Antennae Starwave Formation
Supernova explosions are enriching the intergalactic gas with elements like oxygen, iron, and silicon that will be incorporated into new generations of stars and planets X-ray: NASA/CXC/SAO/J.DePasquale; IR: NASA/JPL-Caltech; Optical: NASA/STScI A beautiful new image of two colliding galaxies has been released by NASA’s Great Observatories. The Antennae galaxies, located about 62 million light years…

Pushing Back Time
Credit: X-ray: NASA/CXC/PSU/S.Park & D.Burrows.; Optical: NASA/STScI/CfA/P.Challis February 24, 2007 marks the 20th anniversary of one of the most spectacular events observed by astronomers in modern times, Supernova 1987A. The destruction of a massive star in the Large Magellanic Cloud, a nearby galaxy, spawned detailed observations by many different telescopes, including NASA’s Chandra X-ray Observatory…

Spherical Cows and their X-ray Sources
As a layman I find this of particular importance when we send our vision out amongst the stars, all the while looking at the substance of these events “within the larger context of the universe.” While each particular event is revealed through Chandra’s catalogued linked below it helps me to see them within that universe…

Spherical Cows
Cartoon Model of a SNR(Supernova Remnants) When scientists refer to a spherical cow, we are poking fun at ourselves. We are admitting that some of our models or descriptions of things are far more simple than the actual object, like to say that a cow has a spherical shape. The phenomena we study are often…

SuperFluids
MIT physicists create new form of matter by Lori Valigra, Special to MIT News Office June 22, 2005 A superfluid gas can flow without resistance. It can be clearly distinguished from a normal gas when it is rotated. A normal gas rotates like an ordinary object, but a superfluid can only rotate when it forms…

First Stars Behind the Scene
There are several recognized processes from the early universe that leave relic effects setting the stage for galaxy formation and evolution. We deal here with the first generarion of stars, primordial nucleosynthesis, the epoch of recombination, and the thermal history of various cosmic backgrounds. Part of understanding the time line is first knowing where the…

The Geometrics Behind the Supernova and it’s History
It is not always easy for people to see what lies behind the wonderful beauty of images that we take from the satellite measures of space, and it’s dynamical events illustrated in Cassiopeia A. There before you is this majestic image of beauty, as we wonder about it’s dynamics. These Spitzer Space Telescope images, taken…

Hubble Finds Evidence for Dark Energy in the Young Universe
I had to go back to the article for some further reading. These snapshots, taken by NASA’s Hubble Space Telescope, reveal five supernovae, or exploding stars, and their host galaxies. The arrows in the top row of images point to the supernovae. The bottom row shows the host galaxies before or after the stars exploded.…

Cosmic ray spallation
As this NASA chart indicates, 70 percent or more of the universe consists of dark energy, about which we know next to nothing Other explanations of dark energy, called “quintessence,” originate from theoretical high-energy physics. In addition to baryons, photons, neutrinos, and cold dark matter, quintessence posits a fifth kind of matter (hence the name),…

Three Ring Circus: Dark Energy
“Observations always involve theory.”Edwin Hubble Hopefully some day, I will be accepted as a student of this universe, and it’s intrigue? Sometimes it is necessary to understand that having come to different consclusion about the geometry of this universe that underneath the complexity of these equations a schematic drawing of reality is unfolding? I think…
