Cosmic Dance Helps Galaxies Lose Weight
Oct 4th
ScienceDaily (July 29, 2009) — A study published July 30 in the journal Nature offers an explanation for the origin of dwarf spheroidal galaxies. The research may settle an outstanding puzzle in understanding galaxy formation.
Dwarf spheroidal galaxies are small and very faint, containing few stars relative to their total mass. They appear to be made mostly of dark matter – a mysterious substance detectable only by its gravitational influence, which outweighs normal matter by a factor of five to one in the universe as a whole.
D’Onghia and her colleagues used computer simulations to examine two scenarios for the formation of dwarf spheroidals: 1) an encounter between two dwarf galaxies far from giants like the Milky Way, with the dwarf spheroidal later accreted into the Milky Way, and 2) an encounter between a dwarf galaxy and the forming Milky Way in the early universe.

Extrasolar Hot Jupiter

ScienceDaily (Aug. 27, 2009) — A planet has been discovered with ten times the mass of Jupiter, but which orbits its star in less than one Earth-day.
The discovery, reported in this week’s Nature by Coel Hellier, of Keele University in the UK, and colleagues, poses a challenge to our understanding of tidal interactions in planetary systems.
The planet, called WASP-18b, belongs to a now-common class of extrasolar planets known as ‘hot Jupiters’ — massive planets that are thought to have formed far from their host stars, and migrated inwards over time. WASP-18b is so massive, and so close to its star — only about three stellar radii away — that tidal interactions between star and planet should have caused the planet to spiral inwards to its destruction in less than a million years.

This is a sticky post!!! Make sure it sticks!
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
This should then split into another page with images and other things…
