HITS) has successfully acquired a Starting Grant from the European Re...
Hubble Spots Expanding Light Echo Around Supernova
Nov 10, 2017 (SPX)
The supernova, called SN 2014J, occurred at the upper right of M82, and is marked by an "X." The supernova was discovered on Jan. 21, 2014. The inset images at ...
Star kills its 'congenial' to form together a dwarf-binary system
Nov 10, 2017 (SPX)
What makes this binary system so unique is its origin: the white dwarf's existence was prematurely cut off by its companion, a brown dwarf, which caused its ear...
Scientists narrow down the search for dark photons using decade-old particle collider data
Nov 09, 2017 (SPX)
A fresh analysis of this data, co-led by physicists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), limits some of the hidin...
Zombie Star Exploded, Survived and Exploded Again
Nov 09, 2017 (SPX)
An international team of astronomers including Carnegie's Nick Konidaris and Benjamin Shappee discovered a star that exploded multiple times over a period of 50...
The star that would not die
Nov 09, 2017 (SPX)
When the supernova, named iPTF14hls, was discovered in September of 2014 by the Palomar Transient Factory, it looked like an ordinary supernova. Several months ...
Astronomers discover a star that would not die
Nov 09, 2017 (SPX)
Supernovae, the explosions of stars, have been observed in the thousands and in all cases they marked the death of a star. But in a study published in the journ...
Diffused light shows clear structures
Nov 09, 2017 (SPX)
The team of scientists have successfully developed and tested a method which is considerably more effective than conventional procedures. The researchers' findi...
Unistellar: Response to eVscope Confirms Interest in Citizen Science
Nov 09, 2017 (SPX)
The campaign gave supporters the opportunity to order an eVscope, a revolutionary, electronics-based telescope that offers unprecedented views of distant object...
NIST researchers develop color filters that respond to the angle of incident light
Nov 09, 2017 (SPX)
Viewed from afar, the device, referred to as a directional color filter, resembles a diffraction grating, a flat metal surface containing parallel grooves or sl...
ALMA's image of red giant star gives a surprising glimpse of the sun's future
Nov 08, 2017 (SPX)
A team of astronomers led by Wouter Vlemmings, Chalmers University of Technology, have used the telescope ALMA to make the sharpest observations yet of a star w...
Giant Magellan Telescope Organization Casts Fifth Mirror
Nov 08, 2017 (SPX)
The process of "casting" the giant mirror involves melting nearly 20 tons of glass in a spinning furnace. Once cooled, the glass disk will be polished to its fi...
Shedding light on the mystery of matter accretion in young stars
Nov 08, 2017 (SPX)
An experiment replicating the accretion phenomenon on a star was conducted in a laboratory. Researchers took a close look at what happens when a laser-produced ...
ALMA discovers cold dust around nearest star
Nov 08, 2017 (SPX)
The lead author of the new study, Guillem Anglada, from the Instituto de Astrofisica de Andalucia (CSIC), Granada, Spain, explains the significance of this find...
Shocking results of galaxy-cluster collisions
Nov 08, 2017 (SPX)
The region is collectively known as Abell 2744, some 4 billion light-years from Earth. The radio portion of the image comes from new observations made with the ...
