The latest measurements with the Hubble Space Telescope suggest the universe is expanding faster than scientists' models predict—a hint that some unknown ingredient could be at work in the cosmos.
Riess and his team analyzed Hubble observations of two different types of "cosmic yardsticks" — Type Ia supernovas (stellar explosions of consistent luminosity) and Cepheid stars, which pulse at rates that are related to their true brightness. The Planck number, however, is a projection that'...
but the vast majority are dim and reddish. The reddest blobs are the most distant galaxies in our observable universe; their light has been stretched (red-shifted) after traveling for billions of years through an expanding cosmos. These galaxies are the most ancient galaxies that formed within ...
While it is now in the process of becoming a white dwarf, we can still enjoy the product of this expanding shell of gas that is often called the “Skull Nebula.” Friday, November 2 –Celestial scenery alert! If you’re up when the Moon rises, be sure to look for the close pairing...

Please know this is not a flame. You are no different than all of us in saying that it is space that is expanding. That is because matter is not moving apart as it moves away at higher speeds. But that leaves the question, why then is space not expanding locally?
Transposable elements can be viewed as natural DNA transfer vehicles that, similar to integrating viruses, are capable of efficient genomic insertion. The mobility of class II transposable elements (DNA transposons) can be controlled by conditionally pro

The universe is expanding, but the rate of that expansion is proving to be elusive. A new measurement of the universe’s expansion rate falls between two previously established rates, leading to more questions than answers. About a century ago, Carnegie Institute of Science astronomer Edwin Hubble...
