Was Kepler's supernova unusually powerful?
(Phys.org)—In 1604, a new star appeared in the night sky that was much brighter than Jupiter and dimmed over several weeks. This event was witnessed by sky watchers including the famous astronomer Johannes ...
Suzaku 'post-mortem' yields insight into Kepler's supernova
(Phys.org) —An exploding star observed in 1604 by the German astronomer Johannes Kepler held a greater fraction of heavy elements than the sun, according to an analysis of X-ray observations from the Japan-led ...
Scientists develop ultra-thin solar cells
Austrian and Japanese researchers on Wednesday unveiled solar cells thinner than a thread of spider silk that are flexible enough to be wrapped around a single human hair.
New suspect identified in supernova explosion
(Phys.org) —Supernovas are often thought of as the tremendous explosions that mark the ends of massive stars' lives. While this is true, not all supernovas occur in this fashion. A common supernova class, ...
Graphene photodetector integrated into computer chip
The novel material graphene and its technological applications are studied at the Vienna University of Technology. Now scientists succeeded in combining graphene light detectors with semiconductor chips.
New imaging device that is flexible, flat, and transparent
(Phys.org)—Digital cameras, medical scanners, and other imaging technologies have advanced considerably during the past decade. Continuing this pace of innovation, an Austrian research team has developed ...
Cosmic turbulences result in star and black hole formation
Just how stars and black holes in the Universe are able to form from rotating matter is one of the big questions of astrophysics. What we do know is that magnetic fields figure prominently into the picture. ...
Famous supernova reveals clues about crucial cosmic distance markers
(Phys.org) —A new study using data from NASA's Chandra X-ray Observatory points to the origin of a famous supernova. This supernova, discovered in 1604 by Johannes Kepler, belongs to an important class ...
Molecules form 2-D patterns never before observed: Experiments produce elusive 5-vertex tilings
Tessellation patterns that have fascinated mathematicians since Johannes Kepler worked out their systematics 400 years ago – and that more recently have caught the eye of both artists and crystallographers ...
Fermions exhibit collective behavior in unexpected situations
Some people like company. Others prefer to be alone. The same holds true for the particles that constitute the matter around us: Some, called bosons, like to act in unison with others. Others, called fermions, have a mind ...
European space freighter is destroyed after mission
A robot freighter was destroyed on Tuesday in a scheduled operation after a successful mission to supply the International Space Station (ISS), the European Space Agency (ESA) said.
European space freighter poised for suicide plunge
A European freighter will be destroyed by atmospheric burn-up next week after completing its supply mission to mankind's orbital outpost, the European Space Agency (ESA) said on Friday.
Astronomers seize last chance in lifetime for Venus Transit
Astronomers are gearing for one the rarest events in the Solar System: an alignment of Earth, Venus and the Sun that will not be seen for another 105 years.
Faith helped steer astronomy professor who made planet discovery
It was a Friday afternoon, Aug. 31 of last year, that Eric Agol, a 42-year-old associate professor of astronomy at the University of Washington, looked at his computer screen and saw something astounding.
