Study says gravity and Higgs boson interacted to save the universe

One second after the Big Bang, the Higgs boson should have caused a Big Crunch, collapsing the universe to nothing. But gravity saved the day.

View larger.| See the little white dot of the planet Venus in the upper right of this photo?  It'll be back to your evening sky in early December.  Helio de Carvalho Vital captured this image on November 18, 2014 from Rio de Janeiro, Brazil.  He wrote, "I managed to capture Venus as it is starting its return to dusk, despite the fact that it is still at a mere 6.2° distance from the sun. 
The photos show it a  few minutes before setting behind the  northern side of the 1,021-meter high Tijuca Peak, located some 6.5 km away. It was deeply immersed in the intense glare of the sun, that would set some 13 minutes later."

Subaru Telescope detects sudden appearance of 7 galaxies in early universe

Japanese astronomers probing deeply back into our universe’s early history have found 7 galaxies at a time when the universe was only 700 million years old.

View larger. | This artist's impression shows schematically the mysterious alignments between the spin axes of quasars and the large-scale structures that they inhabit that observations with ESO’s Very Large Telescope have revealed. These alignments are over billions of light-years and are the largest known in the universe.  The large-scale structure is shown in blue and quasars are marked in white with the rotation axes of their black holes indicated with a line.  This picture is for illustration only and does not depict the real distribution of galaxies and quasars.  Image via ESO/M. Kornmesser

Bizarre black hole alignments over billions of light-years

The black holes are central to quasars in the early universe. Researchers say the probability that their aligned spin is the result of chance is less than 1%.

Asteroid Vesta now has its own geologic maps

Vesta is revealed as a world in space – albeit a little world – in these new maps of its surface. Scientists say the maps of Vesta reveals its history.

EarthSky Facebook friend Mitchell Spector captured this image of the sunspot formerly known as AR2192 - now known as AR 2209 - on November 16, 2014, the same day it emitted an M class flare.

Sunspot comes back around, produces M5 flare

AR 2192 was the largest sunspot in 24 years. The sun’s rotation carried it out of view, but now it’s back, renamed, and is still producing solar flares.

See Andromeda galaxy tonight. Moon and Spica before dawn

Last week, we showed you how to use the constellation Cassiopeia to find the Andromeda galaxy. But there’s another way, using the Great Square of Pegasus.

Study suggests 2014 ocean surface temps warmest on record

2014 is still on track to be the warmest year on record, and ocean surface temperatures appear to be rising as well.
