2. APOD: 2015 December 24 - Star Colors and Pinyon Pine
... 2015 December 24 . Star Colors and Pinyon Pine . ... Explanation: Beautiful, luminous decorations on this pinyon pine tree are actually bright stars in the constellation Scorpius and the faint glow of the central Milky Way. Captured in June from the north rim of the Grand Canyon of planet Earth, the shallow, close focus image has rendered pine needles on the tree branch sharp, but blurred the distant stars, their light smeared into remarkably colorful disks. ...

6. Magnitudes and Colors
Astronomers usually measure the flux of an object by collecting light with a telescope, sending it through a known filter, and then determining the power. ... But astronomers usually give their photometric results in terms of magnitudes. ... Astronomers define an absolute magnitude that is independent of the distance of a star and only depends on the intrinsic properties of the object: the absolute magnitude is the magnitude the star would have if it were 10 parsecs away from the Earth. ...

Left: An image in the near infrared (1.65 ЮМm) around RY Tauri, using a special mode of the Subaru HiCIAO coronagraph, the polarized intensity image. This type of observation is preferred for faint emissions associated with scattered light around planet-forming disks, as there is less light from the much brighter star. ... A white ellipse shows the position of the midplane of the disk, which is observed at millimeter wavelengths. ... Right: Schematic view of the observed infrared light. ...

... Energy . ... Solar Wind . ... Field . ... The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. For some reason the field slows down the flow of heat from the Sun's interior and keeps sunspots slightly cooler than their surroundings. ... Solar Eclipses . ...

17. The Sun
The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...
