Can we visit other galaxies? Nope, not yet! But we can still study other galaxies using powerful telescopes.

Quiz yourself about other space knowledge in the “How Do We Know?” section of #ViewSpace: viewspace.org/video_library?ta

An illustration with text. Top left, a black and white picture of a minotaur. Top right, a color picture of a galaxy. Text below: “myth” versus “reality” in two columns. On the Myth side, there is text beneath that says, “We can study other galaxies by visiting them.” On the Reality side, the text beneath says, “Other galaxies are too far away to visit. Even if you could travel at the speed of light, it would take millions to billions of years to reach most other galaxies. The closest galaxies to our own Milky Way are dwarf galaxies thousands of light-years away. We study other galaxies from afar, using powerful space telescopes like Hubble, Chandra, Spitzer, and Webb.”

Examine the case of the “Blue Lurker,” a rare class of star observed by Hubble.

Almost everything we know about Altair, a bright star in the constellation Aquila, comes from studying its light. This #ViewSpace interactive will show you how we study stars by observing images and spectra: bit.ly/4gy1xHH

Break down each wavelength of light in #ViewSpace to see what appears when galaxy Centaurus A—shown here in a multiwavelength composite image—is viewed in X-ray, radio, infrared, and visible light: bit.ly/3xQTC8h

The background of this image is filled with colorful dots, representing distant galaxies and stars. In the middle is a bright pink X-like object, formed from a galaxy’s dusty disk and jets. The thin, wavy line of dark red material that forms the galaxy’s disk stretches diagonally across the center and extends from slightly lower left to slightly upper right. The jets shoot out above and below the disk, forming a line that goes from the top left of the image to the bottom right. They are puffy, swelling more closer to the ends away from the center. In the center where the jets and disk cross is a small bright white spot. Hazy light brown concentric rings of light extend from the center, each ring becoming more transparent toward the image’s edges.
