Dark Energy Survey Discovers Exotic Supernova
2014-06-26 03:28:35

Royal Astronomical Society The first images taken by the Dark Energy Survey (DES) after the survey began in August 2013 have revealed a rare, ‘superluminous’ supernova that erupted in a galaxy 7.8 billion light years away. The stellar explosion, called DES13S2cmm, easily outshines most galaxies in the Universe and could still be seen in the data six months later, at the end of the first of what will be five years of observing by DES. The event was discovered by Andreas Papadopoulos, a...

Supernova Legacy Survey Astronomers Reveal New Class Of Supernovae
2013-12-19 04:50:57

April Flowers for redOrbit.com - Your Universe Online Two of the brightest and most distant supernovae ever recorded have been discovered by astronomers affiliated with the Supernova Legacy Survey (SNLS). The findings, published in The Astrophysical Journal, reveal that the supernovae are 10 billion light-years away and a hundred times more luminous than a normal supernova. The extreme luminosity of these supernovae cannot be explained by the mechanism that powers most supernovae —...

Dark Energy Survey Will Look For Supernovae
2013-07-01 18:32:12

John P. Mills, Ph.D. for redOrbit.com - Your Universe Online The greatest cosmological puzzle of the 21st century continues to be to measure, characterize and understand the source of dark energy, the apparent force that is driving the accelerating expansion of the Universe. One of the problems is that in order to make accurate measurements of the expansion rate, astronomers must measure the motions of distant galaxies, some near the very edge of the known Universe. At such great...

Distant Type Ia Supernova Magnified Through Gravitational Lensing
2013-04-23 18:32:44

Lee Rannals for redOrbit.com — Your Universe Online Researchers at the Kavli IPMU, led by Robert Quimby, have discovered the first ever Type Ia supernova (SNIa), extraordinarily magnified by a gravitational lens. Scientists wrote in the Astrophysics Journal Letters they discovered the supernova, PS1-10afx, with the Panoramic Survey Telescope & Rapid Response System 1 (Pan-STARRS1). The supernova exploded over 9 billion years ago, making it a much further object than most...

Dark Energy Camera Dedication Amping Up Next Week
2012-11-02 12:51:23

Lee Rannals for redOrbit.com — Your Universe Online Today marks the 50th anniversary celebration of Cerro Tololo Inter-American Observatory (CTIO), while next week is the dedication of a new instrument for the observatory. The Dark Energy Camera was installed on the Victor M. Blanco telescope at CTIO, and it will be conducting powerful surveys by collecting light from 100,000 galaxies located up to 8 billion light years away. The camera has 62 charged-coupled devices with an...

Ancient Starlight Recorded By Dark Energy Camera
2012-09-18 04:19:18

April Flowers for redOrbit.com - Your Universe Online Approximately 8 billion years ago, the light from distant galaxies began streaming towards Earth. Now, at a mountaintop observatory in Chile, the newly constructed Dark Energy Camera (DECam), the most powerful sky-mapping machine ever created, has captured that ancient starlight and recorded it for the first time. Early on September 12, 2012, the DECam, mounted atop the Victor Blanco Telescope at the Cerro Tololo Inter-American...
