Even small asteroids can do a lot of damage—and new research shows the James Webb Space Telescope is adept at spotting the tiniest of space rocks. A time-lapse of images from NASA’s James Webb ...

The James Webb Space Telescope has captured an image of a baby, Milky Way-like galaxy that formed more than 13 billion years ago. This "Firefly Sparkle" galaxy could reveal how our own galaxy evolved.

After the Hubble Space Telescope studied the oldest-known exoplanet in the galaxy, scientists used the James Webb Space Telescope to learn how planets were able to form in the early universe.

Often referred to as field scopes or digiscopes, they bridge the gap between a monocular and a telescope, offering impressive magnifications while remaining compact and portable. The standout ...

In the years since, researchers using the Hubble Space Telescope have observed that the current expansion rate, called the Hubble constant, is faster than what standard cosmology models estimate ...

Astronomers may have discovered the oldest objects ever observed by pushing the James Webb Space Telescope (JWST) to its limits. These incredibly distant structures date back to only 200 million years ...

New measurements from the Webb telescope – Nasa’s most powerful space observatory – could help explain one of the deepest mysteries of the cosmos, according to the researchers behind them.

Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...

Webb Telescope Confirms the Universe Is Expanding at an Unexpected Rate By Will Dunham WASHINGTON (Reuters) - Fresh corroboration of the perplexing observation that the universe is expanding more ...

New observational data from the James Webb Space Telescope (JWST) has confirmed that prior measurements of distances between nearby stars and galaxies made by the Hubble Space Telescope are not in ...

If all goes according to plan, the anticipated development timeline for the ELT will see the telescope's secondary mirror (M2) completed in 2025. The 14-foot (4.25-meter) mirror — the largest ...
