Nebula surrounding VY Canis Majoris, which is one of largest known stars. Carina Nebula: 460 ly (140 pc) [39] H II region: Nearest giant H II region to Earth Dragonfish Nebula: 450 ly (140 pc) [40] Emission nebula: N119: 430–570 ly (131–175 pc) [41] H II region: Peculiar S-shape RCW 49: 350 ly (110 pc) [42] H II region: Soul Nebula: 330 ly ...
[37] [56] At the time of its publication, the estimated parallax from the Hipparcos mission was 7.63 ± 1.64 mas, yielding an estimated radius for Betelgeuse of 3.6 AU. However, an infrared interferometric study published in 2009 announced that the star had shrunk by 15% since 1993 at an increasing rate without a significant diminution in ...
The taxonomy of the Cyanea species is not fully agreed upon; some zoologists have suggested that all species within the genus should be treated as one. Two distinct taxa, however, occur together in at least the eastern North Atlantic, with the blue jellyfish (Cyanea lamarckii Péron & Lesueur, 1810) differing in color (blue, not red) and smaller size (10–20 cm [3 + 7 ⁄ 8 – 7 + 7 ⁄ 8 ...
AMD64 (also variously referred to by AMD in their literature and documentation as “AMD 64-bit Technology” and “AMD x86-64 Architecture”) was created as an alternative to the radically different IA-64 architecture designed by Intel and Hewlett-Packard, which was backward-incompatible with IA-32, the 32-bit version of the x86 architecture.
A compiled Java program can run on a 32- or 64-bit Java virtual machine with no modification. The lengths and precision of all the built-in types, such as char, short, int, long, float, and double, and the types that can be used as array indices, are specified by the standard and are not dependent on the underlying architecture. Java programs ...
The intensity of the HF signal in the ionosphere is less than 3 μW/cm 2, tens of thousands of times less than the Sun's natural electromagnetic radiation reaching the Earth and hundreds of times less than even the normal random variations in intensity of the Sun's natural ultraviolet (UV) energy which creates the ionosphere. The small effects ...
The 1990 storm was an example of a Great White Spot, a short-lived phenomenon that occurs once every Saturnian year, roughly every 30 Earth years, around the time of the northern hemisphere's summer solstice. [63] Previous Great White Spots were observed in 1876, 1903, 1933, and 1960, with the 1933 storm being the best observed. [64]
A white dwarf is very dense: in an Earth sized volume, it packs a mass that is comparable to the Sun. No nuclear fusion takes place in a white dwarf; what light it radiates is from its residual heat. [1] The nearest known white dwarf is Sirius B, at 8.6 light years, the smaller component of the Sirius binary star.
