Kepler bags huge haul of planets

Astronomy News - 26 February 2014 - 9:33pm
The science team sifting data from Nasa's Kepler space telescope says it has identified 715 new planets beyond our Solar System.

Hundreds of mini solar systems found in the Milky Way

Astronomy News - 26 February 2014 - 7:00pm
More than 700 possible planets found by a NASA telescope have been verified as real, and most live in scaled-down versions of our inner solar system
    





A Breakthrough in Planet Discoveries

Astronomy News - 26 February 2014 - 6:04pm
Today, NASA announced a breakthrough addition to the catalog of new planets. Researchers using Kepler have confirmed 715 new worlds, almost quadrupling the number of planets previously confirmed by the planet-hunting spacecraft. Some of the new worlds are similar in size to Earth and orbit in the habitable zone of their parent stars.

This is a Hubble Space Telescope composite image of a supernova explosion designated SN 2014J in the galaxy M82, at a distance of approximately 11.5 million light-years from Earth. Astronomers using a ground-based telescope discovered the explosion on January 21, 2014. This Hubble photograph was taken on January 31, as the supernova approached its peak brightness.

NASA's Kepler Mission Announces a Planet Bonanza, 715 New Worlds

Astronomy News - 26 February 2014 - 5:00pm
NASA's Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system.

Herschel:Bullying black holes force galaxies to stay red and dead

Astronomy News - 25 February 2014 - 4:15pm
Herschel has discovered massive elliptical galaxies in the nearby Universe containing plenty of cold gas, even though the galaxies fail to produce new stars. Comparison with other data suggests that, while hot gas cools down in these galaxies, stars do not form because jets from the central supermassive black hole heat or stir up the gas and prevent it from turning into stars.

Grant helps gravitational waves hunt

The remnant of a merger between two dwarf galaxies in Andromeda II

The remnant of a merger between two dwarf galaxies in Andromeda II

Nature 507, 7492 (2014). doi:10.1038/nature12995

Authors: N. C. Amorisco, N. W. Evans & G. van de Ven

Driven by gravity, massive structures like galaxies and clusters of galaxies are believed to grow continuously through hierarchical merging and accretion of smaller systems. Observational evidence of accretion events is provided by the coherent stellar streams crossing the outer haloes of massive galaxies, such as the Milky Way or Andromeda. At similar mass scales, around 1011 solar masses in stars, further evidence of merging activity is also ample. Mergers of lower-mass galaxies are expected within the hierarchical process of galaxy formation, but have hitherto not been seen for galaxies with less than about 109 solar masses in stars. Here we report the kinematic detection of a stellar stream in one of the satellite galaxies of Andromeda, the dwarf spheroidal Andromeda II, which has a mass of only 107 solar masses in stars. The properties of the stream show that we are observing the remnant of a merger between two dwarf galaxies. This had a drastic influence on the dynamics of the remnant, which is now rotating around its projected major axis. The stellar stream in Andromeda II illustrates the scale-free character of the formation of galaxies, down to the lowest galactic mass scales.
