... The planets are still growing slowly as comets and meteoroids collide with them. ... In the 1950s, American astronomer Fred Whipple suggested that comets are dirty snowballs: clumps of ice mixed with interplanetary dust. ... For most of its orbit, a comet remains far from the Sun, little more than the dirty snowball that it is -- what is usually called a bare nucleus. ... As Comet Hyakutake approached the Sun, jets of dust erupted from the Sun-facing side of its nucleus. ...

... ASTEROID’S MOONS : DISCOVERY BY RADAR . ... Moons of known asteroids have a low position ambiguity, which makes their discovery with powerful ground-based radar much easier than the discovery of new asteroids or other objects of Solar System. ... The other technique is a direct detection of radar echo from an asteroid moon. ... However, the diameter of a ground-based fully-steerable reflector is limited by 120-150 m to make it possible to perform two different functions: focusing and tracking (fig. ...

Richard Carrington in England observes a violent and rapid eruption near a sunspot; 17 hours later a large magnetic storm begins. ... Using it he observes a solar flare and confirms the connection between flares and magnetic storms. ... Explorer 1, launched by the US January 31, observes the radiation belt; Explorer 3, launched in March, comes up with the first clear evidence for its existence....

... The effect is strongest in the most evolved, high-latitude supergiant V5112 Sgr=IRAS19500-1709, which has an extended structured envelope (Figs.1 and 2). In the optical spectrum of this object, the BaII ion lines are split into three components (Figs.3 and 4). ... Thus, we discovered for the first time the enrichment of the stellar envelope with heavy metals produced at the AGB stage. ... Detection of heavy-metal lines in the spectrum of the circumstellar envelope of a post-AGB star. ...

... Discovered originally in Fermi gamma-ray telescope data and labelled the Fermi Bubbles , the polarized radio counterparts of these structures were discovered with the Parkes telescope in 2012. ... The shocks are sites for cosmic ray acceleration. Emission from these cosmic rays explains the WMAP Haze observed at microwave wavelengths around the Galactic centre as well as the Bubbles wider-scale radio polarization and gamma-ray emission. ...
