Cepheids in Spiral Galaxy NGC 5584

Cepheids in Spiral Galaxy NGC 5584
This illustration shows the location of Cepheid variables found in the spiral galaxy NGC 5584. Ultraviolet, visible, and infrared data taken with Hubble's Wide Field Camera 3 in 2010 reveal Cepheids of varying periods. Those stars with periods of less than 30 days and between 30 and 60 days are marked with green and blue circles, respectively. A small number of Cepheids, with periods larger than 60 days, are marked in red.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    14h 22m 23.76s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    00° 23' 15.61"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Virgo
  • Distance
    DistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
    About 72 million light-years (22 million parsecs)
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    The image is 2.4 arcminutes (50,000 light-years or 15,000 parsecs) wide.

About the Data

  • Data Description
    Data DescriptionProposal: A description of the observations, their scientific justification, and the links to the data available in the science archive.
    Science Team: The astronomers who planned the observations and analyzed the data. "PI" refers to the Principal Investigator.
    The image was created from Hubble data from proposal 11570: A. Riess (STScI/JHU), L. Macri (Texas A&M University), C. Kochanek and K. Stanek (Ohio State University), A. Filippenko and W. Li (University of California, Berkeley), S. Casertano and H. Ferguson (STScI), and L. Greenhill (Harvard-Smithsonian Center for Astrophysics). The science team comprises: A. Riess (STScI/JHU), L. Macri (Texas A&M University), S. Casertano (STScI), H. Lampeitl (University of Portsmouth, UK), H. Ferguson (STScI), A. Filippenko (University of California, Berkeley), S. Jha (Rutgers University), W. Li (University of California, Berkeley), and R. Chornock (Harvard-Smithsonian Center for Astrophysics). Note: Hubble data of NGC 5584 taken with WFC3/IR filters, along with numerous other galaxies, were used in these science results.

Cepheids in Spiral Galaxy NGC 5584
Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

This image is a composite of separate exposures acquired by the WFC3 instrument on HST. Several filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: White: F350LP (Long Pass) Blue: F555W (V) Orange: F814W (I)

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
