What does the Hubble Ultra Deep Field image show?
Called the Hubble Ultra Deep Field (HUDF), the image contains as many as 10,000 galaxies of all shapes, sizes, colors, and ages. Taken by NASA’s Hubble Space Telescope, this benchmark view represents a “core sample” of galaxies at various distances and therefore different eras in our universe’s history.
What are we seeing in the Hubble Deep Field?
We can see how they changed through time. With the Hubble Deep Field, we reach back nearly to the time when galaxies emerged from the chaos of the big bang. By observing at these wavelengths, researchers get a direct look at which galaxies are forming stars and where the stars are forming within those galaxies.
What is Hubble space telescope limiting magnitude?
The Hubble telescope can detect objects as faint as a magnitude of +31.5, and the James Webb Space Telescope (operating in the infrared spectrum) is expected to have a magnitude limit of 34th magnitude.
How many objects are in the Hubble Deep Field?
3,000 objects
The field is so small that only a few foreground stars in the Milky Way lie within it; thus, almost all of the 3,000 objects in the image are galaxies, some of which are among the youngest and most distant known.
What’s the deepest part of space?
The Hubble Ultra Deep Field (in its eXtreme version) is the deepest view of the universe yet obtained … and will be, until JADES takes over. It stretches approximately 13 billion light-years and includes approximately 10,000 galaxies.
What is the deepest picture of space?
The HUDF is the deepest image of the universe ever taken and has been used to search for galaxies that existed between 400 and 800 million years after the Big Bang (redshifts between 7 and 12).
How do you find the magnitude of a telescope?
An approximate formula for determining the visual limiting magnitude of a telescope is 7.5 + 5 log aperture (in cm). This is the formula that we use with all of the telescopes we carry, so that our published specs will be consistent from aperture to aperture, from manufacturer to manufacturer.
How does the apparent magnitude scale work?
Apparent magnitude m of a star is a number that tells how bright that star appears at its great distance from Earth. The scale is “backwards” and logarithmic. Larger magnitudes correspond to fainter stars. Note that brightness is another way to say the flux of light, in Watts per square meter, coming towards us.
Where is the Hubble Ultra Deep Field?
constellation Fornax
The Hubble Ultra-Deep Field (HUDF) is an image of a small region of space in the constellation Fornax, containing an estimated 10,000 galaxies.
