  2. Radio window - Wikipedia

    en.wikipedia.org/wiki/Radio_window

    The radio window is the region of the radio spectrum that penetrate the Earth's atmosphere. Typically, the lower limit of the radio window's range has a value of about 10 MHz (λ ≈ 30 m); the best upper limit achievable from optimal terrestrial observation sites is equal to approximately 1 THz (λ ≈ 0.3 mm).

  3. Atmospheric window - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_window

    Out of an average 340 watts per square meter (W/m 2) of solar irradiance at the top of the atmosphere, about 200 W/m 2 reaches the surface via windows, mostly the optical and infrared. Also, out of about 340 W/m 2 of reflected shortwave (105 W/m 2 ) plus outgoing longwave radiation (235 W/m 2 ), 80-100 W/m 2 exits to space through the infrared ...

    Akatsuki left the Sagamihara Campus on 17 March 2010, and arrived at the Tanegashima Space Center's Spacecraft Test and Assembly Building 2 on 19 March. On 4 May, Akatsuki was encapsulated inside the large payload fairing of the H-IIA rocket that launched the spacecraft, along with the IKAROS solar sail, on a 6-month journey to Venus. On 9 May ...

    A Journey to the Center of the Earth game for Sega Genesis was planned but never released. [13] A board game adaptation of the book designed by Rüdiger Dorn was released by Kosmos in 2008. [14] Caedmon Records released an abridged recording of Journey to the Center of the Earth read by James Mason, in the 1960s.

  6. Optical window - Wikipedia

    en.wikipedia.org/wiki/Optical_window

    The optical atmospheric window is the optical portion of the electromagnetic spectrum that passes through the Earth's atmosphere, excluding its infrared part; [10] although, as mentioned before, the optical spectrum also includes the IR spectrum and thus the optical window could include the infrared window (8 – 14 μm), the latter is ...

  7. Visible-light astronomy - Wikipedia

    en.wikipedia.org/wiki/Visible-light_astronomy

    A diagram of the electromagnetic spectrum with the Earth's atmospheric transmittance (or opacity) and the types of telescopes used to image parts of the spectrum.. Visible-light astronomy encompasses a wide variety of astronomical observation via telescopes that are sensitive in the range of visible light (optical telescopes).

  8. Exploration of Io - Wikipedia

    en.wikipedia.org/wiki/Exploration_of_Io

    2 atmosphere froze out enough to produce a layer several millimeters thick, which seemed unlikely. [1] Radio telescopic observations revealed Io's influence on the Jovian magnetosphere , as demonstrated by decametric wavelength bursts tied to the orbital period of Io (Io-DAM), suggesting an electrodynamic coupling between the two worlds.

  9. LHS 475 b - Wikipedia

    en.wikipedia.org/wiki/LHS_475_b

    LHS 475 b is a terrestrial planet orbiting the star LHS 475 which is about 40.7 light years away, in the constellation of Octans. [2] [3] It was the first extrasolar planet to be confirmed by the James Webb Space Telescope. [4]
