Alien Jellyfish Inspired By Ocean Life
2012-07-09 09:33:18

With some inspiration from the studies of ocean life forms, a British space expert envisages alien lifeforms that resemble jellyfish with organs developed to ingest methane and other chemicals for its nutrition, keeping aloft by means of dangling onion-like buoyancy bags, and communicating with pulses of light.

Incoming Coronal Mass Ejection Coming On June 16

The sun is a ferocious, hot mess, and this week it showed off through a coronal mass ejection just how messy it can get. An active region on the sun fired off two M-class flares and two coronal mass ejections (CMEs) this week.

Wise Finds Fewer Brown Dwarfs Than Expected

Astronomers are getting to know the neighbors better. Our sun resides within a spiral arm of our Milky Way galaxy about two-thirds of the way out from the center. It lives in a fairly calm, suburb-like area with an average number of stellar residents.

Centaurus Constellation -- Centaurus (the centaur) was one of the 48 constellations listed by Ptolemy, and counts also among the 88 modern constellations. A constellation of the southern hemisphere, mentioned by Eudoxus (4th century B.C.) and Aratus (3rd century B.C.), Ptolemy catalogued thirty-seven stars in it. It contains Proxima Centauri, the red dwarf that is the nearest known star (other than the Sun) to Earth, as well as Alpha Centauri, which is a double star to which Proxima...

Red Dwarf -- A red dwarf is a small star on the main sequence, either late K or M spectral type. They have a diameter and mass of less than one-third that of the Sun (down to 0.08 solar masses, which are Brown dwarves) and a surface temperature of less than 3,500 K. They emit little light, sometimes as little as 1/10,000th that of the sun. Due to the slow rate at which they burn hydrogen red dwarves have a enormous lifespan, estimates range from a tens of billions up to trillions of...

Proxima Centauri -- The red dwarf star Proxima Centauri (also Alpha Centauri C), part of the Alpha Centauri star system, is the nearest star to our Earth other than the Sun. Proxima Centauri is roughly 4.22 light years from Earth, 270,000 times as far as the sun. Its apparent magnitude is 11 (very weak, as red dwarfs in general are: far too weak to be observable with the naked eye). Proxima Centauri has often been suggested as a logical first destination for interstellar travel....

Brown Dwarf -- Brown dwarfs are a special type of low-mass star (approximately 13-70 Jupiter masses) that do not have nuclear fusion occurring in their cores during their time on the main sequence. Early in their development most brown dwarf stars do have lithium fusion in their cores, and a lack of lithium is a test for low-mass objects that are suspected of being brown dwarfs. Many brown dwarfs continue to glow in the red and infrared after their lithium is exhausted. This glow is...

Alpha Centauri -- Alpha Centauri is the brightest star system in the southern constellation of Centaurus, and is the third brightest in the entire night sky (although too far south to be visible in most of the northern hemisphere). It is also the closest star system to Earth. It bears the proper name Rigil Kentaurus (often shortened to Rigil Kent), meaning "foot of the centaur" in Arabic, but is nonetheless usually referred to by its Bayer designation Alpha Centauri. Alpha Centauri is...

bretelles
  • In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
The word 'bretelles' comes from a French word meaning 'braces'.
