Captured just days after its discovery, the images offer the clearest view yet of this rare visitor from beyond our solar ...

NASA launching SPHEREx and PUNCH missions this weekend A NASA space telescope on a mission to map millions of galaxies has turned on its detectors for the first time, capturing images of tens of ...

Previously, when NASA’s now-retired Spitzer Space Telescope observed the Sombrero galaxy, the outer ring appeared smooth, but Webb’s new imagery reveals the complex, clumpy nature of the dusty ...

Data from the James Webb Space Telescope indicate that a galaxy known as GN-z11 has a supermassive black hole at its center — one that's far more massive than astronomers expected.

The Kepler Space Telescope, named for astronomer Johannes Kepler, was NASA's first exoplanet hunting telescope. It launched on March 6, 2009, with the goal of observing more than 100,000 stars in ...

The infrared telescope and its detectors have a distinct design of three cone-shaped layers of photon shields that allow it to operate at temperatures of minus 350 degrees Fahrenheit.

Ten areas in the sky were selected as “deep fields” that the Dark Energy Camera imaged several times during the survey, ...

The world's largest telescope captured a deep-space nebula — an interstellar cloud of gas and dust that can produce new stars — in stunning detail, providing the first close-up view to date of ...

A new telescope could launch as early as late February. SPHEREx will look into deep space and also search for organic molecules.

A 2.4-inch refracting telescope, for example, should never use more than 120-power magnification (the general rule of thumb is 50-power per inch of aperture).
