SN Primo Is Farthest Type Ia Supernova Discovered


Supernova Primo originated 9 billion years ago, when its progenitor star exploded. The light was captured by the Hubble Space Telescope by a three-year project specifically trying to find Type Ia supernovae. These types of supernovae are paramount in order to discover more about the inflationary nature of our universe.

Scientists Convene to Take a Picture of the Supermassive Black Hole at the Center of the Milky Way


It might sound like science-fiction, but on Wednesday January 18th, astronomers, physicists, and scientists will convene in Tucson, Arizona, to discuss a feat that would have been considered ludicrous just a couple of years ago. They plan on taking a picture of a black hole.

Black Hole Fires Cosmic Bullets of Ionized Gases


Using the Very Large Baseline Array, astronomers have managed to capture an image of a black hole firing two gigantic pockets of ionized gas at almost a quarter the speed of light. The resulting cosmic explosion produces as much energy in an hour as our sun emits in five years.

The Puzzle of an Eternally-Existing, Self-Reproducing, and Inflationary Universe


There are quite a few challenges for cosmologists trying to discover evidence of what it was like early in the life of our universe, but while the inflationary universe scenario was an almost universally accepted model, there are still problems, especially for observational astrophysicists who don’t see any evidence of a flat universe, as inflation would predict.

What is the Matter Gap?

What does it mean to cross the matter gap, or beyond the matter gap? Are we talking about non-baryonic matter, ie exotic matter, which could be a candidate for dark matter? Can something actually come from beyond the matter gap? What are the properties beyond the matter gap?

I’ve searched, but the most relevant thing that I could find is “filling the matter gap”, ie finding other types of matter, matter different from the baryonic matter that we know.

Large Scale Fractal Universe

Is the universe fractal, even on large scales? That’s the question that some Russian and Italian scientists have put forth recently. They think it is. Other scientists aren’t so sure. (via kottke)
