New Data Suggests We Don’t Live in a Void, and Supports Dark Energy
Entire galaxies feel the heat from newborn stars: Bursts of star birth can curtail future galaxy growth
(Phys.org) —Astronomers using the NASA/ESA Hubble Space Telescope have shown for the first time that bursts of star formation have a major impact far beyond the boundaries of their host galaxy. These energetic ...
Massive galaxy had intense burst of star formation when universe was only 6 percent of current age
(Phys.org) —Smaller begets bigger. Such is often the case for galaxies, at least: the first galaxies were small, then eventually merged together to form the behemoths we see in the present universe.
Hubble telescope breaks record for farthest supernova
(Phys.org) —The supernova, designated SN UDS10Wil, belongs to a special class of exploding stars known as Type Ia supernovae. These bright beacons are prized by astronomers because they can be used as a ...
ALMA finds 'monster' starburst galaxies in the early universe
Some of the brightest galaxies in the universe – infant galaxies that churned out tens of thousands of stars each year at the dawn of the universe – evolved much sooner and in greater numbers than previously ...
Dark energy alternatives to Einstein are running out of room
(Phys.org)—Research by University of Arizona astronomy professor Rodger Thompson finds that a popular alternative to Albert Einstein's theory for the acceleration of the expansion of the universe does not ...
Big Bang under the microscope
(Phys.org)—Scientists have replaced the telescope with the microscope: Using the similarities between the structure of a crystal and the state of the cosmos in the early universe, they have explored a yet ...
The beginning of everything: A new paradigm shift for the infant universe
(Phys.org)—A new paradigm for understanding the earliest eras in the history of the universe has been developed by scientists at Penn State University. Using techniques from an area of modern physics called ...
Explosion of galaxy formation lit up early universe
(Phys.org)—New data from the South Pole Telescope indicates that the birth of the first massive galaxies that lit up the early universe was an explosive event, happening faster and ending sooner than suspected.
Earliest spiral galaxy ever seen: a shocking discovery
(Phys.org) -- Astronomers have witnessed for the first time a spiral galaxy in the early universe, billions of years before many other spiral galaxies formed. In findings reported July 19 in the journal Nature, the as ...
Most quasars live on snacks, not large meals
(Phys.org) -- Black holes in the early universe needed a few snacks rather than one giant meal to fuel their quasars and help them grow, according to observations from NASA's Spitzer and Hubble space telescopes.
