Caught in the act | ESA/Hubble

The NASA/ESA Hubble Space Telescope has captured the image of the first-ever predicted supernova explosion. The reappearance of the Refsdal supernova was calculated from different models of the galaxy cluster whose immense gravity is warping the supernova’s light.

Fermi Telescope Caps First Year With Glimpse of Space-Time (w/ Video)

This view of the gamma-ray sky constructed from one year of Fermi LAT observations is the best view of the extreme universe to date. The map shows the rate at which the LAT detects gamma rays with energies above 300 million electron volts — about 120 million times the energy of visible light — from different sky directions. Brighter colors equal higher rates. Credit: NASA/DOE/Fermi LAT Collaboration.

The solar system might be a lot hairier than we thought. A new study publishing this week in the Astrophysical Journal by Gary Prézeau of NASA’s Jet Propulsion Laboratory, Pasadena, California, proposes the existence of long filaments of dark matter, or “hairs.”

Kaon decay – asymmetry between matter & antimatter

 

Ground-breaking research could challenge underlying principles of physics

Dr Nicolas Garron, a Research Fellow in the Centre of Mathematical Sciences, has helped to devise the first theoretical calculation of how the behavior of kaons differs when matter – anything with mass, such as the world around us – is swapped out for antimatter – made out of similar particles with opposite charge.

X-ray microscope reveals 'solitons,' a special type of magnetic wave

An ultrafast camera coupled to a custom-built X-ray microscope at SLAC’s Stanford Synchrotron Radiation Lightsource allowed researchers to produce a six-frame “movie” of the soliton’s motion. It took about 12 hours to record enough X-ray data to produce the movie. Credit: Stefano Bonetti/Stockholm University

Einstein was no lone genius

Marcel Grossmann (left) and Michele Besso (right), university friends of Albert Einstein (centre), both made important contributions to general relativity.

Lesser-known and junior colleagues helped the great physicist to piece together his general theory of relativity, explain Michel Janssen and Jürgen Renn.

Fermi mission finds hints of gamma-ray cycle in an active galaxy

Fermi mission finds hints of gamma-ray cycle in an active galaxy

Astronomers using data from NASA’s Fermi Gamma-ray Space Telescope have detected hints of periodic changes in the brightness of a so-called “active” galaxy, whose emissions are powered by a supersized black hole. If confirmed, the discovery would mark the first years-long cyclic gamma-ray emission ever detected from any galaxy, which could provide new insights into physical processes near the black hole.

What every physicist should know about string theory

physics today

Some of nature’s rhymes—the appearance of similar structures in different areas of physics—underlie the way that string theory potentially unifies gravity with the other forces of nature and eliminates the ultraviolet divergences that plague quantum gravity.

Physics Crowdfunding Hackathon

Fiat Physica, the world’s premier crowdfunding platform, devoted to the success of physics, astronomy and space exploration, will celebrate its launch with a hackathon on Saturday October 24 at General Assembly. This hackathon invites scientists, educators, technologists, and communicators to participate in a day-long workshop where the Fiat Physica team and other experts in the field will help scientists craft crowdfunding campaigns to raise money for their research.
 
If you plan on attending please make sure that you have registered both on the General Assembly site (http://physicshack2015.com) as well as the Eventbrite page (https://physicshack.eventbrite.com) which keeps track of how you will be participating.
