  2. Herbig–Haro object - Wikipedia

    en.wikipedia.org/wiki/Herbig–Haro_object

    The total mass being ejected by stars to form typical HH objects is estimated to be of the order of 10 −8 to 10 −6 M ☉ per year, [16] a very small amount of material compared to the mass of the stars themselves [19] but amounting to about 1–10% of the total mass accreted by the source stars in a year. [20]

  3. Visible-light astronomy - Wikipedia

    en.wikipedia.org/wiki/Visible-light_astronomy

    The Hubble Space Telescope's four main instruments observe in the near ultraviolet, visible, and near infrared spectra. Hubble's images are some of the most detailed images ever taken, leading to many breakthroughs in astrophysics , such as accurately determining the rate of expansion of the universe .

  4. Monochrome-astrophotography-techniques - Wikipedia

    en.wikipedia.org/wiki/Monochrome...

    In order to produce a colour image using a monochrome sensor, three monochrome images must be produced and combined to produce a colour image. The three monochrome images are mapped to the respective red, green and blue channels.

  5. Hubble volume - Wikipedia

    en.wikipedia.org/wiki/Hubble_volume

    Visualization of the whole observable universe.The inner blue ring indicates the approximate size of the Hubble volume. In cosmology, a Hubble volume (named for the astronomer Edwin Hubble) or Hubble sphere, Hubble bubble, subluminal sphere, causal sphere and sphere of causality is a spherical region of the observable universe surrounding an observer beyond which objects recede from that ...

    en.wikipedia.org/wiki/HH_24-26

    An image of HH 24 taken by the Hubble Space Telescope. The image of HH 24 taken by the Hubble Space Telescope is probably the most well known image of this Herbig-Haro object. HH 24 resembles a lightsaber from the science fiction movies Star Wars and the Hubble image was published during the release of Star Wars Episode VII: The Force Awakens. [6]

    The Hubble and Webb data give a value averaging about 73, with a range of about 70-76. The Big Bang event 13-14 billion years ago initiated the universe, and it has been expanding ever since.

  8. Cosmological horizon - Wikipedia

    en.wikipedia.org/wiki/Cosmological_horizon

    Hubble radius, Hubble sphere (not to be confused with a Hubble bubble), Hubble volume, or Hubble horizon is a conceptual horizon defining the boundary between particles that are moving slower and faster than the speed of light relative to an observer at one given time. Note that this does not mean the particle is unobservable; the light from ...

  9. Mini-Hubble will scan dim stars to see if they can support life

    The aim is to find so-called M Dwarfs, stars 20 times dimmer than our sun, and see if they emit too much radiation to support life on other worlds. Mini-Hubble will scan dim stars to see if they ...
